How to fix external hard drive file system error 65535
Since the problem is related to the file system, you can use the CHKDSK utility, which helps you check the disk integrity and correct the file system errors on FAT (FAT16/FAT32) and NTFS drives. The Check Disk utility also marks the bad sectors, which is the most common cause for file system error and drive corruption.
CAUTION: Running CHKDSK on your external hard drive with file system error 65535 could be disastrous for the data stored on the drive.
During the check disk scan, if the utility finds bad sectors on the drive, it tries to repair those bad sectors, and if the sectors store some data, it most probably will be lost.
Therefore, backup your drive if you can as people experiencing this particular error are also not able to copy their files, and thus, the disk or data on it can’t be backed up.
In such a situation, you can use a data recovery software such as Stellar Data Recovery Standard for Windows that helps you recover your lost crucial data from such a drive that has encountered the error 65535. Therefore, if you do not want to risk data loss, skip to the data recovery process- explained below- before running the CHKDSK scan.
1. Perform CHKDSK
Press ‘Windows+S’ and type CMD
Right-click on the ‘Command Prompt’ and choose ‘Run as administrator.’
Assuming the connected external hard drive letter is E, type the following command in the command prompt window chkdsk /f /r E:
Replace letter E in command with the affected hard drive volume letter you see in File Explorer
Press ‘Enter’ on the keyboard (press ‘Y’ if prompted)
Wait for the chkdsk to scan and repair the file system and disk errors on your external hard drive that is showing file system error 65535
After it’s completed, restart the system and access your hard drive
Caution: As cautioned earlier in this blog, running CHKDSK — without taking prior data backup — may pose a risk of data loss in certain scenarios. Therefore, it is strongly advised to restore your inaccessible data by using the following steps:
2. Implement Data Recovery to Backup/Restore Data
Connect the affected external hard drive to the system
Download, install and run Stellar Data Recovery- Standard for Windows
Click ‘All Data’ and press the ‘Next’ button
Under ‘Connected Drives’, choose the affected external hard drive
Turn on the Deep Scan toggle switch that appears at the bottom left of the software window
Click ‘Scan’ and wait for the scan to finish
After the scan, the files and folders are listed under the left ‘Tree View’ pane
Click the ‘File Type’ tab in the left pane to sort the files according to their file types
Click on any folder to display the containing files and folders under the right preview panel
Click on any file to preview it and click the checkbox to select it for recovery
Select the files or folders that you want to recover
Click ‘the ‘Recover’ button
Click ‘Browse’ and choose a location on a different drive (with enough available storage space) where you want to save the recovered data
Further, if you want to conserve storage space, under ‘Advance Settings’, choose compression, which will save the recovered data at your desired location in compressed ZIP folders
Once the data is fully recovered, you can proceed with CHKDSK. Alternatively, since you have all the files and folders backed up with the help of Stellar Windows Data recovery, you can directly format the drive and repair it instantaneously. And later, transfer the recovered files to the original repaired external hard drive.
