There are drivers, at least in 2.6. Raid should > care about what sort of disks you use. When using it for normal disks e2fsck reports bad blocks all over the disk. When used for RAID, I get corrupted data. Not much, maybe every second time for a file of 500MB. This is with the IDE driver. With the SCSI driver, my computer completely freezes when I activate my second network card (as I reported earlier, unfortunately still without a solution). RAID might work with that driver, but unless the network card problem is solved, that doesn't help me. > > It doesn't work with VIA (yet, anyway). > > It might work with HighPoint. > > I've run RAID5 on a Highpoint RocketRAID 1540.

Why the warning about Promise? The reason I want the VIA driver to work is that I've got two VIA connectors on the motherboard, so I only need a 2 port SATA card. /Basic - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
