sick disk?!

[Root]

HALP!
	Nidhog's disk is very sick I have a brand new(6 mo.) miniscribe 3085,
an even newer(1 mo.) WD 2010 controller, and a two week old 3b1 power suppply.

Nidhog had a 7300 1 meg on board 2 meg expansion dos board and am running 3.50 OS.

The disk works well most of the time but occasionally the hard disk 
makes an awful noise ``brrrrrrrr...spriong-griong-griong''. The status
manager(smgr) flickers or dies sysinfo responst /dev/rfp002  can't 
read superblock. The disk is gone. Well diagnostics ran and responded
error on check read when ever this happens. The only thing I can think
of is bad power. If any one out there has had a similar experience :*(.
Or has any helpful suggestions Please Let me know. 

The only consistant response I got from the diags was that block # 3168 
was bad. How I convert the block that diagnostics gives from surface test 
to a logical block that I can give to the badblock table stuff?

Thanks in advance.
