Sometimes, you need to be able to read a Linux filesystem from Windows. Either you are dual-booting, or perhaps like me you are trying to get some data off some old hard disks that have been in a box for a couple years.
There’s a handy driver that will mount ext2 disks on Windows available from http://www.fs-driver.org/. Install it, and when you have attached the drive, use the Control Panel “IFS Drives” item to select a drive letter for your volume.
Works great, and transparently in Windows.
