It sounds like you are running an old dossrv.
Either update your system to the latest update,
or change devio.c thusly:

diff /n/dump/2000/0601/sys/src/cmd/dossrv/devio.c devio.c
38c38
< 	seek(xf->dev, xf->offset+addr*Sectorsize, 0);
---
> 	seek(xf->dev, xf->offset+(vlong)addr*Sectorsize, 0);
57c57
< 	seek(xf->dev, xf->offset+addr*Sectorsize, 0);
---
> 	seek(xf->dev, xf->offset+(vlong)addr*Sectorsize, 0);

and recompile dossrv
cd /sys/src/cmd/dossrv
mk install
mk clean
