Intel® SSD 520 Series + smartctl -t long

Description (last modified by Christian Franke)

Why does the smart test in Linux lasts 5-6 hours instead of 48 minutes?

Use command: smartctl -t long /dev/sda

The test is passed by drive. But why is so long? (freebsd 8.4, Ubuntu 14.04). Speed is ok, about 400-450 kbytes/sec. Short test is ok, about 1-1,5 min.

Firmware Version: 400i,

[240 GB] Capacity,

Sata current: 6.0 Gb/s

attach for you log smartctl , why so many in log lines, it's a bug? there is one Self-test routine in progress gonna be i suppose :

# 1  Extended offline	Self-test routine in progress 40% 	16923     	-
....
#19  Extended offline	Self-test routine in progress 40% 	16924     	-

fstrim -v /mnt 

/mnt: 236092682240 bytes were trimmed


smartctl -x /dev/sda

comment:2 in reply to:  description Changed 4 years ago by Christian Franke

Why does the smart test in Linux lasts 5-6 hours instead of 48 minutes?

This is normal if the drive is accessed during the test. Note that "48 minutes" specify a "recommended polling time". It is usually close to the actual self-test time if the drive is not accessed during the test.

attach for you log smartctl , why so many in log lines, it's a bug?

Yes, some Intel SSDs may return garbage in some logs. At least 320 and 710 series are also affected.

Self-tests are done by drive firmware. Smartctl only issues the ATA command to start a test.

Note: See TracTickets for help on using tickets.
