Get Data Back corruption

I am attempting to recover data from a damaged hard drive using GetDataBack for NTFS. A friend was able to connect the hard drive and extract most of the files but a number of them seem to be scrambled beyond use. In particular excel sheets and zipped folders are the biggest victims so far.

Does anyone know if there is any reason to believe re-running GetDataBack would help? Or are there other options that might better luck? I have tried a couple file repair tools on the individual files with no success so any other thoughts would be appreciated.

Thanks.

 

Hi giz,

ZIP files are very 'sensitive'. A simple alteration of a ZIP file (during a downloading for example) ends often with a CRC error message and the extraction is impossible.
If a non password protected ZIP file contains only multimedia files in compressed format (JPEG, MP3, AVI, and many others), it's possible, with a good hexadecimal editor, to retrieve a few of them. Therefore, you must know the specific header and the file description related to their format.

 

Hi Chicon,

The one zip file is full of fonts from a large collection I purchased, is that something that could be salvaged? Is there an article I could read on how to use a hex progam to do that?

Thanks.

 

Hi giz,

I have just made a test with font files (.TTF and .FON). They are highly compressible in ZIP file (compression rate around 55%).
Unfortunately, in your case, there is no way to get your fonts back.
Even with an hex editor, you won't be able to extract them because the algorithm used to compress files is very intricate even for programing experts.

 

Thanks for your efforts all the same Chicon. I guess those are gone-zo. Oh well.

 

Have you considered trying another File Recovery program? My Hard drive has crashed several times before in the past and I was able to recover 100% of my files each time. I use Easy Recovery Pro software and it is the best. I tried at least 3 other file recovery programs and while they did work, not one of them was able to do a complete recovery like Easy Recovery Pro. As an added bonus, Easy Recovery Pro has built in repair utilities for ZIP and MS Office Files (Excel, Word, Access, Powerpoint)

Wow, thanks Rollin, that could really help me out. I'll look into it for sure.

 

Another good program that the professionals use is Acronis Recovery Expert Deluxe. It has two different scanning modes, a fast one and a slow one. The slow one checks each and every sector of the hard drive, and while it does take a long time, it usually finds files that other programs miss. Hope it helps
