    My phone is saying 'no memory stick inserted' and it wont be recognized by pc either, tried memory stick on other mobile and it works fine, so its not the stick. Any suggestions would be greatly appreciated.

    My memory stick went in the puddle and it got wet so i dried it and everything is fine the only problem with my phone is that it doesn't read the memory stick and i tried to dry sooo many times but still memory stick is not recognised and i know the memory stick is working fine because i have tried it on my dad's W850i and on my PSP.

    Any help will be appreciated!

    My W580i does the same. I tried inserting the memory card after formating using my PC, but still the problem persists. The same momory card in accepted by another W580i but not mine. I thought the software needs to be updated. It also failed to update with sony ericsson update service. Please guide me through this

    My phone tells me "memory stick not inserted" sometimes, and other times "warning! all content will be lost, format anyway?"

    If i say yes and type in the code, it says "memory stick formatted", then just goes back to telling me i have not inserted a memory stick

    If i say no it just goes back to telling me i have not inserted a memory stick.

    So it seems wheter i format it or not, it just doesnt think theres a memory card in there, tried in my moms phone and it recognized it soooooo

    please help

I had the same problem, I realised I must have got it wet from the above comments.
I basically took the card out and blew very hard into the socket in an attempt to dry it. I put the card in and it worked fine!
I hope this has helped, sorry if it doesn't.

Send all your documents to your pc, then format the memory card and put all your documents back to your memory card.tnx

SOURCE: w850i memory stick

hi there,
            I dropped my sony in water once and the screen stopped working completely , I had to replace the lcd screen myself in the phone, (which isnt that difficult with a sony ericsson , it damaged the lcd screen but not the rest of the this sounds like your software has been corrupted or the memory slot contacts have developed a fault from the damp
                                                                                          Try the master reset function (remember this erases any security pin numbers you might have put into the mobile) and see if the problem persists.If your brave enough ? like me ! you could strip the phone down and blow it dry with a hairdryer (set on low temperature), look for gunk on the memory card contacts and clean these off with computer solvent cleaner and a cotton bud.Then update the firmware and the software from sony ericsson's website.But I have a feeling , that the water got inside and this has coated one or more of the contacts for the memory card with the same thing , that you get inside a kettle,literally scale has formed on one of memory card contacts.
