[AusNOG] SCSI hdd repair companies

[Elliott Willink]

Drive repair (as opposed to data recovery) can be a messy business - Unless you want to send them all the drives in the array (or you want to recover raw data, write it back to a drive and then trick the array into thinking it is the same disk) you would need to online one of the drives, after it is repaired, for long enough to recover the data you need.

(Without knowing the situation, as maybe neither of the drives spin up) being a 15 year old Sun system I would recommend speaking to a file system specialist first to see if there was an option of pulling the working data from the array by onlining the better of the two drives. I know with ZFS (which being 15 years old you probably wouldn't be running) you can pull a surprising amount of data with very sick drives - I would be sending the individual drives for recovery as a last resort.

Regards,

Elliott

Hi AusNOG,
 
We have two failed 36GB SCSI drives in a RAID10 array in a 15 year old Sun disk unit that we need to get repaired as they have critical data on them.
 
d0b0t4d0  RAID 1 (Mirrored) DPT      RAID-1            34732MB   Unknown 4:0
  d0b0t3d0 Disk Drive (DASD) SEAGATE  ST336704LSUN36G   34732MB   Failed Drive
  d0b0t5d0 Disk Drive (DASD) SEAGATE  ST336605LSUN36G   34732MB   Failed Drive
 
Wondering if anyone on the list has experience in repairs to very old SCSI disks, and if anyone has any recommended repairers.
 
Many thanks,


Greg
