I have a 540mb 2.5" drive from an IBM Thinkpad (DHAA-2540) that just won't work at all with 2.1 of an A600 nor with 3.0 of an A1200. It will appear under HDToolbox and I can get it to set up partitions. But then, upon warm reboot, no familiar icons for the partitions. If I click on the HDSetup program, the icons for the partitions will suddenly appear. I can then format these and install Workbench on the bootable system partition but after warm reboot nothing again. Very frustrating indeed. I've thought about cutting the first wire of the ide cable but never did because the cable cost more ($5.00) than the drive (free).
