That sounds bass-akwards to me... as ATA133 absolutely MUST have an 80wire cable, while for an ATA100 HDD it is merely a really good idea
ATA66? have it bronzed, and use it as a paperweight as it isn't good for much else.
"PATA" is also another synonym for IDE, EIDE, etc...
There frankly is no current use for a 40wire cable as all the drives
that can actually use them are old and slow.
Would you like to borrow my 40wire cable storage device?
It's circular, stands about 20" tall, sits next to my desk and it
gets emptied about once a week... thinking about it you probably
already have one....
Yes, what I'm saying is that for any computer hardware you actually
want to use, you DO NOT want to use a 40-wire cable on it and I heartily recommend putting them in the trash.
