So I made a data storage box with a collection of old hard drives and put Windows 7 on it for ease of use.
I used the disk tool in Windows 7 to create a single spanned volume with 4 IDE drives and two SATA drives with a total space of 1.18TB. I can write to this disk fine, and transferred a full TB of data to it, no issues.
While accessing the data(streaming .mkv files over a wired home network)the computer started to freeze up, randomly.
After one freeze, it wouldn't restart properly so I did a "Recovery". This made the spanned drive disappear.
I disconnected the two SATA drives and connected them to a second SATA controller on the same motherboard and restarted, which restored the spanned volume.
At this point, I removed ALL data from the spanned volume and ran a checkdisk on it with "fix errors" enabled. No errors were found...
From what I've read, it may be a flakey controller, any advice on how to better find the underlying problem than "hoping" its a flakey controller and abandoning the motherboard ?
The motherboard is an old MSI KT6 Delta with an Athlon 2300 CPU and 2GB of DDR400 RAM, tested for errors and found to be working.
