Hi Matthew,

Have you tried teh tool as Byte has suggested? Please go to the following
link to try it:

Recover CHK Files
http://www.ericphelps.com/uncheck/

Note: The third-party product discussed is manufactured by a vendor
independent of Microsoft; we make no warranty, implied or otherwise,
regarding this product's performance or reliability.

You can also examine the contents of these files (found.000) with a text
editor to see whether they contain any needed data (if the converted chains
came from corrupted binary files, they are of no value). You can delete the
CHK files after you have saved any useful data.

IMPORTANT: Please do not run defragmenter since defragmenter will decrease
the opportunity to recovery the data.

Actually, Chkdsk scans and repairs volumes on the hard disk for physical
problems, such as bad blocks, and logical structure errors, such as lost
clusters, cross-linked files, or directory errors.

In addition, please know Microsoft does not provided data recovery service
and cannot guarantee the lost data will be retrieved.

Some repairs, such as correcting lost clusters (also knows as allocation
units) or cross-linked files, change a volume's file allocation table and
can cause data loss, Chkdsk first prompts you with a confirmation message
similar to the following:

10 lost allocation units found in 3 chains.

Convert lost chains to files?

If you press N, Windows 2000 fixes the errors on the volume but does not
save the contents of the lost clusters.

This is addressed in the following link with the snippet "Correcting
Problems by Using Chkdsk"

Please use a Hex edit tool to open these CHK files to find something useful
and post back if you have any update.

Good luck!
