-
- Well, a crash when writing to the hard drive is the worst case for any
- operating system. That said, I always explode stuff compressed with
- Zip type compression to the RAM: drive and then re-compress with LHA
- which is a bit more Amiga friendly, and in my experience gives better
- compression.
-
- The low level format of the disk is controlled by the controller on
- the drive (for SCSI drives) and a wayward program cannot affect that
- (the high level AmigaDos format is another matter).

- Ah, the disk validator will not validate the volume.
-
- Did you let FixDisk do a complelete cylinder for cylinder check of the
- disk? If fixdisk gets completely through the drive without finding
- any problems, then you should be able to tell it to re-validate the
- drive. If the drive is not validated after FixDisk gets through it,
- turn on the write enable switch from the FixDisk options menu, and then
- choose the validate disk option from its main control panel.
-
- DiskDoctor should not be used on hard drives, as it leaves them in a
- read only state anyway. Where does DiskDoctor move the error to?

-
- Well, out of 12 months of near continuous operation, I have never had
- a crash where I *had* to reformat the drive. Once I did have a sector
- that the controller thought was physically bad, but I just made sure
- it got allocated to a file, and then never deleted that file until I
- finally did get around to doing a full backup/restore of the drive
- (about 10 months later).
