sleep at last

For the first time ever, I was able to successfully suspend my laptop (IBM T40p) to RAM. For the longest time I was having a problem where the disk would go completely insane upon resuming. Very annoying.

I found out recently that it was probably due to the BIOS re-enabling HPA (Host Protected Area) when coming out of sleep. Unfortunately, there didn’t appear to be any kind of workaround for it, but tonight I discovered that you can use the Hitachi Feature Tool to disable it for good. It totally fixed my problem. Woo.
