Ext4 partition loss issue

Partition loss is a common issue to computer users, as many reasons can lead to this issue. Here are some common causes of partition loss:

  • Partition deletion: mistakenly delete a partition in Disk Management or partition manager software
  • Disk formatting: you may format or reformat an entire hard disk, after which all partitions and files on that disk will be lost.
  • Repartition disk: repartitioning hard drive wipes hard disk first so that new partitions can be created on the disk.
  • Partition table error: once partition table gets damaged or become invalid, partition information may get lost or corrupt, and the consequence is partition loss.
  • Bad sectors: in some cases, hard drive with bad sectors may become unallocated or empty in Disk Management. If you open partition manager DiskGenius, you can see there is no partition on the disk.
  • System reinstallation: when you reinstall operating system, you may be asked to make choices between many options which may include the one that is able to wipe everything on the disk. If you select wrong option, you’ll suffer partition loss after system reinstallation.
  • Factory reset your PC: many brand PC provides the feature which enables users to reset the device to factory setting. This process restores computer or tablet to the state it came out of the factory. Thus you’ll lose all data on the local disk.

Here is a real case about Ext4 partition loss issue:

I have a removable hard drive which contains two Linux partitions using ext3 and ext4. This morning all partitions on the disk are lost, I mean the disk is raw and had no partitioning and no partitions. I assume the partition table got damaged since last time I used it on my laptop. My laptop had problem ejecting USB mass storage device, and I had to unplug it directly. I haven’t recreated any partition on the disk for fear of overwrite the data. My laptop is running with Windows 10, and I hope lost Linux partitions can be restored under Windows.
