Here is a format.dat entry for the Maxtor LXT-200S which I put together
when we were evaluating drives for the Sparcstations. The entry works,
but we didn't buy the drives. The Maxtor uses up a *lot* of power and
gets a lot hotter than the other drives we've evaluated. Note also that
on the Sun you only get about 160MB out of the drive rather than 200...
disk_type = "Maxtor LXT-200S" \
: ctlr = MD21 : fmt_time = 2 \
: cache = 0x5c : trks_zone = 6 : atrks = 0 : asect = 1 \
: ncyl = 1314 : acyl = 2 : pcyl = 1320 : nhead = 7 : nsect = 33 \
: rpm = 3662 : bpt = 16896

If you use disk_type = "Maxtor LXT-200S" \ : ctlr = MD21 : fmt_time = 5 \ : trks_zone = 1 : atrks = 0 : asect = 1 \ : ncyl = 998 : acyl = 2 : pcyl = 1314 \ : nhead = 7 : nsect = 56 \ : rpm = 3600 : bpt = 33920 You get around 195MB. That's the entry we use. It yields a total of 391,216 sectors. Eduardo Krell AT&T Bell Laboratories, Murray Hill, NJ UUCP: {att,decvax,ucbvax}!ulysses!ekrell Internet: ekrell@ulysses.att.com

That's the entry we use. It yields a total of >391,216 sectors. Eduardo, I call your 391,216 and raise you 784 sectors to 391,300. Try this format.dat entry: disk_type = "Maxtor LXT-200S" \ : ctlr = MD21 : fmt_time = 5 \ : trks_zone = 1 : atrks = 7 : asect = 1 \ : ncyl = 1300 : acyl = 2 : pcyl = 1302 : nhead = 7 : nsect = 43 \ : rpm = 3600 : bpt = 33920 Barry Lustig Advanced Decision Systems barry@ads.com
