So I lost a 256k DISK that had a lot of stuff on it, thankfully I still have the disk_manager.dat file in my save's data folder. I've tried looking at disk_manager.dat with NBTExplorer, and it's not obvious what I'm looking at when I open the diskuuid entry. Thank you for reading this.

Give yourself a DISK with the same UUID as the entry in disk_manager.dat. Join the AE2 discord server if you need more help

Thank you very much!
