What data? -- the original ntfs data or what Linux may have installed? I suspect that in either case it is now pretty much corrupted. The sembla= nce=20 of windows files will have a scattering of blocks over written by newfs. > > regards You seem to be confused with slices and partitions -- but it IS confusing. Just remember Microsoft partitions are slices in the BSD world. Malcolm
