I'll try to suggest some other alternatives, as you wish. If this is "the key machine" for your network, however, you should consider what the consequences of this disk drive failing completely are. [ Modern hard drives have failure modes that include "you don't get the data back". So if you don't have a good backup of the system already available, take one right now. ] > All in all I would say 10 hours work, a few weeks of waiting. Yes. Or you could get a replacement drive for less than $100 now, and copy a working system so that you don't encounter unplanned downtime for this key machine, wait for an RMA, or anything else. > So why not first try something (if it exists, which was my question) > that does not involve picking up a screwdriver and turning of my > network here?

Dude, IDE hard drives have moved from having a 3 year warrantee to a 1 year warrantee for a very simple reason: the percentage of IDE hard drives which fail after one year is high enough as it is. Anyway, one can use dd as a non-destructive read test-- although the manufacturors' utilities can test more effectively (as well as look into the SMART status and so forth, if applicable). I believe the system installer lets you invoke the bad144 destructive scanner (via wizard mode), if you wanted to do that. -Chuck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
