This usually happens when the partition isn’t assigned a letter in Disk Management. Head over to Disk Management and check if there’s some space consumption for the partition. However, Disk Management might have a different say on this. Sometimes, File Explorer denies the existence of a particular partition. In Disk Management, if you hit a grey wall when trying to delete a partition, it’s undeletable. However, you can delete most of the other partitions. Some essential system partitions like recovery partitions, boot volumes, and OEM partitions are undeletable.

Therefore, a corrupted partition table would lead to partition loss. The partition table plays a vital role in describing the partitions to the OS.

As a thumb rule, always double-check before you confirm the deletion of any file. Unintentionally, deleting or formatting the wrong partition is among the most common partition deletion causes. Here’s a list of common culprits behind deleted partitions: To understand better, disk partitions (C: drive or D: drive) are subsets of a volume (HDD or SDD). Upon mounting a storage device, you are greeted with that sweet Windows notification sound and an alert saying, “USB Drive connected” – this is a volume. No, Volumes and Disk Partitions Aren’t The SameĪ volume is a storage device like a CD-ROM, USB drive, or a floppy disk formatted to store files and directories. When there isn’t sufficient contiguous space on a hard disk for storing a huge file (all chunks of that single file), disk fragmentation occurs-the OS stores different parts of the file at various scattered locations. The Master Boot Record (MBR) or the GUID Partition Table (GPT) is a particular location on the storage device that houses the partition table. Some standard file systems of Windows are:

Partitions usually have a file system that gets created on formatting a partition. Your computer loads and reads the partition table to identify which partition has an active operating system.Ī storage medium gets subdivided by the partition table, which uses units of sectors, heads, and cylinders. Windows maintains a partition table that describes all the partitions on a disk. As a result, you can even run multiple operating systems on the same device. Regarding the screenshot above, disk partitions are discreet sections of storage that exist independently. Resizing a partition is possible, but it could lead to data deletion. Here’s an ultra stripped-down and raw definition of a disk partition:Ī partition is merely a disk segment bearing a specific size set during its creation.

However, as long as this disk section remains untouched, the probability of recovery is pretty high. A partition deletion triggers the system to remove that location’s assignment on the hard drive, thus permitting this “new” memory section for overwriting.
