I bought some old drives to use.  While rebuilding parity (Due to more than 1 old drive broke down), I decided to rebuild parity.  While doing this, I encountered errors.  Can I still use the drive that have errors came out?

Parity isn't 100% valid because of the errors, you should remove those disks and re-sync parity.

Disk5 basically has nothing on it yet.  If I remove Disk9 (full), will the parity be able to rebuild to the replaced disk?  Which do you suggest I do first?  I assume 1 after the other.   How should I go about it?

Parity can't reliably rebuild any disk since there were errors during the sync, disk5 appears to be failing, there's no SMART report for disk9 in the disgs posted, please post one.

Thank you JorgeB.  I pulled out Disk9 first, and replaced with another one.  Will see.  Luckily, the data there isn't so important.

Is there any way to test integrity of drives in the array?  

Run an extended SMART test on all, parity check is also a good test once parity is valid.

Thank you @JorgeB!
