CATDVSVR2WN1-000003-sesparse.vmdk has no descriptorfile.
To create that descriptirfile from scratch you need to know the content of the descriptorfile of the vmdk that comes before the missing one and the one that comes after it.
In your case this very likely are this ones:
CATDVSVR2WN1-000004.vmdk and CATDVSVR2WN1-000002.vmdk
So if you attach both to your next reply I will create the missing one for you
