You can change the retries. Personnally I do the following with any
new SCSI drivers I buy:
1. set the retries for read (read recovery parameter pages) to zero
2. exercize the drive (in its final position if possible, not lying on
the desk) for one day
3. put back reasonable values for retries (usually one)
4. put verify retries to none
When you get any problem with a drive, you verify it (some PC
BIOSes have this option, e.g. Tekram, Qlogic, Adaptec).
NB: your problem could also be that ARRE/AWRE is set (auto-replace)
and this can take a lot of time on some drives.

formatting is dangerous if you do not keep the growth defect list.
