Hello,
I performed a clean install of Win 7 Ultimate 64-bit (via Technet subscription) a couple of days ago on a desktop which was running Vista Ultimate 64. Prior to the upgrade Zune 80 device (Firmware ver 3.2) and software (I believe it was ver 4.0) worked w/o problems in Vista. But after installing the Zune software onto Win7 and setting up the device , the Zune 80 will not sync music. I was able to sync some podcasts but it just won't do music. When syncing music files the status under the Zune icon first reads 3% then immediately jumps to 97% and that's it. The device summary displays "Not Added" and 'files not found' in the pull down listing. There are no error codes that display as far as I'm aware.
All my media files are kept on an external hard drive connected via USB2.0. One thing I did notice after Win7 was installed was the external drive displays the folders/files as "Read Only". I am still able to add and delete files from the folders however. I have changed permissions but it seems to have no effect on the drive folders or the syncing (sinking? LOL!) issue.
I have tried reinstalling the Zune software on numerous occassions, forgetting/resetting the Zune 80, ensuring all Win7 chipset, SATA, etc. drivers are installed from my mobo vendors (Asus) website. Since I am a Canadian Zune user I am presently downloading the Zune software from the '.ca' site as it is a considerably smaller file size (55MB) than the version posted on Microsoft's site which is 460+ MB. I am hoping this may make a difference.
I am pulling my hair out trying to resolve this and soon I will be bald. Any other suggestions would be greatly appreciated as I continue reading here and the interwebs.
TIA.
