Netgear ReadyNAS Duo VEEEERY slow and can't be mounted in Windows Explorer
Hi, I've got a readyNAS Duo with firmware 4.1.16 since a couple of years that contain large quantities of very important information. If it did not I would have given up long time ago. 1st c...
Your consistent need to re-sync on boot (which is likely causing all of the boot issues you note) is not normal. You likely have a bad drive. . You can check just the system log in the GUI and drive SMART to see if that tells you, but the downloaded logs might better help you figure out which one is the problem. Mounting each in a PC or USB dock connected to one and running the manufacturer's diagnostic tool on each should also help.
It is possible that you have a bad bay in the NAS, but it's more likely just a drive, so check them first.
Thank you very much for your response Sandshark!
The Frontview admin interface is nolonger available (no new logs can be pulled out) and I can nolonger acces the web interface to access the content of the disc. RAIDar indicates the NAS is still synchronizing several days after.
So all I have are the last message in the logs mentioned in previous message "IO error" and "SATA reset".
Assuming the problem is indeed the drive - then what should I do to be able to access my data?
I'd be very interested in knowing how I could mount the drive on a PC (URL to manual?).
Thank you

One option is to power down the NAS, and then connect the drives (one at a time) to a Windows PC either with SATA or a USB adapter/dock. Then test the each drive with vendor tools (Lifeguard for Western Digital; Seatools for Seagate).
Another way is to power down, remove one of the drives, and then power up again. You won't get any more resyncs (since that requires two disks), but the NAS might not boot either. If it doesn't boot, replace the drive and remove the other one - then try again.
If the NAS does boot, offload the data right away. You might get some errors, but copy everything you can. (If you do get errors, you can try booting off the other disk, and seeing if you can get more files off).
One tip - label the drives by slot as you remove them. That ensures that you can put them back in their original position. Also, make sure the NAS is powered down when you remove the drives or add them back.
