SCSI HD stops working after a while

Hi everybody
I have a serious prolbem with my SCSI Controller. When I copy a lot of data from the Network or Install something from the CD my Harddrive stops working after a time. I am pretty sure it is the fault of the HD or of the SCSI Controler. But have no Idea how to solve this problem. I already double chekced the termination of the SCSI Bus. And right now the HD is the only Device at the SCSI Bus. But it still hangs. One more to the error, for example when I copy something over the Network the HD Activity LED is flashing, but just before the crash it is lit for 4-5 seconds and than stops working until reboot.

My System:

AMD XP 1800+
Soyo SY-K7V Dragon+
768 MB Ram
Tekram SCSI DC-390U3W
Seagate Cheetah 36ES
Soundblaster Audigy Platinum


please help someone.
S.

At a guess its something to do with pci bus one way or another, go into bios and make sure bus mastering is enabled and also check on IRQ sharing. Basically the Scsi controller should be on i.e.: IRQ11,or 9 and/ or 5 I think, but usually its best on its own IRQ and not sharing with anything, best left on IRQ11, I swapped the cards around on the PCI bus and found a happy medium. But Iam still thinking about it, Scsi can be a weird beast! Other things to consider is to check on other devices to ensure they are not causing the problem, like a process of elimination backwards from whatever you last did to the system, remove things until you are certain which piece of hardware is causing the problem.
Also do you boot from the scsi drive?
Have you over-clocked the FSB at all?
Also check the Teckram and Hard disk instructions for its own bios requirements and on disk jumper settings which Iam sure you have done.

Basically more info is needed including cable, and other hardware descriptions, board description etc.

thanx for reply

Yes I boot from this drive, actually it´s the only HD in the system.
No I haven´t overclocked anything at all.
I already checked everything in the manuals and can´t find any solution...
About the cables and everything. I used the standard cable and the Terminator that is coming with the SCSI Controler.

Op system?
dunno. like I said strange beasts but you will have to just work through everything until you find it, could be one of 50 things. Just methodically start with the simplest thing first and do the process of elimination.

What I have found is that by understanding SCSI to a degree you can usually work out whats up, have a read and good luck!

Just a thought from my owm memory of something simular, this is how Iam thinking > Ok all is ok until you want it to perform to its limit right?
Well what I have seen in my own system particulary when I try and o/c it bigtime is I find one component or another will suffer lack of power supply when high demand is needed everywhere else. Usually my scsi disks or even IDE disk will do its lil' seek then stop and then its good bye until restart.

Basically what Iam trying to say is when your HD wants to go max' it requires more power for it self and the PCI bus and perhaps your other components are using enough to not allow your disk to get enough!

This is why some people complain about weird un-solvable problems because everytime they trouble shoot the problem shifts but it really is just a power supply problem (PSU), I even had a Enermax fail this way so I would suggest at least a 350w PSU of quality.
