Strange SD card Problem

I have been using Touch 4.02 with an 8gb card for ages now with no troubles then yesterday the storage card is no longer recognised by the phone? I tried the usual soft reset, taking the card out wiping it put it back in still no joy.
Reinstalled the sdhc cab file didnt work, Have just re-flashed with the new diamond look a like rom and still it aint recognising the card.
Has anyone got any ideas??

Probably your card is broken....
Try to insert it in a card reader and see if it recognizes the card....

Yeh will have to wait till I get home not sure my memory card supports SDHC though?

I have a similar problem, and like you I've been happily using an 8gb card for a while, but in the last week it has stopped working correctly.
Occasionally it is fine, but most of the time access to the card is either very slow or it doesn't appear at all.
I've tried the following but with no success:
- Using another MicroSD card (2gb)
- Reading the cards in a card reader and they are fine
- Reinstalling Artemis Touch 4.02 WM6.1
- Formatting the card (FAT32)
- Shimming the MicroSD card with bits of cardboard as I've read there can be a loose fit
- Cleaning the contacts on the card reader
- Pulling the contact pins out a bit to get a better fit
Does anyone have any ideas of anything else to try?

Does WM5torage work?

I did the followings to make my 4GB Micro SD usable by my Artemis:
1-flashed it to FAT32 in my laptop (I Had to format my laptop partition D of my HDD to FAT32 to make the microSD recognizable by my NTFS system).
2-copied the "system folder" from my older 512 MGB card as it is (hidden) to the root of my 4GB
3-The 4GB is readable by my artemis by now.
4-To make sure the crad will be working good in the future, I installed the "Flashcard" Cab in my Artemis and reflashed the card to FAT32, 512 Bytes 4KB clusters.
The card is just fine under Artemis windows, but I gatta take it out when flashing any new ROMs or Radio.
Hope that'd help you.

No - WM5torage behaves the same ... i.e. occasionally works (if the phone can see the card), but most of the time it just reports an error

It is deffothe memory card just put my old 2gb back in the phone and it worked, I have tried the 8gb in my PC card reader and in y camcorder that takes sdhc and neither recognised it.
This explains why my phone started goin so slow it would take ages to do anything then the memory card was unrecognised a few days later.
Im guessing there is no way to repair these?

If you can't read it, you can't do anything...
R.I.P.... :|
Cheers

Gutted oh well

not as gutted as i am ... looks like i'll have to buy a new phone!

Just try to format it by these criteria
FAT32, 512 Bytes 4KB clusters
then let us know.

dude dont panic try to recover the card first before you format it. i am sure there are some imp data there eh?
use a disk recovery utility on ur pc
my best choice is Recover My Files http://www.recovermyfiles.com/
if you are using windows os also try to run scan disk
use pocket mechanic then on ur ppc
let us know how well u do

Sorry for posting...Wrong thread...

Froyo A2SD+ SD card corruption

Tons of new ROMs coming out now based on OTA and adding A2SD+. But one big issue. Quite a number of people have reported problems with corruption of their SD cards when setting the Desire into Disk mode and connecting it to a PC. I've read it the first time here
http://forum.xda-developers.com/showpost.php?p=7463184&postcount=348
and I can confirm it is reproducible.
Regardless if connecting to Windows or Linux, the card gets corrupted. It does not matter if you properly eject the drive. The Desire will respond saying the SD card is Read Only, and the only thing that one can do is to repartition it to fix the card.
I don't know what A2SD+ application everyone uses in their ROMs but I expect it's all based on some common version like the one put in from ieftm. As this is a serious issue it would be great if all you ROM cooks could look into it and try to fix it. Alternatively it may be a good idea to produce non-deodexed versions that save a significant amount of memory when installed normally without A2SD+.
Thanks for considering

I have this problem aswell its a bit of a nightmare there are a few files on my sd card that I can't even delete using andexplorer or my pc. I think the only way would be to remove my card and format it. I have never had this problem before only when I started using the 2.2 rom.

