How to fix sector 0 of a USB flash?

[hack3rcon]

Hello,
I have a USB Flash drive and when I plugged it to my PC then nothing mounted and "dmesg" show me:

Code: Select all

[  305.076160] print_req_error: I/O error, dev sdc, sector 0
[  305.076168] Buffer I/O error on dev sdc, logical block 0, async page read
[  305.076187]  sdc: unable to read partition table
...
[  307.104342] print_req_error: I/O error, dev sdc, sector 15124864
[  307.104351] Buffer I/O error on dev sdc, logical block 1890608, async page read


I tried to use "hdparm" to fix this problem:

Code: Select all

$ sudo hdparm -I /dev/sdc

/dev/sdc:
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

ATA device, with non-removable media
Standards:
   Likely used: 1
Configuration:
   Logical      max   current
   cylinders   0   0
   heads      0   0
   sectors/track   0   0
   --
   Logical/Physical Sector size:           512 bytes
   device size with M = 1024*1024:           0 MBytes
   device size with M = 1000*1000:           0 MBytes
   cache/buffer size  = unknown
Capabilities:
   IORDY not likely
   Cannot perform double-word IO

I read sector 0 with "hdparm":

Code: Select all

$ sudo hdparm --read-sector 0 /dev/sdc

/dev/sdc:
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

And used "--repair-sector" and "--write-sector" parameters to fix this problem:

Code: Select all

$ sudo hdparm --repair-sector 0 --yes-i-know-what-i-am-doing /dev/sdc

/dev/sdc:
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
re-writing sector 0: SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
succeeded


And:

Code: Select all


$ sudo hdparm --write-sector 0 --yes-i-know-what-i-am-doing /dev/sdc

/dev/sdc:
SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
re-writing sector 0: SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
succeeded


But problem not solved and I can see my Flash drive:

Code: Select all

$ sudo cfdisk /dev/sdc
cfdisk: cannot open /dev/sdc: Input/output error


Any idea to solve it?

Thank you.

[p.H]

I'm afraid that the flash drive is dead.
Can you read other sectors ?
What does dmesg say after plugging the drive ?

This output is not complete. Initial messages are missing.

[pendrachken]

Can you read other sectors ?

Well, since the controller thinks the drive size is zero bytes long, and that there are no addressable areas of storage memory at all I'm gonna go out an a limb and say NO.

How do you know ? From hdparm's output ? I doubt it is relevant. A perfectly working USB flash drive gives me similar output. I think that it just does not support the ATA commands hdparm uses.

And I can read other sectors. For example:

Code: Select all

$ sudo hdparm --read-sector 400 /dev/sdc

/dev/sdc:

[p.H]

Looks like a USB issue.

And I can read other sectors

Not with this command. It is the same output as with sector 0.
hdparm does not work with a USB flash drive.

Which tool is OK for USB?

[p.H]

Any tool which works with all types of block devices, such as dd and its clones (ddrescue...).
You can pipe the output to hd (hexdump) to print it in hexadecimal+ASCII.
But the USB reset messages and errors in the kernel log lead me to conclude that it will fail too.

Did you try to plug the USB drive to other USB ports, other computers ?

I plugged it to other computers and I got the same result.

[p.H]

Then a selective incompatibility with the computer is unlikely (unless all computers were the same model).
I'm afraid the flash drive has reached the end of its useful life.
