I'm assuming IDE drives, since this doesn't sound like a SCSI scenario. IDE, is well, 'not Scottish'[1] Even if your software RAID is no longer using the device it doesn't mean that the device won't try to communicate with your system and vice versa (at a hardware level). If you've got another device on the same cable as the failed drive, if the failed drive may try to respond. Either way you get issues. So no, likely there is nothing wrong your raid configuration. I'd suggest scsi drives and, better yet, hardware scsi raid if you can afford them, but with standard ide components there's not much to be done. hdparm _might_ allow you to detach the failed device from the ide bus, but I'm not really sure. [1] There a saying, "If it's not Scottish, it's crrrrap!". Of course as I am not, I don't believe it. -- And that's my crabbing done for the day.