Noticed it before, i took the SD card out and put it into a cardreader, couldnt do anything in windows, said it was read only. Access via USB cable worked though.
Not that much of a issue for me, I mainly transfer files via Wi-Fi anyway, but I guess thats the explanation for the read-only behaviour.

Happened to me today, however I restarted the phone and everything seems okay now... :/
edit: nope, connected the phone again, chose "charge only" and then disconnected. The notification about my card being corrupted occured again, tapped on it and it went away... Dont know what to think..

I have the same problem .. And now it seems like the SD card is totally corrupted. Its not even possible to do a format

Okay thats it... Doing the titanium backup, nand backup and flashing some rom w/o A2SD+... :/

Out of curiosity guys, did the corruption of the SD card occur to the stock SD card that came with the Desire? I had the same problem with the stock card..
It seemed to unmount 3 or 3 times over a week and the next thing I knew it totally died and could not even be reformatted.. Happened on stock 2.1 that came with my Desire.. after I swapped to me own class 6 8gb Transcend I never had the proble again.. Just gonna upgrade to 2.2 now.. *fingers crossed*
Oh and yes.. I use A2SD+ on Modaco's 3.1. But that was after that card got corrupted..

I'm using card that came with the phone.
I'm going to try another Froyo Rom, just OTA rom rooted and we'll see.
Edit: I made my ext3 partition with ROM manager, if it makes any difference...

God dammit!
http://forum.xda-developers.com/showthread.php?t=747480

Yes its the card that came with the phone .. but it happen after i created the 512MB EXT3 Partition ... and I'm running this ROM : http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=741775&highlight=official it doesnt even use A2SD+

I dual boot my pc with windows 7 & ubuntu.... windows 7 scan and fix has repaired mine numerous times

I have class6 A-DATA 8GB and no problem. But with my last G1 i haved same card and with swapping goes to hell... I now correctly unmounting and disconnecting mobile from PC, after i save from PC to card. Flash have problems with writing.

This looks like a serious problem - it happened to me twice already. Devs, please have a look at this!

I have also had similar experience, SD card corrupt, yes it was the original card that came with the phone, EXT2 partitioned and using APSD+
Now why this happend is a mystery, but something I noticed when I tried the SD card in the PC - it was recognized, but said it must be formated, so I tried but it only saw it as a 32mb capacity!!! (it still would not format though - failed format..and since is no longer reconized at all..)
But, this made me think it "MAY" be something to do with the fact that when I did the Ext2 partition I seem to remember it also created a 32mb swap partition, or using Ext2 instead of Ext3. I have since learnt that it is advisable NOT to created a swap partition, so with my new SD card, after more reading about Ext partitions etc, I have only created only the Ext3 partion as I understand this is better than Ext2 and is less prone to corruption, and no swap partition and have had no problem since!
See this excellent post :- http://forum.xda-developers.com/showpost.php?p=7458565&postcount=8
It would be interesting to have some input from one or two of the developers with knowledge in this field to get an idea why this happens, and how it can be prevented.
It is also possible the the SD card was going to become corrupt anyway... with or without the help of Ext? / APSD+ - it does happen!

my sd was corrupt using a 512MB ext3 partition without swap partition in SD card :/

Try in windows: start > run > chkdsk x: /f
where x = desire drive letter.
I believe i did this in recovery mode > mount usb.

That's what happens when you don't want to use Froyos own A2SD implementetion because "widgetz doesnt workzz on dat."
Apps are not meant to be on an external EXT partition.
Wait until ROMs like CM have built in A2SD+, these hacky shell scripts can cause serious problems for the SD card.

Windows can not access EXTx partitions. As such is unfortunately not possible that it could possibly repair a broken SD-ext partition A2SD+ uses.

