this is really strange - I've got this 1TB Western Digital HDD and multiple machines (including an USB3-SATA Bridge) detect this HDD with only 32MB capacity.

I guess the Harddisk is broken and ripe for the trash, but before throwing it away - could this be just a firmware issue?

fdisk:

$  fdisk -l  /dev/sdf

Disk /dev/sdf: 33 MB, 33347072 bytes

Any Ideas?

Can you post any kernel messages that relate to the drive? –  David Schwartz Jan 21 at 12:23
    
@David: At the moment I only used it on a USB-Bridge.. nothing unusal here. It reports 32MB capacity. –  mt_ Jan 21 at 14:09

The drive just needs its capacity reset. You can use whatever tool you like to do it.

Most likely, the drive was part of a RAID array and the controller protected the area it was using.

Wow. Never heard of this before. Are there Linux tools for the job? I don't have any windows machine here. –  mt_ Jan 21 at 14:10
    
HDD at full capacity again! Thanks! It was indeed a HPA –  mt_ Jan 22 at 22:38
