For a disk storage device, the subdivision of a track is called a sector that stores a fixed amount of data. Typically, magnetic storage media, like hard disk come formatted with general industry standard of 512-byte in sector size. However, disks up to 4,096 sector size are also available. In the context of basic disks used in Windows Server 2003, Microsoft suggests disks with 512-byte in sector size. The dynamic disks are found to be compatible only with disk using 512-byte sectors. When you encounter issues related to disk sector size, you might need to change disk sector size that causes data loss. Thus, data backup will be required to restore the lost data. But, if in case, no valid data backup is available, it is recommended to use an efficient data recovery utility that could locate and restore the data.
To illustrate such issues, consider that you use a Windows Server 2003 based computer. You try to use Diskpart utility to convert your MBR or GPT disk to dynamic disk. The operation fails and you receive the below error message:
“The disk management services could not complete the operation”
When you attempt the disk conversion through the GUI, you come across below error message:
“The operation did not complete. Check the System Event Log for more information on the error”
You cannot convert the disk even at subsequent attempts.
Cause
Such errors root from larger disk sector size. This occurs if disk sector size is larger than 512-bytes. Since Windows Server 2003 dynamic disk supports only 512-bytes sectors,if disk is using sectors that are larger than 512 bytes, it will fail to convert to dynamic.
Solution
To correct these problems, you need to reformat and recreate the disk using 512-bytes sector size. The process will provide several single volumes each of 2 TB in size.
After the process is done, you will need to restore lost data from backup, which if unavailable or invalid might create issues. To recover data om such conditions, you need to use a powerful data recovery software. Incorporated with high-end data searching algorithms, these data recovery products serve as valuable tools to scan, locate and restore lost data.
