Drives don't reallocate sectors until you write over them, to give you a chance to try rereading them in the hope you'll eventually get a good read. And unless the counts are high or growing regularly you don't need to panic. While there is a correlation between bad sectors and drive failure, it isn't as high as you might think. If the data is valuable and money isn't a big concern, sure replace the drive promptly. If you're on a tight budget and you have a way to easily recover if the drive fails suddenly, then you might play russian roulette. Drives with a couple of bad sectors can run years before failing. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
