YES , Scsisys 2.2 likes to kill virgins I have two drives that have
no responses to an adaptec scsi card in a pc " adaptec 2940 "
card bios reports no drives found after a scsisysfmt program from
scsisys 2.2 .The drives will spin up but thats all, no other
actions from drives can be done . The drives in question are
"Quantum Pro Drive LPS 105S" 105meg and " HP97560" 1.3gig
I believe the scsi information that is on drive has been erased by
scsisysfmt program and drives rendered useless for all future
uses .
Thanks ,
Boris
