HDD nice to look at but totally ineffective. Despite several messages for service of Western Digital, none of this answer. He was asked to format before use while talking about a record original formatting NTFS. Unable to save anything, I tried to format several times. Duration of operation: 9:00 format every time and in the end, Windows XP message announcing that the format could not do! Hoping to partition, I used PartitionMagic 8, but impossible to do anything: the hard disk is reported as "defective" when Windows declares it as "healthy"! ? In desperation, I sent the material to me fully refunded. Note the presence of a virtual disk drive containing a program of no use in my case and complexity of use unnamed and which has not helped to resolve the issue. This virtual disk is completely indelible and wastes space on the HDD. Why mandating that will not serve everyone? Very disappointed with this model while generally Western Digital creates excellent products.
