Does the LSI MegaCLI utility work for you?
MegaCli -CfgForeign -Clear [x] -aN|-a0,1,2|-aALL
x - index of foreign configurations. Optional. All by default.
and if you want to completely clear the entire drive:
MegaCli -PDClear -Start|-Stop|-ShowProg |-ProgDsply
-PhysDrv [E0:S0,E1:S1,...] -aN|-a0,1,2|-aALL
MegaCli -pdclear -start -physdrv '[32:1]' -a0
(often the internal drive enclosure is "32", and i presume your drive
in enclosure slot "1")
