Description

There is Genesys Logic, Inc. USB 2.0 IDE Adapter (ID 05e3:0702) described in wiki, that it is unsupported, and link to the mail archive.
Ok, but why is it unsupported? There is no information in wiki. Is it impossible to add its support? I was reading datasheet http://www.datasheetcatalog.net/de/datasheets_pdf/G/L/8/1/GL811E.shtml
And found that this bridge complies with ATA/ATAPI-6 specification rev 1.0, and ATAPI-6 includes S.M.A.R.T. support.
I'm not an expert, though.

Add support to this bridge, please.
Or if it is impossible to add, explain this in wiki.

  • Component changed from smartctl to all
  • Resolution set to wontfix
  • Status changed from new to closed

This USB bridge does not implement any of the ATA pass-through SCSI commands supported by smartmontools. It may implement another vendor-specific command. Adding this to smartmontools is not possible without documentation from the vendor.

The ATA compliance of an USB bridge does not imply that full pass-through access to all ATA commands is supported. The SMART feature set is optional and never needed for the normal I/O done by an operating system.

See wiki page USB devices and smartmontools and the smartctl man page section "ATA, SCSI command sets and SAT" for more info.

Please reopen this ticket if smartctl actually works with this device when any of the USB related -d options (sat, usbcypress, usbjmicron, usbsunplus) is specified.

Usage of -d sat,auto triggers no error, but SMART information is not reported either for my old external HDD. Reporting it in case it helps.

# smartctl /dev/sda -d sat,auto -a
