Format Disk to Solve The File or Directory Is Corrupted and Unreadable Issue

If a disk check doesn't work, you can try to format your external hard drive or USB drive to solve the issue. Format configures hard disk with a new file system, after which the corrupted or damaged file system will be replaced. 

However, as we all know, the disk format will definitely cause data loss. Therefore, to settle the file directory is corrupted and unreadable issue without any data loss, we highly recommend you recover your data from your hard drive before format.

Recover Data from Unreadable Hard Disk First 

Download and use EaseUS free data recovery software to recover data from external hard drive, USB flash drive, SD card, and more devices with only 3 steps.

Step 1. Run EaseUS Data Recovery Wizard, choose the external hard drive or USB drive where you lost data. Click the "Scan" button to find files.

Step 2. The software will start immediately to scan all over the selected drive for all lost data. During the scan, you could see more and more data showing up in the results.

Step 3. After the scan is over, you can preview the file by double-clicking on it. Click "Recover" and choose another location to save the recovered data.

Format the Unreadable Hard Drive 

After data recovery, you can begin to format the inaccessible hard drive. You can format the hard drive in Disk Management or using EaseUS Partition Master. 

Windows Disk Management doesn't allow you to create/format a partition to FAT32 when the partition size is larger than 32GB. What if you want to format your hard disk partitions to the FAT32 file system for use on PS4? Use EaseUS Partition Master, which can help you do it without limitation.

The File or Directory Is Corrupted and Unreadable Causes 

We provide detailed information for users who want to figure out why the file or directory is corrupted and unreadable error happens. Here we list 4 common reasons. We hope it is helpful, and you can take caution with awareness to avoid this error. 

Cause 1. MFT or FAT Corruption 

MFT is short for Master File Table and is included in the NTFS file system, containing all the information, including file size, creation time, and access permissions. Like MFT, FAT (File Allocation Table) is included in the FAT file system. It tells the operating system where the file is stored. Thus, FAT or Master File Table corrupted error will disallow the system access data from the NTFS or FAT partitions.

Cause 2. Virus or Malware Attack

When your computers, USB flash drive, memory card get infected with a virus, the file system might be corrupted and show the file or directory is corrupted and unreadable error. 

Cause 3. Physical Damage

Hard drive, USB, flash drive, or memory card can be corrupted due to bad sectors or physical damage, which will cause your device to no longer accessible or writable. 

Partition information such as file system is usually saved in a specific location. If this location includes bad sectors, then the operating system will fail to access data. Then you'll get the file or directory is corrupted or unreadable error message.

Cause 4. Unplug USB Without Using Safely Remove Option

If you unplug a removable disk from the computer without using 'Safely Remove' while the drive is transferring or reading data, you will risk losing vital files system information. This is one of the most common reasons for the file or directory is corrupted or unreadable error.


It can be nettlesome when your hard drive has the file or directory is corrupted and unreadable problem, as it prevents you from accessing your hard drive and read the data. The issue can occur due to the causes mentioned above.

You can fix the file or directory is corrupted issue by performing disk error repair or hard drive partition formatting. And EaseUS Partition Master can help you resolve the problem with the easiest solutions.
