Hi Osanda,
Basic storage uses normal partition tables supported by all Windows versions right from MS-Dos, while a Dynamic disk storage has the feature that basic disks do not have, such as support for volumes spanning multiple disks, RAID 1 or RAID 5 disk arrays.
The downside of use Dynamic storage is that once the disk converted to Dynamic and being partitioned and used it cannot be converted back to Basic without losing data, as the Convert to Basic Disk option will be greyed out once it’s been used.
Follow these steps and check if this helps.
1. Open the computer management console. To open this console, click the "Start" button, then "Control Panel," then double-click the "Administrative Tools" icon, and then double-click "Computer Management."
2. Click the "Disk Management" heading in the leftmost pane of the Computer Management window.
3. Right click all volumes contained in the dynamic disk you wish to convert.
4. Select "Delete" from the context menu that appears.
5. Right click the disk after all volumes are deleted and select "Convert to basic disk." This will convert the disk and set it up for normal usage.
Note: Back up all data before you perform this task.
