JPEG repair

[tomw]

Hello All,

I was able to recover thousands of JPEG files off a RAID 1 that went bad, currupted JPEG then copied them over to the second RAID HD. I copied them off before the drive failed completly.

I have searched the forums for previous people with the same problem and found two solutions below.

I tried running these through the software published by http://www.hketech.com/JPEG-recovery/, the JPEG are still fragmented, different color lines throughout them.

I also tried ppumpkin suggestion to open in ACDSee 3 and resave, no luck there either.

Should I consider these JPEG lost? Are there other ways that a data recovery service could use?

Sure it was Raid1 and not R0?

Sounds like the files were not copied off properly, due to the R0 not being reconstructed properly.

First of all, check what pcimage said, using a hex viewer, check if both drive contents are really the same.

Yes it was a RAID1 mirror. The drive had an error and I was prompted for I believe an integrity check or something, it was not a rebuild. I did that and everything was fine for a week so I thought no big deal. Then it happened again, I did the process again, took like 5 minutes to bring them back to parity and all files were fine, but I knew I needed to get the data off... I was slow about it. Before I could get it off it failed again, but this time during that rebuild process or whatever the drive failed about halfway through and I was left with two seperate drive letters in windows. I tried to use the raid tool to bring them back together but it failed and still two seperate drive letters.

This is where I copied the files off 1 drive that have lines and I am unable to repair. I sent the raw drives to a data recovery service and they were able to "image" the drives to pull data off, but these JPG also have lines through them.
