Recovered wav files will only play first part, HELP!

[freedomRepo]

I am trying to recover some wav recordings that were on my laptop. They are GSM 6.10 wav files, (mono, 8-bit, 13kpbs). I had them backed up on a 128mb SD card as well, but I deleted them from that a few days before I lost the data on my laptop. I'm not sure how they got erased from my laptop either. It randomly powered off and when I rebooted, the files were gone. I am running a complete format search on the laptop hard drive as I type this. (the hard drive is hooked as a slave in another desktop running recover my files.) I hope that will turn up the files when it is finished. In the meantime, I have run the recover software on my SD card and I was able to recover the files off of that. The problem is, all the deleted wav files I was able to recover only work for the first few minutes of each file. After I start playing them, they sound normal for a few minutes (the files are about 3 hours long each) then it turns into this crazy garbled noise. Not static noise, but like electronic warbles. I have examined the headers on the wav files and they seem to be normal. Any help on how to better recover these files, or how to fix the ones that I have recovered or even any information on what could be making them sound like that would be greatly appreciated. My job may depend on it. yay.

Hi,

Focusing on the SC card first....

When you recover the files do they start with the names "Recovered......"? This is an indication that the file has been found by searching for its header and footer.

Because the files are so large, the are probably fragmented. This is why they play for a while and then you end upt with a chunk of unrelated data which is the white noise that you hear.

So the only way to track the fragmentation of the file is to recover the files using the file system records (ie. the FAT records).

You should try a Complete Format Recover of the SD card and check what results you get in Folder View of the results screen. Even better, would be to take an image of the card using EzyImage from www.getdata.com/download.php and we can get you to send us the image so that we can identify exactly what is going on.

Thank you.
