I have both an 811S (HS0Q) and 851S (GS2C), both firmwares Omnipatched. The drives, however, give drastically different scans - for example, on one disc the 851S would have a max PI error of 20 and the 811S max PI error on the same disc would be ~1300-1400. I had some time to kill and tried a couple of things:
- Reflashed to unmodded HS0Q firmware - no change
- Reflashed to HS0K, HS0P firmwares - no change
- Reflashed the original EEPROM backup I’d made of the 811S when the drive was brand new - big change. The max PI dropped from ~1300 to ~600-700. Obviously not back to “normal,” but it indicates something happened to the EEPROM over time to make the scans worse.
Anyone’s thoughts on this?
