IDE Drives for Recording ?

[advid]

My 9600/300(w. G3/500 Card), OS 9.2, 512 MB Ram : internal 4G 10,000x SCSI HD for OS, Internal 2 x 18G Segate U2W HDs and 2 x 34G U2W HDs for audio recording. It crashed twice in two weeks since the last time I tried bouncing tracks. After I restart the 9600, it can't read my internal 2x18G HDs (soft RAID formatted into a 34 G HD). I then reformatted these HDs and worked for one week later, the computer do not show up my external 2 x 34G U2W HDs...I then reinstalled OS and everthing ( Protools 5.1.1, Plug-Ins..,etc.)

But Now that I am statting the next busy season, I 'd ordered an Apple silver G4 /733 to work with. My guestions are as follows :

1. Can I install more IDE drives (say for two units of 7200x ATA 60G HDs inside the G4/733 ) apart from the original one that come with the silver G4 ? Do I need any optional PCI cards to do this ?
2. I plan to use these IDE drives for recording/editing/mixing/mastering purpose. For your reference, I also have Magma 7x extension bays, AD-8000,USD,ADAT Bridge,888/24 IO, Rosendahl Nanosyncs, Protools 24 Mixplus, 2 extra Mix Farms and 2 DSP Farms.
3. I also ordered the DIGI 64 Kit for the U2W drives if the answer for the question 1 & 2 is "Never go with the IDE Drives".
4. I am running all MIDI stuff on another G4/733 using Digital Performer 3.01, with adaptec 29160 PCI card with a 18G U2W HD internal. If I can use IDE HDs for the Protools system, then I can hoop up the 4 U2W HDs that originally connected with the 9600 computer.
5. How can I use the external SCSI CD-R or CD-ROM players with the G4/733 ? Is there any PCI card I should purchase apart from the 64 Kit ?


Please Help ! I did search the topics that concernning my questions but I can really get it right.

Thanks in advance !
