I have iflash hd and it shows device storage is offline. How do i get device storage online?

Hey there, blackhawkgcw,

Thanks for visiting the Apple Support Communities. If we understand, you have an external storage device you're trying to use with your iPad, but keep receiving an error that it is offline. We are happy to help!

First, check with your device manufacturer to ensure it is compatible with your iPad model and currently installed iPadOS version. Then, review the information in the Apple Support article Connect external storage devices to iPad - Apple Support to make sure you are set up correctly. Once you have confirmed the previous, try restarting your iPad: Restart your iPad - Apple Support

If the issue persists after that, please get in touch with Apple Support directly, which you can do here: Get Support.

Have a wonderful day!
