I used a WD20EARS-0MVWB0 to smart hot swap a similar drive (it worked, that's done). The problem I'm having and often have after smart hotswap (moving all patient tracks to donor) is restoring the drive back to it's original state.

I always just try writing all the service tracks back to the drive, but it often either doesn't finish or gets too slow to finish, like writing 1 track every 10 hours.

With this current drive, I tried writing it's original backup tracks back. It took about 20 hours to move them all back (at first was fast, then got slower towards the end). Now the drive comes ready with no ID and no SA copy available:

Trying to write tracks says I need a Loader. I've tried every loader in DB (including the original loader for this drive and the patient drive), but all give some error and do not work.

What else can I try?

More importantly, can some expert out there provide the (or "their") proper procedure to restore donor tracks back to donor so its working again after smart hotswap?

Thanks!
