- Now I have a problem, to which I know of *a* solution to, but I don't
- want it to be the *only* solution.
-
- Over the weekend I suddenly (well over the period of a few mins) lost
- 3.5Meg of my hard disc free space. I was archiving some files and what
- appeared to happen is that every time a new file was placed in the
- archive (producing a copy of the archive temporarily) the old one at
- the end was NOT being added to the free space map (or is it taken
- away?) on my IDE (A5000) hard disc.
-
- The consequence is that I went from 3.5meg free to zilcho all for a
- 500k archive. A further consequence is that *checkmap reports that the
- map is inconsistent with the directory tree.
-
- Now my question is, is there some easy way of getting that 3.5 meg
- back without having to re-initialise my hard disc and reinstal all the
- data?
-
- What I find hard to understand is that *checkmap obviously creates
- what it consideres to be the actual map of the disc during it's
- directory scan in order to compare it with what is stored as the map
- on the disc. So why then can it not just replace the disc map with
- this correct map?
-
- I guess there must be a reason, because in the review of the
- disc recovery program in a recent Archive magazine it states that it
- can't do any more than *checkmap does (or words to that effect) on the
- new map discs (ie. it can't recreate the map by scanning the disc),
- but I can't understand why this should be the case.
