I had a long discussion/argument with Western Digital about a decade ago. Drives with TLER (a WD invention) are useless with hardware RAID controllers because they will give up too soon and return an error. In my case I was successful in getting them to replace a pair of TLER drives with equivalent non-TLER versions since at that time their marketing fliers did not point out this limitation. They do make "Enterprise" class drives that do not have TLER. Here's what I have in my current RAID setup (LSI 9650SE-4LPML) 2 x WDC WD1500HLFS-01G6U1 (150G 10k RPM enterprise-class) 2 x Hitachi HDS723020BLA642 (2T 7200 RPM drives) Before buying the Hitachis I emailed their tech support to confirm that they did not do any error-recovery limitation. -- Jim Garrison ([email protected]) PGP Keys at http://www.jhmg.net RSA 0x04B73B7F DH 0x70738D88 _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
