I've had to take a HDD out of my DLINK NAS and need to copy the data. I have a cradle that looks like this: https://www.amazon.ca/UGREEN-Converter-Adapter-2-5-3-5Inch-Supports/dp/B016JTH8FA/ref=sr_1_3?keywords=sata+to+usb+power&qid=1561347797&s=gateway&sr=8-3
When I plug it in, I only see a 524MB partition, and no data. It's a 2TB drive. Does Ubuntu not support ext3 format? Do I need to do anything additional?

ext2, ext3, ext4 are all supported.
However, was the drive taken out of the NAS that is part of a RAID? For instance, is it part of a striped RAID (0) opposed to a RAID 1 would be a complete mirror? If it is part of a striped RAID without the parity, it may not contain data that is supported because the writing of the blocks would contain partial fragments of data. Something similar to a bunch of corrupt data unless it is part of the same array as when the data was written to the drive.
EDIT: A couple of things to add to my previous note. If there was any corruption of the RAID pair prior to you removing it and attempting to read it as a single drive, the corruption would follow both HDDs of the RAID 1 configuration depending on which one was considered the master drive. Is there any possibility that you have failed to mention here that the hard drive you are reading from was from a failed RAID 1 pair?
A couple of links for sites that are part of your multi-stage question that may lead you into understanding what options you have that are specific to DLINK: http://forums.dlink.com/index.php?topic=65242.0 http://forums.dlink.com/index.php?topic=58580.0 http://forums.dlink.com/index.php?topic=41734.0
ADDITIONAL UPDATE: (from another article on the DLINK website)
Some additional steps may be needed due to the way RAID writes data to the disk. Please see the link: http://forums.dlink.com/index.php?topic=54559.0
In case the link no longer works, here are the steps that the original poster, ironcyborg, had posted. You may not be considering this a failed array, but the steps from reading from the drive shouldn't matter:
I'd like to share the procedure I used on Ubuntu 12.04 and ArchLinux to access data from a disk of a degraded RAID 1 created with a D-Link DNS-320L NAS.
The graphical way is really simple: you just need to
The command-line procedure is a little more complicated:
