Unable to recover data from a dd image

[doglover04]

Hi long time ago one of my old hard drives went bad. Before i got rid of it i made a dd image out of the drive In testdisk i cannot recover the data it keeps saying file system is damaged from the dd image. I tried photorec but its not showing any of my files just all windows stuff witch thats not what was on the drive just a regular storage drive no windows on it. I looked all over on your forum. The dd image was created from testdisk. Am i unable to recover my data? I no longer have the drive.

Your drive could have gone bad because of unreadable sectors. DD is not the right candidate to handle read errors I suppose it stopped upon the first read error. I would always use ddrescue.

I tried photorec but its not showing any of my files just all windows stuff witch thats not what was on the drive just a regular storage drive no windows on it.

I have difficulties in understanding this sentence.
If I get it correctly you probably applied testdisk to your local disk but not to the dd-image.

Posting the logfile is always useful.

Your drive could have gone bad because of unreadable sectors. DD is not the right candidate to handle read errors. I suppose it stopped upon the first read error. To verify this: Your dd file should be as big as your bad drive.
I would always use ddrescue.

Ill try to explain it better. I right click on the dd image on my windows desktop and i select test disk and test disk opens and from there i have it scan for any data from the dd image but it keeps saying file system is damaged unable to repair from the dd image. Now i did the same steps for photorec by right clicking the dd image and selecting photorec. I did the same steps in photorec i did in testdisk but in photorec it keeps pointing to my windows drive drive C but it won't let me select the dd image within photorec. I hope this helps you understand what i mean. I can't post a log file no place to let me create a login file since its not the original drive just a dd image i created right before the drive died on me. In testdisk it saids filesystem is damaged cannot open. Bootsector and backup bootsector saids ok. I thought i could recover my data from testdisk using a dd image. I have read so many information on your page on how to recover data from a dd image.

Do it again using a command line as described by Christophe Grenier here:

If run correctly you should see an output like the one listed under "Extended DOS Partition Test":

I did the same steps in photorec i did in testdisk but in photorec it keeps pointing to my windows drive drive C but it won't let me select the dd image within photorec.

Use the command line as well.

If you do not manage to open up your dd-file, write that dd-file onto a sufficiently large empty harddisk and run testdisk again and navigate to the hard disk in question which now contains the content of your dd-file.
