After I had linux complain at me during a file copy onto a ReactOS
partition, I checked it with dosfsck, and found all some issues.
Since then I have been checking the partition I use for vmware after
installs. dosfsck has been finding errors every time. I ran a quick
regression test and it seems the was introduced between 0.2.8 and
0.2.9. It seems that most of these errors are non fatal, as myself
and others have not noticed this causing any problems. Still, it
bothers me, since it could be causing a problem somewhere. GreyGhost
claimed Windows was not finding any issues with his ros partition, can
anyone confirm?
I'm using flat disk images under vmware and qemu, and I'm seeing this
issue under both. I'm using both IDE and SCSI drives under vmware,
and see the issues with both types.
Anyone who is more famliar with filesystems care to comment?
