During installation of plan9, this problem caused making the backup copy of msdos.sys to fail. After installation, when I have done 'c:' and then do 'du -a /n/c:' I get a list of error messages. The 4608 seems to be the Trksize (= Sectorsize*Sect2trk from dossrv/iotrack.h). I found this in the source at The problem seems to be reproducable, i.e. repeatedly trying to get the wordcount of a file that showed the problem once keeps returning the error. Also, it reproduces for the same files over a (warm) reboot. It shows up, among other things, for some directories that (according to Linux 'ls') have a size of 4096. I can read those files/directories without problem using Linux. Is this a known problem? If not, is there any information that I could provide to help track down the problem?
