IT Person upgraded my PC, so he copy the data from my old hard disk (drive D) and install it in new hard.
But when he copied my locker file and i enter the password, i found that the file is empty and i don't have another copy from those data
The locker file was ECHO batch with the following command, so please help as unfortunately the IT formated the old hard disk also

cls
*ECHO OFF
title Folder Private
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Private "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to unlock folder
set/p "pass=>"
if NOT %pass%== password here goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:EndDo you mean to say that there was a hidden folder with data in it that didn't get copied across to the new hard drive?use this program on your old disk EaseUS Data Recovery Wizard 5.8.5 Thanks for feedback, but my old disk is formatted
So if i use EaseUS Data Recovery Wizard 5.8.5 will it back again my hidden locked data file?Generally when a hard drive has been formatted and a new os installed etc, trying to get data off of the old file system is like winning the lottery because new data overwrote the location on the hard drive where the old data resided. Data Recovery wizards are best when a file was just recently accidentally deleted and no new data was written to that space because the file is still there in that space, just with its first character of filename flipped to a ( E5h ) special character. http://www.diydatarecovery.nl/kb_undelete_article.htm

A data recovery service provider may be ABLE to retrieve fragments of what may be left by scanning the platters reading the magnetic signature to try to reassemble the prior data based on a technique that tests the strength of the 0's and 1's amplitude ( Magnetic Strength ).

Whereas:
If its a strong 0, then the prior bit was most likely 0 in the prior file system
If its a weak 0, then the bit may have been a 1 in the prior file system
If its a weak 1, then the bit may have been a 0 in the prior file system
If its a strong 1, then the bit was most likely a 1 in the prior file system

*This technique of reading the bit's signal strength is something that I haven't seen a piece of software perform, and you need a very expensive piece of data recovery equipment to perform.

*This is very similar to those who may remember buying blank cassette tapes and by example recording the radio to snag songs to add to mix tapes in the 1980s. When using a fresh blank 90 minute cassette your audio quality was as perfect as could be for whatever tape deck and quality of cassette you used. Upon the 2nd time recording overtop of the last recording of this music snag tape with new audio, if you have the volume up when LISTENING to this new recording and there is a dead area in the newest recording such as dead air or a pause before a commercial, you may hear the prior recording very faintly. The fact is that this is very faint across the entire tape and is the RESIDUAL magnetic signature of the prior recording. With the right hardware you could recover a good majority of the recording 2nd to last. Hard drives also share this characteristic due to magnetic recording and so with the right equipment to pick up on the signal strengths of each bit read, you can piece together within a pretty good amount of probability what the prior bit's value was 0 or 1. BUT this only works for magnetic media and will not work with SSD's and Flash Devices etc.Quote from: TY on April 17, 2013, 12:51:45 PM
