I considered buying an adaptec sata raid (hardware). One of the drawbacks on hardware raid is the format isn't compatible with any other card (or rather manufacturer). So the question is, has anyone written anything that can detect and activate disks from a hardware raid controller when they are placed on a controller w/o any raid? basically what I mean is, 3 disks, raid5 was in a system with hardware raid. the raid card blows up and cannot get another one so to get the data back, place disks in another machine or on a standard controller and use software raid or whatever to recover the data. -- Lab tests show that use of micro$oft causes cancer in lab animals Got Gas??? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
