Suddenly cant open scsi harddrive

[Imerion]

I have two harddrives in my A4000. One standard IDE and a SCSI one. Untill now everything has been working perfectly, however, suddenly I could not access my scsi HD.
The drivers are from GVP and was installed when I got the computer. I tried to start the "gvpscsi" file which was in one of my eb drawers when I got this error :
"software failure (error #87000004)
Wait until read/write has finished
And then I had two options, wait or restart

Exactly before this happened, I had installed Whdload and the XPK libraries. Obviously they destroyed something.
When I start from the GVP install disk, it works fine. So it is something in my WB which does not work. (I have tried to reinstall it, but it does not help.)

Please, help me...

I removed the XPK-libs. Now the gvpscsi-file wont crash. I can still not access the hd though...

Yes, the error didnt seem to have anything to do with that at all. It was DefIcons interfering with NewIcons in some way. Not shure how it happened, but when I removed DefIcons from my user.startup file I could access it again. I was completely wrong, it had nothing to do with scsi. Oh well, atleast I learned a lot.
