Can nand restore corrupt sd card - EVO 4G Q&A, Help & Troubleshooting

I performed a nand restore on my Evo this morning. Everything seemed to be going fine. The restore completed and I booted up the phone. I went to change the wallpaper and it couldn't find any. So I mounted the sd card as a disk drive and started looking. I found that everything in the dcim folder, wallpaper folder, and the video folder were gone. The folders were still there but all of the files in them were gone. They were there before the nandroid restore. I tested the card and no error were found. I am not using apps2sd and don't have any ext partitions. The card is formatted fat32. If the restore didn't cause it, any ideas what else might have? I thought the card had corrupted but the tests were good, it is a new card, it is a brand name card, and it has been working fine for a month now.

SD card mounted read-only?

I had a situation arise recently after my Froyo 3.26.651.6 (Rooted) update... Several full nandroid backups and titanium backups later, and then deleting some of those big files, the SD card started mounting read-only a few hours after I was done and fully updated/rooted.
So what happened was I copied everything off (finally), formatted it with FAT32 (non-quick), threw it back in the phone, copied everything back on the card (minus internet cache files, etc) and it is all working great since.
My question is this - is there a better format for the EVO than to use Fat32? Obviously it reads it, but should I have used the phone itself to format the card? What format would have have produced?
Thanks!

Leedroid 2.2d and corrupted sd card

Hey guys,
I was going through the process of installing the new leedroid rom by T-mod 2.2d.
I did a back up from nandroid and did a full wipe.
I went to install from zip and i couldnt find any of my ROMs i had copied onto my sd card? i am 100% confident i placed them in there.
Just today i partitioned my sd card properly with two primary partions of fat32 and ext3. Fat 32 has 29gb free and ext 3 has 512. Could there be a problem here? i just followed the instructions provided and everything looked sweet.
Before i had partitioned i copied all my files onto my HD then i proceeded using Gparted. Since everything was wiped off my SD card i just cut all the backup files from my HD back to the SD. It took up too much space on my pc!
All i have done is factory wiped and clear dalvik and then i rebooted (since none of the ROMs were listed in 'install zip from sd card'. It was then stuck on the leedroid startup page and goes on a loop.
I then performed a restore from nandroid. It now boots up fine, but now my SD card seems to be corrupted! all the files in there are shown with symbols etc. I can add new files into the sd card though and they dont appear to have weird symbols. I clicked on the disk and clicked on the diagnostic button which i also selected to fix automatically issues. Now my whole SD is wiped. and there are no files in there anymore... i put a few mp3s within and the music players dont detect any mp3 music.
Anyone have a take on what i can do? argh! i am still on 2.2b after the restore but my sd card has no files etc.
please someone help me, i will be very grateful!

it may just be a corrupt sd card, it happens sometimes you should return it and get it replaced
It was working 100% fine for a long time mate.
Should i go back into Gparted and delete my ext3 partition? I want to format my sd card, but im really confused atm.
My phone is working etc with all messages and phone history still here. It is running T-mod 2.2b. But all my apps which i had stored to my sd card are no longer functioning and i also wiped delvik from my phone.

your best bet isnt to just format it, but use gparted to delete both partitions on your sd card, then re-partition and try again
I just deleted both partitions and just created 1 partition as fat 32 will full memory using Gparted. I unmounted my phone and took the sd card out and put it back in, rebooted.
Connected it to my pc - but there are no folders in the SD card?
The phone isnt installing any software on the sd card when i boot it up?
I put mp3 files into the sd card but the phone doesnt read any music. Is it because im using a rooted desire? with T-mod 2.2b.
Literally all my files on my SD card are gone, no idea how to proceed
anyone??
I can still move apps (not the dalvik) to the sd card.
But my SD card has no folders in it. My phone wont install any on the SD card.
It says i have full memory out of full memory available. I formatted the sd card just then, since all my files are not there anyways.. still nothing happening
Help! running T-mod leedroid 2.2b! all internal apps etc are working fine.
What if i perfom an nandroid backup, store it to the sd card.
Then put the 2.2d rom and radio rom on and flash the two?
Will all the folders etc be stored back to my sd card?
Update: performed nandroid backup. Put 2.2d rom and radio rom on the sd card and again it does not appear on the zip list in recovery.
What is going on!

