Topic: MicroSD Card damaged

I have a MicroSD (16GB) which I cannot access anymore. I've tried to use GParted (from a Parted Magic Live USB Stick), DISKPART (windows 7), fdisk (ubuntu) even EaseUS software, but nothing seems to make regain access to the chip...

My last atempt with GParted gave me a gparted_details file (see below))

I don't know what else to do...

I'd appreciate some help...



GParted 0.17.0 --enable-libparted-dmraid --enable-online-resize

Libparted 2.3

Re: MicroSD Card damaged

My initial though is that MicroSD card is going bad.

If you are still running Parted Magic Live and haven't rebooted, then look in the system log for I/O errors from when you used GParted to try to create that FAT32 file system.

dmesg | less

If you have rebooted, and you don't care about the content of that MicroSD card, then try this destructive test on it:

sudo dd if=/dev/zero bs=1M of=/dev/sde1

Make sure that the MicroSD card is still device sde.  Use GParted to check.

Then look in the system log for I/O errors.

dmesg | less

Re: MicroSD Card damaged

Using dd to write to every sector on partition 1 of that MicroSD card worked.  (No I/O error from dd, just the full up message).

1. Capture new system log message as they occur, just in case any errors are reported.

dmesg -w -T -x

And press enter to put a blank line between old messages and any new messages.

2. Use GParted to create a FAT32 file system again on that MicroSD card again.
