Without any flags, you're not usiing interleave (striping) or mirroring, so you should be OK. >>> When I try to do what the below cut shows, the system hangs!

I think this answer is less than scientific. I haven't tried all possibilities, but it shouldn't do this. If you have this problem, you should try to figure out why it is happening. >>> **************************************************************************** >>> >>> [root@ralph /root]# newfs /dev/rccd0c >>> Warning: 3462 sector(s) in last cylinder unallocated >>> /dev/rccd0c: 87290490 sectors in 21312 cylinders of 1 tracks, 4096 >>> sectors >>> 42622.3MB in 1332 cyl groups (16 c/g, 32.00MB/g, 7680 i/g) >>> super-block backups (for fsck -b #) at: >>> 32, 65568, 131104, 196640, 262176, 327712, 393248, 458784, 524320,589856, >>> 655392, 720928, 786464, 852000, 917536, 983072, 1048608, 1114144,1179680, >>> 1245216, 1310752, 1376288, 1441824, 1507360, 1572896, 1638432, 1703968, >>> 1769504, 1835040, 1900576, 1966112, 2031648, 2097184, 2162720, 2228256, >>> 2293792, 2359328, 2424864, 2490400, 2555936, 2621472, 2687008, 2752544, >>> 2818080, 2883616,[hangs here!!!] This would appear to be in the first disk (offset 1.4 MB from the beginning).

You might like to try this with Vinum (http://www.lemis.com/vinum.html) and see if that works. If not, I will certainly help you find out why not. Don't be put off by the fact that Vinum is still Beta; ccd really is too.
