I have tried to upgrade 3 times to the latest firmware but every time my usb drives are not liked by the latest Firmware.!!
My setup is WDMycloud to 4 way usb3 hub with 2 self powered usb3 drives connected and 1 usb2 drive usb powered.
it is apparent that a lot of usb3 enclosures do not spin the drives down when not being accessed (Google it). therefore I need to switch the drives off when I am not using them (the usb powered usb2 drive is never disconnected but spins down when not accessed,
with firmware version 030401 everthing works well and even after downgrading the firmware the drives are recognised quickly and accessible and can be turned off and on whenever required (ejecting the drives from the dashboard makes no difference except for the “unsafe device removal warning”) the usb2 drive is always accessible, and this has worked for months so is good.
Now when I upgrade to version 4.00.01_623 the upgrade goes ok and recognises the usb2 drive quickly which is permanently connected and when I switch on my 2 usb3 drives it takes quite a while before they are mounted and accessibble with an “internal usb server error” message generated for each one but it works. and the WDMycloud will eventually sleep.
if I then turn off the usb3 drives the WDMycloud wakes up temporarily but will eventually go back to sleep.
the problem starts when I turn the usb3 drives back on,
the WDMycloud then becomes totally unresponsive and the dashboard cannot be accessed and on the odd occasion that access is available no usb devices (including the usb2 drive that has always been accessible) are detected but the usb shares are listed (although they cannot be accessed from the network) and the capacity for the WDMycloud is blank,even WD Quick View shows 0% and no usb drives.
as stated this arrangement has been working for months without issues on the old firmware and the only reason I want to upgrade is to use safepoint backups to usb which doesn’t work on the old firmware.
The hub can be powered or not and the drives ejected or not but this all works with the old firmware and not the latest so why break what ain’t broken
