In an earlier posting, I mentioned that the Assimilation Process ramdisk software uses a "belt and suspenders" approach to avoiding ejection. It marks itself non-ejectable (by tagging its drive queue entry), but will also re-mount itself if you eject it (by clearing the tag in the drive queue, for example). I wondered why the author bothered. Answer: because some programs don't care if the disk is marked non-ejectable. ResEdit, for example, doesn't hesitate a moment to throw out a supposedly non-ejectable disk. I should check to see if the standard file dialogs respect the flag; I wouldn't be surprised if they don't. On the positive side, the hardware for which I'm writing this ramdisk is progressing nicely. Yesterday, we had the ramdisk running with both an additional half-meg (1 meg total) and an additional full meg (1.5 meg total). It was a real pleasure to see "512K in disk; 518K available" *and* have full "Fat Mac" heap sizes. For example, I can open a fair-sized MacDraw document from the desktop and be ready to edit in <10 seconds. *****Not exactly a disclaimer: This hardware/software will be available through Mass Tech Development Labs. I'm not a Mass Tech employee, but I am writing the ramdisk software for them. (They're all hardware types.) I know nothing about pricing, availability, warranties, etc. I can only certify that the hardware is real. They supposedly have an ad in the current MacWorld; see that for their address and phone number. -- Ephraim Vishniac [apollo, bbncca, cadmus, decvax, harvard, linus, masscomp]!wanginst!vishniac vishniac%Wang-Inst@Csnet-Relay
