Hi

I just bought a usb/sata adapter like this:
  http://www.thinkgeek.com/computing/drives/a7ea/?cpg=ab
lsusb -v is below

Works OK as a hot-plug SATA disk so I can check what's on that old disk in the
corner; but smartctl doesn't work so I can't see if it has any errors, run
selftests etc.

Kernel is 2.6.27-rc5 (I've also tried older kernels)

I plugged a previously zeroed drive in and...

Device: ST332062 0AS              Version:

Local Time is: Thu Oct  9 21:38:16 2008 BST
Device supports SMART and is Enabled
Temperature Warning Disabled or Not Supported

I've tried -dscsi and -dsat but they don't work.

More info below.

So, for the record since I had no luck on google, I had an off-list reply that
pointed here: Smartmontools for FireWire, USB, and SATA disks/systems
  http://smartmontools.sourceforge.net/faq.html#testinghelp

It's an odd URL target - it's actually about the fact that the usb/sata bridges
built into the docks don't fully support the scsi command set in their hardware;
so my SMART doesn't work and has no chance of being fixed by software. Future
chipsets (and some current cypress ones) may have various developments in
hardware to fix this.

HTH someone else.

David

The USB bridge should support SAT (SCSI-ATA translation) and many
don't.  Nothing much can be done about it.  The hardware just don't know
how to do it.

That true that the hardware should support SAT, but even if it support 
it, linux need some patches to support SAT over USB. See 
http://thread.gmane.org/gmane.linux.scsi/43688 and the patch mentioned 
in the thread.

Unfortunately I am a bit busy to try to resubmit it. But I won't care if 
somebody improve it/resubmit it ;)

..

That may be true, or not.  Try "hdparm -I /dev/sde" on it.
If that *works*, then the USB interface *does* support SAT!

Many, many new USB enclosures now have the modern InitIO bridge chips with SAT.

Cheers

Ahh.. Great!  This mostly fixes smartctl operation on at least two
of my USB drive enclosures here:

    1. a recent rev.  2.5" NexStar-3 SATA enclosure.
    2. a 250GB 2.5" WD "Passport" external USB drive/enclosure.

With the patch, this command line works for me:

    smartctl -a -dsat -T permissive /dev/sdb 

And hdparm just works regardless, with or without the patch.

It should work without permissive, permissive was need without the patch.

You said hdparm works without the patch. I wonder how it work. IRRC it 
asks check condition stuff for every command. I am interested to see the 
hdparm --verbose output without the patch.


BTW somebody is trying to push a patch similar to this one to 
usb-storage driver :

..

Mmm... actually, the "-dsat" flag seems to make smartctl mostly work
with and without the patch.  This is on 2.6.25.6 on my notebook here.
Some month I'll update the kernel and fix VMware and wireless again
for a newer kernel, but for now that's what it runs.

Here's hdparm --verbose, sans patch:

hdparm --verbose -I /dev/sdb

/dev/sdb:

...

And here is smartctl -a -dsat, without the -T permissive flag:

Here it is again, with the entire returned sense data shown:

hdparm --verbose -I /dev/sdb

/dev/sdb:
outgoing cdb:  85 08 2e 00 00 00 00 00 00 00 00 00 00 40 ec 00
SG_IO: ATA_16 status=0x2, host_status=0x0, driver_status=0x8
SG_IO: sb[] = {72 00 00 00 00 00 00 0e}
SG_IO: desc[] = {09 0c 00 00 50 01 40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00}
      ATA_16 tf->status=0x00 tf->error=0x00

ATA device, with non-removable media
        Model Number:       Hitachi HTS541612J9SA00
        Serial Number:      SB2D11E4GESWAB
        Firmware Revision:  SBDOC74P
...

I guess it "works" by accident, since the 00 device status
doesn't have the ATA error bit set.  But I suppose this also
means that a failed ATA command would not be noticed either..
At least not without the patch.

Cheers

Yes that seem to case.
I wonder with the patch doesn't make smartctl work without permisive. 
May be your usb id wasn't in the patch.

..

Heh.. I didn't even look at the patch itself.
But if it is relying upon a whitelist to work,
then it's broken by design.

Most new USB drives will be supporting SAT,
and requiring a kernel patch/update (or some other
whitelist in userspace) is a silly way to support them.

Cheers
