Ext3 on Windows
Note that newer versions of ext3 use 256 byte inodes by default, which makes them unreadable with Extfs (at least to version c). Make ext3 filesystems with the -i 128 flag to retain compatibility. Other Windows software such as Acronis backup are also affected.
Another option is to use colinux which runs under Windows and allows you to mount any Linux filesystem.
Also, There are other userspace tools which can be used to access ExtX partitions from Windows
- Ext2read This can be used to view/copy Ext2, Ext3 and Ext4 Fs. It also has LVM support.
- Explore2fs Application to read Ext2 Ext3 Filesystem.
