I NTFS formatted a brand new WD 2TB drive and populated it with data using a Windows XP 32Bit system. The drive now had a remainder of 283GB useable. I hooked the drive up to a Windows Vista 64Bit system. Diskmanager shows the drive as healthy and the appropriate size. I was unable to access or view the data and a I/O error occured. Am I missing something, should I have initialized the drive when hooked up the Vista system?
