I have the exact same issue but from doing a system migration, when I press on "online" and go to do the system migration again, i get the exact same error.

Brilliant. I was scratching my head thinking I had a dead Hard drive. Thank you so much.

Just had this happen for the first time in about 100 external drives ;) Didnt understand the need for all the cmd/diskpart explaining though, only made it more confusing. Would only need to know to put as online in Diskmanagement and then you are good to go :)

Thank you! Nice video

Mine said the parameter is incorrect

thank you! great help.

case: cloned my hdd to my new ssd. then placed my hdd to an enclosure to make it as an external hdd. formatted external hdd using a different pc, then when I checked it in my laptop, it says offline because it has signature collision.

followed this advise, and it greatly helped! thank you

Thankyou!
