About NTFS partition loss

NTFS (New Technology File System) becomes the mainstream for Microsoft's Windows operating systems to store users' data because of its overall benefits. This standard file system is for Windows NT, Windows 2000, XP, Windows Server, 2008, Windows Vista Windows 10, and Windows 7.  

NTFS is primarily optimized for Windows to increase speed, performance, disk space use, reliability, etc., compared to alternative file systems such as FAT or HPFS.

Unfortunately, even contemporary file systems like NTFS have their disadvantages. NTFS file systems may still be damaged. You may delete the NTFS partition by accident or the partition gets lost for kinds of reasons, so how to attempt NTFS partition recovery?

Common causes of NTFS partition loss

With the wide use of NTFS partitions by more computer users, the possibility of NTFS partition loss would increase accordingly. Normally, NTFS partition loss is caused by the following main four reasons:

▸ Partition table corruption or damage.
▸ Users’ errors-partition gets deleted or lost by mistake or improper operation.
▸ Bad sectors/tracks in the partition.
▸ Operating system or file system corrupted.
▸ Unexpected power surges.
▸ Interruption of resizing partition.

All of the above reasons could lead to computer hard disk partition loss. However, after users found the partition is missing, is it possible to recover NTFS partition in Windows 11/10/8/7?

Is it possible to recover the NTFS partition in Windows 11/10/8/7?

The answer is yes. The NTFS partition and data can be recovered. After the NTFS partition is deleted or lost, it will be marked as an Unallocated space in Disk Management and become inaccessible. The entire partition can be recovered in some cases.  Unless you reformat the partition, then you can reuse it, which means all data on the partition will be erased clearly. 

The chances of success depend on how long the partition was deleted or lost and what drive has been used. Stop using the drive until the data are recovered. In this case, you’d better use a reliable partition recovery tool-AOMEI Partition Recovery Wizard to restore the entire deleted NTFS partition. Before attempting NTFS partition recovery, you'd better not do the following:

Do not reformat the partition or hard disk.
Do not make any new operations on the disk.
Do not add any new items to the partition.
Do not rebuild the partition table.
