Reasons for Lost Partitions on Mac

After a disk is partitioned, a partition table is generated that helps the operating system identify the drive. If the partition table – usually referred to as the Master Boot Record (MBR) – becomes corrupted or damaged, the partition will become lost. This means you will be unable to read from or write to it.

• Certain malware or virus attacks are specifically designed to damage disk devices. Such threats can affect your disk and result in lost files and personal data.
• Data loss can occur if you make mistakes while partitioning a hard drive. Partitioning a hard drive is a sensitive operation, and an accidental formatting can delete the entire partition within seconds.
• If you're not comfortable with the terminal, there's a high chance of making errors while modifying partitions through it.
