You may wish to save the data from the drive onto another disk (borrowed?), and then format to NTFS, and just have it as a normal Windows-compatible USB HDD. Note that the trial version of Paragon ExtFS only has a 10-day trial period, after which it degrades the data transfer rate.
I haven’t used ExtFS, so I don’t know how well it integrates into Windows; i.e. does it work like a device driver, allowing the disk to appear transparently as Windows disk, or whether it needs ExtFS to run as an application. My original suggestion of Paragon was based on the concept of temporary use for data recovery, not regular use under Windows.
Or sell it on eBay. With a note saying it’s not working, of course. I’ve been thinking of looking out for MyCloud enclosures on eBay, with a view to making a ‘just to play with’ box. One with a broken network port, I’d hope to be able to get working again (possibly rather optimistically…).
The other possibility is to recover the data, and then try to resurrect the device using one of the ‘unbricking’ procedures to restore the operating system and file system; it may not be a hardware fault.
