2016-02-21 Disk Checking

Interesting stuff I need to remember when buying my next disk:

http://nilisnotnull.blogspot.ch/2016/02/what-to-do-with-new-disk.html

I have a SMART monitor for the laptop’s disk but the external USB disks don’t support it. As Peter says, though: “why did you buy it?”

For my Mac I still use SMARTReporter 2.7.1. Their website says the current version is 3.7.2 and that 2.7 is an “old and unnsupported version with less features” and “available for free and as open-source”. Oh well.

Their website

Using Homebrew, I just did the following:

brew install smartmontools
brew install gsmartcontrol

And for my external USB drives, I installed the OS X SAT SMART Driver version 0.8 because of what the README file said:

OS X SAT SMART Driver

Note for Yosemite (Mac OS X 10.10) users: Try first version 0.8. If it works for you, then just use it. If not or you want to try newer version or participate on development, then you must allow unsigned kernel extensions with command:
sudo nvram boot-args="kext-dev-mode=1"
  sudo nvram boot-args="kext-dev-mode=1"

The instructions are simple:

Sadly, my disk appears to be unsupported.

I used `diskutil list` to list the disks I have and `diskutil info disk1s2` which is my external harddisk:

...
   SMART Status:             Not Supported
...

DiskUtility identifies my external disk as “WD 10EACS External Media”.

For a short moment I thought that perhaps Peter’s reference to the `-d sat` option would fix it. He writes: «Notice that I had to use the “`-d sat`” option to tell smartctl that there’s really a SATA drive hiding behind all the USB stuff. (Took me a while to realize that I can do that, I used to think that SMART just doesn’t work at all over USB.)»

When I googled for the identifier of my disk, I found the following product listing: “Western Digital WD10EACS 1TB 16MB Cache SATA300 Hard Drive - New OEM w/1 Year Warranty”. It mentioned the magic SATA keyword. That sounds good.

But no such luck, apparently.

alex@Megabombus:~$ smartctl -d sat,auto -i /dev/disk1s2

=======> VALID ARGUMENTS ARE: ata, scsi, sat[,auto][,N][+TYPE], usbcypress[,X], usbjmicron[,p][,x][,N], usbsunplus, auto, test <=======

Use smartctl -h to get a usage summary

OK, so I wondered: is this SATSMART kernel extension working? Of course not.

alex@Megabombus:~$ sudo kextutil -t /System/Library/Extensions/SATSMARTDriver.kext
Password:

I checked back and found issue ​#39: Which version works under OS X El Capitan 10.11.x? The answer is: They all do, but you can’t install them from the driver’s homepage because it’s not *signed*. But you can download a signed copy from the website of DriveDx. There, they offer the same driver but signed. And so I uninstalled the stuff I had installed...

Which version works under OS X El Capitan 10.11.x?

alex@Megabombus:~$ sudo rm -r /System/Library/Extensions/SATSMARTDriver.kext
alex@Megabombus:~$ sudo rm -r /System/Library/Extensions/SATSMARTLib.plugin

And I installed v0.10 for OS X Yosemite 10.10+ from the External USB / FireWire drive diagnostics support page instead – and it works:

External USB / FireWire drive diagnostics support

alex@Megabombus:~$ diskutil info disk1
...
   Device / Media Name:      WDC WD10EACS-00ZJB0
...
   Media Type:               Generic
   Protocol:                 USB
   SMART Status:             Verified

Yay!

And my old SMARTReporter 2.7 is picking it up, too. This is great. 👍

But now, on with the tests Peter suggested. The short tests take a few seconds to run.

alex@Megabombus:~$ smartctl -t short /dev/disk0
...
alex@Megabombus:~$ smartctl -t short /dev/disk1
...
alex@Megabombus:~$ smartctl -a /dev/disk0

Oops, 4070 hours left for this laptop’s primary disk is *not cool!* Or is it the other way around? I guess “life time” is simply the *age* of the disk. In which case: no problem! 🙂

Time to run the long tests.

alex@Megabombus:~$ smartctl -t long /dev/disk0
...
alex@Megabombus:~$ smartctl -t long /dev/disk1
...

And now I get to listen to some audiobooks while the disks test themselves.

The result for the disk in the laptop:

alex@Megabombus:~$ smartctl -a /dev/disk0

I don’t think LifeTime counts down, AFAIK it counts up. My new disks started at 0 but YMMV.

Ah, that makes sense. Theses disks aren’t new. 😄

Some time has passed and I’m using a different backup disk (I store them outside our apartment). And it won’t mount!

No mounting of the backup disk means trouble.

I started the *console* app with which to log at the log files. After I plug the disk, it makes the usual noise and then I see the following:

OK, I’m going to try uninstalling the SATSMART kernel extension.

sudo rm -r /System/Library/Extensions/SATSMARTDriver.kext
sudo rm -r /System/Library/Extensions/SATSMARTLib.plugin

And reboot the system... I guess? Yes, a reboot is required.

The drive was left plugged as I rebooted and did not mount. When I power cycled the drive, however, it got mounted. So yes, SATSMARTDriver 0.10 interfered with this disk!

I’m going to try and install the 0.8 version of the driver...

And confirmed. This drive cannot be mounted with SATSMARTDriver 0.8, either.

Sadly, this does not mean that I can mount the first drive with SMART status enabled and the second drive with SMART status disabled. It means the second drive cannot be mounted *at all*.

I think I will have to get rid of this kernel extension – and get new disk drives, eventually.
