Unfortunately, two attempts to install Win7 x64 Ultimate have failed due to "missing or corrupted files" one time, and "you need additional drivers" or words to that effect the second time. I don't know if the new slim drive is bad, the DVD has gone bad (it was used to build the H61 system a few weeks ago), or something really sinister is going on.
I ran a memory test without incident, and did a format of the main partition, taking about 20 seconds for 128 gigs. There's a tiny 120 meg partition marked as "system", and the remainder, partition 1, is shown as an active partition.
I've decided to not worry about it tonight. Enough is enough.
