My post was not answered on someone elses's thread so I thought I would create another one. I originally had my external hard drive formatted to NTFS, but found out that it would not read on my iMac, so I formatted my external through disk utility to MS-DOS (FAT 32). My iMac is recognizing the external hard drive, but my windows computer is not. I want to transfer some files from my Windows PC to my iMac using my external hard drive, but windows just won't recognize hard drive now that it is formatted to FAT 32. Any suggestions on what I may be doing wrong? Thanks for the help!!!
