# Why does it say there isn't enough room on my fast drive before a move starts?

Before moving anything, Storage Studio checks that your drive has room for the whole item **plus a safety margin**. If it doesn't, the move never starts — so there's no chance of a half-finished copy.

### What to do
- Free space on the drive, or move something smaller first.
- Check the drive's free space in Finder (select it and press ⌘I).
- If you regularly hit this, a larger drive is the real fix.
