If you are using Ext2 or Ext3, you can convert the partition to Ext4. Ext4 uses journaling, checksums and write barriers and is therefore more robust against damage. | If you are using Ext2 or Ext3, you can convert the partition to Ext4.

Reiserf was the first journaling filesystem to be included in the standard kernel. It was actively used by some distros some time ago, but is not currently widely used. Reiser4 is the successor to reiserfs(3). However, Reiser4 seems not to be integrated in the kernel yet. | Reiserf was the first journaling filesystem to be included in the standard kernel.

Currently there are some restrictions when using NTFS with Linux. If windows is suddenly switched off or goes into hibernating, the NTFS file system is left in a "dirty-state". When Windows starts again, NTFS is the first to be cleaned. This operation is currently not supported by the Linux driver. Then Linux shows the NTFS file system as read-only to be on the safe side. | Currently there are some restrictions when using NTFS with Linux.
