Unable to unlock on Ubuntu 14.04

[RCheesley]

I've got this working on Debian but when I try to unlock on Ubuntu I'm having some difficulties.

I get the following when running the grep:

rcheesley@Puddle:~/wdpassport-utils-master$ dmesg | grep sg | grep "type 13" [756416.966932] ses 8:0:0:2: Attached scsi generic sg5 type 13 [756518.588560] ses 9:0:0:2: Attached scsi generic sg5 type 13

If I run the command manually to unlock after following all the required steps I get the following:

rcheesley@Puddle:~/wdpassport-utils-master$ sudo sg_raw -s 40 -i password.bin /dev/sg5 c1 e1 00 00 00 00 00 00 28 00 SCSI Status: Good

The drive is not available, however.

If I run the GUI I get the following:

Calling external cookpw-script... Sending SCSI commands to encrypt/unlock the drive... Secure Harddrive identified at /dev/type Failure while sending SCSI encrypt command -> Check if harddrive is connected properly! (Maybe /dev/type does not exist)

Could this be due to there being two entries returned with sg5?

Any ideas?

$ sudo sg_raw -s 40 -i password.bin /dev/sg5 c1 e1 00 00 00 00 00 00 28 00
SCSI Status: Good

Did you try to mount the drive afterwards? Like this:

# mkdir /media/wdpass
# mount /dev/sg5 /media/wdpass/

Try it.

[RCheesley]

I did try that, and I get: mount: /dev/sg5 is not a block device

[RCheesley]

Some more details if it's helpful, not sure if this might be a system problem rather than to do with the script itself.

Sorry, this isn't something I've seen before, as I don't run Ubuntu locally.

Could you post the results from the following on both systems:

• sg_raw -V
• verify md5sum password.bin (don't post the md5)
• sudo sg_raw -r 32 /dev/sg5 c0 45 00 00 00 00 00 00 30 both before unlock and after unlock.

[RCheesley]

Thanks for the help, really appreciate it!

On Debian Before mounting the drive:

SCSI Status: Good 

Sense Information:
sense buffer empty

Received 17 bytes of data:
 00     45 00 00 01 30 00 00 20  c4 eb 16 62 00 00 00 01    E...0.. ...b....
 10     30   

With the drive mounted:

sg_raw 0.4.3 (2011-02-25)

Password MD5 looks good

SCSI Status: Good 

Sense Information:
sense buffer empty

Received 17 bytes of data:
00     45 00 00 02 30 00 00 20  fb 8a 33 e7 00 00 00 01    E...0.. ..3.....
10     30   

When I run the GUI I get the following warnings (despite the drive unlocking perfectly fine) In the GUI:

Failure: udisk automoint didn't work! Maybe the uuid/Volume Serial Number you entered is wrong!

In the terminal where I launched the script I get the following:

Warning: Unable to open /dev/sr1 read-write (Read-only file system).  /dev/sr1 has been opened read-only.
Warning: Unable to open /dev/sr1 read-write (Read-only file system).  /dev/sr1 has been opened read-only.
Error: The partition's data region doesn't occupy the entire partition.
Cannot find device with major:minor 8:17: No such device

The drive has however fully unlocked and I can read/write all directories.

Will run it on Ubuntu later when I have a chance!

mount: /dev/sg5 is not a block device

Well, so it's actually a duplicate of #2. I have the same error, but it has nothing to do with ubuntu. I am using gentoo.

With the drive mounted:

So how did you mount it in the end?

[KenMacD]

Okay, that shows what it should, the drive goes from 45 00 00 01 (locked) to 45 00 00 02 (unlocked). I look forward to seeing what Ubuntu says.

[KenMacD]

@RCheesley As you're probably not also reading #2, try unlocking the device on Ubuntu, then run sudo partprobe, and take a look at your dmesg to see if a new drive like /dev/sdb has shown up. I'm thinking that I typically don't mount the /dev/sd* device.

[RCheesley]

OK will try this when I get home this evening, had not seen the other issue as the title didn't immediately suggest it could be related ;) On 25 Jun 2015 9:58 pm, "Kenny MacDermid" notifications@github.com wrote:

@KenMacD that's awesome, thank you so much!

I ran sudo partprobe after unlocking the device manually and it mounted immediately. Hurrah!

[KenMacD]

Great to hear. I added partprobe info to the readme in 788c00b40c087b6bd55f3cea3673f5204894efbb.
