RECOVER Data from Blocked USB Sticks, too !

...Some 18 Month ago, I was received an 1Gb USB Stick, I was fited it, with some Software Folders BackUps, and, AFTER having USED IT, for Re-Installing the inside Software some 3-4 times, presently I MAY NOT access the Needing Software's BackUps, and I don't know the "How to" Technology for UnBlocking it !
...Shouldn't be USEFUL to IMPROOVE your Stellar Phoenix CD - DVD Recovery, so as to RECOVER, the Blocked USB-Discs, too ???
I'm NOT the "only" one, UnHappy OWNER of "such" BLOCKED USB Sticks !

Have the GREATEST Success !
