pyjo i 've done the same thing. i tried to get some data using a recovery software. I have many .gz files, one of them is 12GB, but when i try to open them with WinRAR, it says that files are corrupted. I have not given up yet. if you come to a solution please let me know.

Dave, thank you very much for your advise. Few hours ago i visited again the customer and place the hard disk back to the DVR to try getting data out using the software (via ethernet) came with AVTECH but again with no result. "NO LIST DATA" So it's what your are saying that happened. Is there a software that can bring the hard disk to a previous condition? Where can i find a disk sector editor? Unfortunately, i've sent many e-mails to AVTECH about my problem and i've got no answer.

I have a very big problem with an AVTECH DVR, model AVC760. I have installed the above DVR in one of my customers. This was the myfirst DVR installation. Two days ago my customer had an incident and it was recorded in the DVR. Because i didn't know how to take backup from the DVR, i removed the hard disk from the DVR and i tried to put it in my desktop computer (WINDOWS) as a slave to access the files. Disk does not appear in "My Computer" , but i can see the disk in "Device Manager" and "Disk Management" although is recognized as an "Unallocated Disk". I realised that the disk was unreadable, unallocated because of a different file system so i put it back again in the DVR. That was it. The DVR was saying "NO DATA" when i was trying to search for the files and the available capacity of the disk displayed, was like there was no data. I have tried also to read the disk from LINUX and MAC OS with no luck. Does anyone, from experience, know a way to get the data from the hard disk?
