Because I had some problems with my server I want to check it's hard drives for defects (the drives not the file system) which tool can I use for this in ubuntu?

I know for my hard drives there is a CD from Western Digital (Data Lifeguard) but I can't get it to run via usb CD drive. So are there any native alternatives?

System Information:

  • Acer easyStore h341
  • Intel Atom D410 1.66GHz
  • 2x 1TB Western Digital Caviar Green (WD10EADS-00P6B0)
  • 2x 1TB Western Digital Caviar Green (WD10EADS-22M2B0)
  • RAM 2GB

If disks support SMART, you can try smartctl (from package smartmontools).

sudo smartctl -d <ata,scsi, etc... > -H /dev/sd*

In addition to (not instead of) smartctl, or in the unlikely event that the disks do not support SMART, you can test the drive for physical/magnetic damage using the badblocks utility.

  • Does this really check the disk or just read the SMART status? Because the SMART status can be fine even though the drive isn't working properly. – K. Hendrik Nov 16 '11 at 20:44
  • only smart tests will be done – Bruno Pereira Nov 16 '11 at 20:49

    badblocks looks like the tool i was looking for thank you! – K. Hendrik Nov 16 '11 at 21:00
  • the command above only reads the SMART status, but the tool can perform tests to hd too. Check its man page, specially the -t switch. – Salem Nov 16 '11 at 21:03
  • Or you can use the gui disk utility to run the smart tests. – psusi Nov 16 '11 at 21:21
