[Discuss] Advanced Format hard drives

I see the latest Western Digital notebook drives use Advanced Format[1],
which means they use 4,096-byte sectors instead of the usual 512-byte
sectors. Apparently this requires using a fairly recent Linux kernel[2].
(But not exactly cutting-edge. An Ubuntu 9.10 system will have a kernel
new enough to provide minimal support.)

Though even an older kernel will work, if you take care to manually
align your partitions. I gather the worse case scenario is that you
suffer diminished performance from the drive if the boundaries are
misaligned.

Anyone ran into problems using such a drive with Linux? Enough so that
you'd avoid such drives?
