You need to format the disk in drive before you can use it

Usually, if you frequently force unplug your SD card, USB, external hard drive or any other removable device without using the Safely Remove option, the partition table of the device will be corrupted and become RAW which is unreadable by Windows. And then you might receive the disk format error message "You need to format the disk in drive X before you can use it. Do you want to format it?" when you try to access the storage device. However, it not the only reason that may lead to the format disk error. There are other reasons including:

  • The storage device suffers from a sudden power outage
  • The storage device is infected by a virus
  • The file system of the disk is not Windows-compatible
  • There are bad sectors in the USB flash drive, SD card, memory card, or external hard drive

Frequently Asked Questions

1. Why choose EaseUS Data Recovery Wizard?

"EaseUS Data Recovery Wizard is the best we've seen. It's far from perfect, partly because today's advanced disk technology makes data-recovery more difficult than it was with the simpler technology of the past, but it's fast and efficient..."PCMag

2. Why cannot I recover 2GB data for free?

It is recommended to check the version installed is Free or Trial because they are different versions.

Trial has data preview function but cannot save any files, while the Free version enables to recover 2 GB files. The default free space is 500 MB and you may share the product on social media to get another 1.5 GB.

3. Why cannot the recovered files be opened?

A file is saved as 2 parts on the storage device: directory info (which is comprised by file name, time stamp and size info, etc.) and data content.

If the files with original file names and folder structures cannot be opened, one possible reason is the corrupted directory info. There is still a chance to recover the data content with the RAW Recovery method in our software.

The storage structure of the lost files would be altered or damaged by any changes on the drive. If you save the recovered files back to the same drive, the original data structures and data content would be corrupted or overwritten, which causes permanent data loss. So you should prepare another disk to save the files.
