How can my 733 Digital Audio recognize a Hard Drive bigger than 130 Gigs???

Simple as pie. Buy an ATA or SATA PCI card. That's the only way, and then the sky's the limit. PCI card, not PCI-X, or PCI Express. You need to make sure it is Mac compatible too. Sonnet and Acard are probably the most popular brands. Maybe you know all this already, though. Have you run out of PCI slots? A used ATA66 card can probably be bought for about $10.

Intech has a driver to do just that. Its worked pretty good for me in the past...

Well I'll be...Should've known what I hear ain't possible is.

For the price of the software, though, might as well buy the PCI card, then you don't have to buy the $90 suite, and you can do SATA instead. Now I know there's no hack for SATA on a DA motherboard...

Yes, but he could also use this on multiple machines, were as he'd have to buy multiple cards if he wanted to use do this with more than one machine.

Well this machine was working for a day or two with the new 500 gig drive in it, but only recognizing 130 or so. The original 60 gig master was also in the machine, and my roomate threw in his DVD drive to load some software. I was planning to try either the hardware fix or the software fix for the new 500 gig drive, the next day, when my machine decided to throw a hissy fit and turn on with, chime, fan and drive, BUT NO VIDEO. I've tried resetting the PRAM, Removing the RAM cards, and starting from a CD drive with NO LUCK. Does anyone have any idea what could have happened and how to fix or troubleshoot further.

Thanks, Jay.

I just had that problem with a Quicksilver. I swapped the 32mb Geforce MX2 video card I had in it with a 64mb PC flashed MX2 I had in a Digital Audio and the video came on fine, but I put the original MX2 into the Digital Audio and it worked fine, so the why and wherefore of the Quicksilver's original no video remains a mystery. Did you try reseating the video card?

Here's an Accelerate Your Mac page that addresses the original large capacity question.

So if the 128GB limit on the DA (and other early G4 era and before Macs) can be hacked, where does the limit exist? In the ROM? Why can't a firmware update correct it?

Because no-one's written one is the short answer.

Interestingly I found that Ubuntu Linux was able to install itself into the unused upper portion of a 160GB drive.
