RE: Cygwin 1.3.22-1 shows wrong disk space (df)


Oh yeah, sorry. Here is the cygcheck -s -v -r attached.
 <<cygcheck.out>> 
The C:\data is a native win2000 mount.

The fact is that df reports the wrong value for free space.

Some programs check for free space before writing a file and they
may decide wrongly if the free space is not reported correctly.

I don't know if df and other programs use the same method for
determining the free space. ( if df uses statfs(".",buffer) , 
then statfs is returning the wrong value for free space )

Regards,
David
