You can turn the cache back on however. I don't remember the exact incantation to do so, but "format -e" springs to mind.

You can create partitions using fdisk, or slices using format. The BIOS and other operating systems (windows, linux, etc) will be able to recognize partitions, while they won't be able to make sense of slices. If you need to boot from the drive or share it with another OS, then partitions are the way to go. If it's exclusive to solaris, then you can use slices. You can (but shouldn't) use slices and partitions from the same device (eg: c5t0d0s0 and c5t0d0p0). -B -- Brandon High : bh...@freaks.com
