Cache drive disappeared

Recommended Posts

Cached drive disappeared.  Moved it to a new SATA and PSU cable.  Found it again.  Claims to have CRC errors.  I assume that means I should replace it. Can I get confirmation on that? I'm attaching my diagnostics to this post.  

Also, is there a way to protect yourself from drive failure with the xfs file format? other than backup and restore?  Thanks.

Crc errors are nearly always connection issues and related to the SATA/power cabling to the drive and rather than errors with the drive itself.   Note also the CRC error count never get reset so you simply want to stop them continually increasing.


With XFS format cache drive then backup/restore is the only method of protecting yourself against cache drive failure.   There are a plugins that can help with automating this process.
