Just built a Windows 7 comp to go onto my home LAN and be accessed by all on the network, mostly running XP SP3.
Installed it as a single HD+DVD system, got it happy, then added my storage drives, set them up in the right order and letters, rebooted, and shared them. Couldn't access the computer at all from any XP machine. Set the pasword thingy in Windows 7 to NO, and now I can "see" all four shared drives from any machine, but can access only two of them.
Please tell me what's going on as I've done nothing different from one drive to the other, just installed and set up drive letters as normal, then shared the damn things.
The odd thing about it? The two 1.5T drives that have a lot of data on board are accessable, the two nearly empty 500G ones are not.
