I was quite happy user of My Cloud gen2 4TB for several years, but now i need more storage space, so decided to upgrade hdd to 8TB.
I purchased WD My Book 8TB for good price, took out the hdd, and carefully tested it and use for My Cloud upgrade.
First i followed this replace guide here:
All worked fine until time to upload a new firmware, i always ended here with endles waitiung loop after i selected a firmware file. I tried more different fw versions according various advices here, but nothning helped.
Finaly i tried another guide, with few little differences and it was successful:
My Cloud is now fully working, with good speed (on 1GBit cable 110MB/s, 50-60MB/s on G5Hz wifi, on Netgear R7400).
But sometime it behaves weird, webGUI is significantly slower that before, and sometimes transfer speed decreases to very very low, max 10MB/s on big files, and only low kilobytes/s when transfering smaller files.
Nothing helps, only restart of MyCloud device. After cloud restart the same file transfer is resumed in good speed (above 100MB/s).
After some time (hours? days? I’m not sure when and why…) it again falls into “low speed mode” and only mycloud restart will solve it.
I’m sure it is not hardware problem, i never experienced this with my cloud device before hdd replace, and new 8TB is also carefully tested and 100% ok.
Any ideas how to solve this?
