Hello WD community,
I’ve recently purchased a WD My Cloud EX4 to expand my network storage. I was using a WDMyCloud 4TB unit to store all my digital media and wanted to replace it with something far more expandable. I purchased an empty EX4 unit and installed the only drives I had available (2TB, 1.5TB, 2x1TB). To get the most effective continuous storage space, I configured the drives in spanning mode and copied all my data from the 4TB unit to the EX4.
Now, I want to take the 4TB drive from the old WDMyCloud and replace one of the 1TB drives with it, and I’ve come across some unknowns:
If I remove a 1TB drive from the EX4 and insert the 4TB, will the spanning configuration simply increase the size of the volume?
Will I lose all data in the volume as the EX4 would need to rebuild the spanning configuration after introducing a new drive (and thereby format all the drives)?
Since it is spanning, the 1TB potentially will have some files on it, can I simply plug this drive into any other PC and transfer the files back to the EX4?
I did look through the forums and I wasn’t able to find the answers I needed anywhere else. If someone has already asked these questions please point me in the right direction. I also called WD Support and the gentleman on the phone simply told me to check the internal backup section of the web UI for the answer. Unfortunately, I didn’t find anything there which addressed my concerns.
Thanks to anyone who can shed some light on this situation.
