It is not something I would recommend to the casual bystander but if you have the skills it can get you over the line - the internals of a hard disk are pretty simple and robust, most failures are the electronics that make it go. -- Brett Lymn -- Sent from my NetBSD device.

That would require a medium having equal or greater data capacity. Taking the electronics board off a working drive to transfer to a dead drive carries the risk of messing up and losing both drives. I don't think I'd be daring enough. The hard-drive manufacturer would surely advise against taking off the electronics board and would point out that it would void the warranty. Tom

ACE Data Recovery https://www.datarecovery.net/ I had a FreeBSD ZFS filesystem that I thoroughly screwed up due to my own negligence. They wanted $1800 to recover it. They had to put another head and actuator in it to get anything at all. They were able to recover a lot of old stuff that I had old backups for, but couldn't recover the stuff from the last year when I had no backup. After a few months of trying they gave up and gave us the disk drive *and money* back. I Highly recommend them. -- Ted Spradley

As for cost I think the attitude of the data recovery places is that they have you by the short and curlies so they can charge what they like, I know that recovery can be complex and challenging but the pricing does seem excessive. If you have the same model drive you could take the electronics board off a working drive and put it on the dead one - I have done that in the past to good effect. -- Brett Lymn -- Sent from my NetBSD device.