I can confirm the corruption without any APSD+ ROM
I had a Stock Orange FR 2.1 ROM, and the 4Gb card that came with the phone get corrupted definitively (recognized as a 32mb capacity too, it has something to do with the Cylinder-head-sector combination).
Anyway, I'm going to try APSD+ with a class 2 PNY 16Gb, and tell you then if I get a corrupted card.
FYI, the Sandisk warranty is applicable for the original card: replaced in 5 days

I got some problems too with corruped files on my SDcard and had to format it. I'm thinking that from now i'll only mount my card to pc in recoverymode... maybe that is safe to do?

[Q] My 16gb card shows as 1gb after a crash in a middle of partitioning with gparted

Hello,
My rom(iNsertCoin) has crashed today for an unknown reason, and entered nonstop bootloops.
I have tried to reflash the iNsertcoin zip but it didnt work for some reason, also it told me it cant mount the sd-ext (I am using ra-desire 2.0.0).
I have turned the phone off, and when I returned home I put my A-Data 16gb Class 10 Microsd (which was bought from newegg, so it cant be fake) in my card reader, and I started to partition the card like this: 1gb ext4, 300mb ext4, 100mb linux-swap, rest to fat32.
all of a sudden the program just crashed and from that point it tells me the card has 1gb unallocated space, in windows 7 it keeps asking me to format the card but it never succeeds, and it says the card uses raw file system.
I have tried chkdsk, and it told me its not available for raw filesystems.
I have also tried a number of programs, the HP partition tool, SDFormatter, nothing really helped.
Also, I tried using diskpart -> clean all command on the card but it keeps giving me weird error messages but usually it tells me its not ready, and it looks like the card is not responsive, although the pc recongized it.
I have tried doing this from a number of computers, another W7 computer and a XP computer. nothing worked.
I cant allocate space in gparted, and it tells me to create a partition table, and when I try that, the program just hangs.
Oh yeah, and I tried to put the microsd card into an adapter and put it in my dad's dslr and tried to format it, but there was an error.
Have I killed my microsd card? :/

Are you using gparted through an ubuntu livecd? Maybe try using the disk utility (system > administration > disk utility) to format the card with a new MBR scheme.

I am having the exact problem. Have you come up with any solutions?

Well, no.
I have sent the card to a-data for repair service and they have sent me a new card.
Anyway, slow speeds in almost any data2sd / data2ext roms still occur, so last week i have given up and got me an iPhone 4 from my carrier.

Yeah, I couldn't believe I did that either, but I was really fed up messing around with the desire.

the same thing happend to me once, after trying to get it going(formated on sunday and needed the card) it all went straight to hell until i tried it in another cardreader on my mac and the card is still working with no problems=

[Q] Low Memory Issue

My girlfriend got the HTC Wildfire S for MetroPCS a couple of weeks ago. It is a nice phone except for one little problem: The internal memory is crap. She has exactly 5 apps installed, all are moved to SD, and she has 7.14 MB or internal memory free. It is running the stock 2.3 Rom rooted. I need some help figuring out what to do. Before you guys make suggestions let me list what I have already done:
1. S-OFF and rooted, removed all bloatware, which moved it from 3.21 MB to 8 MB which seems like BS because a few of those apps were about 6 MB in size.
2. Moved apps to SD card partially in the applications menu in settings.
3. Cleaned caches
4. Uninstalled almost every application.
This is very frustrating because she cant update apps, she cant download apps, and it is frustrating because I have the old Huawei Ascend on CM7 and I have more apps and am faster than her phone, its ridiculous, I also wonder why after removing over 60MB or crap and bloatware it freed up about 7MB. Makes no sense. I don't want to do DT's app2sd script yet because she doesn't have a way to back up her stuff before the partition of the SD card. If anyone can explain another way or something I can do to fix this please..... It would be greatly appreciated.

