Is it possible to have an external hard drive and connect it to both of my computers (emac and a pc)? I would like to access information from both computers.
If your hard drive is formatted using the
Fat32 file system (Not NTFS) then you will be able to read
and write files using the drive on both systems. OS X can read but
not write to NTFS volumes.
You can format the drive correctly using Windows or from Apple's disk utility using the MS-DOS (FAT) Option.
You'd likely find it worthwhile to purchase MacDrive for the PC; that will make the drive faster (especially on the Mac) and will alleviate the need for any tricks formatting a large drive as FAT32. (Also very handy for using an iPod with both Mac and PC.)
