Note1 When using this hard disk drive model with TS-119 Turbo NAS, the hard disk drive temperature will be slightly higher.
Note2 As suggested by certain hard disk drive providers, the hard disk drives of the same brand and series are collectively recognized as compatible with QNAP products if the largest-capacity drive has passed the compatibility test.
Note3 If you are using two 1.5TB or 2TB hard disk drives in TS-209, due to an upper limit of the logical volume capacity, you can only configure the hard disk drives as single disk volumes or RAID 1 disk volume.
Note4 (WD RE4-GP WD2002FYPS) For improved stability, you are suggested to contact Western Digital after Nov 15, 2009 for the new firmware upgrade. Please refer to http://files.qnap.com/download/Forum/WD_New_Firmware_Release.pdf
Note5 (WD Green & Seagate Green) These hard disk drives have passed QNAP lab’s initial verification of compatibility.

Please plug the hard disk drive tray into the drive bay until it clicks into place to avoid hard disk drive detection error.
