if i want to put in a new harddisk in my Readynas duo, which allready got movies on. Will they be deleted when i start the nas or will it just install the os and dont delete anything?
It will wipe the disk, so all data will be deleted. You must backup your data first if you want to keep it. If you value your data you should backup your data regularly anyway.
So first install a different hard drive of the same size, create shares on its C volume, and copy your files onto it over the network. Then install the drive with the movies as the second drive. It will be wiped, and you will end up with a RAID-1 C volume (protected against 1 drive failure). This will be the same size as your existing drive (not 2x).
RAID is helpful, but doesn't guarantee data safety. So you will need a backup of some kind - a USB drive perhaps.
If you using the default xraid2, you want the drives to be the same size.
If you start with a 1 TB drive, you can add a 2 TB. But you are wasting space (you end up with a 1 TB shared volume with redundancy)
If you start with a 2 TB drive, the system will not let you add a 1 TB.
You can use jbod (flexraid), which will let you create two volumes (one on each disk). Then you'd have 3 TBs total, but wouldn't have any RAID protection at all. Generally new users are better off with the default xraid-2.
i now installed a new formated 2 tb WD green harddrive. in RAIDar, first i see, booting and then i says update - and then i just stand like this (see pic below) for several hours. at my fathers place, he´s gonna have it, it stod like that for 24 hours, and then i turned it off, because the fan was to loud. now i will try at home, and it´s no better. i´ve tried to reset it with the reset buttom at the back. turn off power, hold down reset, turn on power, wait for light in disc 1-2. still nothing ? im a doing something wrong ?
You can try removing the drive, connecting it to a Windows PC, and deleting all volumes on the drive with Windows Disk Manager (right-click computer, select "Manage"), and inserting it again. Deleting the volumes will return the disk to an unformatted state.
