Fail at create wd-layer1 /dev/sdb

[awooooool]

when I try the "create wd-layer1 /dev/sdb" command, it says

"device-mapper: reload ioctl on failed: No such file or directory"

My drive is WD MyBook Essential 3TB with JMicron controller Any ideas? Thanks in advance

Edit: Now I got it to work, forgot to make the script in the appendix But when I try to mount it, it says

aulialuthfi@aulialuthfi-Lenovo-Y720-15IKB:~/wd$ sudo file -sL /dev/mapper/wd /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 0x246c6; partition 1 : ID=0x7, start-CHS (0x10,0,1), end-CHS (0x3ff,0,1), startsector 256, 732558080 sectors aulialuthfi@aulialuthfi-Lenovo-Y720-15IKB:~/wd$ sudo kpartx -a /dev/mapper/wd aulialuthfi@aulialuthfi-Lenovo-Y720-15IKB:~/wd$ sudo mkdir -p /mnt/wd aulialuthfi@aulialuthfi-Lenovo-Y720-15IKB:~/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.

any ideas? thanks in advance

Your partition table probably uses a different block size than your system. Try using the section about using a loop-back device.

Would you send me a copy of your keyblock, please?

[awooooool]

which one is the keyblock?

lemme try the loopback thing

Edit: Where should I put the keyblock?

Hi there,

I also stuck on when I try the "create wd-layer1 /dev/sdb" "device-mapper: reload ioctl on failed: No such file or directory"

[themaddoctor]

post your keyblock here so I can see what you found

That error could be because the rev16 module was not loaded, or /dev/sdb is the wrong drive, for example.

[fabianf83]

thanks a lot for ur fast help problem was that rev16 module was missing.

if I try to mount the wd i get this error root@ubuntu:/home/ubuntu/Desktop/cppi-1.12/wd1# sudo kpartx -a /dev/mapper/wd root@ubuntu:/home/ubuntu/Desktop/cppi-1.12/wd1# sudo mkdir -p /mnt/wd root@ubuntu:/home/ubuntu/Desktop/cppi-1.12/wd1# sudo mount /dev/mapper/wd1 /mnt/wd mount: /mnt/wd: special device /dev/mapper/wd1 does not exist.

Also the loop device wont work root@ubuntu:/home/ubuntu/Desktop/cppi-1.12/wd1# sudo mount /dev/loop11 /mnt/wd mount: /mnt/wd: wrong fs type, bad option, bad superblock on /dev/loop11, missing codepage or helper program, or other error.

normaly it should NTFS FS

my knowign is at the end now -.-

Send a dump of the first 2MB and I will look at it when I have some time. sudo dd if=/dev/sdb count=4096 out=dump.bin

Zip it and upload it here.

[fabianf83]

Thank u here it is

dump.zip

Looks OK to me. I decrypted it with the key that I extracted from your keyblock.

Okay, I dont Know what I made wrong. I rebooted and startet again. This time it was working. I can recover the Data now.

Just for ur information. With Ubunu I had problems with sudo apt-get build-dep linux-image-$(uname-r) GCC

both resources arn't available anymore. Thank u so much for ur help

[themaddoctor]

That's great. Glad it worked out.

Sorry it looked like I was shouting. Some markdown issue. I fixed my comment to be more friendly.

Could you add the version of Ubuntu you used? And the names of the packages that you did install? Thanks.

[fabianf83]

Ubuntu 18.04.3 LTS

bash GNU coreutils util-linux sudo cryptsetup (in Ubuntu, use “sudo apt-get install cryptsetup”) openssl file kmod or modutils are included in Ubuntu alreadz

kernel development (may be called “kernel-dev”) (in Ubuntu, use “sudo apt-get build-dep linux-image-$(uname -r)”)

$ sudo apt-get build-dep linux-image-$(uname -r) Reading package lists... Done E: You must put some 'source' URIs in your sources.list

GCC (the same version that was used to build your kernel) $ sudo apt-get install GCC Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package GCC

vim (for the xxd utility) multipath-tools git (to clone the repostitory) *not named in your documentation Need to install and there was no problem with installation

best regards Fabian
