Comment: Tyan S1846 ATX Homebuilt
Pentium II 400 mHz
128 MB RAM
Windows 98 Second Edition
IBM EIDE
Iomega ATAPI Zip Drive
Adaptec AHA-8945 - IBM DGHS 9GB HD
Adaptec AHA-2940U2W - Internal CD-R/W and Iomega Jaz Drives; External Seagate
HD(!) My homebuilt machine boots from an 18 MB IBM EIDE HD that is partitioned into
two 9 GB logical drives. It also has two Adaptec SCSI host adapters. The
AHA-8945 is a combination IEEE-1394 video and host adapter and it controls a 9
GB fast IBM SCSI drive that is used for IEEE-1394 digital video downloads. A
second Adaptec AHA-2940U2W host adapter controls an Iomega Jaz drive and a S&F
CDR8020 CD R/W drive. Everything has been working fine for the past six months. I recently acquired a Seagate ST446452W 47 GB UltraSCSI-2 SCSI drive and
connected it to the AHA-2940U2W external high-density 68-pin connector. I ran
FDISK /STATUS and saw all the drives, but ever since, FDISK finds no drives,
and I can't get to the Seagate to partition it! I am baffled. I have gotten
another copy of FDISK from another machine in case the file I was using was
corrupted--same result. Today, I got Tyan's BX46M200.ZIP updated AMI flash bios
file and successfully loaded it into my machine. I ran FDISK
and it worked--once only! Subsequent tries produce the message: "No fixed disks
present." However, Windows' Device Manager finds the drive. On the suspicion
that the external cable might be defective, I hooked up the new Seagate drive
with an internal ribbon cable and shorted the active terminator pins on it--no
change.

Reply: (edit)Have you gone into the Bios setup to see if all your hard drives are set up in there. You might want to try that. And did you get the right Bios upgrade?

Reply: (edit)Seagate advised to check several settings in the Adaptec BIOS, and to try the Adaptec version of FDISK, AFDISK, a program that comes with their EasySCSI utility package. No luck. Adaptec says that FDISK can get confused by two host adapters with fixed disks on each, and suggests that I try pulling the other host adapter and trying FDISK on the unformatted drive with it being the only one in the machine. I'm going to try that at lunch, as well as checking whether I need some different toggles with the ASPI driver. Talk about plug n' play . . . .!
