You need a fairly recent kernel for drives larger than ~137Gb (2^28
512-byte sectors). 2.6 and the last few 2.4 kernels are OK, but older
2.4 kernels will only see the first 137Gb .
If you think that you might need to access a disk with an older kernel
(e.g. a rescue disk or a bootable CD from a not-so-recent
distribution), you might want to partition the disk so that everything
important is on a partition which doesn't extend beyond the 2^28
sector barrier.
There is a guide to the various disk size barriers at:
http://www.pcguide.com/ref/hdd/bios/size.htm
Most of these are either BIOS issues or DOS/Windows filesystem issues,
so they aren't an issue for Linux (other than for booting, as the boot
loader relies upon the BIOS for disk access). However, the 137Gb limit
is an ATA issue rather than a BIOS issue.
