Hi guys can anyone recommend a tool for thrashing the b*ll*cks of a
drive in way that isn't destructive to the data?
I was thinking badblocks with -w but it is destructive and i dont
want to do anything that will potentially lower the integrity of my
array? (Even tho it is raid6 :) )
There must be some bonnie esk tool that will read/write every
combination to every block but keep the data safe after to flush out
any sector issues etc.
Here are a couple of utilities I've used in the past:
- seeker: How fast is your disk?
<http://www.linuxinsight.com/how_fast_is_your_disk.html>
"With a little bit of torturing, and some fun on the way, find out
how fast your hard disk drive really is."
- thrash - hard disk stress tester with random seek speed statistics
<http://www.csc.liv.ac.uk/~greg/thrash/>
"thrash is intended to exercise a hard disk seek mechanism and
perform a random seek speed benchmark. It is largely targeted at new
harddisks that should be exercised to encourage early failure (i.e.
assuming a bathtub curve for failures)."
Also, as mentioned in the first article, you can use hdparm to test
sequential access.
I believe all of these utilities can be used read-only, but I can't
remember for sure.
