I found out that tar is now coming bundled in Windows readily, so naturally I tried to use it to read tar contents from an LTO tape. However the seemingly correct command
tar -b 512 -vtf '\.Tape1'
reports
tar.exe: Error opening archive: Failed to open '\.Tape1'
even though I can confirm from the Windows device manager that my tape drive got the symbolic name Tape1 as shown below:

Is my syntax wrong with the command or what gives?
Edit: I downloaded build of gnu tar for windows from here: https://gnuwin32.sourceforge.net/packages/gtar.htm
and that one complains tar.exe: Cannot open \.Tape1: Permission denied even when running as administrator. What could cause this error?
