Re: [smartmontools-support] Problem with scheduled selective self-tests

[<Tob...@gm...>]

Hi Christian,

thanks for your answer. It's like you wrote, the problem was my HD:

Model Family:     Western Digital Scorpio Blue Serial ATA family
Device Model:     WDC WD5000BEVT-00A0RT0
Serial Number:    xxxxxxxxxxxxxxxxx
Firmware Version: 01.01A01
User Capacity:    500.107.862.016 bytes
Device is:        In smartctl database [for details use: -P show]
ATA Version is:   8
ATA Standard is:  Exact ATA specification draft version not indicated
Local Time is:    Tue Aug 17 18:51:28 2010 CEST
SMART support is: Available - device has SMART capability.
SMART support is: Enabled


I tested it with another HD and everything was okay:
Device Model:     SAMSUNG HD203WI
Serial Number:    xxxxxxxxxxxxx
Firmware Version: 1AN10002
User Capacity:    2.000.398.934.016 bytes
Device is:        Not in smartctl database [for details use: -P showall]
ATA Version is:   8
ATA Standard is:  ATA-8-ACS revision 6
Local Time is:    Tue Aug 17 18:53:24 2010 CEST
SMART support is: Available - device has SMART capability.
SMART support is: Enabled


To restore the last span would be a nice feature

Best regards and thanks
Tim

Looks like this (which?) disk model does not preserve selective self 
test log across power cycles.

To test, please run a very short selective test and check selective self 
test log before and after power cycle:

# smartctl -t select,100-110 /dev/sda

(... wait until test completes ...)

# smartctl -l selective /dev/sda
...
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 ? ? Not_testing

# shutdown -h now

(... boot ...)

# smartctl -l selective /dev/sda
...
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 ? ? Not_testing


For the future, it may be possible to restore the last span if 
--savestates is used.

Thanks,
Christian
