Warning: DON'T USE DISKDOCTOR!
I recently tried using DiskDoctor with my A3000 hard disk under
WB2.0 to verify the data on the disk. Upon exit I found that my disk
was now hopelessly corrupted by DiskDoctor. It seems that DiskDoctor
found lots of keys unreadable. Now I know I should've used DiskSalv
to begin with but C= distributes DiskDoctor with 2.0 and you'd think
it would be safe to use!!! I guess DiskDoctor will always be one of
those files that you should delete from all disks.

I didn't use it to recover any information from the disk. I used it to format my new harddisk. For some reason FORMAT was unable to format my HD. FORMAT gave the message "Format failed - not enough memory", and that was on a machine with approx. 2.5 MBytes available. So, I would like to modify Dwight's warning a bit: Warning: DON'T USE DISKDOCTOR FOR DATA RECOVERY! >Dwight Blubaugh Ph.D. @ University of Cincinnati \_/ Mikael Karlsson, Lovsattersvagen 10, S-585 98 LINKOPING, SWEDEN V | micke@slaka.sirius.se | Absolut Software | micke@slaka.UUCP ~~~ | {mcvax,seismo}!sunic!liuida!slaka!micke

It cannot associate blocks with the correct header - so it resorts to first-come-first-served.. ie: makes a HUGE mess of your HD. I have had very favorable experiences with fixdisk with in-situ recoveries. But it is a little bit slow .. :-) It was only designed for up to about a meg or so. I was even able to recover the mess that diskdoctor made! Note that this was a repair, not salvage.. The drive was completely stable for about a week before I did a complete backup/format/restore. >>Dwight Blubaugh Ph.D. @ University of Cincinnati > \_/ Mikael Karlsson, Lovsattersvagen 10, S-585 98 LINKOPING, SWEDEN > V | micke@slaka.sirius.se > | Absolut Software | micke@slaka.UUCP > ~~~ | {mcvax,seismo}!sunic!liuida!slaka!micke -- Peter Wemm ------------------------------------------------------------------------------ wemmp@cutmcvax.oz.au (wemmp@cutmcvax.oz or ..!munnari!cutmcvax.oz.au!wemmp) "VMS is a text-only adventure game.

Fixdisk just re-creates the root-directory. I then go on as normal. Before fixdisk I had to try to salv my whole HD (Which wouldn't work on the old disksalv) (and)or start from scratch. > Peter Wemm > ------------------------------------------------------------------------------ > wemmp@cutmcvax.oz.au (wemmp@cutmcvax.oz or ..!munnari!cutmcvax.oz.au!wemmp) > "VMS is a text-only adventure game.
