Subject: Help wanted


I've tried several times to post this question to I-AMIGA (on bitnet), but
some times the message were stopped ('list is held'), and other times the
messages seemed to be distributed, but no answers came ....

I have a ST296N harddisk, and an A590 harddisk-controller. Interleave 1:1
is kind of sssslllloooowwww. (100 K/sec, due to bug in the REV 8 ROM). I've
heard that interleave 1:2 is faster (400 K/sec). REV 7 ROM is without this
bug.

I've tried using the hdtoolbox program that came with the A590. There were
no way to select interleave value there.

I've tried putting an entry for the drive in the DEVS:mountlist file, and
found that if the partition started at cylinder 0, a low level format would
be done.  But, the interleave value in the mountlist entry was ignored.
(ARRGH!)

I'm using ARP1.3, but the mount command is from the Demo version of
CrossDos.

What i would like to have is :
  - Email address to seagate. (if one exists). Since this is a BUG,
    they ought to do something.
  - Documentation of the hddisk.device/xt.device/scsi.device on the A590,
    or information about where to get it.
    Then I may be able to write a program that sends the correct SCSI
    packet to the drive.
  - A utility program that supports low level format with different
    interleave values.

I hope you or one of your friends know the answers .... I don't want to
spend a month with a disassembler to find the answer myself.

Sincerly,
Tor Egge
