This makes such partition loss issues tough to prevent. Some common causes of partition loss issues are as follows:

• Loss or Damage of the Partition Table: The partition table is a crucial part of the HDD. Which is responsible for displaying the partitions. If the HDD’s partition table is damaged somehow, then the data inside it won’t be able to be read or written sequentially, thus causing non-operational issues. Such damage occurs due to malicious operations, software conflicts, power outages, hot-swap failures and virus attacks. Whatever the reason might be, you won’t be able to boot it into any other system successfully. A black or blue screen appears, suggesting that you cannot enter the operating system for some reason.
• Careless Operations: As per the famous saying that “Even Homer nods sometimes,” we all tend to make mistakes sometimes, even when we think we are being careful enough. For example, a user opens the Disk Management utility in MS Windows, tries to manage the HDD, and unintentionally a volume gets deleted. After this instance, disk space originally allotted to the volume that has been deleted turns into unallocated space.
• Virus Attacks or System crashes: A partition gets easily deleted when any computer system gets infected with viruses. The normal explanation would suggest that a system crash basically refers to that situation when your computer is not functioning normally as per the normal standards and/or crashing often. A system crash can happen anytime while shutting down the system abnormally or while upgrading the BIOS and installing programs mistakenly, which can, in turn, make the partitions disappear.

If any sector cannot be read or written normally, then it usually becomes invalid, and therefore, its corresponding track is then known as the bad track. If any sector or track is physically damaged by any scratches or stains, then the whole drive would become dead..
