Please help. I changed my laptop harddisk because my previous one was failing. Now I tried using the old one as external harddisk so I can copy out my files. The harddisk shows USB mass storage ready, the light is on but I cant see the harddisk partition on my laptop.

Please i need help on hw to retrieve my datas. I really need them

You can please try to check the disk management and see how the old hard disk works. If there is no problem with the hard disk, you can try to give a drive letter to the hard drive. If it doesn't help, give a try with some third-party software to clone the hard disk.

Thanks for sharing the nice post and you can give a try with some third-party backup software. Here I recommend AOMEI Backupper for Windows users. It's much easier to get all the data in your PC backed up. It includes several backup methods as well as incremental & differential backup, real-time sync, make a scheduled plan based on weekly, daily, monthly and so on.

Thanks for the tips and it's very useful. But in the daily working life, you could use free backup software AOMEI Backupper to protect your data and system from the ransomware.

Thanks for sharing, another free partition software AOMEI Parition Assistant has the same functions easier and more simple.

Windows built-in tool Disk Management provides users to convert disk to GPT with Windows interface. But if you want to use the command line to convert disks, the DiskPart can provide a terrace. However, both Disk Management tool and DiskPart utility can only convert an empty MBR disk to GPT. To change a disk from MBR to GPT with cmd, you can following the steps below:

Before you do, there are some tips for you:

Backup the MBR disk that you want to convert into GPT disk in order to keep the data safe.
You can only convert basic MBR disks without any partitions or volumes into a GPT disk. If there are some partitions or volumes, backup the data, then, delete all partitions or volumes before converting.
If you want to convert MBR to GPT disk during Windows intsall, please open command prompt by pressing Shift + F10.
Step1. Click Start, type "cmd", and right click it, select "Run as Administrator", or press "WIN+R", type "cmd" and press Enter to open the command prompt. Then, input "diskpart" to run the utility.

Step2. Type "list volume" to make sure if there are any partitions or volumes on the MBR disk which will be converted to GPT. If there are, you need to use diskpart delete partition first.

Then, type "list disk", and press Enter, it will show you all the disks on your computer. Make note of the disk number that you want to convert to GPT disk. Here take disk 1 as an example.

Step3. Type "select disk 1", press "Enter", it will remind you that the disk 1 is selected.

Step4.Type "convert gpt", press "Enter" to submit the operation. Wait a second, you will find the Command Prompt says DiskPart successfully converted the selected disk to GPT format. Please take a look at the following screenshot.

Can you could provide the screenshot of the disk management showing on your OS? But if you are Windows user, you can try some third-party software to merge all the unallocated space into the partition. Recommend the free aomei partition assistant, you can manage your hard drive with it.

Thanks for the detailed explain. I usually use third party software to create a system image with incremental backup per week. It's safe and quick. I recommend aomei backupper but it only supports Windows OS.

What are dynamic disk and basic disk?

Basic disk: A kind of physical disk which can be visited by MS-DOS (Microsoft Disk Operating System) and all Windows-based operating systems. It can contain up to 4 primary partitions or 3 primary partitions and 1 extended partition which contains several logical partitions.

Dynamic disk: It is also a kind of disk whose function is similar to that of the primary partition on basic disk. However, it can split or share data between or among disks. For example, a dynamic disk actually can consist of the storage space which is separated on two single disks. Besides, dynamic disk can copy data between or among disks in case of certain disk damage. This function needs more disks, but it is more reliable.

Why convert dynamic disk to basic disk?

Windows users know that there are two types of disk, basic disk and dynamic disk. Basic disk is the common disk and it can only be named with 26 letters. Different with basic disk, the dynamic disk is overcoming all the limitations. It has unlimited number of volumes, and it can be extended to other disks. Considering the advantages of dynamic disk, many users want to use the dynamic disk to replace the basic disk. However, for many reasons, users need to convert the dynamic disk into basic disk. For example, if there is a USB flash drive which was made into dynamic disk in Windows XP, it can be read by the Windows XP system. However, when you move this USB drive to Windows 7 system, it is invalid and it cannot be read. Why? Clearly because of the different disk types (some Windows operating systems do not support dynamic disk like Windows 98/NT, MS-DOS and all Microsoft operating system Home editions, Vista Home Basic Edition, Windows 7 Home Basic Edition... ). To solve it, you need to convert the dynamic disk to basic disk.

Windows Disk Management has the feature to convert basic disk to dynamic disk and vise versa. Convert the basic disk to dynamic disk is very easy and simple, but convert dynamic disk to basic disk isn’t easy. So, what if you met the same problem as the scenario shows "Convert to Basic Disk greyed out"?

How to Convert Dynamic Disk to Basic Disk Without Data Loss?

Note: In case of data loss results from accidents due to wrong operation or other unexpected factors, you’d better have a backup of your data. To do this, AOMEI Backupper can help you.

Step1. Launch AOMEI Partition Assistant and click Dynamic Disk Converter in the Wizards column on the left.

Step2. In the new pop up window, click Next to continue.

Step3.As you can see from the following screenshot, there are two options:

Method 1: Convert a dynamic disk back to basic disk. Safely, directly and time-saving (only take 3-10 seconds) revert a dynamic disk back to basic disk without losing data.

Method 2: Convert any dynamic volume to basic partition. Sector by sector clone simplified volume, spanned volume, striped volume, mirrored volume and RAID-5 volume from dynamic to basic disk.

Since we are going to convert a dynamic disk to basic disk, we simply choose Method 1. (If you need to convert a dynamic volume to basic, then you can choose the Method 2.) Then, click Next to go on.

Step4. Tick the dynamic disk which you want to convert and then click Next.

Note: You can tick to check if the selected disk contains mirrored volumes (RAID 1).

Step5. Confirm your operation and then click Proceed. Notice that you should tick “I have decided to execute this operation, click Proceed to start, the process only take 3-10 seconds” before clicking Proceed to show that you have confirmed the related information.

Step6. AOMEI Dynamic Disk Converter will notice you as soon as the operation has been completed. Click OK -> Finish to end this operation.

Note: To ensure the conversion take effect, it will restart the computer, so do not surprise by the sudden shutting down of your PC.
If your desktop or laptop cannot load Windows 10/8/7 successfully, you can install this software on another working computer. Then create a bootable media with a USB flash drive or CD.DVD to boot the other computer that fails to boot.

Except converting dynamic disk to basic drive, partition assistant can also convert partition between primary type and logical type, convert system disk between MBR and GPT Styles, Convert Data Disk between MBR and GPT Styles and so on.
