the point now is that you wont be able to show proof of purchasing the drive as a bare drive.
you will find all this out when you try to exercise the bare drive warranty.
Actually the HGST warranty statement (found here [hgst.com]
) clearly states:
"A valid proof of purchase may be required to prove eligibility. If you do not have a valid proof of purchase, the limited warranty period will be measured from the date of sale from HGST to the authorized distributor.
So yes, you can file a warranty claim without a proof of purchase - your purchase date will just be backdated to the original shipping date (aka the date that it shows when you check the warranty in the first place).
