About two weeks ago my SDcard kept coming up as damaged/corrupted in my e4gt and in my evo 4g so I figured I was sol and formatted it. Now there's nothing saved to it except the normal stuff that's saved when formatted via android. But now I was trying to move a large file to the SD card both rom toolbox and root browser freeze after about 300ish MB and my phone restarts. I tried just straight moving the file, copying it and zipping it and no matter what it locks up and restarts. I tried just redownloading the file onto the SD card directly with the same end result it locks up and restarts. Anyone know what could be causing this?

Maybe you SD card is damaged or corrupted still? If it is trying to write to a corrupted sector that would explain the crashes, and a mere format isn't going to fix corrupted sectors.
As to how to fix our even test for corrupted sectors on a ssd I am at a loss.

Have you tried checking it on your computer with Scandisk? Might find something, though I had a card that was giving me random problems (disappearing apps, phone saying card was damaged) even after Scandisk said it was okay, no problems after using a new card.
Be careful about ever letting Scandisk RESTORE damaged files because you will likely end up with a bunch of useless CHK files (been there...).

anyway to solve it?

SD card unmounted without you doing anything? What did you do before you encounter such problem? I experience it before.. when after flashing a ROM.. and it occurs.
But as I know flashing ROM can corrupt the SD card. So you may consider to format it.(of course save all the necessary files in it first)
a failing sd card will also cause this, i had a 16gb give up the ghost last week, only realised when i took the card out and put it directly into my computer and it kept un mounting.
It doesn't have to be a bad SD-card though. Android is pretty picky, so even some bad files or something similar might be the cause.
I had the same problem and for me (not everyone though) reforming the card on the pc fixed it.
im using the ota rom as i have not root it.. it failed 5 times in a row today... after restarting the 6th time it worked...

Sometime yesterday my epic stopped seeing the media on my sd card. The data is on the card, but my phone just won't read it. Any ideas?

Did you try popping it in and out? Happened to me once.
Sure did. I did it several times with no luck.
I have always been suspicious of the shutdown + battery pull technique (leaving it out for at least a solid minute) and yet oddly, it seems to work for things like this sometimes. It certainly can't hurt. And if you see the media scanning process begin on start up, you may be good. Maybe try that?
You mayb have to reformat your SD card. Backup your sd to a computer. Go to settings/sd card and phone settings/unmount sd than reformat. Than restore your backup. Reformatting usually fixes SD card issues.

Before you reformat, make sure you don't have a file with a name that has a "period" at the beginning like ".nomedia" at the root of your sd card. Folders are fine, but a .nomedia file stops that section from being scanned, so if its placed on the root of the sd, nothing gets scanned

So i was preparing to transfer a rom from my pc to my sd card. I mounted my sd card to the pc like normal. For some unknown reason, I pulled the usb cable out of my phone without unmounting first. I then closed everything out and remounted my sd card to the pc. When I attempted to copy over the rom zip, it was just extremely slow, like 1+ hrs to go slow. I cancelled the operation with some difficulty. When I again remounted my sd card, the pc wanted to run a check and fix on it. Reluctantly, I did it and it finished without finding any errors on the sd card file system. So I tried again with the same results. I can, however, transfer files from the sd card to the pc with no issues. What the heck? Any help would be appreciated.
Copy your SD card to your computer to back it up, and format the SD card FAT32, then copy the contents back to the card.

That's what I figured. Just wanted to check for options before I did that. Do I need to remove the sd card from the phone, or can I just do it through the mount? It's one thing I haven't had to do before.
If you have a USB card reader that'd be ideal, but if not you can do it when mounted via USB.

Backup and format complete.
Currently restoring my sd card files. Going VERY slow, just like when I was trying to copy a zip file over originally. Transfer speed started at 1.5 mb/s and has steadily dropped dowm to 176 kb/s (not a mis-type). Now is working it's way back up. Any idea why it would do this? Never had this issue before. Frustrating.
No idea. Maybe try another SD card if you can, maybe try it on another computer to see if that makes a difference...? Are you using the HTC Incredible USB cable or aftermarket?

