@related: FileSystem ext4 ext3
http://www.fs-driver.org/troubleshoot.html
F:\>mountdiag.exe o: The volume has an Ext2/Ext3 file system, but the Ext2 IFS 1.11 software did not mount it because the file system has an inode size unequal to 128 bytes (inode size: 256 bytes). The only way to solve it is to back up the volume's files and format the file system: give the mkfs.ext3 utility the -I 128 switch. Finally, restore all backed-up files. After that, the Ext2 IFS software should be able to access the volume.
