how to test Tech 2 memory card ?

Today I want to talk about the Tech 2 memory card. I do not fully understand how to test. In fact, it's not always, but sometimes he gets a bad card, visually tells him not to say anything, even puts them in Technology 2, and they will be loaded. But on some menus, Tech 2 Scanner will only restart. I started it from the menu on the device, especially in the hardware version. There is a 99% chance that he will hang in engine data block engine data 1 ... 3. Not always, but sometimes he wrote ADDRESS ERROR - PROCESSOR HALT. Later I bought another card, it did not hang, and then I copied the software to both have the same version, eventually worked normally with only 1 card, or other periodically rebooted the device or just all hanging, help off - Turn off the car diagnostic scanner Tech 2.

Here's a photo of my bad card that may still try to solder. Who knows things are worse because it obviously doesn't. Yes, it is best to use any notebook or desktop PC with a PCMCIA to cover the card, because Tech2 scanner are often time consuming and not a complete success story.
