Severe fragmentation of the MFT on NTFS volumes can cause this.  As
Cygwin tends to generate alot of directory entries and files for its
filesystem layout, this would be more pronounced there.  Try something
like Raxco Perfect Disk (its got a 30 day trial), and defrag your disk
completely.  See if it helps.
