Quick update.I spent a lot of time hoping to not have to do the Chunk Dump of the RLL drive manually,
by trying a ton of software.
Basically nothings works on this 8088.
Testdisk was my last hope. But it wanted a 386 CPU, and didn't work.
http://www.cgsecurity.org/wiki/TestDisk_Step_By_StepSo got myself setup with
Norton Disk Edit and bunch of floppies.
It allows me to dump 1000 Sectors at a time (512 bytes per sector), which fit nicely into a 760K formatted 3.5" disk (writing to my External drive off the Bridbgeboard PC).
At the beginning (first 7 sectors) where the Hard Drive is corrupt, I learned when a Sector read failure occurs i(DiskEdit Tool) fills the missing locations with "00" which is perfect. (Everything is spaced properly in the image file)
It's working well, since the "Write-Image-to-Disk File" Tracks the last Sector I dump and next file dump starts off at next sector (1000 Sectors at a time).
Painfully slow, but working. I've done 10 dumps, 60 more to go.
Even slower since after ever few dumps, my old floppies die, so I picked out some of the best I have.
Once done,
I'll concatenate all the Mini Image dumps into One or two Image files (2 images: for both PC & Amiga Partitions), or (1 image: for the whole ALOK disk).
With these images on a Modern PC, I'll have many tools to try and extract the files. I can try many time without risk to original copy.
Either way, since I can't get the WD-RLL Controller to work in my 486 (which limits my tools to the 8088),
I'll do the Low Level Format of the RLL drive, and see what happens (
Hoping a reallocation of good/bad sectors restores the drive. I will be a few sectors short)
.If I manage to re-format the drive clean, then I'll have choices.
1) Build up a new setup (DOS and Amiga)
2) Do above but try to dump the Backed up Images back.
3) Somethings else
Stay tuned. I am running mini dumps, every time I pass by the computer.
