I have a PC running Windows 7 Ultimate and a 2TB Buffalo external HDD where I keep all my personal media.
Under XP, I shared the entire disk and all of its subfolders on the network and accessed my pics and movies via my Apple TV.
Under Win 7, that is no longer the case. Upon reboot, any previous shared settings are gone. If I want to access my media from the Apple TV, I have to recreate the share and all is well... until the next reboot.
My NAS drive has no trouble at all. It's only my Buffalo DAS drive and Windows 7 that seem to be having this issue. The Buffalo DAS drive has its own power source and is always on. So, I don't think it's the drive.
Any experts out there who can help?
