(SOLVED) Another disk read error thread - time to replace drive?


Recommended Posts

While I was away there was a power glitch and fortunately the UPS shutdown the array gracefully. But on rebooting, I got CRC errors and disk read errors on one of my data disks. From reading around, it seems that CRC errors are possibly not too serious. However, disk read errors might be an issue. My diagostics: tower-diagnostics-20180624-2153.zip


Should I replace the drive? If it's recommended that I replace the disk, which is 4TB, can I just swap in an 8TB drive and rebuild?
