Take a moment to look at the photos and description of this "relabeled / reconfigured" drive. The OS reads the part number of the drive as MZWLL3T2HAJQ which is supposed to be a 3.2TB drive but it has been reconfigured by Samsung to be a 3.84TB drive. The OS reads the capacity as a 3.84TB drive and the drive have been relabeled to be a PM1723b 3.8TB drive and they function as a 3.84TB drive. These were RMA replacements and this was done by Samsung at the time due to supply issues and not a 3rd party hack. They are replacement drives and used as hot spares so they have relatively low hours and and almost writes to them. 100% heath.
