The plate comes with NTFS formatting and Windows are 6,001,139,904,512 bytes capacity displayed. 797 MByte are programmed with the accompanying programs, but which can be naturally erased (who needs them, they must of course ensure beforehand).
The included WD SmartWare comes for Windows 32bit and x64 for Mac OSX software without backup function is. This is among other things the reformatting the disk for each variable and the establishment of data backups (Windows only!) Possible.
It can also be set so that the contents of the disc is stored in encrypted form. The password (max. 25 characters) you have to manage themselves, - when it's gone, there is no way to recover the contents of (well, by the NSA, we're not talking about ...). I advise on encryption, solely because of the lack of possibility of a low-level restoration in the event of a disk failure!
I use the drive as an external backup of Synology NAS and have it reformatted the DS as a single volume with ext4. It depends on a USB3 connection and the duration of write performance during backup averages 90-100 MB / s.
The hibernation of the plate 1a works both on Windows and on Mac OSX and at Synology!
The warranty period for this disk is not the way 3 but only 2 years! Just as it is also noted on the accompanying warranty and list on the WD support site as well. This is just a hint, as repeatedly drives are offered with a 3-year warranty.
