References: I just recovered from a hard disk crash and I thought that how I did it might help someone else in the same fix. Pardon the length and details if this is a trivial problem to some of you. I was using Packit II to unpack a file that binhex had reported a crc error on (I know, I know, but sometimes it is a small doc or source file that is munged and some of the packed files are still usable). Packit complained that the "packed file is bad" and then while the finder was restoring the desktop windows a system error 02 (unrecoverable restart) occurred. On reboot, the error continued to occur whenever the desktop was beginning to come up. I tried to make a new desktop (holding control & option down while booting) but a system error (02) occurred again despite this. I then used "Disk First Aid" (the program that Apple distributes) which reported that the SCSI needed repairs. It repaired it, but when I rebooted, the dialogue "SCSI needs minor repairs" came up and if repair was selected, a system error (28) was generated. Thus it appeared that I was stuck. Solution: I put my HFS backup program (commercial HD backup program) on a system floppy and booted from that with the initial desktop window open showing the HFS backup icon. There is a delay of about 0.25 seconds between the time the floppy desktop appears and the appearance of the dialogue box which asks if the SCSI should be repaired. During that time, if you can double click on the HFS backup icon (takes some practice) the backup program will execute and was fortunately able to read the SCSI directory and backup th

( the author goes on to explain a long procedure of saving his disk) I ran into this problem some time ago. The problem seems to be that while PACKIT is restoring the file it finds some problem with the packed file and leaves a file on disk which has funny resource information. This caused the finder to barf when it was trying to read the resources necessary to display the icon. My solution was very simple. Create a system which has a desk accessory which allows you to delete files. There are tons around in both the public domain and commercial products (DiskTop from CE software looks pretty good, Q&D Utilities Vol1 has a nice tool: Q&D Filer). Put this system on a floppy disk and boot directly into an application which supports desk accessories using SetStartup. If you boot up with this system disk then your HD should be mounted fine and you can use the DA delete feature you installed to delete the offending packit file and the new file which was created. Quit to the finder and all should be OK. This is much less time consuming and it seems to me to be safer than the other procedure proposed. The best thing to do if you find that 'THE PACKED FILE WAS BAD' is to delete the files from within PACKIT (which has a delete file menu selection) so you don't end up in this mess in the first place.
