PI (Parity Inner): No larger areas on the disc should exceed 280 PI errors, do not worry too much about high single spikes that exceeds 280.
PO (Parity Outer): No larger areas on the disc should exceed 32 PO (actually PI uncorrectable) errors, do not worry too much about high single spikes that exceeds 32. (Note that this is not completely correct according to the standards, but is still a good guideline, read the first technical post if you wonder why this is not a 100% correct way of reading the results compared to the standards).
直接找出來,數字因該看的懂吧!
