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 connection attempt
When I rebooted the NAS a few days ago it first took ~1day before the LED stopped flashing (as always...). Q: is that normal behavior?
Then I tried to access it from my LAN network. That was not possible because the NAS had not received an IP address on the LAN and is not attempting to get one using DHCP. Device could not be detected by RAIDar tool and of course not be pinged since it has no IP...
Q: How to troubleshoot next time if I don't want to reboot and restart sync process?
After 3 days without success I decided to reboot the NAS. Not possible to reboot through the power button although I kept it pressed for a minute. Q: how to avoid button not working?
So I rebooted the NAS by unplugging the power supply (as always). Q: how to avoid this?
2nd attempt
After some time (15min) the NAS has received an IP address (observable on my router and device responds to ping but it's not visible in Explorer or by RAIDar). And after 1 hour it is detectable by the RAIDar tool and in Windows Explorer as a media server (but not yet as a storage media).Q: Is that duration normal?
Shortly after the device's front LED stops flashing. RAIDar informs "Volume is syncing". After yet some time the device also appears as a storage device in Explorer. I can now access the readynas frontview admin interface (https://<IP>/admin).
According to frontview there is a share for CIFS, AFP and HTTPS.
I can access the web interface https://<IP>/<name of my share>. But it is sooo slooow that I couldn't possibly use it to navigate through my files.
I would therefore like to add a network drive in my windows explorer.
I therefore use Map network drive as described in "Access a share from a windows device" in the manual https://www.downloads.netgear.com/files/GDC/RND2110/RAIDiator4-1_SW_en_06Dec11.pdf.
I select a drive and click Browse - but my NAS is not available in the list of network drives!
Q: Why is it not? How to troubleshoot?
I instead enter the IP address of my gateway - doesn't work. I also try enter the server manually (but can't find documentation of what URL to use). I have tried
\\192.168.3.15 -> Doesn't work that is not a valid name
\\192.168.3.15\media (IP + share name) -> I'm prompted to enter username + password. I enter admin + my password and it doesn't work (it claims I'm entering the wrong credentials).
\\192.168.3.15\shares(IP + shares (because https://192.168.3.15/shares is accessible through web interface) -> I'm prompted to enter username + password. I enter admin + my password and it doesn't work.
System logs show
- "SATA reset"
-"I/O error on channel ??"
-"Improper shutdown" (reasons explained in attempt1)
Could you please help me with this?
Thank you,
Lena

One practical option is to enable FTP for the NAS shares, and then install FileZilla on the PC.
If you are running Windows 10, then you need to make sure the SMB 1/CIFS client is enabled. You do that by going into "turn windows features on or off" on the PC. You will get a security warning - but you have to enable that client in order to connect to your rather old NAS.
Once you are sure that SMB 1 is enabled, reboot the PC.
Then you can try mapping the full data volume by running CMD in the PC. You enter
net use * /delete /y net use t:\ \\nas-ip-address\C /user:admin nas-admin-password
Use the real IP address and NAS admin password of course, and be careful on the typing. The spaces and the two different slash directions matter.
Note that command won't work if your admin password is still set to the default netgear1.
Thank you very much for your long response StephenB!
FTP is a very good idea (since all I want is a way to rip out all the content from the drive!) but right now the NAS Frontview page has stopped responding completely (page shows with look-and-feel but empty, without any textual content) so that is not yet possible (3 days uptime and NAS still syncing but nolonger responding to frontview or disc content web page :womanfrustrated:)
I have tried SMB enabling (it was already) and using the "net use" commands. But each time I get error message "network name nolonger available after typing the password".
I'd need to find another way to get out the data out of this NAS.
Do you have SSH enabled? While the sync may be keeping the GUI from functioning, SSH takes a lot fewer assets.
If you have a way to connect the drives to a PC (a USB dock is popular instead of using an internal SATA port), using vendor tools may help you determine if the problem is just one drive. Assuming you have a XRAID volume, you could try booting it with just the other one once you identify the bad one. You could even just try booting with each drive by itself. There will be nothing to sync, then. Note that if it does boot, you don't want to just put the other back in, as that will likely start the sync again. You should back up your data first, then try a new drive as the second one if you plan to continue using the NAS.
There are methods of getting the data off the drives using a PC or Linux system, but StephenB is more of an expert on that than I.
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.
