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. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
