lshw -C disk reports incomplete firmware version

Bug Description

Binary package hint: lshw

I was able to reproduce this bug in both Ubuntu 10.10 and Ubuntu 10.04.1 LTS.

When getting firmware version information about a hard disk, the following command reports incomplete information:

sudo lshw -C disk

Here is example output:

       description: ATA Disk
       product: INTEL SSDSA2M040
       physical id: 0.0.0
       bus info: scsi@2:0.0.0
       logical name: /dev/sda
       version: 2CV1
       serial: CVGB036100TS040NGN
       size: 37GiB (40GB)
       capabilities: partitioned partitioned:dos
       configuration: ansiversion=5 signature=000daa5d

In the above output, "version: 2CV1" should have been "2CV102DH". In another system with a standard SATA disk (non-SSD), the version was also truncated by 4 characters.

This is very inconvenient when trying to determine if such a disk needs a firmware upgrade on a headless system.

Palimpsest (under (System > Administration > Disk Utility) reports the right information. See attached screenshot.

It seems lshw grabs its output from /sys/block/sda/device/rev.

I can confirm that lshw only shows the first 4 characters whereas palimpsest shows 8. These 4 characters are the exact same as found in /sys/block/sda/device/rev.

Scratch that. I've since found out that dmesg reports the right f/w version, palimpsest (which probably gets this via udev) inverts the last two characters. I've filed Bug #672764 about this.

palimpsest and
sudo hdparm -I /dev/sda | grep Firmware
SHows Firmware Revision: 100415
sudo lshw -C disk
shows in version only 4 chars
       description: ATA Disk

Confirmed on Ubuntu 12.10. lshw/udev truncates product model at 16 chars and firmware version at 4 chars.

$ sudo lshw -C disk | egrep "product|serial|version"
       product: INTEL SSDSA2CW08
       version: 4PC1
       serial: BTPR146100P1080BGN

$ cat /sys/block/sda/device/model

$ cat /sys/block/sda/device/rev

$ sudo hdparm -I /dev/sda | egrep "Number|Revision"
 Model Number: INTEL SSDSA2CW080G3
 Serial Number: BTPR146100P1080BGN
 Firmware Revision: 4PC10362

hdparm seems to be correct when printing Model as a 40 char string, Serial as a 20 char string, and Firmware as an 8 char string.
