SD Card Damage. Phone stuck on bootscreen

Connected my USB to my phone to do an update. Computer said there was aproblem reading my SD Card, so I unmounted and got a notification in the Notification bar stating SD Card Damage. When I clicked on it, it gave me only one option REFORMAT SD CARD....hit home went to setting, SD Card and it showed no space available, but there was still 52MB of Memory on the phone.
only option higlighted was Format SD Card. Tried plugging SD Card in my card reader and got same error. So I said screw it. I formatted the SD Card from the selection on the G1 and now when i reboot it stays stuck in the first boot screen. It won't do anything else.
I had JFv1.5 ADP A2SD on the phone.
Thinking I may have to buy a new SD Card and then a nandroid recovery.
Any other suggestions before I do that.

I had the same problem...
was sure i needed a new SD card, but i ended up downloading a sd formatting tool (i think it was from panasonics website)... and that got the card back working, no other attempts at low level formatting, re-formatting, any tries to delete partitions, nothing...
the only thing that finally worked was this SD card formatting tool...
you'll sadly probbaly need to reflash your phone, which i also had to do...
but, I did end up with the 1.5 update....

I have a samsung epic on android 2.1. I used to have the sd card damaged problem. I had to backup everyday for fear of losing information. I saw on one forum a note about upgrading to a Class 4 sd card. I went to frys and they only had class 10 in 16gb (about $40). I purchased and I have not had this problem since!!!
Problem: SD Card error
Problem Solved: Trash the Class 2 sd card that came with the phone and get class 4 or higher.
Woohoo!

SD Card Corruption

I'm trying to troubleshoot an SD card issue, and I don't know if it's the card or the device. I am using a 16GB SD card in my SGS4G, and occasionally when I restart the phone, or more specifically, when it crashes, the SD card gets corrupted. It has now happened three different times, and each time I re-format the card and copy over my last backup. Has anyone else experienced this?
My next step is to fall back to the original 8GB card to see if the problem continues.

[Resolved] Card won't mount

So I'm fairly new to android phones and my GNex doesn't have an SD card so I don't know what to do. My friends HTC Desire HD keeps saying the SD card is unmounted and when he goes to mount it in settings, it keeps saying it is safe to remove it. What can I do? I tried putting in another sd card and it worked but this one won't. Thanks in advance.
Edit: I put the sd card into my computer and saw that all the files were still there. I put it back in the phone and now they've showed up. Why did this happen and how can I avoid it in the future?

reformat
did you try to reformat sd card

[Q] micro sd locked??

hey, is the sd locked for been read only by the phone?
if I put the sd on a usb card reader I can't read it, the pc says to format it...
if I format from the pc with the sd in the phone on mass storage the phone says that file system is wrong...
is it normal? any solutions?

Try unmounting it in the phone go to settings and storage. Then try erase SD card and see what happens.

did it yet, it just format the sd and is locked again...
is a kingston 8gb class4, it was on the phone when I bought it...
I think the file system thing could be the problem...

I had problems with the SD card on my phone. It was actually causing the screen to freeze in stand by even pulling the battery and restarting wouldn't get the phone to work. Tried re-rom'ing the phone going back to factory rom nothing working. Left for a few minutes and screen would freeze.
New SD card and sorted all my issues out!

SD card issue after restart.

If i restart my phone, i always have to reinster the SD card, otherwise the phone can't see it.
Any suggestions for that?
