I'm getting drive read errors every now and again.
The two 60GB drives are a few years old now and have seen their share of miles in the car.

I've been thinking when the situation goes completely 'tits up' (to quote Brit vernacular) I'd go with a 128GB SATA SSD, which are occasionally around the $200 level these days. example

The drive and an IDE-SATA adapter is the plan, but I don't know if anyone has tried it or not.
