Ouch. Better keep up to date backups. People have quoted 300000 or 600000 as expected lifetime. This is a Hitatchi drive, and the laptop (Sony Vaio VGN-460) is over 2 years old. I generally keep it on AC power on my desk, and leave it running 24/7 idling on IRC for logs. (Also time to set up an IRC proxy…)
I’ll watch the stats for a day or two before trying some of the workarounds listed in Bug 59695 so I can see if they make a difference. In 30 mins, it’s only gone up by 1, so I don’t know whether it’s a current problem for me or not.
