Desktops: Need Help, Data Corruption issue
I have checked a few more things...

First of all The SATA card is a known problem in the system, it has ben more or less buggy in each 2 different systems with 4 different drives, and the symptoms are identical. The only reason I mention the SATA issue is that I suspect a resource conflict as the cause, in which case is it possible that the USB HDD corruption issue is a reciprocal effect of the same conflict? Note that only USB HDDs show corruption, in addition several usb HDDs that were corrupt, reformatted and corruption is not happening anymore. The only change in usage patterns is that they are NOT being connected to the USB ports on Computer 2, the same computer as the SATA issue. At this point Computer 1 seems to be ruled out as a factor in the corruption along with all 18 HDDs and the USB to P/SATA cable. The Ximeta enclosure is still suspect.
I keep forgeting to menton an issue in involving Computer 2 and the Ximeta, Occasionally when transfering large amounts of data the Computer 2 would freeze. The trigger seems to be 1 or more Winrar compression jobs and transfering several gigabytes of data through USB, after about an hour pagefile usage goes out of control (I only know because I can hear the drive seeking.) at which point I have to power off the hardware.
Resource conflicts are not possible with P4 or newer machine

PCI in P4 and newer machines create an impossible to create the old IRQ, DMA issues prior to this day. That issue was soundly cured by a slight rejiggering of how PCI ran those lines from and to the controller chips.
How do I know this? I had the luck to design some PCI cards and had to eat live and breath PCI data for years.
So what's stopping you from removing parts that give trouble?

P4 or newer machine

"P4 or newer machine" this thing is a very early Pentium 4 Socket 423 RDRAM system, so is that a rough guide line, or does mine suck like a PIII? I do know the bios sucks on this thing, the motherboard is a oem Asus P4T, Search for "HP Alcatraz".
The change I'm talking about occured

Somewhere in the Pentium 2 days. It had to be done because it had to be done. It is no longer possible to have a resource conflict in new hardware. Yes we can run out of resources but that's not the topic.
Back to the top.
You have some iffy parts. It's sad they didn't die outright.
