After the last firmware update I am also having all that issues to you listed. I bought my EX4 2 years ago and installed 4 red 4 TB WD HDD Raid 5 also on. Until last update I never experienced any issue. I found these suggestions (under my post) and did all of them. Now Ex4 working really fast and smooth even better then before.
Thanks LifeInBinary!
I have not been able to fully resolve all issues but number of occurences of each issue
has been lessened in frequency in which they occur.
After having purchased My Cloud EX4 I have experienced many if not all of what many of you also have experienced. And I have also found some resolutions.
1 - Network disconnects randomly after few min to few hours of use.
Fix: Set static IP address on the router so whenever device turns on it will receive a static IP automatically. (does not always work but helped make the issue occur less often) Also try changing Network speed from “Auto” to 1000 that way it forces Gigabit rather than 10/100 in case it’s trying to use the latter.
2 - Media service db rescan that resets to 0 and also uses up CPU.
Fix: Option 1, goto settings and disable Media server service, Option 2, goto your EX4’s Twonky server page ( http://yourserver:900016) and customize the media db by disabling search for photos and search for videos only as videos tend to be fewer and will generally finish quickly running the scan. Also make sure you uncheck in Twonky server settings rescan on IP change option.
3 - RAID rebuilds constantly and won’t finish or will freeze after
Fix: Try moving files out of the nas and let the scan finish in shorter time before it freezes, because if scan takes too long it ends up freezing the EX4.
4 - EX4 won’t shut down
5 - EX4 locks up and can’t browse the network share or access much of the web admin portal
Fix for 4 & 5, goto settings and under “Energy Saver” disable turn OFF the “Drive Sleep” option.
6 - EX4 does not see the external USB drive
Fix: try plugging the usb drive to your computer and changing permission on the drive to allow “Everyone” RW (read/write) access to it then replug it back into the EX4 and configure the share permissions Having experienced all these problems really were getting on my nerves and I was at the brink of returning this device to the store, except the store doesn’t take 30 day warranty on NAS products.
