Unmounting SD card when Apps2SD is used

Hi all,
My Desire is rooted and running Leedroid 2.2a with an ext3 partition on my SD card for my apps and cache folders, using the default apps2sd setup with the ROM.
I recently had to re-flash my phone because lots of installed apps went missing; some of them had odd names (the com.android.x.x names) and then it got stuck in a boot loop because it couldn't read the SD card until I formatted it, well actually I had to destroy the ext3 partition. Now I wonder if its because the apps folder is on the SD card/ext3 partition and if I connect the phone to my PC to copy stuff to/from in disk mode it un-mounts the SD card, losing the apps folder and the cache folder.
So far, since flashing, I haven't installed half as much crap on my phone, or dismounted the SD card, but I am worried that it will start to cause problems with the phone if I need to connect via USB/disk drive mode.
Has anyone else had these problems, or know of a 'safe' way to unmount the card without corrupting apps?

It shouldn't corrupt your EXT partition if you mount USB on your device.
AFAIK, if you mount USB, it will only mount the FAT32 partition, the EXT partition will still be available to Android.

Problem has occurred again. My battery went flat on Saturday so the phone turned off. Plugged it in on Saturday night, turned it on, and it stays at the "HTC" white background green text screen.
If I remove the card it boots fine. I mounted the SD card in Ubuntu and I can use the fat32 partition on the card, but the ext3 partition is empty, although if I right click on it and go to properties, it shows that there is 130mb in use on the partition. I cant do anything to the partition because Ubuntu throws some odd error about not being able to mount the partition because its in use, or some other paradoxical scenario...
Annoyed now. Anyone know of a fix? should I copy all the stuff I want off the card, repartition using gparted and try again? I used the ROM Manager app on the phone to prepare the card before. Could it have a bug?? the Ext3 partition is at the end of the drive space, after the fat32 partition. Should I make it the first partition?
Bit of a bump, but it seems I'm not the only one with this issue. Any help is appreciated...
I don't have the card with me now cos I'm at work so I cant do any more tests or try and find a solution.

Have you been able to find a resolution for this, I'm having this exact issue. While I suspect a reformat would address, I don't want to have to deal with this weekly.

No worries, you can mount them fine. but if you take out your sd card out of the phone and turn the phone on, it would turn on and go in a bootloop. but that was just for me.

This is used to happen to me. Stuck in HTC logo on white background. It turned out to be that my sd card was bad partitioned it corrupted.
I fixed it by destroyed all partitions and created only fat32. Then put it back to HTC Desire and had ROM Manager created new ext3 partition.

I have been facing this issue ever since I started trying a2sd+ roms. I created a 1GB ext3 and apps will start disappearing every now and then. If I shutdown the phone and boot it again, then many apps will go missing.
I tried reformatting the sd, wipe and reinstall the rom but no use. Apps will keep disappearing on every reboot. At times all the installed application will be corrupted. i.e they will be listed in application manager as com.android.xx.xx with no icon. Some apps will have the icon and if i select them it will say the application is no longer available.
I have tried different roms with a2sd+ and still have the issue
I have tried different methods of partitioning.. Using acronis disk director in windows, using rom manager, using ubuntu live cd etc.. still the issue is present.
What makes it difficult is that sometimes the ext3 partition gets corrupted.. sometimes the whole sd ext3+fat32 gets corrupted, and I could not find what's wrong.
One final thing left to check is to try with a different sd card. If even that fails, then I have to go back to non-a2sd+ rom and live with low internal memory
Anyone faced this issue and found a solution, please share... I would be grateful...

