With BCHC and BCIC, WOPC doesn’t work the way it should with CMCMAG E01.
No WOPC occurs before 2.7GB.
IF SB is activated, though, WOPC works the way it should.
Information verified (4 users). Didn’t check BCFC.
While with premium CMCMAG E01 (HP-branded for example) it can be OK (though still risky) to burn without proper WOPC, with cheaper discs it’s a total crapshoot.
If you had poor CMCMAG E01 burns with BCHC or BCIC, now you now where to look at.
A last thing: this behaviour doesn’t change unless you uninstall Qsuite before downflashing (to BCDC for example). Then resintall Qsuite.
Hope this helps.
