Initialized drive in Win 10

[Vasiboy]

Hi there I have a mybook 3TB drive with JM chip. I didn't realize they were encrypted, (to my detriment). I installed the drive to my windows machine and initialized the drive but didn't go any further.

I have taken the trouble of setting up an Ubuntu system to recover the info, and have followed your tutorial step by step so far so good.

The drive is plugged straight to the MB via sata cable.

I have typed the command sudo file -s /dev/sdc, but it comes up with (no such file or directory)

Do I have to mount the drive somehow using other software? Or should I plug it into an external enclosure?

I used Linux year ago, but always looking for challenges...

Any help would be appreciated. Thanks Vas

Command lsblk will tell you what drives are connected and what they are called.

[Vasiboy]

Hi Thomas thanks for the reply. I have moved further down your tutorial as follows: lsblk produces:

sda 8:0 0 223.6G 0 disk ├─sda1 8:1 0 1M 0 part ├─sda2 8:2 0 513M 0 part /boot/efi └─sda3 8:3 0 223.1G 0 part /var/snap/firefox/common/host-hunspell / sdb 8:16 0 2.7T 0 disk └─sdb1 8:17 0 16M 0 part

So after running all the commands in the JMicon section I have ended up with a hexdump for the Dek that looks like this:

00000f0 04 00 00 00 a1 00 00 00 97 00 00 00 37 00 00 00 |............7...| 00000100 44 45 4b 31 02 db 00 00 f9 a6 1c 19 8f 48 d8 78 |DEK1.........H.x| 00000110 ad cc 7b 12 d8 e5 ca 50 57 1d 65 39 26 1d 02 36 |..{....PW.e9&..6| 00000120 7f 75 4e 45 7f 37 6a fb c9 9e ec 8a 07 2e e4 8a |.uNE.7j.........| 00000130 bc 5f ba 05 00 00 00 00 00 00 00 00 00 00 00 00 |._..............

Does this look like anything that makes sense?

After doing the next couple of steps, I am now in appendix D, trying to build the cryptographic module.

The step that produces an error is the Build: make -C /lib/modules/uname -r/build M=$PWD

I get the message:

bman@BmanUbuntu:~/wd$ make -C /lib/modules/uname -r/build M=$PWD make: Entering directory '/usr/src/linux-headers-5.15.0-56-generic' arch/x86/Makefile:142: CONFIG_X86_X32 enabled but no binutils support make: gcc: No such file or directory warning: the compiler differs from the one used to build the kernel The kernel was built by: gcc (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0 You are using:

Please, what am I missing here and is that DEK hexdump any good?

Many thanks for your help.

Cheers Vas

PS I am working off a copy of the drive I made before doing any of this. I used DDrescue.

[themaddoctor]

You skipped some steps.

[Vasiboy]

You mean I skipped steps to get the DEK or in appendix D?

Ok thanks will go again.

Hi Thomas,

I read through again, and installed development packages for kernel 5.15.0-56-generic (my version)

I created a file rev16.c using text editor and copied the code contents into it.

Then I did the following steps as below but it came up with a different error:

bman@BmanUbuntu:~/wd$ echo "obj-m := rev16.o" > Makefile, (it created the Makefile ok)

bman@BmanUbuntu:~/wd$ make -C/lib/modules/'uname -r' /build M=$PWD

make: *** /lib/modules/uname -r: No such file or directory. Stop.

Help please? Thanks

[themaddoctor]

The left single quote mark is on the key to the left of the "1" key.

[Vasiboy]

Thanks again Thomas, now there is a message about "no rule" to make target?

bman@BmanUbuntu:~/wd$ make -C/lib/modules/uname -r /build M=$PWD make: Entering directory '/usr/lib/modules/5.15.0-56-generic' make: *** No rule to make target '/build'. Stop. make: Leaving directory '/usr/lib/modules/5.15.0-56-generic'

Getting there, cheers

PS reading through your steps again, I think I am working in the wrong directory whilst doing Appendix D ?? Should I be in: /usr/lib/modules/5.15.0-56-generic ?

I have looked at other tutorials online but still haven't joined the dots. Cheers Vas

[Vasiboy]

Hi Thomas, and Happy New Year.

I have got back to working on this drive, but still cant get past the last error message.

Can you help please?

Thanks Vas

[themaddoctor]

Send me sectors 0, 2048, 2049, and 5860528160.

sudo dd if=/dev/whatever skip=0 count=1 status=none | hexdump -C sudo dd if=/dev/whatever skip=2048 count=1 status=none | hexdump -C etc. I don't know what your "whatever" should be.

Do not post screenshots. Copy and paste the output into a comment.

Hi Thomas,

I did what you asked on both sdb and sdb1, many thanks.

These errors:

make: Entering directory '/usr/src/linux-headers-5.15.0-56-generic' arch/x86/Makefile:142: CONFIG_X86_X32 enabled but no binutils support make: gcc: No such file or directory warning: the compiler differs from the one used to build the kernel The kernel was built by: gcc (Ubuntu 11.3.0-1ubuntu122.04) 11.3.0

indicate that you have not installed the kernel development packages that are appropriate for your system.

This error:

make: *** No rule to make target '/build'. Stop.

indicates that you did not make the Makefile as instructed in the PDF.

The good news is that it appears that your filesystem was not overwritten when you initialized the disk.

Thanks for the reply Thomas,

I have watched a few tutorials, and installed quite a few packages (probably some not required).

I have followed the wiki.ubuntu.com/Kernel/Build/YourOwnKernel , and installed the packages as suggested there, is there another website you can advise?

The Makefile didn't come up with any errors at the time but I will try again.

Thanks for your time Vas
