Drive Failure Cannot Access Data
Hi,
One of the drive lights on my ReadyNAs is blinking im guessing that means the drive has failed.
The display screen says "Recover data 98.61%"
I cant access the data or logon to the software.
If i just replace that drive will it finish recovering?
TIA

Will just pulling the plug hurt anything?
Holding the power button down for 5 seconds or so should also forcibly shut it down, so try that first.
If the unit is locked up (as it sounds like it is), you really have no choice but to do this. If it was just resyncing the disk (which could have failed while that was being done), then there shouldn't be any data loss. You can just remove that disk, and power up again.
Note that if another disk had a read error during the resync, then the resync would also fail. So once you've checked that the data is ok, then you should probably run a disk test from the volume settings menu. Then download the log zip file after that completes. Examine the SMART stats in disk_info.log, and look in system.log and kernel.log for disk and btrfs errors. If everything looks healthy, then you can hot-insert a replacement disk.

Don't replace anything just yet. I suggest installing RAIDar on a PC, and looking at the status there. https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar
Do you have a backup of your data?
RAIDar doesnt find any storage on my network.
I do have a backup. So i am not worried about data loss. Other than the hassle of pulling it all together again.
The blinking disk LED does mean the disk either has failed or is being resynced to the array. The panel message suggests a resync - though normally I'd expect the NAS to be accessible during a resync (and that RAIDar would also find it).
You could of course wait longer and see what happens.
Another option is to power down the NAS, remove the disk that is blinking, and then try to boot without it. If that fails, it's probably most direct to do a factory default and restore the data from your backup. Either way, I'd test the disk in a PC with vendor tools before adding it back (Lifeguard for WD disks, Seatools for Seagate).
