Kindly guide me what software should I use for this process? I read in a thread on the same site already that it is a 4 byte signature on some off-set(which I can get from that thread again) and reset it to 0000 but I have not done this before so do not have much idea about disc-level editing. How can I reset that signature? The rough plan I have in mind is that I put another HDD in DVR and let it initialize it properly and then I bring that HDD into PC and see what signature is there and then overwrite the same signature on my original drive. OK, proceeding on the assumption that it has written the signature and hence rendering the HDD unrecognizable for the DVR. I believe that he didn't that's why I see no data. But the HDD before coming to me, was also with another guy who tried to recover the data and I don't know if he was smart enough the cancel it out. I really appreciate -> Yes when I placed the file in Windows PC, it did ask me to initialize and I canceled that out as I knew about the windows overwriting the signature. I have even tried VideoLAN VLC player but those file simply won't play.Īny assistance and/or guideline in proper direction is highly appreciated. I recovered few of these files on the PC and tried running them using every possible player out there. It shows me 166 files on it identified as SWF shockwave files ranging in size from 60MB-5GB each. Now I have reconnected the drive with the PC and ran some data recovery software on it. I have read few posts on this website mentioning the same situation where people have confirmed that merely attaching the HDD to PC will not wipe out the data. Then I put it back in the DVR and the DVR started showing Disk Empty message.
When windows asked to initialize the disk, I canceled out. I opened it up and connected it to a PC but it showed as empty with no data. Then as there is not DVD burner or any output component in it, I assumed I will have to take out the HDD to get the data off it. In fact, I played back and forth quite a few times and everything was perfect. Last time I checked I was able to play it back without any problem. I have AVTech AVC-770 with 120GB HDD in it. I have already searched high and low for the solution but no luck so far.
