Be careful not to use an ATA100 cable for the two drives as you will lose data on your ATA33 drive. Use the older style 40 wire cable rather than the newer 80 wire connection. My ATA100 drive certainly seems to operate at much higher speeds than the older drive but this could simply be due to faster seek times.	Guest (0)

The reason being that most hard drives can only transfer a little faster than 33MBs, and they'll only go this fast on very rare occassions. One of my hard drives (7200rpm Maxtor) boasts a max transfer rate of 42.8MBs, but it only averages about 36MBs, and that's only when copying a single large file. For day-to-day apps a 7200rpm HDD would be transferring data around 32MBs, and a 5400rpm one at around 25MBs. If you put this on a 33MBs bus, you're not really cramping its style except on the rare occassions where it dumps its cache and send a chunk of data really quickly... What am I saying? 33MBs cable is fine, unless you're pedantic:) Erin	Guest (0)
54803	2002-06-17 09:41:00	I have an ata 100 20gig maxtor 7200rpm drive and a 6.4gig 5400rpm ata33 drive on a 80wire cable, and both work sweet as, but i think they r working at there top speeds anyway, (well within reason) does ne know y a bios would not detect a new 40gig maxtor, but everything functions normally anyway and all 40gigs show in windows?? cheers	Guest (0)

Use the older style 40 wire cable rather than the newer 80 wire connection.' other way around. with ata100 drives you need 80 wire cable and an ata33 will run just fine with an 80wire. the extra wires are sheild wires which prevent data loss/coruption at high(66,100,133)speeds. in fact with alot of new motherboards will only run at 33 if a 40 wire cable is used regaurdless of drives.(small catch for those with dvd drives)	Guest (0)
