If you are not able to format the drive, then you can use the drive as a backup drive and backup your information. Apart from repartitioning your hard drive you might be interested in reading this article thoroughly.
It's more or less easy to follow and gives you some additional information. I just googled - there are tons of articles on the web,so I just picked one for you. I just noted this thread, as it has been a long time, but through the method above it is not data protective way so it is better to choose like AOMEI Partition Assistant or Gparted live CD, it could allow you extend the C partition without data loss.

MiniTool Partition Wizard is a professional partition manager, skilled in partition and data recovery, partition and disk backup , disk health test , etc.
Here is the step-by-step tutorial on how to recover data with MiniTool Partition Wizard when the D drive does not show up on the computer. Buy Now. Step 4: You will see a new interface where all detected disks and partitions are displayed. Scroll down the interface and double-click the drive that included the disappearing drive from the Hard Disks section.
Step 5: The software automatically starts scanning the selected disk and find the lost data. Wait patiently. Step 6: When the scanning finishes, select the data you want to restore and then click the Save button. Try MiniTool Partition Wizard. Click to tweet. After recovering all the needed data, you can create a new D drive if the original drive was deleted and you need one for storing personal data.
Here take using MiniTool Partition Wizard for example. Step 2: Right-click the unlocated space on the disk and then choose the Create option. Step 3: Choose partition type, drive letter D , file system, etc. If the D drive was swallowed by the C drive and you need a second drive for saving files, you can shrink the C drive.
The whole process is:. Step 5: Click the Yes button to confirm this change when you see a prompt as the following screenshot shows. C: without overwriting itself, and in part so users are less likely to accidentally delete it. My advice to you, Gilbert: Leave your D: drive alone. If it has a few extra gigabytes of available space, you could probably house some data there — but why risk it?
Apart from C drive, many people like to create a D drive or to create many other drives to store personal files and install apps. They think this method can benefit computer in the following aspects:. What are the theoretical bases of these reasons and are these reasons still reasonable today? Let's discuss them one by one. Can creating D drive improve computer performance? This saying is partially right. As we all know, HDD storage is composed of platters. Each platter is divided into tracks and then the tracks are divided further into sectors.
The data is stored in sectors in the unit of cluster; each cluster is composed of several sectors. Look at the following picture. The red circle is a track and the purple section is a sector.
When the data is written to disk, the data is divided into fragments clusters and continuously stored into disk. However, due to the frequent need to modify files, delete and rewrite files, the files cannot be continuously stored in continuous clusters of the disk anymore, but are stored in different places on the entire disk.
This is file fragmentation also called disk fragmentation. When there is no fragmentation, reading a file only needs the head to seek track once. But when there is file fragmentation, to read a file, the magnetic head needs to seek tracks multiple times. Moving apps and files to D drive can reduce the read and write operations to C drive, reducing disk defragmentation.
It is necessary to defrag computer since it can improve computer performance largely. This post shows how to defrag Windows 7 step by step. At that time, due to the limit of the file system, the size of the partition is limited, for example, FAT32 file system doesn't allow the partition to exceed 32GB in Windows Disk Management. How to break FAT32 partition size limit? In that case, C drive is also not more than 32GB, so moving apps and personal files to another drive is a very useful method to avoid C drive being full and reduce disk fragmentation.
In this way, computer performance can be guaranteed. However, the situation changed when NTFS and later file systems came out. So, you can create a C drive large enough to accommodate system, apps, and files. As for disk fragmentation, there is so much free space in the partition, so disk fragmentation can also be reduced effectively.
In addition, when SSD came out, due to its read and write mechanism, the worry about disk fragmentation became no longer important. SSD doesn't need disk defragmentation. And then, they move apps to the D drive.
This way is not recommended, because this can only improve PC boot speed. When you run apps, the speed is not improved, because these apps are on the HDD. Are there useful tips? This post will explore all the questions. Can creating D drive make computer maintenance easier?
This saying is absolutely right.
