Recovery of files
Hello all,
I have an older RNDU2200. It seemed to be operating correctly until about 3 years ago. At that time, access to the drive became intermittent, but I always managed to find a way to connect. I didn't access the drive for 2 years, and when I tried recently, I found that I could not connect at all. I've tried with an older Windows 10 and newer Windows 11 OS laptop, and I've tried all the tricks/recommendations I've read here on the community site, including adjusting the SMB settings and addressing directly via \\NAS-xx-xx-xx.
I've lost prior versions of the RAIDar app, which was the only way it worked in the past. The latest version can't see the drive when connected as a network resource and I even tried to connect directly from the PC to the drive via USB, detached from the network. No joy. Is there a way to get older versions of the RAIDar app ?
Otherwise, I've reached my troubleshooting limits.
I don't want to continue to use this unit, but I would like find a way to access the drive just long enough to get the files off.
What recommendations do you have ?
Any advice/guidance would be greatly appreciated.
Many thanks,
Erick

An Ultra 2? What firmware is it running?

It's possible that the hard drive(s) have failed.
Can you connect to the NAS web ui? (https://nas-ip-address/admin) ? Using the real IP address of course.
Use Firefox, and set security.tls.version.min to 1 so you can use TLS 1.0 (needed since otherwise current browsers won't connect). Browse to about:config and search for the setting.

You can't connect to the NAS using USB. You can put the disk into a dock. Windows won't recognize the format, but there are RAID recovery tools you can use. Which one depends on what firmware you are running.

The latest version of RAIDar will work with your NAS, so you have another issue. Does RAIDar show the NAS if you boot it with the drives removed?
