SD card suddenly unreadable/unwritable...?? - EVO 4G Q&A, Help & Troubleshooting

Does anyone have the problem where the phone is able to read and write to the SD card, but then all of the sudden, it's not able to?
I have an intermittent problem that happens at least once a day where the phone suddenly is unable to read the card. When I start up the camera app, it says that it has insufficient permissions to write to the card. When this happens, I am not able to play music from the card or view pictures/videos from the card.
Once I reset the phone, it is able to read and write to the card again... I have tried the 'SD card mounting' fix in the development forum, but it did not solve the issue.
Can anyone shed some light on this?
I've got a rooted stock froyo 2.2 odexed. i've tried the stock kernel, netarchy's kernel, and kingklick's kernel with all the same problem...
One thing I did do is backed up my apps with my backup pro, installed froyo, and restored some of the apps... now when i go into appbrain, it shows updates downloading, but they never progress... handcent, shazam....
Thanks in advance...

SD Card problem with all EVO Roms Help!!

SO I am having a problem with every EVO rom I flash. Here is what is happening.
- I will open Astro or EStrongs and click on the SD Card where I have my APP Apks stored and click on the folder and it will just close the program. So then I will reboot and try to install them again and it will install maybe 3 apps before it starts saying "App not Installed".
- I am also having the "File Permissions" problem on OMJ latest EVO Rom when I try and use the Camera.
I have the latest Sprint Software installed and everything else. Can anyone help me out and tell me whatr the problem can be? I thought this problem was fixed?
It might be a bad sd card
I had similar issues with the sd card that came with my phone. It would work for a little while and then all of a sudden I would get file permission errors. Sometimes it would even come up saying the data was corrupt and needed to be formatted. I tried formatting several times both in the phone and in the computer.
Nothing seemed to help the issue. I then went to the store and purchased a new 16GB SD card and have not had a problem since. On another note, I have since left the 8gb card in my computer and have not had any problems with it there.
Yeah, It was working working fine the all of a sudden it started having issues.

[Q] Certain apps force close when reading from sd card

I recently flashed the bonsai4all 3.0 EB13 rom from the stock DI18, and from the getgo I noticed issues with the camera.
More specifically, any time I loaded the camera application, it would proceed to "unexpectedly" force close on me and simply exit to the launcher again. I thought this may have been a problem with just the camera, however winamp proceeded to crash whenever reading my music from the sd card as well.
Thinking it may have been a problem with the rom installation, I cleared all data/cache, and proceeded to reflash the bonsai rom. The camera+winamp actually worked for a short time before relapsing into the behavior above.
I know this is SD card related because whenever I dismount/remove the sd card everything works fine, however as soon as the card becomes available the apps crash whenever accessing.
Has anyone else had this issue? Any help will be most appreciated!
UPDATE: Just attempted ROM Manager's "Fix Permissions" batch, no impact. Going to try a reformat next.
Backup and reformat SD card. Probably got corrupted. Let us know if it works for u.

[Q] "Unable to move" Apps to SD error message

Edit: My sd card is working again! I would advise anyone not to use the App Mybackup or Mybackup Pro because this is what caused my problems!
I recently rooted my Evo with
http://forum.xda-developers.com/showthread.php?t=838448
Anyway i backed up my apps and i started to attempt to restore them. While doing this all of a sudden my evo started saying that it had critical memory left and i had to power it down. So i restarted my Evo and noticed that all the apps installed on my phone but not SD card. So i proceded to remove them all because whenever i tried to move the apps to the SD with Apps2Sd or the phone application function itself i kept on getting "Unable to move application" or something along those lines.
Anyway im wonder is there anyway that i can fix this problem to enable me to store apps on my sd? I can connect the sd card to the computer and manage the files.
Also i have tried to format the sd card but i still have the same problem.
I am about to try a nandroid restore and see if that will help anything.
I also cannot install apps of the market because they fail when the try to install to my Sd. So any installation to my phone i need to unmount the sd card.
Any help would be appreciated, thanks!

[Q] major sd card issues

i have been having major issues with my evo. where to start, really...
i have virus rom 2.2 rooted, apps2sd, etc...
i've been having issues with my evo being recognized by my computer when plugged into the usb port. i never used to have issues and this is a seemingly random thing that has started to happen.
i wanted to load some music onto my sd card and popped it out of my evo to plug it into my computer. unfortunately, my power button has been sticking on the evo and for whatever reason i put the battery back in after taking out my sd card. the phone reset, then couldn't recognize any of my apps that had been stored on the sd card. i put the card back into my phone and reset again but it refuses to believe any of the apps are available. i've lost access to market, appbrain, etc., and cannot re-download. when i log into my google account to redownload appbrain it will not let me because the website says i still have it installed.
i hope i explained this well enough. i've never had any problem like this before. my phone has essentially become useless because i cannot access any programs on it. any suggestions how to recover? unfortunately my last nandroid backup was in december. i've used titanium and lookout to backup since, but both are now missing. if there's any way i can recover my data (pictures, web history, text history, call history, address book, etc...) and then do a wipe and repartition my sd card/get market back, i'm willing to do it, i just have no idea how. any help is appreciated.
bump in case anyone can help, thanks
So hold on...you can't access you SD card on your EVO but you can when you stick it into the computer...because if that's the case and you can see the files on your computer still, I would back up everything on you SD card and then format your card from the computer...I had this very problem a couple months ago...and I recommend to put apps that you want to access easily (browser, market, voice, mail, etc...) on your phone memory...that way you can still use them if it ever happens again...that's just my 2 cents...
But anyways I recommend formatting your card and reloading the files onto it...fixed it for me

the apps that were on my SD card are the only things that have gone missing from it. it is as though they never existed... i don't even know how the marketplace ever got saved onto my sd card, but it's gone.
The apps are on the SD ext.when you took out the SD and the phone rebooted,you apps weren't there......follow the post above you should he good.or you can pit the card in wipe everything and reflash the Rom.....

64 sd card suddenly corrupted? [Q]

I was trying out cm7 and lighntingdude's kernel when I noticed after a reboot all my music was gone. I've tried formatting it in cwm,but it doesn't read the mp3 files even after I try it a couple times. Root explorers on my phone won't read it either but my pc does fine. I'm going to try with another rom but does anyone else have any thoughts on this?
edit- wiped again seems to have taken and fixed it. Mod can remove this if they want to.
