That said, I'd much rather resolve the checksum/validation issue.
l have this, on a one the old amiga 2000 scsi drive l think u have to use quater back tools or disc salve to fix the files and tranfer them to another drive partion.
and then re format the drive .
l dont know l have really only used 1200s with ide
with them u hold down the 2 mouse buttons and boot with no startup seqwence is one way geting them to vaildate.
but think checksum means drive file damage.
this drive is old but think on newer drive its when its wrting to the drive and it gets stoped or the machine crashs cuases these problems.
good luck dude let me know how u fix it.
