I have MyBookLive WDC WD30EFRX-68AX9N0. When I filled the storage to 2.9 TB (total is 3 TB), it started “breaking” when I copy a lot of small files to it. By “breaking”, I mean it becomes very slow. Reading from it is still possible, though slow, while writing becomes unusably slow. If I power-cycle the device, it gets fixed. Then if I e.g. run robocopy to copy lots of small files, it breaks again.
I tried the following:
- freed ~200 GB
- then reset device to factory defaults using quick format
- then reset device to factory defaults using full format
Nothing helped. After factory reset, the device works fine. I run robocopy to copy ~800,000 files to it (total size way below 3 TB), and after ~200,000 files the device “breaks” as described above. In “broken” state, the drive’s LED never goes blue (sleep mode), it always stays blinking green, which according to the manual means “performing read or write operation”. Rebooting the device fixes it, but then after copying a few hundred files it breaks again.
Any help will be appreciated.
