Chkdsk turned all JPEGs into .CHK files

The other week I received a SD memory card on which chkdsk was automatically run. Chkdsk turned all JPEGs into .CHK files. When Chkdsk removes certain files from the file system, it saves the content of the clusters that belong to the file in .CHK files. They are typically written to a folder called ‘FOUND.000’.

Why photo recovery and undelete software recover corrupt jpeg files.

Free File Recovery and Undelete Software

Is file recovery from a SSD (Solid State Drive) possible? As more and more PCs and laptops are shipped with a SSD drive this question becomes more relevant.
