hi,

commenting out that line gives a better result.  scsictl format still spits
out an error immediately:

sd2(esp0:0:2:0): esp0: timed out [ecb 0xf087a038 (flags 0x101, dleft 0, stat 0)$

but then it appeared to continue with the format operation.
I'm now back to the state where I can read and write the beginning of
the disk, but all the bad sectors from before are still there (oh well).
"scsictl reassign" doesn't seem to work either:

15 sparc5:~ # scsictl sd2 reassign 8566
/dev/rsd2c: SCSI command timed out
/dev/rsd2c: device is busy
/dev/rsd2c: Check Condition on CDB: 07 00 00 00 00 00
    SENSE KEY: Media Error
   INFO FIELD: 8544
     ASC/ASCQ: Unrecovered Read Error

and on the console:

sd2(esp0:0:2:0):  Check Condition on CDB: 0x08 00 21 00 80 00
    SENSE KEY:  Media Error
   INFO FIELD:  8544
     ASC/ASCQ:  Unrecovered Read Error


there are bunch of sectors in the 85xx range that have problems even after
several reassigns, so this disk looks like it's just too damaged to salvage.
