[SOLVED]USB HDD spin down problem

[mackowiakp]

I want to spin down USB connected Seagate USB HDD. It works correctly with M6, RPi and QNAP NAS. But not with M7. Below output from lsusb:

Code: Select all

Bus 003 Device 008: ID 0bc2:3322 Seagate RSS LLC SRD0NF2 [Expansion Desktop Drive]


And from hdparm

Code: Select all

[root@Piotr TMP]# hdparm -S120 /dev/sdc

/dev/sdc:
 setting standby to 120 (10 minutes)
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

Disk does not spi down. What the problem is? As I wrore, it worked with M6 and other Linux`s. Any idea?

You should add the full output of hdparm -I for that disk.

See also https://www.smartmontools.org/wiki/USB or https://www.smartmontools.org/ticket/971 and maybe https://askubuntu.com/a/1106020/329633
The behaviour changed after kernel 4.x at some time for the UAS mode access.

So You have:

Code: Select all

[root@Piotr ~]# hdparm -I /dev/sdc

/dev/sdc:
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

So, what to do?

A know that links.

But you didn't seem to actually read them. The first links to https://www.smartmontools.org/wiki/SAT-with-UAS-Linux which has workarounds. Which one did you try, with what results ?

[mackowiakp]

OMG! I have two identically looking Seagate Expansion 4tb units. Vendor ID is the same but unit ID is different. So I enter wrong unit ID in /etc/modprobe.d/disable_uas.conf file. In my case proper content is:

Code: Select all

[root@Piotr Pobrane]# cat /etc/modprobe.d/disable_uas.conf
options usb-storage quirks=0bc2:3322:u

Thats all. Solved. But why it is so complicated? USB is from assumption something p&p. Not plug and goggle several hours, ask on forums hoping that somebody help. Crazy...

You complain because you bought some weird complicated proprietary hardware ? You may want to think about that again ...

[mackowiakp]

No, I complain because I use the equipment I bought some 3-4 years ago and always worked without problems with everything, including the M6. And now you need to configure something that by definition is plug & play.

It works now but iotop shows 5 M/s for USB v3 interface connection. It is 10 times slower than the same HDD connected to OpenVRT based Asus router, equipped with USB v3 port too. I use in both cases RSYNC over SSH to backup QNAP NAS to HHD`s connected to Asus router and to PC.
Any idea how to seed-up such connection?
