1. PlexWriter with Adaptec 2940U2W causes Win98/95 to crash
Hi, I'm wondering if someone could help me. I've got a new computer
with an Adaptec 2940U2W SCSI adapter, and whenever I try to access my
external Plextor PlexWriter CD-R within Win98, the system either crashes
right away, or freezes a few minutes later. I've tried using Adaptec Easy
CD Creator and Adaptec CD Copier Deluxe.
I installed EZ-SCSI 4.03, and upgraded it to EZ-SCSI 5.0. I've upgraded
the 2940U2W's BIOS firmware from 2.00.0 to 2.00.1. I installed the
PlexManager 96 that came with the CD-R, and upgraded it to 1.67. I've
upgraded the ASPI to 4.57. I've upgraded the PlexWriter's firmware to
1.04. I've tinkered with the CD-R's settings in Windows and the BIOS
settings for the 2940U2W. I even switched from Win98 back to Win95, but
the problem still persists.
I'm usually able to successfully do a "dir" of the CD-R from a DOS window
in Win98/95. I'm able to execute a few simple commands accessing the
CD-R when booted up under DOS using DOS ASPI drivers.
I've also got an internal Plextor UltraPlex CD-ROM on the same cable as
the CD-R (it's an internal 50-pin to external 50-pin cable), and the
CD-ROM works fine. The CD-R is terminated by its builtin DIP switch
Plextor's phone tech support said this is a known problem with the 2940U2W,
and that it currently doesn't work right with the PlexWriter. They said
I need to talk to Adaptec and see if they have a fix. They said it must
be the 2940U2W, because the PlexWriter DOES work correctly for the 2940U.
Adaptec's phone tech support said there isn't any known problem with the
2940U2W, and it sounds like it's a problem with the CD-R. When I told
them that the CD-R is reported to work with the 2940U, the guy was
surprised and said "Then it doesn't sound like a problem with the CD-R."
He suggested I switch from Win98 to Win95 (Adaptec does not support Win98).
However, Win95 experiences the same problem -- I tried.
Seems to me like I'm getting the run-around.
Does anyone have any experience or knowledge of this problem?
Please help -- I've got a $650 CD-R and a $370 SCSI card that don't
like each other. :(
Here's the rest of my system for reference.
