Should be fine from a Syquest. It was - after I was forced into it! The 3400 refused to boot, giving a variety of errors - Type 10s, 'Chk's, just hanging ... All very odd, because it booted fine on Sunday and not on the Monday. No installations or system-type alterations in the meantime. Anyway, fortunately this was all two days after my SyQuest arrived, so everything was backed up. I thus reformatted the drive, created five partitions and copied the system back on, blessing it just by opening & closing it as someone suggested should work. Only ... the machine had suddenly turned into a 512. There was about a 1.5 second delay between clicking on something and the machine taking any action. So I called the Apple Helpline. 33 minutes of hold music later, I spoke to someone who knew less about partitioning hard drives than I do, and that's a pretty impressive achievement. She refused to escalate the call, saying calls on the 90-day free support contract are only dealt with on her floor. One call to Customer Services later and they agreed to put me through to someone who knew what they were talking about. Interestingly, this was not an Apple employee, but a dealer. Anyway, the upshot is that partitioning larger drives (mine's 2-gig) carries a significant speed-hit on the IDE drives used in PowerBooks. The Mac apparently has to search each partition separately everytime you double-click on something. It seemingly has no way of knowing that you've just double-clicked on something in partition 3, it checks the lot! The solution was to create just two partitions, a 100Mb one for all my tiny text files (lots of little snippits at 2k or less, which were talking up 32k blocks), and the other one for the rest of the volume. Apple also advised that there is a bug in system 7.6 which effects PowerBooks, and suggested I upgrade either to 7.6.1 or directly to 8. Oh, and my Internet sigs seemed to be the only thing I missed in the backup, hence the absence of any. Ben
