Description (last modified by Christian Franke)

This is a "portable external" SSD (meaning, connected via USB.

With no -d XXX or with -d auto, smartctl -a shows:

/dev/da17: Unknown USB bridge [0x090c:0x1000 (0x1100)]

Experimenting with the various -d options, only -d scsi results in something:

Summary: HP P500 portable SSD not being correctly handledHP P500 portable SSD not being correctly handled (0x090c:0x1000)
Type: defectenhancement

If none of the -d TYPE options mentioned on the USB wiki page work, this can only be fixed if documentation about possible vendor-specific pass-through functionality is available.

Does this device use NVMe instead of SATA internally ?

0x090c is the USB Vendor ID from Silicon Motion (http://www.linux-usb.org/usb.ids).

None of them worked. The only one that didn't return a short one-line error message was -d scsi`.

this can only be fixed if documentation about possible vendor-specific pass-through functionality is available.

I located HP's datasheet on the SSD drive, but it doesn't seem to include any such information:
https://ssdhp.com/wp-content/uploads/2019/11/HP-P500-Datasheet-V4.pdf
(I've attached a copy to this ticket, for archiving/convenience purposes)

Does this device use NVMe instead of SATA internally ?

Good question! Is there a way to find out using smartctl?

0x090c is the USB Vendor ID from Silicon Motion

Thanks for the pointer. I should have thought about searching for the USB IDs... Just did it and found some interesting information:

  • #1422: another ticket here, refering to the same issue but with another 'portable SSD' drive, with the same USB VID/PID.
  • Anyway, I blind-emailed (ie, "support@…") a request for documentation; at least it hasn't bounced yet (meaning, it probably arrived at some mailbox there).

Is there anything else I can do to help?

This is a direct USB(SCSI) -> Flash controller not using a detour via a SATA or NVMe. So it might not provide any (S)ATA- or NVMe-like diagnostic info. It should provide SCSI/SAS diagnostic but the -d scsi output shows that this is not the case.

Thanks for contacting Silicon Motion. Unfortunately this kind of information usually requires to sign a NDA. This is obviously impossible if the resulting source code will be public.

Leaving ticket open as undecided.

Thanks for your prompt response, and of course for the great piece of software that is smartmontools.

I will let you know if I hear back from Silicon Motion. If I manage to get the docs and have to sign an NDA, perhaps we can work it out by your not signing it, and I reading it and understanding it and explaining to you only what you need, with the exchange fully documented and in the open here (like Phoenix did with re: the IBM PC BIOS so long ago). This way the NDA is obeyed and we manage to get smartmontools to support one more device.
