Ok had major issues with Lumia 820 which I got yesterday, as I wanted to upload my contacts and ringtones and music to the phone, now reading the guide I thought this would be so straight forward, insert the USB cable and bingo should sync straight away, well the fun begins.
Inserted said cable and found phone but that was it came up in explorer but couldn't see anything, well after trolling all the web sites and saying you need Net framework, Zune, this software that software, and after doing all these things still no go, so tried a different laptop with W7 and installing some more software still had same problem, so now thinking it must be the phone.
Removed battery, done hard reset (thanks Nokia for loosing my photos) still nothing, then removed Sim card still no go, then removed the the SD card and BINGO the phone would sync.
So it would seem if you have a SD card inserted then the phone won't sync this as wasted hours of my time just to get this to work.
Put the SD card back into my old HTC and that would sync ok.
Perhaps Nokia would like to comment.
Sorry to hear of this. First off, this is a user to user support platform so if you want to address this with Nokia I suggest you contact your local Nokia Care.
Losing your photos honestly is not Nokias fault in any way. You have the option to have them synced to the SkyDrive attached to your MicroSoft Account and they might even be there.
Whether or not this is an issue with the phone or maybe the SD card (what make/type?) is another matter, but as this would seem to be an isolated incident I would not be to quick to blame Nokia for this.
And your Lumia 820 will not require Zune at all, You need to have Windows XP SP3 or later installed for MTP to be available which is what is used to make the phone available in Explorer. No additional software required.

The newer version/s of Nokia suite does that rajaradi.
