Ubuntu – Hard Drive error: bad/missing sense data

error handlinghard drive

I recently tried to check the spin down time of my hard drive with the following command:

sudo hdparm -I /dev/sdb | grep level

and got the error:

SG_IO: bad/missing sense data, sb[]:  70 00 05 00 00 00 00 0a 00 00 00 00 24 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

The drive reads & writes data just fine and mounts on startup as well. I just simply cannot run this command on this drive without errors

What does this mean, and how can I resolve the issue?

  • looks like your drive controller doesn't support that method of enquiry, not all usb sata chipsets are created equal. You don't say what model of drive or controller you are using so its hard to offer more advice here.

    You could test this by plugging into another usb controller or using a different drive with the same controller or better still direct via SATA.

    3TB drives can be too big for some usb2 era controllers so i would recommend getting a reputable usb3 sata bridge instead, it will be much faster as well.
