What Causes Deletion of Data from Disk Partition on Windows Devices?

Before you proceed with the recovery of your lost data from the Windows partition, it is important to find the exact reasons behind it. Identifying the main causes of the issue help you to avoid such data loss issues in the future. Given below are some reasonable causes of partition loss on Windows devices:

  • Accidental deletion: Human errors, like accidental deletion of files from device’s hard drive, are one of the primary causes of data loss. This generally happens when you mistakenly delete files or format the wrong partition on your device. It is important to double-check every operation you are performing on your partitions and during deleting or formatting any data from them.
  • Software or hardware failures: There may be sudden system crashes, power failures, or hardware malfunctions which can corrupt the disk operations and causes data loss. Such failures can corrupt the partition table or the file system and make all the data on your hard drive inaccessible or lead to their deletion.
  • Operating system issues: Sometimes, problems within the operating system lead to deletion or loss of data on your device partition. For example, if you don’t have a proper Windows update or installed an incompatible driver, then issues like data corruption or deletion can occur within a partition.
  • Disk formatting: When you format a partition of your device, it erases all the data stored on it. It is important to have a proper backup of your important data before you format any partition or perform quick formatting of any partition.
  • Virus or malware attacks: If you have viruses or any malicious software in your system, it infects your device and causes data loss. This in result causes corruption or deletion of your files, including those within a specific partition. Make sure you have a reliable antivirus program installed on your device to avoid such data loss issues.
