What does convert to dynamic disk mean?
Conversion of a drive letter from basic to dynamic.
The difference between the two disk types is related to how your system can access them. Basic disks are internal or external hard drives that you must manually assign a drive letter to and which must be accessible at all times in order for Windows and other applications to work properly. Dynamic disks can operate independently of any assigned drive letter, and they store data on up to 32 individual volumes, allowing more flexibility when it comes time for management or maintenance. It’s similar in some respects to GPT partitioning on your computer’s hard disk drive, but on the level of an entire volume instead of just one partition. All FAT-formatted hard drives are initialized as basic disks by default, but any drive letter you assign—even one from a dynamic disk—can be changed to an NTFS partition on your original hard drive.
