You didn't write how old the drive is, but I know that at about 5 years these drives are at the end of their lifespan and to replace such if need be.
I see 20G hard disks of similar model for the 30 buck range on ebay. Sounds like a cheap fix.

I have an IBM SCSI Internal Hard Drive that I use on a MAC running OS 9. My computer can no longer read the hard drive. Whenever I boot up the computer it will crash if the hard drive is installed. When it is not installed it boots up fine. The hard drive came with an adapter that I think may be the cause of the problem. Is this a common problem that can be fixed by purchasing a new adapter? Below is all the information on the hard drive label:
Type: DGHS
COMP IEC-950
*ECE32284*
*PN59H7013*
SN 6810A623GK
EMC P/N 072-000-123
11S59H7013ZM1FV110A623 9808
Please let me know if you can help me with this situation. I've searched the IBM web site but it appears they no longer have a support section for hard drives on their site. Thanks for any help you can give me.
