My earlier message was appropriate for internal or eSata drives, but because I wrote it from memory instead of recording the steps and feedback while actually doing the work, my message contained some inaccuracies. I'm writing this message as I go along, so hopefully, it'll be more accurate. Internal disk. . . When DiskMgmt.MSC executes, it detects the UnInitialized internal disk immediately and opens an Initialize Disk window. By default, the new disk is selected, as well as a partition style. Simply click the OK button. Initialization is instant, and the window closes. Before initialization, DiskMgmt.MSC displays the disk with a red down-arrow, Unknown, its size, Not Initialized, and Unallocated. After Initialization, DiskMgmt.MSC displays the disk icon without the red down-arrow, as Basic, its size, Online, and Unallocated. At this point, the rest of the process is the same for both an internal drive or if we'd plugged in a Clean USB drive. Clean drives appear in Disk Management as Online, Removable (if it is), and Unallocated. Right-click the area where it says Unalocated and choose New Simple Volume. A Wizard will take you through the process and offer to format the drive. You can pick sizes, file systems, a drive label, and letter. If you choose Quick Format, the Wizard finishes in a second or two. I hope this clears any misunderstanding. Cheers, PW. P.S. I assume anyone using an SSD would have it installed internally, so it would act as a non-removable disk. A USB connection would throttle the SSD so severely, it would not provide any performance advantage over a much less expensive magnetic disk drive. However, an SSD in portable enclosure would be far more robust machanically than a magnetic drive and could prove useful in extreme environments. P.P.S. For today's experiment, I used Windows 7 Ultimate, 32-Bit.