Use Partition Wizard Home (Free) to resize your FAT32 partition and create your Ext(whatever your kernel supports) partition on a windows machine.
No need to back up. Doesn't destroy partitions.
My preference is Link2SD free from the market.
You can mass move your apps, dalvik cache and library files to the Ext(Probably Ext2 with stock rom kernel) from the SD card and internal to your Ext partition very easy.
Also you can set it up to auto do this when new apps are installed and choose which apps you want to keep fully internal for faster booting, startup, etc.

Is this the same question from two different people or one person logged on as two different people?
If your card is corrupt and can't be read try a program like Recuva on the PC (free) to get your files from it.

Format it in windows using the partition software I mentioned and make sure it is:
1/ Fat32
2/ A Primary not a Logical partition
3/ Make it the Active partition

thanks I have been working on it and got it to see the sd card
what about the 2 partion should it be ext2 ext 3 or fad 32 I guss it dose not matter I have tried all 3 but link2sd will not see the 2 partion
---------- Post added at 09:17 PM ---------- Previous post was at 09:02 PM ----------
the phone will see the sd card I have tryed fad 32,ext2 ,ext 3 and ext4 that app will see none of them as the second partion are you shure I dont need root or some thing? sorry for all the nob questions

Choose EXT3

Sorry for the double post but you have to be rooted from what I understand. There is also a script or application that you have to use to move the apps and you MUST be rooted.

It's no problem good luck!

SD card (too) slow?

Hello,
I compare my results with Antutu benchmark with other I found here and on the Internet.
My overall score is above 5300, but my concern is low read/write speed of my SD card:
(screen in attachement)
I have 32 GB SanDisk Ultra Class 10 with up to 30 MB/s read/write card. I know I wouldnt achieve such speed in practice, but I believe 5.6 MB/s write and 8 MB/s read is far too slow for that card and that phone.
I have second partiotion (for Link2SD) formatted with ext2 (2GB), the rest ("regular") partition is FAT32 (~30GB)
I am using Xperia Ultimate HD 2.0.3, stock kernel (locked BL)
Any suggestions?

sorry for that - it worked on my desktop. now file was moved to attachements

the read is slow, im gonna try antutu om my device, but cant install now. It says it dont have memory, but i have over half empty
edit:
What class is that sd-card?

It is class 10 card, 32GB, with up to 30 MB/s read/write (as declared by SanDisk

Yes, up to 30 MB/s. It means max that, but can be any speed lower from it
But Class 10 should be min 10 MB/s. Try formatting your SDcard, then check again.

It installed at least. Heres my results on stock sd card
If you got root try this:
Im not responsible for any harm that may happen, but this should be safe
https://play.google.com/store/apps/details?id=de.mehrmann.sdbooster
Install that app, ir similar
Set it to 1024, apply (best one for me, try your self. Dont go over 8000. 1024, 2048 and 3072 is safe)
Retest your sd card with antutu.
This is what i got on 1024

Great, thank you guys,
I think I will try booth suggestions - card re-format and SD card booster.
What is the option to back up partitions on SD cards?
I mean "second" partition that is not usually visible under windows, as it is second and ext2..
Or backup with TB, copy files to hdd, format and than copy back, and use backup to restore?

try to browse the second partition with WinRAR. It shows everything. If not use EASEUS Partition manager

Are there any published benchmarks for SD cards? I want to buy a 32GB card for use with Link2SD (i.e. apps running directly off the card) as well as for documents/media files, so I want it to be fast.

The best is cwm recovery. X-Part is fine also.
Do backup.
Then just copy fat32 partition on PC.
Now format sd card. (in usb sd card reader)
Repartition it again.
Put data back on fat32 partition. (return card into phone)
Now boot your phone into recovery.
Restore sd-ext.
That's it.
Please, note that sd cards must be formatted with sd card formatter from sd card association and NOT from operating system.
Then use gparted bootable disc to add ext2 partition.
Make sure MiB alignment is on.
Now, performance will be ok.
For sure add higher value in sd booster then default is.
