Obviously, there is something wrong with a USB memory stick when it is not accessible, unreadable or need to be formatted. Things could be worse when the USB drive can't be formatted by Windows because it is written protected or something. If you are dealing with such a USB issue, you can attempt to use Apacer USB3.0 repair tool to get it fixed.
The Apacer formatting utility is released by the digital storage brand to repair USB flash drive, including but not limited to Apacer AH325/AH328 and other AH1xx, AH3xx, and AH5x models. It has been proved effective to repair corrupted, write protected, RAW USB drive when other methods failed.
Apacer USB3.0 repair tool is going to repair your USB drive by restoring or formatting the drive. Both ways will erase files storing inside the drive. Therefore, it is important to back up everything in the USB drive before running the Apacer formatting utility on the drive.
If the USB drive won't open or you can't copy files from the drive, you can use FonePaw USB Data Recovery to back up files from USB drive to Windows or Mac computer. The recovery tool can recover existing and deleted data from the problematic USB flash drive to protect your data. So if you are looking for a method for USB flash drive repair, this tool suits you. FonePaw is free to download.
There are two buttons on the Apacer USB tool: Restore and Format. Restore is to restore the USB flash drive to factory status, which will wipe the USB drive and get it back to the original factory configuration. This is the "low level format".
Format is the last resort. By clicking Format, you format the USB drive with a file system (FAT/NTFS) and completely destroy the data on it, which is usually effective in fixing corrupted or write-protected USB flash drive.
Note: There is still a good chance for FonePaw Data Recovery to recover data from USB drive after restore, while it is difficult for any data recovery tool to get the data back after format.
