Well, the tracker entry is 28 days old, this discussion is 12 days
old, and ... this is not the first time I have to whine about the
"user base" of FreeDOS, if such a thing exists at all. At least, this
time the BUG got opened by http://sourceforge.net/users/tnavratil/
Tnavratil, not me.
So new results:
- To reproduce this BUG, following "might" be necessary:
- - 2039 kernel (but no final evidence that 2038 is NOT affected)
- - FAT28
- - 6 GiB volume
- - 4 KiB cluster size
- - Disk almost full (>95%) OTOH no need to fire "disk full" ERROR
- - Free space heavily fragmented
- - Copy (COPY) some (many ? >> 10 ?) files onto the volume, kick a
few (DEL) of them, copy some (many ? >> 10 ?) more
- Result: horrible mess. Many bunches of crosslinked files, per 2 or more
"members", "usually" icluding 2 files copied just atfer each other or
almost, but also "old" files (properly defragmented to to begin of drive
before) are included and corrupted. Cluster chain missmatching directory
entry size. Lost cluster chains.
- The INTERESTING THING is visible inside the directory: all the "evil" and
"new" files, whether crosslinked or not, have the UPPER 16 bits of STARTING
CLUSTER ZERO !!! This is illegal, since there was > 256 MiB ( 4 KiB * 64 Ki )
of compact space occupied before the test !!! So the 2039 kernel FORGETS
the upper 16 bits at some time and starts WRITING INTO the OCCUPIED
area at the volume start, corrupting the files hanging there !!!
Well, I invested a considerable amount of time into investigating this BUG,
and caused a considerable data damage, there is no doubt that the 2039
kernel has a CRITICAL BUG ... what now ??? Are there really only 2 users
who complained so far, within 4+1/2 months after the kernel release ?
Anyone is able to fix it ?
