How do you tell if a flash drive is just dead?

#1 Post by Rickajho » 26 Mar 2014, 12:39

There seem to be a lot of posts here about all types of drives that have gone RAW and nothing can be detected. How do you know when it's just time to give it up because the drive is defective and no amount of diagnostics is going to get at anything? I had two flash drives crapped out when the power supply to the hub they were connected to flaked out. One of them I recovered. The other one? History of what I tried and the TD log are below:

What I tried:

Windows reports used space, free space and capacity all as zero bytes.

Windows error checking does nothing.

chkdsk /f reports:

The type of the file system is RAW.
CHKDSK is not available for RAW drives.

TestDisk (TD) identifies the drive correctly:

Disk /dev/sdh - 1998 MB / 1906 MiB - SanDisk U3 Cruzer Micro

Select drive, TD does not identify the partition type. Select Intel/PC partition. TD reports:

Disk /dev/sdh - 1998 MB / 1906 MiB - SanDisk U3 Cruzer Micro
CHS 243 255 63 - sector size=512

Select Alanyse. TD reports:

No partition is bootable

Selete Quick Search. TD analyses 243 cylinders. TD reports nothing & gives the options:

Keys A: add partition, L: load backup, Enter: to continue. Select Enter reports:

No partition found or selected for recovery

Select Deeper Search. TD analyses 243 cylinders. TD reports nothing & gives the options:

Keys A: add partition, L: load backup, Enter: to continue. Select Enter reports:

No partition found or selected for recovery

The only option is Quit which returns to the main menu. At the point the only working options you can perform on this drive are to either change the disk geometry or to write a new MBR to the drive.

Select the drive again, but change the partition type to None. Quick search now takes a very long time. End result is the same:

No partition found or selected for recovery

Quit...

The TD log for what I tried:
