Reallymine can't find key sector if it encounters bad sector?

Open jgan96 opened this issue 8 years ago • 7 comments

If Reallymine encounters a bad sector when searching for the key sector on a disk, it seems to return "key sector not found" instead of skipping over the bad sector. I have verified that my disk has some bad sectors in the beginning, but the key exists in mod 0x25. Any way to manually input the mod or set a flag to skip bad sectors?

That's strange; I thought a bad sector would result in an I/O error, but I guess not?

I need to add options for specifying key sectors from an alternate source. I already started working on code to extract the mods directly.

You are correct, I believe the issue originally was the USB to sata cable I was using wouldn't let me read all areas of the drive or something like that. I switched to a desktop machine with an internal sata port and it found the keysector fine, however I am now getting I/O error when I try to run decrypt. Is there any way around this?

For now I just ddrescued the drive and it seems to be able to decrypt that one. If it doesn't complete though I will post the results.

What is your ddrescue log file?

I believe this is it. I made the clone a couple weeks ago so not 100% sure. 16049.zip

Yep, you have quite a few bad sectors early on in the drive. We'd have to know what the partition layout is (if this isn't a single partition's image standalone) to find out which files are lost in that, unless you want to try running ddrescue again (using the logfile to tell ddrescue what it already did).

I tried to run Reallymine by booting the mac with a Ubuntu CD live.

I installed Git, GO and Reallymine; however, when I try to use it it tells me that it cannot be found.

I search for the file with the name reallymine (and any other variations) and I can't find it. Its not clear where its being saved.

If anyone knows, please let me know.
