Development history
───────────────────
AMOS started as an idea. An idea of being able to salvage data that would
otherwise be lost. I thought this was a great idea, and contacted IBM for
some technical doc on HPFS. "The doc for HPFS is classified", I was told.
I was unable to breach this barrier (Does it have something to do with
Microsoft's rights on HPFS?), so AMOS is all my own work.
Without documentation, it is pretty hard to write a program for accessing and
even writing HPFS-drives. And very easy indeed to trash drives, making them
unreadable, OS/2 unbootable, and the like. Which is why AMOS has been such
a long time underway, and which is also why nobody but my beta-testers have
seen AMOS until this final v1.0 release.
I am pretty sure that no disastrous bugs remain, but nevertheless: Try AMOS
on your own machine, on a partition that contains data of which you have a
backup. Then, when you've seen that it works, use it on your 700MB data-
partition - but bear in mind that I have no responsibility whatsoever for
your loss of data. If anything goes wrong, pplease fill out the problem
sheet at the end of this text and send it to me - and I'll try to fix the
problem as soon as possible...
To make AMOS, hundreds of hours of work have been used. Most of the time has
been used in a sector-editor, trying to figure out the cryptic ways of HPFS.
Enjoy!
Release history
───────────────
v1.01 Released 2. dec. 1992.
Fixes minor bugs, mostly of cosmetical nature.
Added support for FREEspace mapping of FAT-drives.
This is an intermediate release, released instead of v1.1. v1.1
will include a FAT to HPFS file format converter, but I am having
problems with making it work in every case, so this is all you
get for now :-)
v1.0 Released 11. nov. 1993. First public release.
Features both HPFS read and write, but has no error correcting
facilities.
All basic FAT and HPFS manipulation routines are present.
Only registered versions have access to HPFS write routines.
