Hello Again Rob,
I think that I have run the test you suggested. Here are the scores: Speed av. 4.31x, Start 4.28, end 4.35, type cav. I did get a message, "Error, Logical Block address our of range." The manufacturer is Ritek. Random 67ms, 1/3 68ms and full 84 ms, CPU usage: 1x 6%, 2x 10%, 4X21%. 8x N.A. Surface scan: good 100%, damaged 0% bad 0%,. Does this help?
