Problem description:
“I received a warning “You need to format the disk before you can use it” when I opened my USB drive. Then, I viewed the properties of the USB flash drive and found out it is 0 bytes in Used space, Free space as well as Capacity, as shown below.”
Are you experiencing the same problem as the user above? Is it possible to retrieve data from the USB drive showing 0 bytes? How to fix the 0 bytes drive error?
Right now, to perfectly repair the drive showing 0 bytes, we will introduce what is a 0 bytes drive and what causes this to happen at first.
Error – USB Drive Shows 0 Bytes
When a drive shows 0 bytes, it is sometimes because the drive space is unallocated. Or, the file system of a drive will display as an unknown file system or RAW file system (Windows system cannot recognize them). Many devices can suffer from the 0 bytes error such as USB flash drives, pen drives, memory cards, external hard drives, etc.
And, if you try to access data saved in the 0 bytes drive, you may get the following error:
1. You need to format the disk before you can use it. Do you want to format it?
2. The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.
3. The type of the file system is RAW. CHKDSK is not available for RAW drive.
Why Does USB Flash Drive Show 0 Bytes
Many reasons can cause this error, including:
- Unplug the USB drive when transferring data.
- Remove the USB flash drive without clicking “safely remove hardware”.
- Power outage while the disk is writing data.
- The drive is infected by a virus, so its file system is corrupted and displays as a RAW file system.
- There are some bad sectors on the drive, which will cause problems in saving or reading data.
