Usually novices tend to look in My Computer first, and if they do not see a drive, then they give up and assume the dock or the computer is faulty. On occasions, when the drive came out of a satellite box, or a PVR, and it contained non-DOS partitions, then Windows 7 will not assign a drive letter and you will not see the drive in My Computer. I have noticed that on occasions when the drive contained non-standard DOS partitions it can still be a problem. For example if the drive came from a Linux computer, or Unix computer, then Windows 7 generally does not provide a drive letter, and therefore there will not be a drive showing in My Computer. Unfortunately, this is just not the case and one has to consider where the drive came from and what type of partition and file system it has. Many novices tend to think that they can plug in any drive with any partition structure and any file system, and Windows 7+ should show them the drive with a drive letter in My Computer. Having used this unit for many years on Windows 7, I have noticed that on occasions one does not always see the disk drive in My Computer.
