Access permissions denied to drive, ./reallmine trick doesn't seem to work as root

[soulbrix]

I've successfully installed this software, but I can't run it as root. Basically, if I run reallymine as a normal user, it says I don't have permission to access the drive, but if I sudo it, it says it doesn't recognize the command itself. I tried following the instruction to add ./ before reallymine, but it doesn't seem to work, but I might be doing it incorrectly. Can you help me with this? Thanks.

[themaddoctor]

You tried "sudo ./reallymine"? Did you remember that linux/mac are case-sensitive?

[themaddoctor]

Are you sure that sudo is actually installed?

[blonkm]

Try 'ls -al' to check that reallymine is really there. Try 'chmod +x ./reallymine' now run 'sudo ./reallymine' again

[andlabs]

./ only works if the binary is in the current directory; if not, you'll need to specify the path to it somehow.

[soulbrix]

Try 'ls -al' to check that reallymine is really there. Try 'chmod +x ./reallymine' now run 'sudo ./reallymine' again

I have this:

So, it doesn't seem to be there, but the command works by itself, as proven by typing just "reallymine" - it gives all the parameters it can take. I had a few issues installing go, as it didn't seem to install correctly. Had to modify the gopath. Do you think it may have something to do with that? I find it weird that it works without sudo, but then doesn't recognize it. I have a limited knowledge of this, ofc, but I was thinking that Go also has some kind of local vs universal user installation, as defined by the .profile file editing. I was wondering if that could also have anything to do with it.

[themaddoctor]

sudo runs something as root. root might not know about your GOPATH. So you are probably right, and need to set up the environment for root also.

[soulbrix]

Can you point me to the right direction in order to find info about this? Thanks.

[themaddoctor]

Not really. Log in as root and set up the environment the same way you did for ssantos.

[soulbrix]

I just created a new user and did everything by the book, but got the same error. I'm using Ubuntu, the latest version, if that affects anything.

[themaddoctor]

a new user is not the same thing as the root user.

maybe if you created a compiled ReallyMine executable, you could run it with sudo, and not have to worry about GOPATH.

[soulbrix]

https://medium.com/@patdhlk/how-to-install-go-1-9-1-on-ubuntu-16-04-ee64c073cd79 this was the guide I followed to set up Go.

I can try to create that complied executable, any guides I can follow? Thanks.

[themaddoctor]

I don't know. Maybe you can google it or someone else can help you. I have only done it once, and that was more than a year ago.

[soulbrix]

Somehow, I made it to work. At least, I think so. I tried running the command $ reallymine getdek /dev/sdb, is it supposed to take very long? Still testing if it is actually working, at least it ran on root, but I can't tell if the drive is spinning or just stopped.

[soulbrix]

Any information about this? I just need to know this so I don't waste 100 bucks on a 3 TB harddrive to get the contents from this one.

[blonkm]

I hope I remember correctly, but when I ran reallymine getdek it returned almost instantly.

[themaddoctor]

Which chip is on the bridge card? The OXUF and INIC chips often have the keyblock somewhere else and NOT on the user-readable part of the disk. Sometimes in the service area; for that, you need HDDSuperTool.

[soulbrix]

The board is a JMicron

[themaddoctor]

If it's a 3TB, try dumping the keyblock: sudo dd if=/dev/sdX skip=5860528160 count=1 status=none | hexdump -C where sdX is replaced with the name of the disk

[soulbrix]

It's a 2 TB, I thought of buying a 3 TB to extract it because I dunno if a 2 TB would work

[themaddoctor]

Then use the number 3907024928

[soulbrix]

Alright, thanks. Will it be quick? Just to gauge how long it should take when I do it.

[themaddoctor]

0.00001 seconds

[soulbrix]

OK, so I got this as a result:

[soulbrix]

Hello, guys. I have finally got a 3TB drive to do this, but I have one more question: do I have to reinstall ubuntu on this new drive in order to create the image, or can I use the previous installation and somehow redirect the image to the empty disk? Thanks.

[themaddoctor]

Run ubuntu from a live CD or USB.

[soulbrix]

Hm, didn't think it would be possible to install the apps there, but I'll try. Thanks!

[soulbrix]

I set it all up and let it run during the night, only to find out it gave a input/output error on the to be decrypted drive. Is it a sign the disk has problems?

[soulbrix]

Also, @themaddoctor, I saw on this other thread (https://github.com/andlabs/reallymine/issues/32) that it seems to be possible to just mount the drive without creating a whole disk image, did I understand this correctly? Thanks

[themaddoctor]

https://github.com/themaddoctor/linux-mybook-tools/blob/master/Mounting%20encrypted%20WD%20disks%20in%20linux.pdf

[soulbrix]

Ok, it stopped and gave the same error at the same file size, 3,2 GB. I'll try that method then.

[soulbrix]

I followed your guide. Went well up until the very last step, where it said it couldn't read the superblock. Do you know why this could be?

[soulbrix]

before, this is what was shown:

/dev/mapper/wd: DOS/MBR boot sector MS-MBR XP english at offset 0x12c "Invalid partition table" at offset 0x144 "Error loading operating system" at offset 0x163 "Missing operating system", disk signature 0x21365; partition 1 : ID=0x7, start-CHS (0x0,32,33), end-CHS (0x3ff,254,63), startsector 2048, 3497361408 sectors; partition 2 : ID=0x7, start-CHS (0x3ff,254,63), end-CHS (0x3ff,254,63), startsector 3497363456, 409595904 sectors

then, I get this:

test@test-Aspire-M3910:~/wd$ sudo kpartx -a /dev/mapper/wd
test@test-Aspire-M3910:~/wd$ sudo mkdir -p /mnt/wd
test@test-Aspire-M3910:~/wd$ sudo mount /dev/mapper/wd1 /mnt/wd
mount: /mnt/wd: wrong fs type, bad option, bad superblock on /dev/mapper/wd1, missing codepage or helper program, or other error.
test@test-Aspire-M3910:~/wd$ 

Got this with dmesg | tail: [ 1158.253759] print_req_error: I/O error, dev sdg, sector 6293504 [ 1158.253777] Buffer I/O error on dev dm-3, logical block 786432, async page read

Disks utility says that the disk contains a bad sector - should I run "fsck"? Will it destroy the partition or just some data?

[themaddoctor]

should I run "fsck"? No Will it destroy the partition or just some data? Probably.

You could try copying the disk (through the decryption filter) with one of the ddrescue variants. They skip over bad sectors in the correct way. Then do your data recovery on the copy.

[soulbrix]

The ddrescue is going now, running on /dev/sdg - since the layer is active right now, I figure it's still doing the recovery through the filter, right? Or do I need to set it specifically to dev/mapper/wd?

[themaddoctor]

Or do I need to set it specifically to dev/mapper/wd?

yes

[soulbrix]

aaah, this is driving me insaaane, it was at 35% after 16 hours. Alright, I'll change it to that drive.

I ***ed it up even more. I had 2 kernels but only one worked with the module, tried removing one using Synaptics, now the command to create the layers won't work and there is only a dm-0 device. Seems like it's a kernel issue. Will check if downloading the packages again fixes the issue.
