Yesterday, I shared a post on how to recover data and file-structure from a corrupt SDCard. The solution works perfectly for cases where the card/disk has Backup "file-system Boot sector" intact, but what if both get corrupted? Well, in that case we are left with no other option than to bypass the "file-system registry record" and "Scan" the SDcard to find and recover maximum data possible or somehow manage to fix the corrupt "boot Sector" record of the file-system.

After reading yesterday's post, one of our reader contacted me for a fix to this exact problem where both Main and Backup boot sector records are corrupted as shown below. Here is a guide on how to recover maximum data possible in such situation.
