:
way,
An early UNIX paper shows the system had four
RK05's (4872 512-byte
blocks on UNIX, for some reason only 4800 used on the DEC OSs ...
remember we had to poke ROLLIN to copy the full UNIX partition
standalone).
Bad blocks? I think I have an article in AUUGN where I proposed that bad
blocks be assigned (somehow) to a pseudo-file as inode #0 (or -1?); that the "dump" utility would not see it, and
neither would the FS tools (but a
disk
image would, of course).
No, not to my knowledge. The DEC drivers just left off the last 72
sectors. There was no provision using them for block replacement.
The utilities just stopped at 4800.
