“In my efforts to fix my previous problem, I resorted to a fresh install of Windows 10 through the Windows Media Creation Tool. I have two drives: SSD for Windows-related files only and HDD for everything else. But I forgot both SSD and HDD are installed and accidentally deleted a partition on HDD during the step where I was to format the disk for a fresh install.
Now my HDD shows as Disk 1 in Disk Management, but as465gb of unallocated space and with no option to assign a drive letter. I haven't overwritten anything (I think), and formatted it. I would like to restore this partition and data within it. Is it possible?” – answers.microsoft.com
Accidentally deleted partition is one of the main causes of partition lose, as in the above user case. In addition, there are some other possible causes:
🧿 Corrupted partition table. A partition table stores information about how a disk is partitioned, including the size and location of each partition. If it's damaged(e.g. by a virus, or bad sectors), your partition may be lost.
🧩 File system error. If you use an Ext2 or Ext 3 drive on Windows, your computer will not recognize it, causing partition loss. Changing the file system for a formatted partition (e.g. from FAT to NTFS) also does.
🩸 Power failure. A sudden power failure may cause partition loss if you are performing any operation on it.
🎯Bad sectors. The computer may not recognize a partition with many bad sectors and display it as unallocated space.
🧺Accidentally formatted partition. If you format a partition, the space of it will be marked as "empty" and data in it is not visible.
🧷Loss of the volume label, drive letter, or partition name.
In fact, your computer recognizes a partition through the partition table and boot sector. When you delete a partition, your computer simply removes its partition information (eg: partition type, size, location, file system, etc.) from the partition table and makes it invisible instead of wiping it completely.
