Deleting data from a USB memory stick

Only one conclusion, therefore, can be reached: the stick is U/S.

. . . although it's odd that two sticks behave in the same way. But they are identical and were bought together.

Perhaps it's not odd at all: two identical sticks, presumably by the same manufacturer, from the same supplier, same capacity . . . etc. However, I would have been surprised if the same fault conditions had been found with two sticks which came from different manufacturers, different suppliers, etc.

Again, I don't wish to sound like a prophet of doom, but when you look at the available evidence from a distance . . .
