Random A3000 lockup problems

[Prmetime]

Hi.  My A3000 has a history of locking up at odd times.  Each time it locks up, the Hard Drive light is on.  Usually the hard drive then spins like crazy (like the partition is invalid) upon rebooting.  Rarely is the HD or a partition invalid and Quarter Back tools fixes the problem if that is the problem.  

Just so you know, my A3000 has all of the latest chips (WD ver8, Super buster Rev11, DMAC 4, Ramsey 7) full memory on the MB plus a Warp Engine 040/40 card with 32 Megs of Ram. I use OS3.9 with Boing Bag 1 and 2 installed.  I use the stock file system.

The maddening part about this is that it will happen at random.  Some mornings I will turn my machine on and it is finicky right from the start.  Other times it will take an hour.  Other times it runs fine. I even wiped my HD and reinstalled the OS hoping that the problem was a overly patchy version of the OS.  Yet I still get the crashes and wierd file things going on (like the drive icons changing their positions on the workbench and they will not go back to the  original positions even if I snapshot them in the positions I want them to be in). The only thing that seems consistent is the HD light is on when it locks up.

Does anyone have any ides?  I don't know if this is a HD problem, a file system problem, or something else on the motherboard.  I appreciate any help you can give me.

When I was trying to Get a Cyberstorm MK II to work, I did all of that.  It doesn't seem to have fixed the problem.  :-(

The Hard drive is connected to the system using the internal SCSI cable of the A3000.  However that is terminated is all that has been done with it.  The HD istelf is a 1Gig Seagate that I picked up back in 1994 or 1995.

Given that the primary RAM is now on the GVP Warp Engine accelerator and I haven't done anything with the memory since I installed it all those years ago, I wonder if this will really make a difference?  Still it wouldn't hurt to try it if nothing else is wrong.

My A3000 is still in its original Desktop Case.  I happen to like that case quite a bit.

As for the cable, it is the original cable that came with the machine.  I don't know the max transfer rate.  Where would I look that up?  Where would I get another cable?  Can I use an aftermarket one or do I need to find an original one without much use?
