I have read the question in previous post about hard drive. I still not sure. I have a maxtor one touch 200 gig (model A01A200) that i only use for backing up data. I don't let it run unless it being use. Since i just got a imac (about 1 month) i need to back up file. (i have moved photo to imac, ect.) My question is should i reformat the drive for imac use only; for backup ect. Or should i get another hard drive for imac? is this is your suggestion please explain why? I would rather not buy another if i don't have to. 
thanks,
gean
