Replacement power supply, who sells them?
Hi I purchased a ReadyNAS NV+ in 2009 which has been my main backup system until very recently. It started giving signs of power supply frailty so I have just installed a bigger better faster NAS and was about to do a staged transfer of all the non-regular backup data across to it. Of course the inevitable happened and the PSU blew up with a very audible bang tonight before I had managed to copy very much at all. I actually can't find my model on the Netgear site: the plate on the rear says very clearly "ReadyNAS RND4000 v3"; I bought the chassis and supplied my own disks. I'd like to get the data off these disks if possible, there are some precious things in there like family albums and a video of my son's funeral that I'd be very upset to lose. I used the proprietary data striping that means I can't just mount the disk drives iin another system. Got to be this one (and hoping that the PSU didn't destroy anything else when it blew). Regardless of the model number this unit is out of warranty by some years. Does anybody sell a suitable replacement power supply? The Netgear support site doesn't make it very easy to find out if it's possible for me to obtain one from them. Cheers TSolved
Avoid Seagate ST8000VN0002 - Horrible noise issue!
Hi, I have installed four of the Seagate ST8000VN0002 in my RN716x and just finished the resync of all disks. Unfortunately I now have an annoying beeping/humming noise when the disks are idling. It's a pretty bothersome frequency and really nerve wrecking. As soon as there is some read or write access this humming disappears and the normal known sound of harddisks can be heard which is ok. But the humming sound is so annoying that I can absolutely not recommend these disks at all. You should stay away from them. Hope it helps Campus
Spinpoint F4 HD204UI 2TB 5400 RPM working good so far
There was a recent deal at NewEgg on the SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM 32MB drives, so I decided to risk it as opposed to the other WD & Seagate 2tb drives. I installed them, upgraded the ReadyNAS firmware then did a factory reset. Disk 4 took most of an evening to resync, but finally finished. So far it's been running fine as I've been copying data off my old NV+ on to the new Ultra 4. The Ultra 4 is sitting in the bottom of my gun safe, so low heat is rather important to me and I thought a 5400 would be a better bet. So far I haven't seen any Temp1 above 140f or so and the HD's are usually at or under 100f, never seen one above 108f. I was worrried that the enclosed fireproof safe would end up retaining too much heat, but it's been 3 days now with no problems. When I have the safe open the drives are very quiet, not surprisingly closed you can't hear a thing at all. Will try and post later when I see how they hold up.
WD RED PRO 6TB WD6001FFWX vs WD6002FFWX
Hi all, anyone any experience with the WD6002FFWX (as oppososed to WD6001FFWX which is on the compatibility list)? We can no longer order the WD6001FFWX and I want to know if the WD6002FFWX is a supported alternative. According to this sheet http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-800022.pdf the transfer rate has slightly increase (from 214 to 226MB/s) and power consumption has reduced. Regards, Bart
Upgrade to WD30EFRX drives is failing
ReadyNAS Ultra 2 RAIDiator 4.2.30 (Latest) My old 3TB Seagates are failing so I am trying to replace them with WD WD30EFRX drives. The drives are supported according to the HCL (https://kb.netgear.com/20641/ReadyNAS-Hard-Disk-Compatibility-List?cid=wmt_netgear_organic) but they sure seem as though as they are not supported. I can hotswap drive 2 with a WD and let it rebuild the array against the old Seagate, but when I put a WD in slot 1, it won't start up. I just get the nas-XX-XX-XX boot prompt on port 23. This is getting a bit urgent as I am getting more and more SMART errors on the old drives. Can someone please help me?!?!?Solved

WD10EADS WD Caviar Green - 1TB >> excessive Load Cycle Count
I have two WD10EADS 1TB drives in my Duo. The first was installed a months ago as Drive 2, mirroring the 500 GB Seagate that came with the Duo. The WD drive seemed to work just fine, so I recently bought a second and installed it as Drive 1. In just a week of use, the newer drive is exhibiting a large and growing number of Load Cycles. After a little research, I found that the WD10EADS drive comes in a number of flavors. The first configuration had 4 platters (each approx 250 GB). A second variant had 3 platters. The latest vintage, which is the kind I just bought, has a pair of 500 GB platters. I am seeing vastly different behavior from the two WD10EADS units, as reported by the Duo's SMART reports. Drive 2: WDC WD10EADS-00L5B1. This is a 3-platter drive, installed in my Duo last month. - power-on hours = 1012 - Load Cycle Count = 670 - Power Cycle Count = 78 Drive 1: WDC WD10EADS-00M2B0. this is the newer 2-platter drive, installed last week. - power-on hours = 74 - Load Cycle Count = 3477 - Power Cycle Count = 10 The LCC value on Drive 1 increases by 2 or 3 every minute or so. I have my Duo configured to spin-down the drives after 10 minutes. Even so, the LCC continues to climb, even when the drives should both be spun down. I've done some web research and found extensive coverage of this issue at QNAP, Synology and Quiet PC Review forums. The root cause appears to be that the WD power-saving 'green' design parks the heads after 8 seconds of inactivity, while the Linux OS tickles the drive every 20 seconds or so, thereby unparking the heads. The Green series of drives are rated by WD for 300K load cycles during the drive's lifetime. Thus, there is some concern that the constant park/unpark operations will wear out the drive prematurely. One customer received back from Western Digital a troubling statement: ...The unit is not recommended for NAS or RAID use, due to its end-user design. But, under normal use, rather than strenuous or highly demanding tasks, there should be not much issue with the unit. Johnny T. Western Digital Service and Support I can't explain why my two WD10EADS drives are behaving differently. I can think of three possibilities: - the two different models have different firmware, and they park/unpark the heads using different algorithms. (note that both my drives have the same 01.00A01 firmware). - the two models are both parking/unparking the same, but are reporting differently through SMART. In other words, my Drive 2 also has large LCC count, but I just don't know it. It's been suggested by some experts that WD deliberately masked the actual operational statistics reported by some of their other drives in order to quell consumer concerns. - my Drive 1 is operating as the Linux boot drive, and is being frequently accessed by the kernel as the kernel goes about its routine tasks. But Drive 2 is merely a RAIDed data disk that does not get repetitive accesses.

Be aware that all such drives are not created equal: you need to know the full part number to know if you have a 4-platter, 3-platter, or 2-platter unit.Seagate 6TB Ironwolf (ST6000VN0041) Incompatible with ReadyNAS disk trays
I took a risk and purchased 4 x 6TB Seagate Ironwolf drives, Model #ST6000VN0041 and unfortunately the mounting holes for the disks are not matched with the trays that come with the ReadyNAS 314. Now I need to decide if I wish to ... Sand down the 2nd pin and only mount the drives using one screw and hope that the drives don't have any issues with the ReadyNAS OS Return the drives and go with something else. Pictures speak for themselves.... You can see by the lines I've drawn that the drives don't have the customary holes in the locations that most other drives do, and so they don't line up with the ReadyNAS tray: In addition, the black tray holder has two pins that slot into the screw holes on the sides of the drive, one pin lines up, but the other has not corresponding screw hole in the drive to use: Tray pins: Missing hole in drive for 2nd pin on tray:
