If you lost partition or delete an important partition by mistake, you can use the AOMEI Partition Assistant software to easily get back lost partition in Windows 10,8, 7.
Typically, we need to partition a storage device into one or multiple partitions before it can be used to store data. Partition is a piece of area for keeping the operating system and personal data. If one partition gets lost, deleted or corrupted, you will be unable to access all files in that partition. No users want to suffer such an issue. However, partition might get lost due to many factors including:
▸Improper operation during OS installation: when you asked whether to keep the previous partition on hard drive during system installation, you choose NO and partition gets deleted. ▸Abrupt power outage: the power failure can cause various issues to partitions, and one might be partition loss. ▸Virus infection: if the partition is infected by the virus, it can also get lost. ▸Bad sector: a hard drive that contains bad sectors might become empty. ▸Drive letter loss: if one partition does not have a drive letter, this partition will not show up in Windows File Explorer. ▸Clean command: when you execute a “clean” command on the hard drive in Diskpart, the partition will be deleted and the files will be erased as well.
Many users might wonder if it is possible to get back lost partition. Actually, that mostly depends on the real culprit behind the partition loss issue.
