I deleted D drive in order to extend c drive but c drive will not extend

So I have 237gb of storage on my C drive and it is nearly full, my D drive has 931gb of storage and is completely empty. in an attempt to solve this problem I went online looking at different forums and articles and many recommended that I delete D drive
so i can extend C drive, but it will not give me the option after deleting it.

 

Deleted Disk Drive D

Hi S -

This is Orlando, an Independent Advisor and an expert with windows 10. I understand you're deleted your D drive to expand your C drive but the option is grayed out.

Is the C partition and D partition are on the same drive or disk?

how are you trying to expand the C drive?

If the drive D is a separate drive then extending the C drive will not be possible as they don't share the same drive volume. You can take back the D drive again by allocating it on your computer. To do that;

1. Open the disk management by pressing the windows key + r and type diskmgmt.msc

2. Once open, you will notice an unallocated space below which is the deleted D drive, you can just right click on it and select New Simple Volume. Follow the instruction next to re-allocate the drive D on your computer.

3. Once drive is created, it will automatically assign a letter on the drive and you can check it on the file explorer.

However if the D drive is on the same drive as your C, you can use the process below to extend the volume of your C drive;

1. Open command prompt with administrator access

2. Type DiskPart and press enter

3. Type List Volume and press enter. It will list all the volume created on your drive including unallocated space

4. Locate what volume number your C drive is allocated.

5. Type Select Volume X >> where X is the number that corresponds with your C drive.

6. Type extend and press enter >> partition C will be extended with the unallocated space on your drive.

Limitations of Diskpart to extend C drive :

* Only when there is adjacent unallocated space on the right side of the to-be-extended partition, extend command is valid.

* Only NTFS partition is supported to extend. Namely, the FAT32 or exFAT partition cannot be enlarged.

* Unallocated space is not displayed in the command window, so you don't know whether there is and where it is.

* Operations cannot be undone, the incorrect operation could cause data loss.

The above method should extend your drive C if it meets all the requirements needed to extend the drive.

Hope this help, have a good day.

Thanks,

No C: but D: drive has all the data

Hi Austin,

To help you with your concern regarding the data on the drive C:, you're seeing the drive "C:" as the drive "D:" because you're booting your computer outside Windows. When booting your computer outside Windows, the system is reading the recovery partition
as drive C: and the data in the drive C: \ are listed on the drive D: \. Try to boot your computer and try to check again the data in the drive C: \ and see if the data are listed.

Regards.
