We have a RAID 5 array using Intel Matrix Storage (i.e. a motherboard based RAID). One of the hard drives has started to make a grinding noise, and the array is currently rebuilding.

We'd like to interrogate the S.M.A.R.T. values on the Seagate drives, but for some reason none of the programs we've tried have been able to read the S.M.A.R.T. values.

Is there any technique for reading the S.M.A.R.T. values out so we can tell which drive is on its last legs?

  • What programs did you try? – digitxp Sep 2 '11 at 15:06
  • HDDlife and AShampoo HDD Control. I think the problem is that all of the drives appear as one large drive thats 6GB in size (its RAID 5). Its almost like we need something to bypass the RAID controller and peer directly into the hard drive controller itself to work out which hard drive is on its last legs. – Contango Sep 2 '11 at 15:10
  • Most of the Smartctl diagnostic software for windows supports reading the smartctl of the harddrives behind the raid array. – Trevor Boyd Smith Sep 14 '16 at 12:42

If the Intel Matrix Storage Manager doesn't tell you about the drive's (SMART) status, then perhaps (or, as well) just use Seagate's (bootable) Seatools utility to diagnose the Seagate drives.

You simply have to set the BIOS from 'RAID' to 'IDE', and the drives should be visible as individual drives to the bootable Seatools media.

Once you've used it to diagnose the drive, turn the RAID back on in the BIOS and you should be back the way you were (RAID configuration will remain). At that point you can plan to swap the faulty drive (if needed).

    Thanks, good to know that this is possible. I'd be a bit hesitant to try this out - those RAID arrays are so fragile that if you switch the computer on with one of the drives unplugged, wait 30 seconds, then plug that drive in again, then switch it on again, it wants to do a full rebuild, which takes 10 hours. This should be totally unnecessary, as the drive was never written to. – Contango Sep 9 '11 at 16:10

In my brief reading, it looks like this may be a common issue with that controller. Try giving smartmontools a shot. It's supposed to have some experimental support for the Matrix controller.

2011-02-04: We added experimental support for disks behind Intel Matrix RAID driver on Windows. Please report your test results to the smartmontools support mailinglist.

Use /dev/csmi0,X as a device name to access SMART info of individual disks, e.g. like this:

smartctl.exe -a /dev/csmi0,0

  • Tried experimental support, it didn't seem to work at all. Thanks for the tip, anyway. – Contango Oct 29 '11 at 16:30

    Worked for me, Intel Matrix Storage Console, ICH10 chipset, smartmontools 5.43-0-20120-0620-r3567 – ChrisWue Jun 27 '12 at 21:20
  • +1 Worked for me, smartctl 5.43 2012-06-30 r3573, Intel P67 Express Chipset (6 Series PCH), iaStor.sys v (11/6/2010) (Intel Rapid Storage Technology). – Jonathon Reinhart Aug 28 '13 at 20:00
  • My array is for data (not OS) so had to use /dev/csmi0,1 etc, for other disks. Thanks. +1 – Felipe Alvarez Dec 23 '14 at 0:44

hddguardian works great with Intel Matrix RAID controller, essentially it's a GUI for smartctl.

  • This one's a winner for me. Argus Monitor was ok but hddguardian gives very understandable info about all the data and thresholds – nevster Jan 28 '15 at 10:20
  • Also works for my HDDs connected through the "LSI Adapter, SAS3 3008 Fury -StorPort". So, other RAID controllers might be suppported as well. – i3v May 10 '16 at 7:04
  • works for me as well. raid 0 ssd evo ty for software name – MonsterMMORPG Jun 27 '16 at 11:18
  • This looks great, but unfortunately the author received too many harassing complaints reported as "issues" and decided to shut the project down. – jimp Jun 5 '17 at 4:43

Argus Monitor shows SMART info for drives behind Intel Matrix RAID controller:

Version 1.8.17 (01/06/2011): Support for Intel Matrix RAID controllers (ICHx chipsets).


smartmontools worked well for me.

I have an Asus motherboard with Intel ICH10R RAID controller. Two of the HDs are in a RAID-1 configuration, and another 2 are regular non-RAID setup. I can query any of them with smartmontools.

The command line interface is pretty easy to use and can be scripted easily.

c:\>smartctl --scan
/dev/sda -d scsi # /dev/sda, SCSI device
/dev/sdb -d scsi # /dev/sdb, SCSI device
/dev/sdc -d scsi # /dev/sdc, SCSI device
/dev/csmi0,0 -d ata # /dev/csmi0,0, ATA device
/dev/csmi0,2 -d ata # /dev/csmi0,2, ATA device
/dev/csmi0,3 -d ata # /dev/csmi0,3, ATA device
/dev/csmi0,4 -d ata # /dev/csmi0,4, ATA device
/dev/csmi0,5 -d ata # /dev/csmi0,5, ATA device

This shows you the list of devices it detected. In my case, the 5 /dev/csmi0,x devices corresponds to the various SATA ports on the motherboard.

You can query any of them easily:

c:\>smartctl -a /dev/csmi0,2

ID #5 and #198 are of particular interest. There was an interest Google study that indicated they are somewhat good indicators as to when the drive is about to fail.


The smartmon tools worked for me as well, but only for the mirrored drives. Would not read the data from my Intel SSD... the Intel SSD Toolbox does this though.

  • Intel BX58SO motherboard
  • Firmware/BIOS RAID 1 (mirrored)
  • Drives: Seagate ST3500320NS
  • OS: Windows 10 64-bit

I also found that the AIDA64 software (formerly Everest) works. Easer to read than raw data, but this tool isn't free. Reads the S.M.A.R.T. data from both the SSD and mirrored spinners

As others have noted, the WikiPedia article on S.M.A.R.T. is well worth a read.
