Well, there is some possibility that it's just a one-time hiccup. More likely, the drive has already exhuasted it's supply of replacement blocks, as modener drives do bad block remapping all by themselves. In the latter case, the drive is about to fail catastrophically. At the very least, I'd keep a very close eye on the drive, and double-check my backups if I saw that happen to one of my drives. Depending on how critical that system is, I may have a backup ready, or replace the drive under controlled conditions before things get worse. http://www.mired.org/consulting.html Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
