Is it normal for WinXP to poll my older SCSI devices?
William Cheng
I have recently upgraded to WinXP. I still have an old SyQuest 200Mb drive
(those archaic large cartridge types) hooked up to my AHA-2930CU adapter.
All went relatively well, I was just wondering, I noticed that the SCSI card
light flashes a every second or so and my SyQuest drive light also flashes
with it - is this normal? Does it slow down my system? It seems as though
its polling the drive - it doesn't happen on my Iomega ZIP internal or CD-RW
also on the SCSI chain. Is there a setting I can change to stop it from
polling my SyQuest drive.
Thanks, William

XP will try to "autoplay" just about any media device, so it's probably
reading the media change status. Find the setting to turn autoplay off for the
SyQuest device. I use the Microsoft Powertoys "TweakUI" for XP, and you can
control autoplay independently for each device on the system...
