My Helix drive stopped mounting in my Mac. What should I do?

Open Disk Utility (Applications > Utilities) and click View > Show All Devices. The Helix should appear in the left column under External. An indented item should appear below it. If the item is greyed-out, it indicates possible corruption. Click the item and select First Aid to repair the volume. If it does not complete successfully, and it is formatted as exFAT, connect the Helix to a Windows computer. A corrupted exFAT drive can almost always be repaired in Windows. The Windows ExFAT repair tools are much more robust than Mac. Simply connect the drive and right click, select Properties > Tools > Check > Repair.
