Amongst recent purchasing thoughts, one persistent one is that I need to put a new hard drive in my aging G4/400. There's a 120GB drive from Seagate that I'm eyeing, but before I purchase it, I need to know if ATA-100 is backwards compatible with ATA-66 since that's what the old G4's used. I've done a bit of Googling on it and from what I can tell, ATA-100 is backwards compatible but obviously I don't want to make a purchase without knowing for sure.

go for it, it works notta problemo But of course for maximum value & performance, you could get a Serial ATA drive & controller card, which could also be moved to a G5 later on should you get one.....
Signatures are ugly. Bitchy women are ugly......YOU do the math :)

While a G5 would definitly be a kick-ass computer to get, it's not in my deck of cards anyime soon. Thanks for the reply, though! I think I'll go about getting the Seagate drive now.

Both my Seagate 80gb 7200RPM ATA100 drives have been flawless (1 in my Xbox, 1 in my PC). Good luck!

That's great to hear! I checked around the net for some comparisons and it seems as though Seagate comes up as being pretty reliable. There's a 120gb 7200RPM ATA-100 Seagate drive that I'm eyeing that seems to be aat a decent price. Here where I work at in IT [for the summer] I asked one of the guys I work with for his opinion about some of the current hard drives available. He said that back a few years ago, he would have recommended Maxtor, but their quality has severely deteriorated . With Western Digital hard drives, he wouldn't buy it in the first place, and that Seagate has always been pretty solid.

I guess only experience can tell. I've had about 6 or 7 different hard drives, and the only ones that every crashed were 2 Seagates ... the other 5 Maxtors are still running, one of them is a 4.3GB thats at least 6 years old or so ...

Yes, as long as you are staying below that magical 137 (?) gig mark. Higher-capacity drives will cause some trouble as only part of their capacity is recognized.
I don't suffer from insanity, I enjoy every minute of it.