[Q] TROUBLE: SD Card not partitioning with ROM Manager

Hi
I am having trouble with my SD Card on HTC Desire. The whole problem started this morning, so let me walk you through the whole thing:
I installed CM7 nightly # 24 last night. My phone was working absolutely fine before that. It was late so I just set ROM Manager to make a backup and install the new ROM, and went to bed. When I woke up, it had installed and was working fine. Then I dunno for what reason I had to restart my phone. And when I did, all hell broke loose!
The phone rebooted and gave the error message that there is a blank memory card in the phone!!! I restarted the phone a few more times, took out the card and cleaned it, everything, but it just won't recognize it. I went into recovery and mounted the SD card to connect to computer. But the windows (win7 x64) gave error message that the card has an unrecognized or corrupted file system. Since the only backup I had was on SD card itself, I realized that I was officially screwed.
So I formatted the card in the windows. And now it was showing the full 7.37GB size of the card. Meaning it had also somehow removed the 512MB sd-ext partition I had on it as well. But I said fine, no issues. I can reinstall all the apps and settings etc.
So I installed the CM7 RC2 just to be safe, and went into ROM Manager to make the ext partition. I set it to 512MB, swap size 0MB, and the phone restarted into recovery. It started the partition, but only after 3 or so seconds, it rebooted. I checked, but it hadn't partitioned the card! Weird...
I figured maybe there is a problem with the format Windows did, so I formatted the card once again from recovery. Just to be safe, I wiped everything and reinstalled CM7 RC2. But again, no luck with partitioning. Installed Nightly # 23 to get the latest patches and all, but again no luck.
Now I made a GParted USB boot drive, and tried partitioning with it. But GParted also wont partition it. There was this attention symbol next to the drive. I double clicked the drive and it showed this error in the next window. I took a picture of it from a friend's phone, attached below.
I also took a snapshot from within gparted, but it saved it at some /home/something location and I cannot find it. So if the attached image is not clear enough, or if you know where to look for that snapshot, please let me know and I'll post that. Its not in the boot USB drive or SD Card, and its not in my C: drive either.
I would really appreciate if someone could tell me what the hell is going on with my SD card, and how to fix it. Its a Class 2 card, about 6 months old, and I really hope it isn't dead.

Seriously? No one??

Use the recovery and not Rom Manager or use Gparted of something like Easeus.

I use partition wizard on the computer for partitioning

Desire Crashing frequently(possibly SD related)

Im using a SCLD GSM Desire rooted. Ive used Gingerbread versions of Oxygen, CM7, and currently on MIUI XJ but all freeze up on me often(almost daily) and battery pulls are required to revive.
The freezes do not happen with my 2GB Samsung SD card that came with the phone, but i have used 3 brand new Sandisk 16GB Class 4 SD cards and it crashes on all. This is regardless of whether i have Apps2SD enabled or not. I have looked for last_kmsg after the crashes on CM7 and Oxygen, but the file is never present after a battery pull, if i reboot normally i will get an old last_kmsg file from a few months back.
Was transferring about a gig of music to my phone currently on MIUI XJ 1.12.2, and after i unmounted USB storage it froze up and crashed.
The SD card im currently using was bought at a Virgin store, so im sure it wouldnt be a fake. I hope someone can help troubleshoot, im completely out of ideas!!
Thanks a tone in advance!

which version of MIUI-XJ ie.. A2SD or XPart or D2W?
You can try the following:
1. take nand backup, titanium backup & miui backup
2. download the full rom
3. full wip/wip cache/wip dalvik
4. flash the rom, if you are using cm7r2 hboot you might have to flash market cache fix.
5. let the rom reboot automatically and then let it settle for 15-20 mins
6. go to super user and make sure you enable ROOT permission ON.
7. power-off and power-on, restore your apps.

Thanks for help, appreciate it. I'm running the apps2sd version. Will flash according the method you have suggested. Since I'm on apps2sd, any reformatting/repartitiin you recommend?
Right now for the 16gb class 4 card I have a 1gb ext3 partition created using gparted.

You partitionend your SD card with an FAT32 partition and an EXT partition. If you partitionend in that order and set both partitions primary, you are ready for A2SD/A2SD+.
But please use "A2SD" if you are talking about the script which moves apps automatically to EXT partition, because with "app2sd" you could also mean the FroYo-App2SD and this would be very confusing.

Thanks for the help guys. I repartitioned and reflashed miui according to the procedures you'll mentioned. So far its been running fine, except that I had to use the terminal to reinstall a2sd yesterday, but still no crashes.
So far I have not put any music on the phone since last time it crashed when I filled up the SD. Now that I'm certain the installation is clean after using it for the past few days, ill go ahead and fill up some muswic tomorrow and will post back here.

So the phone crashes everyday now. Noticeably after I enabled a2sd amd moved dalvik.
Need to perform battery pulls to revive the phone and there is no last_kmsg after a reboot.it really kills me everytime I need to pull out the battery, hopefully someone can help troubleshoot!

