I'm trying to install a new scsi disk, a dec dsp3210s, on
an existing system, and am having problems....

dmesg says: sd3: 2049mb 3045 cyl 16 hds 86 s/t 4197520 sec.

When I do the math, I get 4189920 sec.

But a site (http://hpline.epfl.ch/HPUX/tools/disktab.html)
gives the specs for this drive as
3051 cyl, 16 hds, 86 sec, which is a different number of sectors.

Another site (theref.deepthought.rl.af.mil) [excellent site]
gives 3045cly, 16hds, and MZ for the s/t (I assume mz=multiple
zone recording).

So, what numbers do I use, and does disklabel really get the
math wrong, or does it know something I don't?

-------------------------

When I used my more conservative sec count, i started getting
soft errors when copying massive amounts of data to the new
drive:

sd3(esp0.0.0): DEFERRED ERROR, key = 0x1

and

sd3(esp0.0.0): soft error (corrected), info = 2779720 (decimal), data =
           00 00 51 40 17 06 02 00 00 00
	   
I assume these are bad sectors.  How do I map them out?

How can I thoughly test the drive for bad sectors before using it?

-------------------------

tar, dumped core in the middle of the transfer, perhaps due to
the bad sector, perhaps not.  Don't know, but I wouldn't think that
tar should dump core at all.

Thanks for any input you can give me!
