Disk utility won't format usb SSD
I have an internal ssd Crucial that I used in my iMac and that for some time I used as an external disk connected with a Usb 3 Sabrent adapter. The disc has always worked both inside and out but when I tried to connect it to an iPad Air 3 through the Lightning usb-3 adapter, the disc, after appearing for a moment on iPad files, has disappeared. Since then I can no longer mount it on the Finder of any Mac. Disk utility can still see it but if I try to format it the process crashes while creating the partition map, it seems impossible to activate it. I tried also with Disk Warrior being able to recover some data, but the disk cannot be formatted anyway ("TM" cannot be activated. Com.apple.DiskManagement.disenter error 49153). do you have any ideas?
