Partition space constantly miscalculated/missing in WinNT 4 Server (NTFS)

[ugh]

Hi folks,

I'm using a WinNT4 Server (SP6) on an old machine with 2 5GB HDD just for serving/file server purposes. Somehow after constant disk read/writes to a NTFS partition, the OS always miscalculates the free disk space on the partition. I'll have to run chkdsk /f on the partition to fix it all the time.

Anyone knows if there's a patch out there I can install to avoid this?

Thanks.
