Hi Phillip,

Either the Ultra ATA 133 or ATA 100 will work. The ATA spoec says that
either 66, 100, 0r 133 will work (with the driver or interface slowing down
to match) to be backwards compatible.

The Ultra SCSI is a completely different type of interface and will not
work, and as you mention, SATA won't work either unless the MB has SATA
ports. (there is such a thing as an ATA to SATA adapter, but isn't practical
as long as ATA drives are still available).

Subject: Re: [PCBUILD] HD replacement compatibility


 
Thanks for the reply Ray and the links which were very informative but I  
still have the basic question of what will or won't work in my PC. I mostly
use  
it for web browsing (dial-up) and word processing. No gaming or other
resource 
 hogging activities. So performance needs are minimal. 
 Hard drives on the before-mentioned sites are listed as IDE Ultra ATA  100,

IDE Ultra ATA 133, Ultra320 SCSI (60 and 80 pin)and SATA. I know I can't
use 
the SATA but am in a quandry as to which of the others would be  compatible.
Also, if I do use a HD that doesn't use the ultra DMA standard, will  I have

to make an adjustment in the Bios to accomadate it?
 
  Thanks for any suggestions as I'm afraid my present drive is about  to
jump 
ship!!!
