Permission denied when reading keyblock #10

Open bronsonj opened 6 years ago

bronsonj commented 6 years ago

Hi Thomas! I found this via the WD forums. I've been reading your pdf file and trying my best to get this to work, but being a completely new to linux, I seem to have missed something somewhere. When I try to read the keyblock, i get a message saying permission denied in terminal. I have a SW6316 chip if that helps, and I never applied a password when I used to run the hdd in its original enclosure. I would really appreciate if you could lend me some of your precious time to help me out.

PS. terminal says the following; dd: failed to open '/dev/sdb'; Permission denied

Put "sudo " in front of the command. Note the space. It will ask for your admin password, so that it can access the raw disk (normal users are not allowed).

Thanks! Everything was fine, until I tried mounting the drive. I keep receiving the following message;

mount: you must specify the filesystem type

After researching the net, I tried "sudo mount -t auto /dev/mapper/wd1 /mnt/wd" but I keep getting the same message. I also made sure that the NTFS drivers are installed. Any idea what could be the issue?

Did you use kpartx or the loop method?

Send a dump of the first 2MB of the drive as seen through the filter (/dev/mapper/wd) for me to look at.

sudo dd if=/dev/mapper/wd count=4096 of=dump.bin

Or try -t ntfs-3g in the mount command

I tried the kpartx method first, but i got the message:

"mount: you must specify the filesystem type",

so then i tried the loop method, and I kept getting the same message.

I haven't had the time to try out your latest suggestions, will update once I get around to doing this.

Thank you again for taking the time to help me out, it means a lot. Cheers.

I gave a shot with the "-t ntfs-3g", but i still get the "you must specify the filesystem type" message.

I've attached the dump.bin file, but had to rename it to .txt, since .bin files aren't allowed.

dump.txt

You have an NTFS filesystem starting at block 2048

themaddoctor commented 6 years ago

You haven't responded. So I suppose you used a loop device as described in the PDF.
