Is there a way to diagnose a tar file when, on extract, files are missing but no errors are given?
I know this is a bit obvious, but could any of the extracted files be hidden?
Have you tried just listing the contents of the tar prior to extraction?
Which platform are you taring and where you are extracting. If you are taring in Linux and untaring in windows then you might find unusual behavior due to long filename. did you do a tar -tvf 365.tar against the ls -lR 365 and see if that matches.
tar -tvf 354.tar > 1.log
ls -lR 365 > 2.log
diff 1.log 2.log
does the above helpful.
