NO.
The shutter type, unless it physically prevents you from putting the disk
into the drive has no effect on reading nor writing. You should look at
the multitudinous other reasons why Teledisk can't handle it, specifically
things such as Teledisk (SOFTWARE) can not possibly read anything that is
single density (FM), GCR, or with other physical incompatibilities.
After the original NO shutter diskettes (I have some made by or for
Shugart), and real manual shutter diskettes, there were some "automatic"
ones which required you to manually open the shutter (with practice, it
can be done by rapping the corner of the disk!), but have a spring and a
latch. When you want to close the shutter, pinch the corner (where the
arrow points, and or says "pinch"), to release the latch. Later diskettes
kept the arrows that pointed to the PINCH spot, even though they no longer
had a latch.
