Marco’s answer will get you that far. However… > (And then do a backup of my windows file with my rsync script to the external > harddrive.) …the e2fsprogs package isn’t going to get you a Windows kernel driver for ext3 filesystems, so you aren’t going to be able to mount the formatted filesystem under Windows. All you can do with e2fsprogs is write a fresh filesystem onto a block device and then run things like tune2fs to modify it in place. Cygwin generally leaves low-level filesystem issues up to the OS. The only filesystems Cygwin actually provides are virtual ones like /dev and /proc. I think you should be looking at something like Paragon ExtFS for Windows instead: https://www.paragon-software.com/home/extfs-windows/ There are alternatives, but I cannot recommend any from personal experience. I haven’t used Paragon’s Windows products, either, but I have used their NTFS for OS X product, and never had any problems with it. You might also consider going the other way: use NTFS on that backup drive to make Windows (and thus Cygwin) happy, then use fuse-ntfs3g on the Linux side to mount the drive. Either way you go, you’re going to run into semantic mismatches, such as permission mapping problems. That’s unavoidable. > For instance - I can not find fdisk. I don’t know about other extfs drivers for Windows, but Paragon’s includes a disk partitioning and formatting tool. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
