I am setting up a new AEBS w/ external drive (Seagate Free Agent pro) to my mac G4 and HP PC. Wireless connection is ok but I received the msg. "Disk Needs repair--connect the disk to your computer to repair the disk" This sounds like a formatting isuue but I have done a lot of research was told by the Apple store (each of 3 visits) and in forums that I could see a PC-formatted drive when networked through the AEBS!!!!!!! (not older versions of AEBS though) --Any new advice on this? Has anyone received this error msg? --Also, If I have to reformat the drive, the apple store said I could use the HFS+ and PCs will be able to read/write to the drive. Is this the case? I'd like to avoid FAT 32. Any experience with HFS+ used by PC? thanks for any help out of this long learning curve.