I have the same problem. It's do not freeze only with stock hboot

Since I'm rooted on custom rom, any way to use a stock hboot now?

yes, you can use any rom with stock hboot. but you will not have much memory for applications

just checked, im on stock hboot.
do you have any other ideas ?

maybe here: http://forum.xda-developers.com/showthread.php?t=1393132

After failing to get 3 of my 16gb sandisk cards working, I tried my Samsung 2gb that came with the phone. This card is working flawlessly for the past month (or however long its been). I'm using a 512mb partition with apps and cache moved to SD with zipalign running and its never crashed.
Does anyone have any ideas? Can't really load any music into such a small card

I have a similar problem.
My phone crashes every time I browse fast trough my picture gallery (I have a lot of pictures) or I use an app that accesses the SD card continuously for several minutes.
For instance, it happens when I do a batch backup with Titanium Backup for all my applications.
I tried the official ROMs and custom ROMs (Cyanogen, DevNull) but the problem persisted.
I sent the device to HTC and they replaced the mainboard.
I tried then the latest official ROM and I faced the same problem.
I switched again to Cyanogen and the same problem appeared.
I have to mention that all this time I used a 8GB SD card (I tried several different cards with the same result) and no App2SD.
Now I'm using the card delivered by HTC together with the device and the problem is gone.
This card is only 4GB (the brand is Samsung) but it seems to work flawless.
My advise is to try a 4GB card and see if it works.

So many bugs... don't know what to do!

Hey everyone ! First I swear I don't post this because I'm too lazy to make a proper search, I've been trying to solve my problems for two days...
Ok, I'll try to sum it up. Sorry if my english goes wrong at some point, I'm french.
Having problems with my micro SD in my Desire, I bought a new one, a kingston 8go, class 10.
My desire was under CM7, was S-OFF with a modified HBOOT. And except from bugs due to my SD (sometimes it would not be recognized), everything was working.
After installing the new micro SD, i did some manipulations: wipe, reinstallation, change of radio/RIL/kernel, and unfortunately ended up with no recovery and others bugs. So I decided (at one point I did stupid stuff) to reinstall RUU aaaand as I was S-OFF with a modified HBOOT, I bricked my phone. BUt after some hours and thanks to the forum, I managed to put back a RUU.
Then I did everything properly: ROOT/S-OFF with revolutionary, wipe, micro SD partition, and CM7 installation.
THen it was hell: I tried everything from regular install to legacy2ext and SimplytoExt etc every time it's really unstable. First the all thing is slow, then I can't flash the google apps, no matter what I try. If I install an app from the market, sometimes it works, sometimes it makes the phone reboot from the boot animation, sometimes it can't install etc.. Google maps was especially unstable.
THen, 10 or 20 manipulations, formatting, reinstallations later, I decided to check other rome, like Oxygen or milwild.
On my last Milwild install, everything is fluid but I can't install a single app (it's just stay on "installation" forever) and I can't wake up the screen after the phone goes to sleep.
Last but not least, my usb charger seems to have transfer problems. It's way to slow and the speed is not constant. During large transfers, comes files go corrupted. Am I usb bricked or something? I tried with another micro SD and it's the same problem;
So here I am, I really don't know what to do more? Any help?
Thanks a lot for your eventual answers!

Seems that installing a RUU solve all the problems for now, I wonder what in the process of putting a custom ROM could have caused so many differents and random problems. I'am doing the all process again to see if I can do it properly.
And again, I installed a custom ROM with CM7 hbott: impossible to download any app and the camera crashed. Any idea?

1. Don't use any D2EXT scripts with Cm7, obviously that's what caused the issue. If you NEED more space (even with cm7 hboot) try using DarkTremor's A2SD.
2. Before you flash a new ROM, do a FULL wipe (either from fastboot or recovery) - erase boot, system, userdata, cache, sd-ext (make sure you have an EXT-n partition on your sd-card, best program to use is gparted)

Desire is designed for class 4 SD card. Although some class 10's will perform at class 10 levels, many do not because of this. Kingston Class 10 being one example (I have one).
My kingston class 10, in Android, performs at class 6 speeds. Which would be ideal, but my class 10 Kingston was slower with data2sd than my class 4 sandisk.

Ok, I might send it back and change for another model then. But still it can't explain the problems I have

I only was using this script to put the apps on the ext partition and I removed it. It's obviously not the problem since they stayed after a clean install.
I always fo a full wipe, I even formated all the partitions and my EXT partition is there and well aligned.
Here I am: I managed to "stabilise" with a gingerbread RUU, rooted and S-OFF with revolutionary.
I used RM recovery (with USB brick fix) and it seemed to help. I don't have any USB transfer problem any more.
The RUU works like a charm.
Then I tried again to install two customs romq, without any script or modification:
-on Milwild, I have still this "deep sleep" problem. I can use the camera, but I can't install any app from the market. It's stays on "installation" forever.
-On CM7 (I put the CM7r2 HBOOT with it) it starts well: I can install google maps. But then I try to open it and it freezes. Then I try to mount the FAT32 partition on my computer and it doesn't work. The cellphone also freezes when I try to reboot (there is the wheel, turning and turning, but nothing happens). SO I forced reboot, and then, google maps had just ... disappeard. I think my phone is haunted...
Isn't it strange that my cellphone is perfectly normal under RUU but can't bear any custom ROM???
I think I'm gonna go back to the RUU and try to use another SD card but I'm sceptical. If someone has a miraculous idea to share, I'll take it!!!
Thanks again

