I made a typo--the Plexwriter Premium measures C1, C2, and CU errors.

C1 is a combination of E11 E12 and E13 which Plex claims is BLER
C2 is E22
CU is E32

My apologies.

I know this doesn't tell the whole story. The drive also gives Focus Errors
and Tracking Errors.

Finally, it measures Beta (the balance between pits and lands) and also Jitter.

Sorry for the typos, and thanks to Dr. Hartke for pointing it out.

Cheers,

Richard
