my external hard disk which is always attached to my mac takes very long to get recognized and appear on the desktop. sometimes as long as half an hour!? even though in my windows it doesn't take time at all. it's there instantly. is there any solution? i tried to replug the hard disk. change the port. tried my friend's hard disk and all the same. it seems like a problem with all hard disks not just mine. do u face any similar problems?
