Hey there, I am fairly new to MAC OSX, but very familiar with windows. I recently purchased a 300GB drive, diskutility in mac will not format it, i get errors such as input\output, ect., no matter what i try to do, however, in windows via parallels, i can format the drive as fat32 and bring it back to the mac and use it perfectly fine, although i want it in a MAC format instead of FAT32. What could be causing the HDD not to format in the MAC OS, but perfectly fine in Windows (via parallels)? Anyone else have these issues? Thanks.
