SCSI Medium Error (capacity): recoverable? |
|
|
I have a drive that was working fine until a recent reboot. Now, when
the box trys to boot, the scsi controller gives me a "medium error".
Digging further (with linux and scu) I find that the sense key is 0x3
and that it fails specifically when reading the capacity.
Other drives on the bus work fine, and other drive details like model
number, head count, and cylinder count are ready correctly from the
problem drive.
The scu utility looks promising but cryptic. Maybe even the "set
device capacity" command if I could figure out what units it expects
(blocks?! sectors?!)
Is it possible for me to manually specify capacity to something like
dd or scu so I can read from the drive and get some data off it? Or
better yet, update the sense block of the drive (???) with the correct
capacity?
Any help appreciated, thanks. |

I have the same problem with my ST336607LW. All advice are reduced to
two decisions: check cabel/terminators and to throw out a disk :cry: |

0x3 key is just "medium error".
Get the full sense data, incl. ASC and ASCQ.
After that you can look them up here: http://www.t10.org/lists/2asc.htm

Hmm.

If the drive can't read it's capacity, it can't read anything, hence the 'Hmm'.

It doesn't work that way.
