Hi - I have a system with two IDE drives on it and I need more disk space
than I have . The current situation is :

Filesystem  1K-blocks    Used  Avail Capacity  Mounted on
/dev/ad0s1a    257998   36308 201052    15%    /
/dev/ad0s1f    498398  424568  33960    93%    /usr
/dev/ad3s1e   7939980 6610848 693934    91%    /usr/home
/dev/ad0s1e    226734    2542 206054     1%    /var
procfs              4       4      0   100%    /proc

I would like to swop the 1Gb ad0 drive for a larger drive. As you can see
the other IDE drive is almost full. Can anyone suggest how to move what's
on ad0 to a larger disk ? I wondered about 

1. disconnecting the ad3 and putting a new drive in its place
2. then (in some way) backuping up the entirety of ad0, restoring it to
the 'fake' ad3 3. then taking out the original ad0 and replacing with ad3
4. then (in some way) persuading machine to boot off new, larget drive,
with root on it 

... would that work  ? Can anyone fill in the details ? It it wouldn't
work can anyone suggset an alternative bearing in in mind I can only have
two drives and the largest each can be is 8Gb (old BIOS). 

regards

richard shea.
