Overwritten file recovery

[cctvguardtech]

Hi, I have been having difficulties on retrieving the overwritten video files from the hard disk.

I have tried using ‘GetDataback’ software to recover the data but no luck.

I have also tried with ‘Glary Utility’ software but the software did not find my file that was overwritten.

I was wondering if there is any software or way to recover it back.

Thanks.

What do you mean "overwritten" ? With what? Same files ? Another files? Same sizes?
Which video files you need back (files format) ? What full drive's size and how many free space ?
Is it was some VR (video registrator) ?

Given the OP username and he is talking about video, I expect this to be a case of needing to recover cctv footage from the hard disk DVR, please correct me if I have presumed too much.

Ok, so your CCTV system has recorded an incident/event, but you havent gone to extract the footage quick enough and now the disk cycle has passed and the system has started to re-record footage over what you wished to extract.

In my experience CCTV systems use a variety of storage techniques, you will not get anywhere with GDB as they rarely utilize NTFS (I've never seen one actually), the vast majority I have seen write to disk in a raw format (maybe jpeg2000) or to ext/xfs file systems. It is also my experience that once overwritten, or that days footage is no longer available to the control panel for backup then you can forget recovering that footage.
