Excuse me hddlab, to search ".dat .mpg .mpeg" from where?

If you searching for the text line that ends with ".dat" or ".mpg" or ".mpeg" from a file list:
grep -E "\.dat$|\.mpg$|\.mpeg$"

please give more details
Best Regards

Here is a windows tool that can search for hex strings in file headers, assuming that's what you really want.

Gsar for Windows:
http://gnuwin32.sourceforge.net/packages/gsar.htm

"gsar (General Search And Replace) is a utility for searching for and --- optionally --- replacing strings in both text and binary files. The search and replace strings can contain all kinds of characters (0--255), i.e. Ctrl characters and extended ASCII as well."

IF:

1- the hdd is in good condition ---> no need to waste your Ferrari on such a task - use any App.
2- bad condition ---> clone it or dump the image and refer to option 1

good luck

Thank you labtech, einstein9 and hhddrec for your reply.
einstein9: I like you said: the "Ferrari"
To everyone: my HDD is good condition but it come from 8ch H.264 Standalone DVR System and the system use different method so when we plug the HDD in to a PC, all the data gone. PC3K have protected mode and I hope it don't do something stupid like Windows

searching for Movies saved is a waste of TIME,

All DVR`s uses RAW Special Recording method, which is NONE STANDARD (in some cases)

i guess that BlackST has some idea`s here about DVR but thats not gonna be cheap (i think) and depends on DVR type

good luck

Show us the contents of sector 0. That may tell us if the data are encrypted.

BTW, AISI, if Windows doesn't understand LBA 0, then there would be no reason for it to touch that sector. I could be wrong, though.
