[comp.sys.ibm.pc] Need help formatting 20M hard disk on PS/2 30

dulimart@cpsvax.cps.msu.edu (Hansye S. Dulimarta) (12/03/89)

Hello netters,
	I need some suggestions from you. A friend of mine just bought a
PS/2 model 30 with 20M hard disk and 80286 processor. When he cheked it
with the starter diskette that comes with the machine, it recognized the
harddisk as installed (the harddisk is really there of course !). But it
has not been formatted yet. When he wanted to format the disk the DOS
always returned the message "Invalid drive specification". With this
message I believe that this message means the harddisk is undetectable by
the DOS.
	Could somebody help him out (or help me out to help him) with this
problem ? Should we do a low level format ? But how can we find the address
in the ROM ? One more information the harddisk is ST251x type (I thought
there is one more letter after digit 1 but I couldn't recall what it is).
Please e-mail me whenever possible or post to this newsgroup.

Hans.
