Unable to format new HDD

[DigitalChuck]

I'm trying to add two more hard drives to my G4 Quicksilver Dual 1ghz, 1.25ram. I have two 80gig drives in the double carrier.

Help if you can,
My system crashes every time I try to format my new HDD.
Disk Utility recognizes the HD, but crashes. Any thoughts or suggestions greatly appreciated. Thanks

Here are the particulars
I have 2 80gig drives installed on the double carrier as master & slave
2xHDD: Seagate 500gig 16mb Model: ST3500630A - set as slave
PCI Card: Siig Ultra ATA 133/100 pro

Below is the error report I get:

The SIIG card driver may be giving you problems. But, first change one of those 500GB drives to master, and try again. If they are both connected to the same bus on the SIIG card, then you should have one master, and one slave. Should also work with both set to cable select, but check the documentation with your SIIG card. Both set to slave should _not_ work.

[DigitalChuck]

They were both initially set to master on different bus and cables. Mac documentation says the Ultra ATA will not work with cable select, so I started with them set to master. The SIIG documentation is a joke!

[DeltaMac]

Then, you have 2 drives connected to the SIIG card. Jumper one as Master, and the other as slave.
You should also try the SIIG site for possible updated drivers, or firmware updates (or try acard - they make the SIIG cards. )

It's the card. SIIG just sent me an email. It's a known problem to them that the card does not work with "large" Seagate drives! WTF!!

Hello,
Please try to return the card thru your direct vendor.
This is a known problem with only the big Seagate hard drives that we currently do not have a solution for it
