About three weeks ago, I used my E drive to backup the files and "My Document" placed in C drive. Every week or so, I would backup all files from My Documents on C drive to My E drive. However, last night, I was trying to do the same but got an error message telling me "The disk in drive D is not formatted, do you want to format it now?" I cannot access the files and my backed up My Document files in E drive. Should I just say yes to formatting it and not worry about it?
One day, you might also find the drive with so much precious data in it becomes inaccessible out of some implicit reasons. Users can not access the files in the drive via File Explore, and when they access the drive, Windows will pop up a window, asking you to reformat the drive. Of course, please DO NOT format the drive, or all your valuable data will be lost.
The most reasons for the inaccessible drive are the file system parameters data on the disk have been damaged. With our data recovery software, you could easily recover your lost data with the following steps:
Step 1: Download and install EaseUS free data recovery software just like you do with any regular program.
Step 2: Launch the data recovery software and then please choose "Complete Recovery" to recover your data in inaccessible drive.
Step 3: After the file type window, select the inaccessible drive you like from the device list window, and then click "NEXT" to start the scanning.

Step 4: After scanning complete, please choose a file system and be free to click "NEXT" to reach the result window.

Caution: Don't save file(s) to the partition or drive where you are recovering data, for it may result in overwriting data and permanent data loss!
Back up your data with free backup software.
