Looking for help or similar experiences before I give up on this data.

Setup:

• Single-drive WD My Cloud Home, 4 TB
• Firmware: 9.9.0-102 (current)
• LED status: healthy (solid white)
• I have a second My Cloud Home that works fine, so my account, network, and client apps are all good

The problem:

• Device shows online and accessible via mycloud.com, mobile app, and WD Discovery
• I can see all my video thumbnails and folder structure
• Every single download attempt fails with: {"key":"notFound","message":"Not Found"}
• Storage shows 3.7 TB free of 4 TB — but the drive should have been essentially full (~3.6 TB of videos)

Timeline:

• Drive was full and working fine before the April 2023 WD security incident
• Haven't used or touched the device since then (about 2 years)
• Plugged it back in recently and discovered this state

What I've tried:

• Power cycling and full reboots
• Verified firmware is current
• Confirmed account ownership and login
• Tried multiple clients (web, mobile, desktop) — same error on all

My read: The thumbnail cache and metadata database survived, but the actual file data is gone from the disk (the ~300 GB of used space is consistent with just OS + thumbnails + index). Looks like something wiped the user data partition during or after the 2023 breach recovery, while leaving the index intact.

Questions for the community:

1. Did anyone else experience data loss tied to the 2023 incident that only became apparent later?
2. Has anyone successfully recovered data from a My Cloud Home in this state — either via WD support or professional recovery?
3. Given the device-bound encryption, is professional recovery even theoretically possible here?
4. Any chance WD has server-side snapshots from that era that support could restore from?

Any insight appreciated. Not optimistic, but want to exhaust options before accepting the loss.
