Ooops. The ASDG part was copied from my preceding mini-review of the ASDG product and I forgot to change the name. The $900 was not a typo. Got mine from HT Electronics in Sunnyvale. Where did you get yours for $750? By the way, I just spent the last 3 days recovering from a scrambled disk. This could have happened on ANY hard disk, so it's not really a CLtd comment. Was running a program that had several files open on the hard disk and was actively writing to it when it GURU'd. Bye bye disk structure. I did find out that diskdoctor does NOT fix, or even necessarily find, all filesystem problems. It ran for a while, grumbled about some things it found, asked if it was ok to delete some corrupted files, and then exited with the suggestion to copy my files to another disk and reformat this one. Well, apparently something it does as it is exiting causes the disk validator to run, which was failing with some message about Key xxx already set. I spent most of new-years day writing my own version of a filesystem consistency checker, with emphasis on the consistency of the keys. It ran fine on floppies or on ASDG's recoverable ram disk, but I couldn't get it to run on the hard disk. Does anyone know what a return of -3 from DoIO() means? Anyway, luckily I had just done a full backup of my disk with bru about 4 days before, and the rest of the files that were newer than my backup, except for one, were all readable, so I was able to reformat the drive and recover, with the loss of only a single file. Bru (Backup and Restore Utility) is a program I wrote for my Unix system about 4 years ago, after taking one look at tar, cpio, volcopy, dump/restore, etc and saying "yuk!". I did a quick port to the Amiga about mid-December. The Alpha 1 version of bru is freely redistributable and will appear on one of my next disks. It is also available on the Software distillery and on BBS-HT (HT Electronics' BBS). It is the last freely redistributable version as I intend to eventually make it a commercial product. So, the question is, have you backed up your hard disk today??? -Fred -- =========================================================================== Fred Fish Motorola Computer Division, 3013 S 52nd St, Tempe, Az 85282 USA {seismo!noao!mcdsun,hplabs!well}!fnf (602) 438-5976 ===========================================================================
