Hi,
here goes a report. And a call to action.
After 325 hours of desktop use overall 105 times more
bytes have been erased than have been written.
Which is excessive.
I'd be happy if someone would either confirm or disprove
this finding. To help tracking this down I added a script
which hourly records the status of the disk:
smartctl -a /dev/sda | gzip >/tmp/smartctl_`date -u +%Y%m%d_%H%M`.txt.gz
If you care (and have a disk with indilinx controller),
please consider adding this as /etc/cron.hourly/smartctl
And report back.
(hourly data collected here is happily available on request)
I would like to keep discussion here, because
a) the expertise is here,
b) the adequate tool is here (no screenshots from one
or the other Windows application),
c) the perceived problem would likely affect SSDs from
different vendors and
d) I trust mail much more than vendor forums(*)
Please help track this down.
Greetings,
Frieder
