Symptoms of Raw Partition

"Raw partition error" doesn't always happen, but exists indeed. It may happen to a local hard drive, external hard drive, USB, and other storage devices. It usually occurs with the following symptoms when the disk partition is corrupted or damaged:

  • Invalid media type reading drive. Abort, Retry, Fail?
  • The file system is displayed as RAW.
  • Windows may show "Disk not formatted. Do you want to format now?"
  • File names contain weird characters.
  • "Sector not found" messages.

A partition with the raw file system is inaccessible. When you encounter one of the above situations, unfortunately, you can't open the files such as documents, photos, emails, etc. on the problematic partition. If you have data existing on the partition and format the RAW partition directly, it will result in the loss of all the data on the partition.

So if the files are important, you can consider using a reliable disk data recovery software to recover the data first, then format it to make it work properly again.
