An odd thing happened this morning.
I have the 1185, that I have set up with a primary boot drive on Windows 10.
I have two expansion cards, a 250gb that boots UBUNTU 21.04, and 1 Tb that I had planned to use as backup.
Upon receipt, both things worked, as expected. Both were initially recognized by Windows. After creating the Ubuntu dual boot, the 250 Gb was no longer seen by Windows (not a problem for me).
Starting yesterday, the 1 Tb disconnected and reconnected (File Explorer came up, showing the drive, without me touching anything).
Today, the 1Tb drive is not showing up at all for Windows, but booting Ubuntu, I can see the drive.
Removed the drive, attached it to a Lenovo with a USB-C port, this computer recognized the drive, everything I had copied was there.
Tried reformatting, on the Lenovo, no problems, then moved it back to the Framework. Windows still did not recognize it.
Any Ideas?
