IBM Ultrastar 146GB disk limited to 37GB

I have 4 IBM Ultrastar 146GB U320 SCSI HDD's which are limited to 37GB, they were replacements for 4 broken 36GB drives

I was wondering if it is possible to remove this limit and use the full 146GB

IBM part: 08K0322
Model: IC35L146UWDY10-0
Firmware: S25F
man.dates: Jun-2002 / Sep-2002

On the sticker it says: Capacity: 146 GB so my best guess they are 146GB drives with a 36GB firmware?!

I have been looking for firmwares for these drives but have found none as Hitachi only gives them out when needed, don't think i'll get them when I ask

I found some references to 146GB firmwares while googling: S21E & S23C

Does anyone have an idea?

They appear to be HPA "clipped".

Easy to fix on IDE drives (MHDD will do it), but not sure about SCSI.

MHDD returns an "IDE only" message so this won't work

Only one thing can work with SCSI HDD, PC3000- SCSI version. So you must send your drive to a lab, where's have that tool.

That's right. You have no free tool that can work with scsi drives.

Thanks for the info

Sending them off to a lab will most likely cost more then getting 146GB drives so I'll leave them as they are now

I can help you, if you want. I'm Vietnamesse and my lab have PC3000-SCSI.
