I have four 3.5 " hard drives & one 2.5 " laptop hard drive. All are formatted NTFS. I have a Thermaltake Docking Station. I just put the 2.5 " laptop drive in & Mavericks didn't complain. I think that OS X can read NTFS, but not write NTFS, right? FAT32 is readable & writable by OS X, right? OS X will format a drive to FAT32, right?
