Thanks for the info. Actually, I wasn't aware of ATA having twice the seek times as SCSI and an order of magnitude worse error rates. Why is that? Seek time is just a matter of the mechanics of the head mechanism, right? Do the heads differ between ATA and SCSI? And where do the higher error rates come from? From read errors on the media (I have heard as yet unsubstantiated rumors that SCSI devices get the media that tests higher for quality but that it all comes from the same production process) or errors introduced in the ATA bus? -- Tracy R Reed http://ultraviolet.org -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
