Yesterday, when I tried to restore a Nandroid backup in Ra_hero 1.6.2 recovery, the process failed. After checking the recovery log, I found that the system stopped the restore process because the data.img md5 checksum is mismatched.

I then cross-checked the md5 of that data.img with the one in the nandroid.md5 in my PC and found them to be different. I then created another nandroid backup and the md5 is also mismatched.

There's no error message during the backup process. Anyone knows what's the problem?
