Everything seems to be working very well! I appreciate everyone's recommendation on this issue. I have a follow-up question -- the RAID is made up of 2 refurbished drives we were able to obtain (cost issues). I'd like to find a command / program that I can use to test them / stress them while they are still in their warranty period (90 days). I've done some research and came across a lot of options: Bonnie++, badblocks, fsck, smartctl -t, etc etc. I'm not sure what is best to use -- I guess I want something that will check to see if there are any existing current issues and something to put the drives under some tests to see if any issues arise. The other side of that question is: will the drives being in RAID affect these tests at all? Should I run the tests on the RAID array or should I dismantle the array, run the tests, then re-enable the array? Thank you!

Install the hard disk into your system. 2.) Make two partitions of about equal size on the hard disk. Use fdisk or whatever you prefer. 3.) Format both partitions *simultaneously*. That means start one format command, and then start the second one very shortly thereafter. In UNIX parlance, that'd be "make filesystems on each partition simultaneously." What will happen when you start that second "mke2fs" command is that you will hear the read/write head going back 'n' forth like crazy. I would just do that over and over again for about a week, on each disk, on both partitions. This is, of course, scriptable, so you can set these "mke2fs" commands in a do-forever loop and just let it do its thing. No, there's nothing saying you can't install both hard disks and have both of them subjected to this treatment at the same time. Probably save you some time to do so. Yes, I am cruel. And I'm proud of it. :-) --TP <div class="moz-signature"> _______________________________ Do you <a href="http://www.gnu.org">GNU</a>? <a href="http://www.cmosnetworks.com">Microsoft Free since 2003</a>--the ultimate antivirus protection! </div> </body> </html>