why not post here? if this turns out to be quite common you woudnt want to reply to xxx users would you ?
I have had the same issue twice now under LeeDroid 2.2a and 2.2b.
Right now I am using my Ubuntu laptop so I inserted the SD card into the laptop. It mounts the 7.5 gig Fat32 partition and lets me read what's on there, but it wont properly mount the ext3 partition. It shows as blank in the file browser (on the laptop) and wont let me copy to it or create any new files, so it seems corrupted in some way.
I knew I had a problem last night because my phone freezes on the white-background with green "HTC" lettering whilst booting. If I take the SD card out of the phone it boots ok, likewise if I replace the card with a different one, that's only formatted Fat32, that works ok.
I used the built in function of ROM manager to prepare the SD card, it created a 512mb ext3 partition at the end of the disk, not sure if that makes a difference. Has anyone had any success using proper apps like gparted to partition the card?
Really pi**ed off at this phone now. Dont want to wipe the card again just to have it work in my phone for another week.
[Solution]
I had a friend check out what was up with my SD card. Nandroids and zips were being stored onto the sd card but they weren't appearing on the fat32 side.
In fact, all the files were being stored to ext3! this was the root of the issue. I believe i partitioned incorrectly or what not by using Gparted. I have resulted in using Rom Manager (download off market) instead to set partition ~ much easier.
To fix the main issue with SD card: Go to phone settings -> SD & Phone Storage -> Unmount SD card --> Format SD Card.
Files should appear on your sd card again -> connect your phone to your USB and check that the files are back. That's your fix
Then just add your Roms, music, videos back onto your fat32 partition as before. Using Rom Manager, the Roms stored on SD appear again.
Edit: i have installed T-mod leedroid 2.2d and is working great.
To the previous post ~ i just did a full wipe because all my files on the SD card were corrupted anyways, could not even copy them. But i didn't think my SD card itself was corrupted.
Thanks,
Brendan
I did a little more investigating last night. On Ubuntu, if I insert the SD card, it mounts both partitions, but it can only read the fat32 one. I can see my images and stuff from there so I know its ok. But if I view the ext3 partition, it shows as empty, but if I right click on it, the properties show that there is 123mb in use of the 512mb partition. That seems about right because there should be some apps and stuff in there. I have made sure that the files arent hidden or anything, but still nothing.
If I try and copy anything to the partition, it wont let me and gives me a rather cryptic error: something along the lines that it cant access the card because it is not ready? I couldn't even unmount the disk because of the same error. I dont have my Ubuntu machine with me now so I cant check.
I can copy the stuff I want off my card and re-format/partition it but to be honest its more hassle than its worth.
I'd be more inclined to find out why this is happening. It only seems to go after the handset is rebooted (my battery went flat on Saturday) and since then, nothing.
I appreciate you posting your solution but I think we have slightly different problems..
Thanks

[Q] SD Card problem

I have a 32GB card installed in my A100. Have rooted the 100 and installed Crossix memory swap. Recently started having problems when trying to view photos in Gallery. I removed the card and inserted in laptop to view contents. I decided to backup the card to the laptop. While doing so I encountered several photos and a few files in Android/Data/com.amazon.venezia/cache that would not copy over to backup because they were corrupted. At this point should I reformat card and copy back the files I do have or should I just delete the corrupted files from the card and put it back in the tablet or is there another remedy to follow.
Thanks

I would backup what you can and format the card fat32 again. Sounds like its being unmounted or removed, if you use that swap you can not remove it while the system is powered on, you have to turn all the way off or you get corruption.

Just installed twrp for d852.. sdcard not showing up.. but backup went to sdcard...?

not sure what is going on but basically when i went to backup sdcard didn't show up only internal storage did with around 30gb (sdcard is 64gb) So my plan was to back it up to internal and manually move the files to sdcard for safe keeping, and then make a copy on my pc as well. However the strange thing is that during the backup it said it was backing up to/data/twrp/ or something along those lines, however after i rebooted phone and looked in sdcard directory/twrp/backup/ the backup was there... this makes no sense to me does anyone know what is going on?

i'm a complete idiot the reason which i already knew but forgot is that twrp needs fat32 file system and my 64gb sdcard was exfat. The backup actually went to internal storage in a folder called sdcard and i was just rushing and didn't realize it, if you have this issue just get a fat32 formatting tool and reformat your card to fat32. (windows wont format cards > 32gb to fat32)

Weird SD card Problem

My Note 4 has developed a bizzaro problem. Hope you guys can help. When first booted, all is ok. My files show up in the ext sd card directory just fine. But shortly afterwards, the entire ext sd directory is empty. No files show. However, in settings, storage shows the card and correct storage stats for it. The card is not corrupted. It plays fine in other devices. Any ideas here?
Nevermind. I gave up and did a factory reset. Fixed the problem. Not sure which naughty app was causing the problem
