Looks good to me, but microjogs value would be better to know.

hi,
here is the details from DonorDrives.com for matching WD.



Marvell (version 2)

These encompass most newer and modern Western Digital drives.

Use the following criteria to find a donor drive.

Model number: It is ideal to match the whole model number, but if none is available you can try one that matches the entire first part of the model number as well as these three characters in the second part: WD1200BEVT-22A23T0
Heads map: Match the physical heads (PH) map exactly. It is OK if the donor has more heads than the original drive, but all heads before that should match.
DCM: Locate the J or 2 in the DCM. It should be towards the end. Make sure that the J or 2 as well as the preceding character matches on the donor.
Preamplifier: Exact match for both vendor and revision.
Microjogs: Each value should be within 200 of the original drive — the closer the better.
Country of manufacture: Should be the same.
Date of manufacture: Should be within three months — the closer the better.

And inaccurate. WD has more specfic rules depending on the family.
IMO that guide is strict and obsolete.
@OP: The drives should be compatible.
