Overview of Drive is Not Accessible

Sometimes hard drives, external storage and USB flash drives can be affected by viruses or power failures, rendering them inaccessible by Windows. If the disk has become corrupted in any way, reformatting the partition can be a quick fix. However, all data on that partition will be erased during the reformatting, which is a problem if you want to recover the data.

As the ‘Drive is not Accessible’ error doesn’t allow you to open any files on the disk, you are not able to back up the data stored there. So, you’ll want to hold off reformatting the partition until your files are safe.

Should you have already reformatted your drive and lost the data, you still may be able to get the files back. When you delete something on a PC, the files aren’t actually destroyed, but the space they occupy on the disk is made available to the system so it can write over them. it’s very important then that you don’t use your PC at all, as writing anything to the disk could overwrite your files. Instead, download the EaseUS hard drive recovery software and use it to recover formatted partition data.
