November 30, 20205 yr Hi there, I have purchased a new drive for my cache drive as well as a new data drive. The data drive will be used to replace my smallest data drive. In the past, I've replaced a data drive, but never my cache drive and certainly not two drives "at once"- To that end, should i replace the cache drive then the data drive or the other way around? Similarly, is there away to replace both concurrently or do i have to do one at a time? Lastly, I intend to follow this guide: https://wiki.unraid.net/Replace_A_Cache_Drive and watch this video: https://www.youtube.com/watch?v=ij8AOEF1pTU Are these guides still the best to follow?
November 30, 20205 yr Since you will be moving things from cache to array so you can replace cache, then you definitely don't want to do that while also rebuilding one of the data disks. Do any of your disks have SMART warnings on the Dashboard page?

Do the replace / rebuild of the data drive and when that completes you can do cache. Be very careful about all connections including those on disks you aren't changing. That is the most frequent cause of rebuild problems.

December 1, 20205 yr I think @trurl just means that when replacing a drive it is very easy to mess up the connection of other drives for DATA or POWER.
