I have a DELL sitting on my desktop with a Maxtor drive. With a stock install (the i810 chipset doesn't communicate capabalities very well to the kernel) the hdparm -t showed 4.78Mb/s With -X66 it showed 31.58 Mb/s, with -X68 it still showed 31.58Mb/s. I run it at ATA/33 though it says it can do 66 because the performance flattened out, and I risked more errors at 66 for no apparent gain in data performance. Civileme
