its not? what about looping it? i usually get bonnie++ to run in
a loop for about a week, writing 1-2GB worth of data for each
pass..
bonnie++ is a pretty good test since it writes a lot of files and
reads a lot of files of various sizes.
in my experience(and i've had about 16-17 drives fail on me in
the last year), burning in doesn't mean much. Most of my drives died
several months after they were put into production, after they passed
the vendor's burn-in, my burn-in, and 2-3 months of real world usage.
(~95% of my failed drives were IBM 75GXP avoid them at all costs).
its very difficult to try to find a defect in disks since they
usually automatically repair many of the errors(I have a maxtor 80GB
that i would say "hiccuped" about 6 months ago, and I lost some
important data, about a month ago I finally decided to repair
the errors, which only showed up on a lowlevel scan using maxdiag)
it ran for 5 months without another hiccup. then I ran it through
lowlevel format, and factory re-cert(3 times). drive is working
good still. IBMs on the other hand when they start to die there
is very little time(hours, days at best) between when it starts
and when the chance of data salvage is virtually nil.
best advice is just build the systems well and you shouldn't
need to worry about problems. most of my disk failures were
caused by bad disks(75GXP is well known to be a bad model of
drive), and weak power supplies in some systems. Once I upgraded
to Maxtor drives and (PC Power & Cooling) 450watt power supplies my
failures went from ~3/month to 1 in 10 months(out of about 50 IDE
drives I have in service).
good luck hopefully you don't have any IBM ide drives.
