Isolating external HDD after backup from N102
I have an external HDD connected by usb to my ReadyNAS RN102, running firmware 6.9.3
I run a full backup of everything off the N102 to the external drive.
I then want to isolate the external driv...
Hi Protem
Welcome to the Community!
The USB drive being ejected after the backup completes is for safety, It prevents any possibility of file corruption on your data.
Ejecting the drive safely before removal is always recommended, This is to make sure that no activity or action is taking place when you remove your USB Drive.
IMO, Ejecting and unplugging the drive after use is a better practice of protecting what is inside your drive.
Hope this helps!

Hi Protem
If USB is inactive or ejected there shouldn't be any way that it can be accessed by a Malware or any software thru the GUI/Admin page or your system. However, if the attacker is knowledgeable enough to attack the System they might find a way to enable the connection on your USB drive. It will still be better to take it off the Unit.

Those are my thoughts too but it's good to have confirmation.
I will pull out the usb after i've ejected the drive. It is only required to be online for occasional full backup of the entire NAS content.

Another rationale here is the possibility of a power surge (for instance a lightning strike nearby). Those surges can potentially damage the disks (internal and external). Disconnecting the drive of course eliminates that possibility.
Or a power re-connect after a failure could boot the NAS and re-connect the USB
I have checked a power cycle after external drive eject and, yes, the external drive is re-mounted when the NAS is re-powered.
The only safe option is physical disconnection. Of course none of this helps if one is infected with a time-delayed ransomware virus, but in that event all bets are off.
