Reasons and Solutions for RAW Disk Partition

When a hard disk partition becomes RAW, users will not be able to access the disk and its data. A RAW disk partition shows several indications like file system of the drive/partition will appear as “RAW” instead of NTFS or FAT, Windows screens different error messages such as “you need to format the disk before you can use it”, “cannot access the disk the partition is RAW” etc.

In such situations, the user cannot access the drive/partition easily. So, here are the troubleshooting techniques to fix RAW disk partition. But, before getting started with fixation, let’s know why a disk partition becomes RAW first.

  1. Causes for RAW Disk Partition:
  • Virus Intrusion

The most common reason for a disk partition to turn RAW is virus/malware attack. Harmful malware damages the partition table of the disk that has partition information. Hence the partition becomes RAW.

  • Corrupted Partition Table

Improper usage of the disk, failed disk conversion etc. leads to partition table corruption in hard drives. And, this corrupted partition table is very likely to make the drive RAW and inaccessible.

  • Damaged File System

While dividing the hard disk into partitions if any interruption like the power surge, system crash etc. occur in mid of the process then file system of the drive gets damaged. As we know, drive partition is completely dependent on its file system. Hence, if the file system’s internal structure gets damaged, partition becomes RAW.

  • Bad Blocks

Bad blocks/sectors are defective space on hard drive and they are usually created by software issues, frequent power surge, improper usage of drive etc. So, the presence of bad sectors in the key area of the hard drive makes the drive faulty and turns into RAW.

  • OS Reinstallation

While upgrading the old operating system to the new, file system of the partition may change from FAT to NTFS or vice versa. If so, there might be a chance that the new file system may fail to get identified by the operating system. And, it shows as RAW.

  • Improperly Configured Access Permission

If the access permission of the partition related to local security policies is not configured properly, then the disk partition will display as RAW to restrain the access.

So, these are the main reasons for a RAW disk partition. Now, let’s see how to repair the RAW partition.