It's the htc cable. The transfer rate did go back up to 1.5mb/s eventually. What is odd is that it transfered just fine from the sd card to the pc. Seems like it's working though. Around 2hrs or so for 6.45 gig from pc to sd card. Sound reasonable?
To be honest: I'm not sure if that's good or bad, I'd have to give it a try and let you know.
Yeh, I've always claimed to be only partially retarded. :-D Never actually thought about that option. All is good now. Things seem to be working as planned. Thanks for all the input.

While its transferring slowly, click the "details" arrow in the transfer window so that you can see what exactly is happening. Transferring a ton of tiny files (i.e. cache) slow the transfer rate down considerably.
This happened to me when Zedge had a cache leak... It transferred slowly when it got to the app's cache folder, the eta climbed up to like a hour for 2 gigs! WTF! After looking at the details i fount that there were thousands of tiny files in Zedge's cache folder that just bogged down everything as the computer recognized each and every one of them. I deleted the folder completely and all was well again.
2+ hours is a long time for 6 gigs via a USB 2.0 wire, it should be like 10-15 minutes.
My external sd cart (named extSdCard) on my sgs3 747 Lh9 dissapeared after backing up with rom manager and then pushing a file over from my computer to my phone. I tried putting it in another android phone and it called it a blank sd card and it wouldn't even open! Please help me figure out how to fix this, I have alot of important stuff on my external sd.
Seems like it got corrupted. You can try out some of the file recovery apps from the market but I've never used any so I can't vouch for them.

Don't format your sd card yet. This happened to me several times. It's the phone itself. The card doesn’t stay locked properly. You'll notice faster battery drain for a few days if it's like anything that happened to me. Back up your sd card if possible. Reinsert the card while the phone is off. I push the metal guard in a little so it stays in. Turn it back on. It should work. You can follow what I did at your own risk.

Similar thing happened to me a few days ago. Notification bar said that the card was damaged. I simply put it into my PC card reader and ran Mini Tool Partition wizard (Google the free download) and I did a scan and fix and I did lose some files from a recent folder transfer (which is what I think caused the problem) but the card file system was quickly repaired and no reformatting was necessary. In other words, the card did not have physical damage.
ok, this is a very strange problem. im having an issue where anything i put on the external sd card gets deleted after a reboot. its a 64gb card and i have 15.8 gb left on it. anything i download or transfer to it transfers fine and i dont get an error, yet after a reboot, there is no trace of the file.
i first started noticing this after attempting to make a nandroid. TWRP would say it created it successfully so i just reboot system. and once the OS is loaded, if i look in any file explorer, its gone. and going back into recovery shows its gone. Same with anything i download through the browser. nothing stays saved and i always end back up with 15.8gb left on my card. even when i transfer something from the PC to the card...after a reboot, its gone again.
i put a different sdcard in my note and transferred a rom to it and rebooted and it seems to have remained on this 32gb card so i know my phone isnt deleting anything.
after putting the 64gb card into another phone and attempting to transfer a file to it, it fails halfway through the transfer every time. though i've not got an error saying my sd is damaged so idk what to think.
could my sdcard just have went bad and im just not getting a "damaged" error?
im in the process of transferring the 15.8gb of readable data off the 64gb card to a pc, yet its been "calculating the time required to copy the files" for 2+ hours now.
any help or ideas would be great. i really dont know what to do short of formatting it but i have a lot of files i need to save before i do that. :/
after searching numerous threads similar to this problem, i haven't found anything useful explaining what could be going on..
I had the EXACT same situation. ...I had a sandisk ultra...I contacted sandisk and they said it was something failing on the card. I had to send mine in last week so now im waitjng for a replacement. You're gonna have to get it replaced
