No more room on 1tb hard drive..what's best to do

The short answer is yes, you can split your music collection over 2 drives. But I think in your case that might not be the optimal decision, as it sounds like it would interfere with your backup mechanism at the moment.

Better would be to get a 2 TB drive and either a 3 or 4 TB drive. You can likely just take the drive itself and install into the existing enclosures by unscrewing a few screws and replacing the existing drives.

Copy one of the 1 TB drives into the 2 TB drives. Then make the larger (3 or 4 TB) drives the Time Machine, and ensure that it backs up the external drive. The difference is that this will give you a more complete backup and allow you to recover from deleted files, viruses, mistakes in tagging, etc. I also recommend an online backup service to guard against theft and fire

zd542, yes, I have done that. Most of my external drives are from OWC (macsales.com), and it amounts to a few Phillips screws and 3.5" hard drives. You're right in that the exact nature of the external drive needs to be taken into consideration as to how easy it is to replace it with a larger drive.

But yes, under the right circumstances (and understanding your equipment well), this kind of upgrade is do-able.
