Part 1: Overview of "The File or Directory is Corrupted and Unreadable"

1. Major Symptoms of the File or Directory is Corrupted and Unreadable

Some of the most common symptoms of a file or directory is corrupted and unreadable Windows 7 are:

  • If you examine the computer's file system, you will most likely discover a RAW file format.
  • Whenever the location is not accessible, error 0x80070570 occurs, the file or directory becomes corrupted, and an unreadable error code appears, and you cannot access your machine. Most of the time, you may experience significant data loss.
  • When you decide to enter a storage device on a Windows PC, the error message 'H: isn't reachable' appears. (H is the drive letter of the unreachable storage device.)

If you do not resolve the issue as soon as the file is corrupted and unreadable, your information will probably be lost. You can repair the file or directory is corrupted and unreadable windows 10 with simplistic answers. Let's do it collectively.

2. Main Causes for The File or Directory is Corrupted and Unreadable

Though partition not reachable error is standard among many of us, the causes are unknown to most users. What caused this blunder? Overall, this defect will show up if a file, Folder, MFT, FAT, or USB drive is damaged for any reason. Let's get into the specifics.

  • MFT or FAT Corruption
  • The most common file systems used by Windows users are NTFS and FAT. So, what exactly is MFT? MFT is an abbreviation for Master File Table, which is the part of the NTFS file system, and plays a vital role in file storage. MFT entries contain all of the data about a file, such as its size, creation time, and application access. File recovery software can also restore lost data and analyze MFT details. As a result, if the MFT is destroyed, the system will not access information from NTFS partitions.

    On Storage devices and SD cards, the FAT partition (FAT 32/16/12) is most frequently used. FAT partition table monitors and processes data using the File Allocation Table, located at the beginning of a partition.

  • Virus Infection
  • Every day, people search through a sea of websites for all the information they require, such as tasks, study materials, enjoyment, and so on. People are encouraged to download or install malware on their computers while browsing the net. As a result, their computers are prone to virus infection. These viruses can delete sensitive data without warning, corrupt partition details, damage operating systems, and even infect other connected devices to the malware computer. When a virus corrupts the disk's file system, that particular partition becomes inaccessible.

  • Physical Issues
  • Another reason for an unreadable partition on a USB hard disk or flash drive is bad sectors. A bad sector is no longer usable or writeable as a result of persistent harm. Partition data, such as the file system, is saved in a particular location. If this location contains bad sectors, the user interface will be unable to access data.

  • USB Drives Are Not Safely Removed From PC
  • If you forcefully unplug a USB drive from a desktop while it is still in use, such as transferring or analyzing information, you potentially lose essential system files. Oddly, this is the most frequent cause of this error - a sound judgment that we all understand but ignore for ease.
