I removed Windows 10 from my 240GB SSD to use Ubuntu 21.10 as default system.
But I can't read a partition in my 1TB HD which I created using Windows.
The partition I am referring is was on a 1TB HD which I used only to store files. The partition files simply disappeared and now it is named as "Windows" inside Ubuntu with parition type "LDM" (?).
What is the best way to get access to this partition?
sudo fdisk -l
. Omit all of the /dev/loop entries (those are snaps). Post the (complete) remaining entries in your Question above. The information we need to answer your question is in that output.
