I have ubuntu and windows 7 installed on 2 separate physical SSD's and I'm wondering how to turn off a disk once booted up.

If I select windows during bootup I want to shut off the linux SSD (to avoid wear and I don't want it running anyways) and vice versa.

Does anyone know to do this in both windows and ubuntu?

This question came from our site for system and network administrators.

The wear on SSD drives is from writing data. Reading or idling doesn't wear them down.

Windows won't mount Linux partitions that are formatted as ext2/ext3/ext4/xfs/btrfs or any of those other filesystems that Windows doesn't understand. And when running Linux, I presume you're not writing to the Windows partition on a regular basis. So it's really nothing to worry about.

If you reeeeaalllly don't want to write to a Windows partition when running Linux, you could edit your /etc/fstab file to mount the Windows partitions as read-only. If you want to do that, say so and I can add more details of how to do it.

If the disk is formatted with one of the ext filesystems windows won't recognize anyway and certainly won't be able to perform any operations that would cause wear.
