Modern implementations log both correctable errors (CE) and uncorrectable errors (UE). There is an induced astigmatism that is correctable. Only a tiny fraction of the detected errors end up as not correctable. Treatment is cause-related, but also symptomatic if the underlying cause is unknown or not correctable. This procedure is initiated by the storage control and used to recover from correctable errors. Over 8% of DIMM modules experience at least one correctable error per year. Later another type of correctable film ribbon and lift-off tape appeared, both color-coded orange. These may be correctable on a scanned version of the photograph with image editing techniques. Most of the bugs in the game were correctable by subsequently released patches. I includes the supple clasped thumb, when the thumb is only passively correctable. A new ribbon type, the Correctable Film ribbon, was introduced at the same time.
