# What happens to the fast drive when my Mac sleeps?

Normally the drive stays connected through sleep and is there when the Mac wakes. Storage Studio pauses its background checks during sleep and re-checks on wake, because drives may have changed while it slept. Drive-to-drive copies from Transfer Drive and Backup Drive resume automatically after sleep.

If the drive is missing after waking, click **Remount fast drive** in the popover, or unplug and reconnect it.
