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...

Nandroid backups get corrupted right after the process is done, broken SD?

I used to make backups before with amon-ra-recovery 2.0.0 and everything was great, I could restore everytime I wanted and I didn't have any issues.
Suddenly, since some time, things started to go wrong. Not a single nandroid backup I do is working, they all get corrupted immediately and I get that "error, run nandroid via adb" or something similar, error, you probably know it. The md5 is corrupted on most of the .img files and even if I change them to be correct, I manage to go through the entire restore process, but the system is whacked, it either goes into bootloop, either it boots fine but sd-ext is gone and all the screens are empty like I never had any widgets or app shortcuts on them, and sometimes I'm lucky and I have only some minor bugs which are fixed by reflashing the ROM without wiping anything.
I can't remember if this happend since I updated to ra recovery 2.0.1 (I am now back to 2.0.0) or since I changed the SD card into a class 6 one. The partition is 1gb ext4, it is done properly (I repartitioned with ra recovery 2.0.1 a few weeks ago and still problems, the previous partition was made by g-parted), SD seems to be working well, I really have no idea what is causing this.
I am willing to try clockwork mod recovery today, can anyone provide a source for their latest version please? I can't find anything on google except for some old threads.

which card are u using ?

The new one. 8gb class 6, I don't see what difference does it make...

I am now getting a problem that I also had before I repartitioned the SD card last time, after doing a nandroid backup today, now I am getting an error telling me that card is read-only. I can't mount it to PC (I mean i can have disk drive on phone but when trying to open it from PC it says its not found). Last time I had this problem I couldn't delete sd-ext.rar from the nandroid backup folder, it said it was corrupted and I couldn't do anything, just like now. Can't connect to PC, can't unmount the SD from phone and on available space it says read-only, that is the problem, how can I solve this? I'm really not in the mood to repartition all over, is the card broken?
Edit: I am now going to report a problem that I've only had on this SD card so far, never on the old one that comes with the phone. So I rebooted the phone and now the sd-ext isn't recognized on the phone, apps that were installed on it don't show up in app-drawer and some widgets that were also on sd-ext don't display on the screen, says problem loading widget. I had this problem once in a while with most of the ROMs I tried, ever since I switched to this card (i think it happened in the 1st day this card arrived). When I reboot the phone (either I normally reboot it or the battery dies), sometimes this thing pops up. It doesn't say any errors, its just that the ext partition isn't recognized, but the fat32 is ok, I can access the SD card's content via root explorer for example and I can even mount it to the PC and explore it from the notebook, but ext partition isn't recognized.
Like I said, this is only on this new card, doesn't happen to the old one, and it happened even in the 1st day it came and was inserted in the phone. I also repartitioned it and same problem, both times did it correctly exactly as I did with the old card and everything was ok on that one.

The exact problem is "mounted read-only - the sd card has an unexpected problem. Tapping...(can't read any further cause it doesn't fit entirely in the notification bar)". It happens when I try to do a complete titanium backup (for all system data+user apps).

Common any opinions? Im really worried.

So i've done a nandroid backup with clockwork mod 2.5.0.7 and its corrupted as well. Just after it finished the backup, I mounted in usb mass storage mode and went to check the md5 images, they are corrupted. I'm going to make a final repartition today with g-parted, and if it's not gonna work then I will probably switch to my old class 2 card that came with the phone, I'm only dissapointed that I cannot prove this SD card I recently got is broken, the fat32 is working but sd-ext has problems, they probably won't believe this and won't replace it

[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

[Q] SD Card not being read, can't go into clockwork

Hi all,
So I woke up this morning with my phone displaying a notification that my sd card is blank. I've had data2ext installed for about a month now on every other cm7 nightly, the latest being #108. I tried to mount the sd card, only to see the same notification. I've tried rebooting, battery pull, booting without the sd card then inserting it and nothing has changed. I went as far as trying to install the htc 2.2 update... and it failed since I'm not on an htc rom. The weird thing is my "about phone" section still shows 244 mb available of 418 mb total, although this might just be the ram/rom, not data partition... So what can I do? I also tried rebooting into recovery through cm7's power off menu AND rom manager, only to be shown a phone with a red QUESTION mark instead of the triangle and exclamation point. When I tried formatting my sd card, i get a pop-up notice saying "SD card is currently being checked". Help me, xda community. You're my only hope.

I tend to be the guy who asks the more obvious or I guess overlooked stuff... So I will!
Now to me(and I'm no expert here...) but it doesn't sound like a problem with the SD card(or maybe it is!). Have you tried a different SD card? Or using the SD card in a different device?

I didn't have a micro sd card adapter or any other micro sd to try at the time I wrote the OP so I didn't include that in there. I have an adapter now and the computer recognizes a drive there but it only shows the swap volume, I believe (it says I need to format the card, and when I try to it only shows it as being 30.6mb). When I try to format I get a "Windows was unable to complete the format" notification. So yeah, that's where I'm at.

try paragon partition manager, it usually gets the job done for me.

I'm trying to use partition manager, but I still only see 30 mb on the sd card. I'm not exactly sure how to just clear the whole thing of the ext partition and swap volume, though.

can your partition manager delete the swap partition?

Have you tried gparted? that's the only way I could really customize my sd card with the different kinds of partitions.

Partition manager hung while trying to delete the partition.
Gparted failed, I don't remember the exact message on that one.
I tried a different microsd card and it was recognized by the phone, so something weird must've happened to my original one. I guess a year's worth of use is all I can ask for with tech nowadays. Thanks for the help, guys.

Did you use gparted from a live cd, or on a computer actually running linux? I have had gparted live cd's fail me, and then turned right around and had success with gparted installed to ubuntu running on a win xp machine through wubi. Might be worth a shot for you, just make sure to unmount the card in gparted, and to actually make the changes before exiting, as that's an easy mistake to make

I used both, now. I had run redo backup software with gparted off my usb drive and then I installed xubuntu to dual boot my machine, and both only recognize 30 mb of the sd card's 8 gb, so it's only the swap space that was formatted for my data2ext. Thanks guys.

I have deleted every thing on my sd card.

Hi. I did something really stupid as you can tell by the Title of this post. I was using WildChild Rom which i like, but my phone internal memory was filling up even though i have a 8 gb sd card installed. I went into rom manager and partitioned my sd card which as you know deletes everything.
Well now i have done a reset and i now have my phone with WildChild booting up as normal.
I then downloaded all the apps that i had wiped off, but when i try to open up an app i get a message that says " The application Facebook(process com.facebook.katana}has stopped unexpectedly. Please try again.
It says the same for all the apps except the facebook part of the message. I also thing that the sd card is no longer partitioned.
I now that i should not mess about and it won't happen again. Can any one Please help me get my phone working so that i can use it like i should be able to.
Thanks for reading this.
Many thanks.
Alan

I had a similar problem when using RM to partition SDcard. I had to use gparted (Linux) Reboot PC with cd, then removed partitions and made one Fat32 partition. copied files back to SDcard and it worked OK after that.
You can download from Dropbox here
Hope this Helps
