[comp.unix.microport] Questions re biiiig Maxtor disks

mark@intek01.UUCP (Mark McWiggins) (12/01/88)

We're upgrading to a 386 Unix and getting a 300+ MB disk to go with it.
I have a couple of questions about this:

(1) Do you have one of these?  What controller are you using?  Is the
combination working for you?

(2) Is the difference in response time between a 28ms disk and a 16ms
disk very noticeable under Unix?  (Maybe a silly question, but 28ms
Maxtors are on sale ...)

Thanks in advance.  I'll post a summary if there's sufficient interest.

I'm running a 20mhz 80386 system with a Maxtor XT4380E (330mb 18ms)
hard disk on a Western Digital WD1007A-WA2 controller.  The only
problems I had were in sorting out the bad sector handling . . .
basically, letting the board handle all cases where a track had a
single defect, and feeding the few defects remaining to Unix.  Big
disks can have lots of defects, and Microport V/386 barfed well before
I got the whole defect table loaded in :-(.  Letting the WD1007 handle
everything didn't work because it marks a track bad on the second
defect, and Microport barfed there as well :-(.  The current combo is
working like a dream :-).

Haven't any idea.
