Hi,
I have an optical disk where the data needs to be recovered. However,
the drive tells me:
SCSI device sda: hdwr sector= 512 bytes. Sectors= 450566 [220 MB] [0.2 GB]
sda:scsi0: MEDIUM ERROR on channel 0, id 4, lun 0, CDB: Read (10) 00 00 00 00 00
00 00 02 00
[valid=0] Info fld=0x0, Current sd08:00: sense key Medium Error
Additional sense indicates Defect list not found
scsidisk I/O error: dev 08:00, sector 0
unable to read partition table
So, as far as I can tell, the drive is having trouble reading the
defect list.
I'd like to bypass the defect list, and read whatever data is left of
the data-area. If the defect list is a goner, I'll have to puzzle
everything back together again myself....
Reading the SCSI spec, I found "read long", which I hoped might give
me the uncorrected raw data. However, that command is rejected with
"Illegal request".
Is there anything else that I could try?
The drive is:
scsi singledevice 0 0 4 0
Vendor: IOMEGA Model: BETA230 Rev: 2.02
Type: Direct-Access ANSI SCSI revision: 02
Detected scsi removable disk sda at scsi0, channel 0, id 4, lun 0
Thanks in advance,
Roger.
