I've been trying to do some SDI cleans, and I keep running into this error:
SUM-GI> SDCLN2: TABIO: BAD CODES - TYPE, OP = 0 WRIT
I'd like to play around with some parameters, but nearly every time I've tried
SDI cleans it runs into this error somewhere along the way, so I never
get an image to check. Are there any parameters I should be
particularly careful about?
Thanks,
Adam
