My G3 B&W 450 has a Rev 2 motherboard and the CDM402 IDE controller chip. It works OK with an EIDE ATA33 hard drive but cannot pick up either an ATA100 5400rpm Maxtor from an eMac, or an ATA133 WD 7200 rmp hard drive. Both are 40GB so well under the 128GB limitation.

An ATA33 Quantum Fireball CR 6GB is detected. Are modern IDE Hard drives compatible with older EIDE Hard drive controllers? or is my CMD402 chip frazzled? javascript:emoticon('')

I have a similar problem when I install a SuperDrive Pioneer DVR-111BP, as this is not detected, yet the Sony CRX-140 CD Burner from my old G4 is detected.

Will a PCI hard disk controller card solve my problems? OWC are doing some good deals on both IDE and SATA controllers.

I would like to replace the old Quantum drive with a larger , faster hard drive and install Mac OS 9.2.2.

Any suggestions?

Assuming that you are on top of the jumpering for master and slave drives (beware the drives that have a 'single' jumper when they are alone), and that you are using good-quality 80-wire cables, there is little further that you can do but invest in an ATA-133 PCI card. Not only may you then have future 48-bit LBA capacity for drives of more than 128GB, but also, in case the present controller is playing up, an ATA controller that is independent of the MLB's controller.

Good luck.

Hi Thanks for the info.
I have actually tried using 2 of the EIDE 40 ribbon cables and 2 of the Ultra ATA 80 ribbon cables and got the same results.
It actually died on Saturday, so I'm planning on using the tower to house a PC project. I have kept the processor, ATI Graphics Card, should I ever come across another B&W.
It did well to last 10 years, so I'm well chuffed.
Looks like I'll have to use my G3 iMac to run Mac OS 9.
Cheers
Pete

Last thing to check is that on some newer drives, you may need to set a jumper on the drive (look up the model number online, it is often not marked on the drive itself,) to enable 'legacy compatibility' mode.

Hi
I've tried a variety of drives including EIDE, ATA66, ATA100 and ATA133 but none are working now.

I've just sold the machine for parts on eBay, as it's not worth spending AUS$100 for a machine that goes for $30 here on eBay.

I've also just got a Classic II running Mac OS 7 and Word 5.5. I'll use my G3 iMac for all my Mac OS 9 stuff.

Cheers
