How to Recover Data From a Corrupted Flash Drive Without Needing to Format

To fix a corrupt USB drive without erasing data, start by making a copy of the entire USB drive called a “disk image.” This copy includes all your USB data without keeping the actual USB connected to your computer. It’s like a backup that also helps prevent more damage to the drive.

Use a program like Disk Drill, which not only creates this disk image but also scans the messed-up flash drive to find and recover your data. Even if your USB drive isn’t showing up in Windows File Explorer, Disk Drill can still help.

It’s user-friendly, especially for folks who aren’t computer experts. And if you’re a Windows user, you can get back up to 500 MB of your data for free with Disk Drill’s trial version.

Step 1: Backup Your USB Drive

You can use Disk Drill’s Byte-to-byte backup feature to make a complete backup of your entire USB drive. Even if Windows is suggesting that you format the USB flash drive, Disk Drill can still access it and create a disk image. Here’s how to do it:

  • Download and install Disk Drill.
  • Connect your messed-up USB flash drive to your PC.
  • Open Disk Drill and click on the Drive Backup option in the menu.

How to Fix a Corrupted Flash Drive Without Formatting

Dealing with a corrupted flash drive? Here are three effective methods to fix it without resorting to formatting:

Method 1: Try Different USB Ports

  • Before attempting any fixes, connect your USB drive to different USB ports.
  • Prefer connecting to a motherboard-connected USB port rather than one on the PC cabinet.
  • If possible, try the USB drive on another computer to confirm the issue is with the drive.

Method 2: Repair the File System on Your USB

  • Windows comes with a built-in tool called CHKDSK to check and fix disk issues.
  • Type “cmd” in Windows Search, right-click on Command Prompt and run as administrator.
  • In the Command Prompt, type chkdsk X: /r (replace X: with your USB drive letter) and press Enter.
  • Reboot your computer after CHKDSK finishes scanning and fixing it.

Method 3: Fix Damaged USB Partition with TestDisk

  • Download and extract TestDisk, an open-source data recovery program.
  • Run testdisk_win.exe from the folder.
  • Choose whether to create a log file and select your corrupt USB drive from the list.
  • Select the partition type (usually automatic) and press Enter.
  • Highlight Analyse, press Enter, then choose Quick Search.
  • Press P to view recoverable files, then Q to return. Confirm P before the partition name.
  • Select Write, press Enter, then press Y to recover the damaged partition.

By following these methods, you can fix a corrupted flash drive without the need to format it.
