I check memory/cpu with memtest86, but I would like some way to stress test a hard drive. Currently I dd urandom over it for a few days or DBAN it, but I'm looking for something more thought out. Preferably, a program that can run on a live system so I'd just attach the drive to be tested, and point the test at /dev/sdd or whatever dev it was on. Preserving data on the drive is (obviously) not a concern.

<div>Do take note that Duplidisk is totally OS and application agnostic for it's IDE device role.</div>

<div>Of a 2005 project run involving some 2900 of these there were maybe 3 failures on systems relying on the Dupli, and 1 of those was my being given an incorrect firmware update- which was recoverable from. The other 2? one was in a lab confirming my firmware bug, and the third was "pepsi syndrome-sadly dupli is not pepsi proof.
