I have 3 computers at home: pc, iMac and Macbook air. The IMac has 2 external drives attached: one by FW800, formated as HFS+, and another by usb, formatted as NTFS. This was the usb drive attached to the pc, it contains all my media, and I used it as a server to access multimedia files on wireless lan. I now have it connected to the IMac, as the pc is now seldom used Problem is, my Macbook air can't see this usb shared drive on IMac and I can't figure out why, either as guest or as registered user with admin permissions. The fw800 external disk is seen. On System preferences -> Sharing I added the disk as a shared folder, put everyone with read & write permissions, and shared it using AFP and SMB. Strangely enough, Vista 64 on the pc can find the shared disk (SMB I guess) without any problems. What I'm I doing wrong? Thanks.
