Is it possible to use 5.x made disks in 4, > or am I just simply screwed? 5.x use UFS2 filesystems by default. To my knowledge, 4.x does not have any way to access these. You'll have to reinstlal 5.X to get at your data. When installing 5.X, you can use the options in the disk partitioning section to choose UFS1 filesystems, which can be used by 4.X ... and even Linux, I believe. -- Bill Moran Potential Technologies http://www.potentialtech.com
