This is a generic Intel box with a single internal 80GB disk (probably Seagate, but I don't remember. I can find out if it matters)
running 12.04LTS native (ie, NOT a partitioned disk dual-boot with Windows)
Recently, Ubuntu takes a long time to start and the disk makes the 'scrape scrape scrape pause scrape scrape scrape' noise when I start FireFox.
I'm able to see the file system, and have copied important data onto an external USB drive.
Would it help to completely re-install Ubuntu? is it worth it? or should I just go buy another internal disk (which would require a complete new install anyway)
