Since DSM 5 uses OpenSSL it is affected by the SSL Heartbleed Bug: http://techcrunch.com/2014/04/07/massiv ... -internet/
So until it's fixed your https connection to your XPEnology DS is not secure and all data could be decrypted (including your credentials).
So he has to update do 3827 first since it is a "big" update: http://xpenology.trantor.be/beta/
Afterwards you can update to DSM4.3-3827 update 1 as described above!
How I fixed HDD not sleeping problem on N54L:
-Change the time (minutes) after which the HDDs should go to sleep an save-
-Change back to the desired time and save
Sleeping should now work!
If your data is worth the cost of an real Synology DS and you have no idea what you're doing, you should get a real DS. It's up to you to to know and ret the risk, since it's your data that will get lost. So if you're not 100% aware of what are the risks, get a real DS.
Vermutlich meinst du N54L und das gehen sie bei mir problemlos ins den Standby. Bei meinem USB-Stick habe ich allerdings auch die PID und VID geändert, so dass dieser nicht angezeigt wird.
