Read-only File System Does Not Allow Accessing Data From Linux Hard Drive

File system is a significant component of any of the computer operating systems. It keeps record of all the files and directories on the storage media. Linux operating system supports a series of file systems, which include Ext4, Ext3, and Ext2. Ext3 file system also supports journaling of the file system and thus considered safer than other file systems. However, under some circumstances, file system may get damaged and lead to severe data loss. At this point, Linux data recovery becomes need of hour.

All the files on storage media are managed in a hierarchy, called tree-structure. Root directory is the base of this tree and thus manages all the files and directories. Linux root directory is the origination of all the files and directories. File system needs to be mounted for accessing your precious data. If file system hierarchy faces any inconsistency issues, data may become inaccessible.

As a practical example of file system consistency issues with Linux file system, you may encounter the below error message while accessing data from hard drive-

“Remounting filesystem read-only”

Subsequent to the above error message, you may also face the following error-

“Detected aborted journal”

File system Journal file replays when it finds the inconsistencies with Linux system. In such situations, the file is aborted.

Root of the problem

The problem may take place due to any of the below reasons-

Computer hardware or hard drive is faulty.
File system is corrupt and operating system cannot read it.
The file system is forced to go in read-only mode in case busy I/O errors report disk as failed.

Resolution
You can try any of the below Linux recovery methods to sort out this problem-

Check system hardware. The problem usually occurs due to crashed hardware.
Reboot your system. It will help you fix the problem if it is caused by I/O errors.
Check whether you have device] [mountpoint] ext3 errors=remount-ro 0 0 entry in /etc/fstab directory.
Run fsck utility to check file system defects. It is inbuilt utility to check and fix file system defects.
Use third-party Ext2 recovery applications to thoroughly scan entire hard drive and extract all lost, missing and inaccessible data from it.

Such tools let you perform data recovery Linux in all data loss situations. They are totally safe and easy to use with read-only conduct and simple graphical user interface.

Stellar Phoenix Linux Data Recovery is the most efficient tool to recover lost data from Ext2, Ext3, Ext4, and FAT file system volumes.
