- You might get checksum errors when switching from Amiga -> Blitz mode in the
- following fashion:
-
- (1) In Amiga mode, you begin reading or (more likely) writing a file, and
- while the computer is still flushing buffers you
- (2) Switch to Blitz mode, thus killing the OS, including disk activity, thus
- creating a damaged block(s) on the device still being used.
-
- To the avoid this problem in the future, you should wait before entering Blitz
- mode until all disk activity stops. Since there is no way of knowing this via
- the OS, most programmers simply pause before they shutdown the OS for 3-5
- seconds. This provides sufficient delay for disks to stop spinning. I
- suspect that reading the Blitz manuals would have told you the same thing.
-
- To (attempt to) repair the damage you have caused your hard disk, you need a
- disk repair program such as the popular DiskSalv. If you know a lot about
- disk structure and the contents of any file(s) that were destroyed, you could
- also attempt to do this yourself with a disk editor. If you have an earlier
- version of the OS, you might have diskdoctor in your C directory. Delete it.
- You're better off getting one of the many freeware/shareware programs out
- there such as FixDisk or the already mentioned DiskSalv.
-
- Hope this helps,
