Issue: Encountered ‘The Disk Structure Is Corrupted and Unreadable’ Error
‘The disk structure is corrupted and unreadable error usually occurs while using external storage devices. However, it may also pop up while trying to open a partition on the internal disk.
Here’s one such illustration of the issue:
I have a 2 TB Western Digital external hard disk (model which needs a power supply). I worked without any issue for 2-3 years. I have used 95% of its space in the last couple of years.
While using the hard disk yesterday, the drive got disconnected suddenly and is no longer working. When I click it, it shows “O:\ is not accessible. The disk Structure is corrupted and unreadable”. I connected the disk to multiple laptops but the problems still persist. Can anyone help me fix this error so that I can restore my data?
Typically, this error occurs due to some problems with a storage device, such as:
- Storage media is corrupt
- The device is infected with the virus
- There are bad sectors on the disk
- The storage device is physically dead/damage
When this happens, you lose access to your crucial data.
