ICKDSF EXAMINE will show exactly which cylinders aren't properly formatted, if that's indeed the problem. As suggested previously, the volume should be DRAINed and then the unformatted cylinders detected by EXAMINE can be (very carefully!) formatted using the appropriate CPVOL FORMAT RANGE(x,y) commands without taking down your system. Or, for the faint of heart, flag the offending volume DRAINed in SYSTEM CONFIG, re-IPL, format it, and turn it back on. I also make a point to copy ICKSADSF MODULE to my CF1 disk so it's available for this and other purposes in a stand-alone environment. Mark Wheeler 3M Company
