I regret that I just yesterday sent a drive back with spontaneously growing read errors that were fixable yet would pop up in another spot. Does this apply cleanly to 2.6.13 though? Does it require any special tool support or superblock (version of mdadm, etc)? I could put it on one of my non-mission-critical rigs and let it run for a while. -Mike - 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
