Note2 (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 Note3 (WD Caviar Green) These hard disk drives have passed QNAP lab's initial verification of compatibility. However, because many users have reported unstable experience with these hard disk drives, we do not recommend using these had disk drives with QNAP products. Note4 (Advanced Format) Currently these hard disk drives are not compatible with QNAP NVR. Note5 (Hitachi 7K1000.C HDS721010CLA332 1TB) Since the design of the screw position of this hard disk drive model is slightly different from others, the hard disk drives of 2-bay and 4-bay VioStor NVR may not be detected properly. Please plug the hard disk drive tray into the drive bay until it clicks into place to avoid hard disk drive detection error. Note6 (WD Caviar Green) The hard disk drives have passed QNAP lab's initial verification of compatibility. However, the manufacturer has suggested not to use the desktop hard disk drives in RAID subsystems because the drives may not work correctly. Please check this link for more information. Note7 (Samsung HD204UI 2TB) To use this hard disk model with QNAP products, please back up the disk data (if any) and follow the guide below to apply the patch for improved data integrity. http://www.samsung.com/global/business/hdd/faqView.do?b2b_bbs_msg_id=386 Note9 These hard disk drives have passed QNAP lab's initial verification of compatibility. However, because many users have reported unstable experience with these hard disk drives, we temporarily move these hard disk drives to the Not Recommended Hard Drives list. We are still investigating on the root cause and we will update the solution later.
