Beige G3 shuts down with heavy drive usage!

Hi guys,

As some of you will already know, I'm currently having fun restoring a thrift-store-salvaged Beige G3 Tower - I've successfully upgraded the RAM, created an Admin account on the existing 10.2 install, and upgraded to 10.2.8. One of my first priorities is to get away from the amazingly slow and tiny stock 4GB internal drive, so I've dug out an old UltraATA/133 80GB drive. I understand that the internal IDE bus on this machine is far slower than this drive supports (I'm planning on getting an IDE PCI card ASAP), but even if just for the extra space, it's a good upgrade.

So, I've just partitioned the drive into two sections - one 8GB partition for my OS install, and the rest for data and application storage. However, I'm seeing an odd glitch with this setup: I've got the original 4GB drive in it's normal position, and the "new" drive connected to the CD drive's IDE cable and power line. OS X is happy to detect the bigger drive, and was able to partition it just fine - however, when the big drive is installed, and sustained and heavy drive usage (on either drive) causes the screen to go black after a couple of minutes! I can still hear the drives clicking away for a few more minutes, but then those stop too and I'm forced to hard-reboot the system. I've now seen this when trying to install the various updates that come along with the 10.2 --> 10.2.8 update (security updates, etc.), repairing permissions on the stock drive, or trying to "CarbonCopyClone" the stock drive onto the smaller partition of the new drive.

Any ideas? Am I just pushing that slow internal bus further than it was meant to go?

Thanks!

Off-hand, an immediate suggestion is to take in Franklinstein's comment about Royal VRMs in the Beige DT and MT (in your other recent post, about ZIF CPUs). Beyond that, some test measurements of the voltages delivered to the MLB from the PSU (with and without heavy load by the drives) may be in order.
