I'm confused....I assumed my parity drive was valid before I replaced the bad disc...my last parity check had no errors. After rebuilding the failed drive I had 7 sync errors...and then I ran a parity check with no errors. What should I have done differently?

Re-ran parity check without errors. All seems to be working. Thanks again...

Update: the rebuild is finished. I now get a "parity is valid" message, which make me happy. There were 7 sync errors which has me somewhat concerned because I'm not sure exactly what this means. From the FAQ: Here is the screen shot: I think everything is fine now and I don't need to worry about the sync errors since the parity has been rebuilt and is now valid. Is this correct?

Update: I stopped the array and powered down. Then reseated all drives and restarted. The "red balled disk" stayed red, but the cache drive lost the "unformatted" designation. I have replaced the bad drive and "a data rebuild is in progress. Thanks to all that helped. I will try the suggestion of reading from the bad disk on a windows machine to try and see what's up.

Hi, Have been running Unraid for over 2 years without a single issue. Yesterday the server got turned off suddenly by some contractors doing work in the house. When I turned it back on I got two separate errors. See screen shot below. The first is that drive 10 has "issues." See screen shot below. Essentially it has a red ball beside it and show 576 errors. The last schedulled parity check on the first of the month was perfect. The second issue is that the cache drive now shows as unformatted. The cache drive previously worked great. I'm not sure how to proceed? Should I deal with the bad drive first and simply replace it? Utilizing these instruction from the FAQ: Or should I deal with cache drive first? I have never had a problem before so I'm quite nervous. As you can see I have quite a bit of data and I don't want to lose any of it including that which is on the bad drive.. Any advice appreciated. Also I received an "email" about this error from my machine titled: There is a whole bunch of technical information in the rest of the email which I can attach if needed.
