April 30, 201412 yr I lost power in the house (again) and I have yet to install a PSU (ordering one now). Parity calculation kicked in automatically and it completed (Parity is valid) but reports Parity updated 258 times to address sync errors. Have I lost any data? How can I find out if I did?

Basically you cannot! The assumption is that the error is vastly more likely to be on the parity drive so that is corrected if you successfully read the relevant sector from all the data drives. You cannot tell what files the corrected sectors relate to. The only way to know about data is to have CRC checksums for all your files created when you added the files to the array, that you can now use to determine if any have changed contents.
