Nowadays, we use computers in our daily life and work. Hence, we will store data on the computers. However, these files may be lost due to various reasons. Once the data gets lost, the first thing we may think of is to recover data using software.

There are many data recovery programs on the market. When you use them to recover data on the computer, there is a certain chance that you will fail. Why does data recovery software fail? This is the topic of this post. In general, you can refer to the following reasons.

Reason 1. You Have Full Formatted the Drive

When you format a drive on Windows using File Explorer or Disk Management, the Quick Format option or the Perform a quick format option will be selected in most cases. If these options are unchecked, you are performing a full format.

Quick Format just delete files. Therefore, you can recover these deleted files. However, Full Format will erase the original data, write zeros to the whole partition, and finally erase zeroes again to avoid the possibility of data recovery. Therefore, Full Format will cause data recovery failure.

Tip: If you use commands to format a partition, “format fs=ntfs” performs a full format, while“format fs=ntfs quick” performs a quick format.

Reason 3. There Are Bad Sectors on the Disk

When you write data to a disk, the unit is the sector, which is the smallest unit of a disk. A bad sector is an unreadable one. Upon taking damage, all information stored in that sector will be lost.

Bad sectors are classified into logical bad sectors and physical bad sectors. You can recover data from logical bad sectors using the chkdsk /b command, but you cannot recover data from the physical bad sectors with any data recovery software.

Reason 4. You have Password Protected the Disk

Why does data recovery software fail? Many people will ignore this factor. If you have enabled BitLocker on your disk, you cannot recover data from the password protected partition, unless you decrypt the disk first.

The reason is that the encryption has changed the codes of the data using its algorithm. If you don’t decrypt the disk, the recovered data is just a bunch of gibberish.
