Greetings,
I’ve got an 80 GB LaCie USB hard drive that I use for backups. It works well but it doesn’t always want to register with my system.
For example, in /var/log/messages I see the following when there are no problems with the drive

The only way to fix the problem is to unplug the drive and plug it back in. I was hoping to find out why it wasn’t registering and what I could do to fix without having to unplug it.
Any advice would be greatly appreciated.
