- What would you guess that the odds are that this is actually happening to
- anybody? I'm running on the most basic Linux-capable system--16 Mhz 386sx,
- with just 2M of RAM--so I expect that I'm getting hit by it if it's happening
- to anyone. I plan on repartitioning my hard drive soon anyway, I could
- reformat with a 2:1 or even 3:1 interleave at the same time...but I thought
- that the days of 3:1 interleaves were gone forever when I moved into double-
- digit Mhz ratings.
