Hej Mikael
Hvorfor sætte flere IDE enheder på samme IDE-kæde - det kan nedsætte 
hastigheden.
Mulig løsning:
Det vides ikke om produkterne herunder virker til Mac, men det er da 
værd at undersøge:
Du kunne sætte DVD drevet i denne:
ADS Pyro Firewire Drive Kit
Pris incl. moms  970,00 kr.

Dette betyder at fuld firewire hastighed kan nås: "# Oxford 911 chip".

OXFW911  High Performance IEEE 1394 to IDE/ATAPI Bridge:

FireWire/IDE bridge Before purchasing a FireWire case, Anthony Burokas 
suggests checking whether it uses the "newer FireWire/IDE bridge system 
announced by Granite Digital at MWSF01 that allows external FireWire 
cases to make full use of the IDE drive's speed. Other cases may top out 
at 11-13 MB. The new systems [Oxford 911 chip baseret] are supposed to 
offer over 40MB. If you don't know what bridge is in use, try a disk 
utility to test the throughput/speed of the drive. I use Formedia which 
came with my ClubMac drives. It's nearly identical to VST's software. 
They have an option for testing the speed of a drive." [Note: We have 
not checked this on our case as yet.]

Om de er bootbare på nyere Macintosh ved jeg ikke. Men de mount-bare

"...
Booting from a FireWire device:
Nearly all "onboard" FireWire equipped Macintoshes (except the Blue & 
White G3 and some early G4s "Yosemite versions") are capable of booting 
from a FireWire disk, provided that your Macintosh has ROM firmware 2.4 
or later. If your Macintosh ROMs are not 2.4 or later or you are unsure 
which ROM firmware you have, you should download the latest Apple ROM 
updater utility from 
http://docs.info.apple.com/article.html?artnum=75131
"...
Macintosh models which have FireWire disk devices connected to PCI 
FireWire adapter cards are not capable of booting. This is a hardware 
limitation, not a FireWire driver limitation.
In addition to your Macintosh's ability to boot from FireWire, the 
firmware on the FireWire bridgeboard (inside the drive case) must also 
have bootable properties. Unfortunately, some don't and no driver can 
resolve this limitation. If you are unsure, contact your FireWire disk 
manufacturer to find out if yours does.
