SUMMARY
When copying a file from a Macintosh client to a Windows NT Advanced Server
Macintosh volume that is larger than two gigabytes (GB) in size, the file
size is displayed incorrectly.
For example, a 12 KB file will appear as 11,176 bytes (because of the
difference in disk formats) on the Windows NT computer and -1,721 bytes on
the Macintosh computer.
MORE INFORMATION
This problem is caused by the Macintosh Finder. The Macintosh Finder was
designed to handle volumes less than 2 GB and assume that the free volume
space plus the used volume space equals the total volume size. Because of
this, Windows NT Advanced Server reports file information to Macintosh
clients through a filter. The filter reports that the total volume size and
the free space on the volume are 2 GB if either is larger than 2 GB. In the
case of the problem above, Finder attempts to reconcile and report the file
size information based on the assumption that the total volume size is 2 GB
+ 12 KB.
