Is it possible that it has something to do with timeouts? I have a couple of velociraptors in raid 1, and other then a couple of drive timeouts I haven't had any serious issues. Perhaps he can try running WDTLER utility on the drive? (I believe its on the wd tools ISO) Russ ------Original Message------ From: Redeeman Sender: linux-raid-owner@xxxxxxxxxxxxxxx To: Nifty Fedora Mitch Cc: MOgWai46[Saurceful of Secrets] Cc: linux-raid@xxxxxxxxxxxxxxx Subject: Re: Western Digital RE3 Sent: May 27, 2009 9:17 AM On Tue, 2009-05-26 at 18:24 -0700, Nifty Fedora Mitch wrote: > On Mon, May 25, 2009 at 04:17:34PM +0200, MOgWai46[Saurceful of Secrets] wrote: > > > > Hi! > > > > I would replace two Western Digital Velociraptor 300 GB 10K Rpm that > > in the latest five month gave me a lot problems.

He is not the first person to have serious problems with the velociraptors, so they are probably not too good to use for raid. > > > -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html Sent from my Verizon Wireless BlackBerryÿôèº{.nÇ+?·?®??+%?Ëÿ±éݶ¥?wÿº{.nÇ+?·¥?{±þ¶¢wø§¶?¡Ü¨}©?²Æ zÚ&j:+v?¨þø¯ù®w¥þ?à2?Þ?¨èÚ&¢)ß¡«a¶Úÿÿûàz¿äz¹Þ?ú+?ù???Ý¢jÿ?wèþf
