I got WDTV live with two WD HD (0,5 TB and 1TB). The 0,5 was FAT32 previously but I converted to NTFS with formatting it before. When it was FAT32 I could see in my home wifi network (router ASUS RT- N56U) on laptop with Windows7 64bit with no problems as a shared device. Immediatelly after conversion it has vanished, only 1TB which is still FAT32 I can see now. I tried everything on WD (reset, restoring factory defaults, re-installin the firmware ect), doesn’t work.
Ok, try to connect the drive that is formatted in NTFS to your computer, look for a folder named WD TV, delete that folder and make sure that you safely remove the drive from the computer, then try again to connect the drive to the WD TV.
I did as you said - exactly the same, again only FAT is visible. There were some problems at the begining during WD TV folder removal - one file seemed to be corrupted or damaged but I did it finally (may be the fact is meaningful) after having reboot my WIn. What else…i compared all credentials on both HDs, looks the same. The only difference is I can see FAT labelled with WD icon in my computer and ntfs is listed without it. I don’t know why - ntfs was formated before conversion from FAT, may be it lost some qualities? Kind of **bleep** indeed.
