Yes, a disc storage lock can be picked open, although the level of difficulty will depend on the specific lock and the skill of the person attempting to pick it. Disc storage locks are designed to be difficult to pick, but they are not completely impervious to picking.
Disc storage locks typically have a series of pins inside them that must be aligned in a certain way in order for the lock to be opened. A skilled lock picker can use specialized tools, such as picks and tension wrenches, to manipulate the pins and get them into the correct position to open the lock.
However, picking a disc storage lock can be time-consuming and require a lot of skill and practice, so it's not something that can be easily done by someone who is not experienced in lock picking. Additionally, there are other methods of bypassing a lock, such as using a key, using a bypass tool, or drilling the lock, that may be easier or faster than picking the lock.
