I have a hard drive that began to fail recently, throwing errors and failing to mount any of its partitions. I used the amazing
ddrescue tool, running in Debian, to recover the main three partitions from it. All three are NTFS partitions and in all three cases
ddrescue was able to recover the vast majority of the data. But in all three partitions, it also indicated that some data was lost to errors:
- Partition 1: Size: 57 GB,
errsize(from ddrescue): 8KB
- Partition 2: Size: 110 GB,
errsize: 40 KB
- Partition 3: Size: 95 GB,
errsize: 14.6 MB
All three images mount normally and seem to be accessible.
My question is: I don't know where these errors are in each image, and I don't know which files are damaged. Would it make sense to run
fsck on these images to correct any inconsistencies? Or might that screw things up further?
