For some reason on both of my computers all my hard drives are being detected as ATA33 but they are all 100's. I have checked the cables and they are not the old kind (not sure of the terminology). And disk access is kind of slow.
During boot up there is a brief line, (can't recall exactly what it says) but something to the effect of not detected 80 IDE cable.
They are Maxtors:
Formatted Capacity: 40.9GB
Interface: 40-pin ATA-5
Data Transfer Rates: 100MB/s (UDMA)
