SMART Error: Unknown USB bridge



  • Hi,

    I've recently installed pfSense onto a new usb drive and everything appears to be working fine. However, Ive noticed the SMART status is now "Unknown" and upon running any SMART tests I receive the following error…


    smartctl 6.4 2015-06-04 r4109 [FreeBSD 10.1-RELEASE-p24 amd64] (local build)
    Copyright (C) 2002-15, Bruce Allen, Christian Franke, www.smartmontools.org

    /dev/da0: Unknown USB bridge [0x0781:0x5583 (0x100)] Please specify device type with the -d option.

    Use smartctl -h to get a usage summary
    –-----------------------------------------------------------------------------------------

    The USB drive in question is a "SanDisk 16GB Cruzer Ultra Fit" (USB 3.0)

    I can only assume this usb device is currently unsupported as its a new product from SanDisk. If that's the case would it be silly to wait and see if the next pfSense update supports this device?



  • Hi,

    You have to specify the type of device you are using. If -d test doesn't work, try some values (https://www.freebsd.org/cgi/man.cgi?query=smartctl&apropos=0&sektion=8&manpath=FreeBSD+10.1-RELEASE+and+Ports&arch=amd64&format=html), but my SanDisk is found with "-d scsi".

    smartctl -a -d scsi /dev/da0

    smartctl -a -d scsi /dev/da0
    

    Do you have the same USB disk as me?



  • @johnkeates:

    USB flash disks rarely have useful smart data, just ignore it.

    Is that a fact? Or simply your opinion? Sweeping statements like that can be dangerous for people that don't know any better.
