My 5TB doesn't ever flash or dim; a little annoying. > I only *feel* safe, pulling the cable when the light is OFF. If you're really worried, first remount the partitions readonly, which will fail if they're in use.

I can already see whose post yours is commenting on. The rule is simple: Change the subject line if the subject changes, Don't change the subject line if the subject doesn't change.
