my dell mini 10v running Ubuntu 10.10 runs ok for hours, but then will suddenly slow down drastically. Switching to a console shows lots of error messages, which also get into /var/log/syslog. These errors happen every couple of seconds. I'm figuring that the disk is failing, but is there anyway to be sure, and can laptop disks be replaced easily?

If you go to "System" > "Administration" > "Disk Utility", you should see a list of your hard drives.

Click on the drive in question, and you can check the drive for errors, or view the SMART data and have the drive run some of it's own tests.

It doesn't look like the Mini 10v drives are too buried in the computer - they are directly beneath the keyboard, and are pretty easy to access.

Luckily, someone appears to have posted a great hard drive swap video on YouTube for your model that you can use as a guide.
