part number 539613-001

[Mike Texter]

I am physically holding in my hand an HP hard drive, p/n on both the handle and the disk itself is 539613-001. It is a 2.5" SAS disk, and appears to be the same as a 512744-001, but it isn't anywhere on partsurfer nor the HP disk drive matrix. 

Where can I find info pertaining to this disk?  We ordered the part number 512744-001 from an HP var, but received these instead and can find no info on them.  They'd be fine for our purposes since the specs all match, but we've had issues in the past with customers balking at the exact part number (they are looking for 512744-001) not being physically on the drive/drive carrier.

Thanks for any assistance!
