The volume does not contain a recognized file system – RAW File System

By | June 1, 2017

The cause for Windows or Chkdsk failing to recognize the file system on a volume, mostly lies with file system corruption within the volume itself. Theoretically it also possible that an error in the partition tables or boot sector is the cause for the “The volume does not contain a recognized file system” issue.

As it is a file system problem, it can happen on hard disks, Solid State Disks (SSD), USB disks and SD memory cards etc.. In my experience removable disks have a higher chance of file system corruption than fixed disks.

Windows Disk Management will list the file system of the drive as “RAW file system” and may prompt you to format it. However, do not format the drive at this point! This is especially true if the volume is on a SSD drive as Windows will issue a TRIM command which will actually overwrite all data on the volume.

Although it is sometimes possible to repair the volume, I strongly recommend against it as it is very well possible you actually make the situation worse.

Typical symptoms and messages are:

  • You need to format the disk in drive before you can use it. Do you want to format it?
  • This 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.
  • Chkdsk can not be run on the drive

For both magnetic hard disks and SSD drives, in general chances for successful data recovery are good. As data was not lost due to deletion by a normal Windows procedure but due to file system corruption, Windows will not issue a TRIM command to the SSD.

ReclaiMe will normally almost immediately start populating the folder / file lists. You can already preview text and image files. You can also search for and save files (using the Save button).

Wait for the number of files in the left bottom corner if the windows to settle, you can pause the scan (usually 3-5% into the scan). See if the files you need to recover are listed and recover (Save) them. You can resume the scan if needed.

Software to repair a RAW volume:

Although it is sometimes possible to repair a RAW disk, it is not recommended. It can only work if damage is limited to the partition tables or boot sector. You need to have an above average understanding of partitions. Also, as repairs write to the disk, it is very well possible you make the situation worse.
