A USB drive partition may disappear after accidental deletion, failed formatting, unsafe removal, partition table damage, or virus infection. When this happens, avoid writing new data to the USB drive because new files can overwrite recoverable data.
Step 1. Connect the USB drive directly to the computer instead of a hub.
Step 2. Open Disk Management and check whether the device appears as unallocated, RAW, not initialized, or without a drive letter.
Step 3. If the USB drive makes unusual noises, disconnects repeatedly, or shows the wrong capacity, stop using it and consider professional recovery.
Scan a lost USB partition first and save recovered files to another disk before recreating the USB partition.
Step 1. Open Qiling Deep Data Recovery and select Fast Scan first.
Step 2. Select the USB drive or the lost partition area that matches its capacity, then start the scan.
Step 3. Wait for deleted, lost, and existing files to appear. Use filters if you need only documents, photos, or videos.
Step 4. Preview found files and select the data you need.
Step 5. Save recovered files to another disk, not back to the damaged USB drive.
Create a new partition on the USB drive after important files have been recovered to another location.
Step 1. Open Qiling Disk Master and locate the USB drive by capacity.
Step 2. Right-click the unallocated space and choose Create Partition.
Step 3. Set the partition size, drive letter, and file system. Use exFAT for large files and FAT32 for devices that require broad compatibility.
Step 4. Click Proceed and wait until the partition is created.
For a lost USB partition, recover files before rebuilding the partition. Once the data is safe, create a new partition and format it with the file system required by your device.
