[SOLVED] Sierra Upgrade Wiped My External Drive

[dixdenni]

My Mac wanted me to upgrade to Sierra. I closed and ejected everything, but forgot to turn off my external drive. I'm missing 283GB of work documents, notes and files. How do I recover it? (And, of course, I'm freaking out.) Thanks.

Welcome to Tom's Hardware & sorry for the late reply, @dixdenni!

I'd strongly recommend you attempt to access the contents on the external drive from another Mac OS X computer and check if you will be able to see those missing 283 GB of work from there. I'd also advise you to go to Disk Utility on your Mac and try testing the external hard drive for defects from the tool.

If the files are very important to you and they are still missing, make sure you don't write any new data to the external HDD and contact a professional data recovery company for assistance.

Good luck! Hope this helps you.
