Yes,ext3 provide journaling in linux.

there are 3 types of journaling provided by ext3

1) Journal-full journal mode,all data can be recovered.

2) Writeback-it only recover metadata(data about data),corrupted file can not be stored.

3) Ordered-recover metadata and specific file data.

Not all Linux partitions are ext3. It just happens to be the most popular file system. ext3 was created especially for Linux, so it is free from any patent issues involved with some other file systems.

ext3.

You would have to create a partiotion using fdisk or some other partition program.

then you can format it for ext3 file system

sudo mkfs.ext3 /dev/sda1

Quite simply, because Windows hasn't been programmed to recognise ext-type filesystems. Out of the box, Windows won't be able to identify ext3 and ext2 filesystems, and will probably consider them corrupted. Fortunately, you can install a driver for ext2 and ext3 filesystems into most versions of Windows. It's called ext2 IFS, and is linked below. With this driver installed, you can mount most ext-type partitions as ext2. (NOTE: ext3 is technically not supported. This means that using ext2 IFS will disable journaling, as that's the main difference between ext2 and ext3)
