Will a diskpart clean followed by create new primary partition wipe out ASM information in prep for

Greetings-
Long story short, I want to re-use a previously-used set of 10 disk arrays in a Windows 4-node RAC 12/ASM environment.  (So basically the disk arrays need to be wiped out and treated as if they were brand new, empty disks, sort of a data store migration scenario.)

After doing a diskpart clean and create primary partition (RAW), I was able to get through the steps up to:

a) create CRS disk group

b) restore ocr

c) replace voting disks

d) asm password copy

e) get clusters running

But, at the point where i want to create the other disk groups (DATA,FRA,ACFS), I get the error message that there are already such disk groups and that the ACFS is already mounted to a drive letter (the specific error message excerpt is below).  This is all part of a procedure that others have to perform in production so I'd rather that they not have to deal with this and thus would like to know how if the diskpart clean actually is the right thing to do here or if it is irrelevant and there is something else wrong.
