This must be done very quickly; the cable half way inserted when the selection is made and shoved home quickly. If you are fast enough the phone is recognized as ssd1 and can be mounted giving access to the microSD card.
Disconnection must be done by umounting the device. If the disconnect option on the phone is selected before the buffers are flushed the microSD card is left in an unusable state. I had to reformat it and start over. Fortunately I had transferred the entire content of the card to my pc because reformating the card lost my entire contact list. If you own this phone and select phone memory there is an option to transfer the entire phone memory to the card. I did this and then mounted the phone and used cp -r to transfer the entire contents of the card to my pc. When I crashed the card all the phone information was lost. It was recovered by the reverse transfer from the pc to the card and then, to be safe, I selected the phone's card memory and used an option to transfer everything back to the phone memory. If anyone is interested I am fairly happy with this phone. It capable of using but does not require subscribing to the Verizon database. Since I am retired and am included in my daughter's Verizon account I did not want to subscribe to the database running up her phone bill. So I have a touch screen phone with a lot of features. I have always wanted to preserve my contact information some of which is captured from incoming calls on my computer. This phone does that. It will play music and videos, mp3 not ogg, but I don't really want to use my phone for that, I have a Sansa player that plays both mp3 and ogg. It makes the hands free Bluetooth connection to my car. Too bad I can't play around with Android and write apps for the phone but with my other hobbies I might not have time anyway.
