memorycard

One (may be two) of the most popular postings on this blog is about memory card locking. There are many people are asking me how to unlock password-protected memory card. The problem is they never put any password on it; and suddenly their memory cards are locked.

I have written two postings about memory card locking, i.e.:

Apparently, there are still a few cases where memory card is suddenly locked. My previous colleagues had this problem as well. What is the solution then? Unfortunately, I don’t have a good answer if the two tips above don’t work. My colleague tried to call the memory card’s manufacturer. They said that he has to send the memory card back to the manufacturer. I am not sure whether they will replace it with a new one or do "magic" to unlock the card. They also mentioned this case sometimes happen on certain devices.

Anyone has other idea how to unlock memory card?