Well, rootSU, it seemed that you found the answer. I put another class 2 sd card and it seems to work again! I just spent hours on this for nothing... The strangest is that the class 10 card work perfectly when out of my phone...
Any advice about a good class 6/8/10 that could improve the performances without crashing like this?
EDIT: last question, I used the app2sd script you introduced, but I can't install any app with it, it says that I've got unsuficiant stockage space Oo.

I use.my class 10 Kingston and it works perfectly as a class 6. Plus its pretty future proof. Just no.good for data2sd.
Should work fine for everything else though

Well, mine didn't worked at all, except the RUUs...strange! I have fully configured my class 2 SD card with simple2ext (only app on the ext partition, not data) and it works.
As I'm tireless, I'll try to put all this via nandroid on my class 10. If it could work like a class 6...

What did you use to partition the Kingston?
Sent from my HTC Desire using Tapatalk

I partitioned it several time, with gparted and recoveries. I'm a bit worried about some part of the hardware managing the connection with the SD card that could be partly broken. I decided to change my first SD card when I first saw a "you need to put an SD card" when I try to take a picture. I had problems with files disappearing from the SD and reappearing. Also I lost some applications that I couldn't appear. I figured the card was dying.
Then I put a new SD card, faster and with larger capacity and everything goes wrong;
Then I put the old one back and... for now, everything works.

[Q] HTC Desire Stuck on Home Page on Start-up - no icons, cannot do anything

Hi Guys,
Apologies in advance. This is my first post here. I've tried to find threads with similar problems to mine but so far I am stuck on how to resolve it.
I inherited a HTC Desire a while ago which came with customised rom (I think it was "insert coin").
However last week I upgraded to a SG3 with the intention of giving the Desire to my sister and it has been all downhill from there.
Ever since I ported my service over to the SG3 and took out the HTC Desire's SD card and old sim, the HTC hasn't been able to start-up.
It turns on, but freezes on the start up home screen (see attachment). No icons are displayed and you can't do anything - not even turn the phone off. You have to pull the battery out to turn it off.
It does this even with another functional sim.
I can still go into HBOOT.
I did a factory reset from here thinking it would go back to stock standard rom. But i'm getting the same thing - freezing on the home screen.
I read about flashing the phone with a recovery image with android flasher. However when I do this, android flasher can't complete the task because it cannot detect my phone via the USB cable (I think the phone is automatically going on "charge only" - and since the screen is frozen, there is a no way of changing this)
I don't know what has gone wrong here so any suggestions would be greatly appreciated.

Firstly, your phone is very easy to fix. Don't panic.
On the hboot screen, you have a "recovery" option. Select it, and post another picture.

Looks like its more of an SD card issue. Put back your earlier SD card or copy its contents to a new one.
Put the SD card back into phone and reboot.
Sent from my HTC Desire

Insert-coin requires a sd-ext partition.
Do you have an ext partition on your sd-card? Is the storage smaller that it should be?
If you put the sd-card back, does it boot normally?

All of the apps were stored on the "old SIM" either put it back (o hope you've not formatted it), or change the Rom

Yes, I thought this too as it was the only thing I could think of that I changed.
I copied the contents of the SD card onto my desktop before I reformatted it (oops!!!) for the SG3.
But when I realised the Desire didn't work, I copied the contents back onto another SD card, put it back in, rebooted, but it didn't work
I can't be 100% certain though that everything was copied back, I could very well have deleted something important. What sort of files would be important for the start up?

The card will have had an ext3 or ext4 partition that you'll have removed. Get a new card (or start again with the one you have) and flash a new Rom, I'd suggest flashing 4ext recovery, creating a 1.5 gb ext4 partition and then the mild wild cm7, you should be up and running within an hour with a stable Rom.

Well... first flash mildwild cm7, to get your phone up and running, and you calm down, then do what frosty said.

You got to partition first before flashing. 1-1.5gb ext4 partition and rest fat32.
You can partition now, wipe everything except for sd card and reflash the ROM again.
