Hi DKM,

Reseating the hard drive often helps. We have a tutorial here that shows how, and includes some other troubleshooting tips:

Your drive likely looks quite a bit different (I'll have to update this tutorial), and would be opened by removing a couple screws then sliding the case open. Feel free to give our tech support line a call tomorrow if you need assistance.

If you've ever received another drive from us in the past and reseating this one didn't help, you could try moving the 2017 hard drive into one of your older enclosures. If the drive is OK but the enclosure has stopped working, this should get it to show up.

If you do get the drive to show up, I'd highly recommend copying your songs to the Mac HD right away (the Documents folder is a good place to save your work). External hard drives fail a lot more frequently than internal ones (since they get moved around and disconnected), so aren't the safest place to keep your project files.

Thanks
