I love the selective self tests feature (-t select,min-max/next/cont[+SIZE]). The long tests just take too long. However I can't get it to work right with smartd.

My configuration is this:

• smartmontools version 6.2

• smartd started with --savestates=/var/lib/smartd/ and verified that state files actually appear in that location

• smartd.conf with -a -s c/../.././17 for all disks

My issues are these:

• when I -t select,min-max a disk (to get things started), this info usually does not make it into the state files. And without the state files nothing works as my WDC disks don't seem to keep the data across reboots

• after adding selective-test-last-start/end manually to the state files, things *seem* to work for a while. But it seems to forget the range size after a couple of days, probably when it reaches the end of the disk?

• one of the disks is a SSD (Crucial M4 64G), and I did a -t select,0-max on it in an attempt to make the cont check always check the entire thing. What happens instead is that smartd actually checks nothing (0-0) every time and the last start/end vanishes from the state file. (I'm aware I should just make an extra config entry for the SSDs that use long tests as they don't take long on SSDs.)

• If possible I'd like to be able to specify the SIZE directly in smartd.conf the same way it's possible to do on the command line (-t select,cont+SIZE). Ideally this should also remove the need of running the first select test manually.

• It would be cool if SIZE could be specified as a percentage, so for example a DEFAULT entry that checks 5% of a disk could be made regardless of disk sizes.

SMART attributes are different on Windows and Linux.

Notable, '175'

Linux:

175 Program_Fail_Count_Chip 0x0033 100 100 010 Pre-fail Always - 4295033464

Windows:

175 Power_Loss_Cap_Test 0x0033 100 100 --- Pre-fail Always - 623 (1 53)

In fact 175 is a bit field containing

Last test result (microseconds) Minutes since last test Total number of tests

which is returned by the Intel SSD toolbox

smartctl -i does not give WWN for SATA disks; still, this value seem to exists, since udev can create it:
