What should I do if the mobile hard drive is in a RAW format?

There are three solutions for this:

• Solution 1: modify the drive letter of the RAW drive. For example, if you have drives C, D, E, and F, with F being the drive letter for the RAW drive, change F to E for recovery.

• Solution 2: use the command chkdsk. Click "Run" → enter cmd → enter "chkdsk" (drive letter): /f, e.g. "chkdsk D: /f" for drive D, and then press "Enter" to execute.

• Solution 3: use restoration software, such as winhex and diskgenius.
