UnFOUNDchk - Recover data from .CHK files
17.06.2023, 21:41 - Autor: Mark B.
As mentiond it's a ver bad idea to run
chkdsk on a drive when you plan to recover data! Good old HDDs would at least allow you to recover deleted data but this would be not possible on moden SSDs.
Another function of
chkdsk cause the tool to move and rename file into
FOUND.### folders. Hereby stand
### for a numerical value. This folders are then full with files named
FILE####.CHK which are very often fully functional files. So we loose often the context because filenames and folder-structures are often very important - e.g.
Analysis marketing data 2023-04 v3.xlsx would not just tell us what is the content of the file but also what version of the file we are dealing with and in case of
D:\Patients\2023\Joe_Black\X_Ray\IMG03765.PNG the folder structure would tell us to which patient the x-ray images belong!
Loosing that information may render data even unusable in extreme cases...
This is the reason why I strongly advice againce
chkdsk! In case your data got damaged by
chkdsk you can use the following free tool to revert the
.CHK files back into the original formats.
