External Hard Drive Not Appearing On Ipad Pro. Look in the column on the left to see if the hard drive appears there. Tap on Move and select the External Drive from the menu.
Check Apples Disk Utility to see if an external drive is showing up. Connect your external drive to your iPhone or iPad either directly to its Lightning or USB-C port for 2018 iPad Pros or through the use of an adapter. The specific adapter you need to connect an external hard drive to your iPhone or iPad depends on your specific drive and your specific device.
Tap on the name of the external storage drive to access the contents and use that data from iPhone or iPad.
If things work correctly then you should see the drive show up under locations in the Files application in iOS. Open Files on your iPhone or iPad. My external hard drive using an Apple usb A to usb C adapter doesnt show up on my iPad Pro 11 inch. Older Apple devices used a 30-pin connector but those are mostly gone these days.
