Must I say goodbye to this Flash?

hack3rcon · 08-27-2016, 01:17 AM

Hello.
I have a Flash drive with below information :

Code:

Bus 003 Device 004: ID 090c:1000 Silicon Motion, Inc. - Taiwan (formerly Feiya Technology Corp.) 64MB QDI U2 DISK

I did below commands on Linux and you can see their result :

Code:

sudo mkfs.ext2 /dev/sdc
mke2fs 1.42.5 (29-Jul-2012)
/dev/sdc is entire device, not just one partition!
Proceed anyway? (y,n) y
/dev/sdc: Read-only file system while setting up superblock

Code:

sudo fsck -fy /dev/sdc
fsck from util-linux 2.20.1
e2fsck 1.42.5 (29-Jul-2012)
fsck.ext2: Read-only file system while trying to open /dev/sdc
Disk write-protected; use the -n option to do a read-only
check of the device.

Code:

sudo hdparm -r0 /dev/sdc

/dev/sdc:
 setting readonly to 0 (off)
 readonly      =  0 (off)

Code:

sudo dumpe2fs /dev/sdc
dumpe2fs 1.42.5 (29-Jul-2012)
dumpe2fs: Bad magic number in super-block while trying to open /dev/sdc
Couldn't find valid filesystem superblock.

How can I fix it?

One more before you throw it into the garbage bin.

Code:

dd if=/dev/zero of=/dev/sdc bs=516

Writing it raw might be able to break through.

dd: opening `/dev/sdc': Read-only file system

One thing that might work is to find a Windows computer and reformat the drive with Windows. I've rescued a couple micro SD cards this way for sure, and I think I've rescued a USB thumbdrive or two in the past. Basically, I wanted to format the SD cards to ext2, but no matter how many times I tried, I'd get that error when trying to mount the card a second time. And gparted couldn't deal with it. But I could reformat it on a Windows 7 computer.

Windows show same error

Oh well, it was worth a shot.
