I recently purchased an external hard drive compatible with Time Machine.  I understand this application serves as a backup system.  I am beginning my first year of teaching this fall and also need to keep a few copies of all of my teaching materials.  Can I still use the external hard drive as a storage device (more like a flash drive)?  How do I go about this and use it for both?  Or should I just use it more like a flash drive for the purpose of keeping copies of my teaching material?

    I would suggest if you are using the EDD for both Time Machine and your data that you partiotion it.

     

    Remember when configuring the sizes for the partitions that the partition for Time Machine should be at least 3 times the size of the disk being backed up.

     

    The downside to this solution is that Time Machine will not be able to backup the data,

     

    If you need backup coverage for this data I would suggest you get another EDD for you data instead of the partitioning.

    Welcome to Apple Support Communities

     

    Of course. You can use the external drive to make Time Machine backups and to store other data. The only thing you have to do is to create two partitions on the external drive through Disk Utility > http://pondini.org/OSX/DU3.html

     

    After doing this, you will have to use one partition for Time Machine, and another one to store your files. It's important to make Time Machine backups, as they allow you to restore the whole system if the hard drive fails. See > http://support.apple.com/kb/HT1427

    Do not do that. Dedicate a disk drive for backups and no other use. Get a second drive or a flash drive to transport changed files back and forth. Or simply get a second external drive for your storage needs.

     

    I stand opposed to Allan's and mende1's proposition of partitioning the backup drive. If that drive were to fail then you lose not only your backups, but your other files as well. Keeping them separated is the best strategy against catastrophic data loss.
