CDC Disk repairs

[Bill Kamp/MetaComp Resp. Marty Storma]

I have a CDC disk out of my SPARCStation, 
I believe it is a wren, and it needs repair.
Can anyone provide a number to call for information?
I believe this number was on the net a couple of weeks ago.

The disk description is:
Sun #?: 327MB HD Disk, NO OS, PN:370-1153-02-A, FRU:555-1005-03
CDC#?: MN94171-327, PN: 77777107, SN: 03088084, Lot O-8924,
UPC: DFAX099084.
