External hard drive not showing up in scratch disk

Question

I'm on a MacBook air with 15g free space but it says there's not enough space on the scratch disk to make one contact sheet. So I've tried using an external scratch disk by plugging in a hard drive but it doesn't show up when I go into the photoshop menu to change the scratch disk. How do I change the scratch disk to an external hard drive?

Hi there,

Sorry that your external drive is not getting detected in Photoshop as a scratch disk.

Which version of Photoshop are you using and on which operating system?

Would you mind checking the file format of your external drive and have you tried formatting it?

Thanks,

Akash
