Terrible records, scratch easily, sometimes same record, same preamp, not compatible or other times clean surface, you plug in a donor head, after 20 minutes it breaks, totally useless.

If I read your comment correctly, I agree that the Rosewood platters are pure garbage and head swapping is very costly due to the low odds of compatability and high odds of failing after a few minutes.

excatly, Last week, I had a case of a customer with glued heads, and from the label it was identical to another customer who had good heads but firmware problems, I go to unglue the heads, but I don't turn on the patient, I directly insert the donor heads, the donor turns on, reads modules, sectors, everything, I go to DE.... and puff, disk KO

I have Rosewood st1000lm035 1rk172-568 with "alternative" preamp. Others have suggested that if a patient pcb is mounted on a donor drive and it spins up and gives terminal respnse that it will be a suitable donor. My donor is "default" but it spins up the patient drive and gives terminal output suggesting it would be a suitable donor. Can "default" heads ever be used to replace "alternative" heads? If not, how would one go about finding "alternatve" heads...just blindly keep buying donors till one shows up? And finally is the -568 in the part number important or will other 1rk172-??? part numbers work?

I finid that if the drive is relatively healthy and doesn't need to write, almost any set of donor heads will work. However, in other cases, the only luck I have is to match the exact label on the heads themselves.
