Hello all, DISCLAIMER: I have only minimal understanding of DOS internals, so don't count on what I write being accurate; it reflects a year of superficial reading. Anyhow, I would never see the bug DOS386 mentioned because 1. I haven't used that much space; most of my DOS drives are <2 GiB 2. I generally use another OS for copies-I can't use NTFS, network, or my USB2.0 flash drive (unless booted from it), and my laptop lacks a floppy drive 3. I mostly use FAT16
I guess the BPB/DPB is a drive structure so not at fault, FCBs are (?) not used for copying; thus I would expect that the issue might be in the FAT32 code, ints used for copying/deleting files, fnodes, SFTs, or some such part of the kernel. Based on this guess, I looked over the revision list (http://freedos.svn.sourceforge.net/viewvc/freedos/kernel/trunk/?view=log) and came up with some revisions that might be worth checking: 1448 -FAT32 cluster optimisations 1437 and perhaps 1436 1408 1397 Of course, this is just based on 'ASSuming' that 2038 does not have the bug, and that changes in the fnode/SFT structure or FAT32 clusters are the most likely cause. Are these reasonable guesses? Another guess: Somewhere, the code might use a short int where it should use a standard int, since " all the "evil" and "new" files, whether crosslinked or not, have the UPPER 16 bits of STARTING CLUSTER ZERO " @DOS386: I noticed a comment to the effect that you don't know whether 2038 has the bug. How much have you used/tested 2038 (i.e., how likely is it)? Sorry for the long post.
