RMA'd 3 TB HDD only shows 746 GB (only seeing one platter)

chesteracorgi · Aug 10, 2013

I RMA'd a 3 TB HGST drive and received a replacement yesterday. Upon installation of the hardware, and booting into Win 8 the Win 8 Disk Management only shows 746 GB (non-initialized unformatted). I also checked this result with Partition Wizard and EaseUS software and got the same result. CrystalDiskInfo correctly IDs the HDD as a 3 TB model, My analysis points to the disk only reading one of the platters,

Does anyone have any experience with this? My analysis points to a defective replacement and another RMA.

That is not a defective drive. There are a number of items that need to implemented in a PC system for 3TB drives to work.

Hi

Does bios correctly identify.make, Model , size of drive
If not windows will have a problem

You did not specify motherboard model

Maybe a bios upgrade will help
Or connecting to different Sata controler chip if available

Regards

Calvin, I am using Win 8 which shouldn't have any problems with a 3 TB drive. The limitations in Win 7 were supposed to be corrected in Win 8.

The drive is correctly ID'd in BIOS and by CrystalDiskInfo. I am using the Marvell SATA controller on an ASRock Z77 Extreme 6 mobo: the Intel SATA controller channels are occupied by a RAIDED Samsung 840 Pro 256 pair of SSD's.

The HDD's predecessor (same model) was initiated in Win 7 Ultimate and transferred to the Win 8 system and was fine until it took a dump a couple of months ago.

The specifications for the Z77 Extreme6 do not list any Marvell Storage Controller. The board has 2 x SATA3 6.0 Gb/s connectors by ASMedia ASM1061. You need to format the 3TB drive with GPT format.

You're right, it is an ASM controller, not Marvell (that was on the P67 Estrmee 6).

Calvin7 :

Calvin, the problem is that even in GPT format the disk only shows the 746 GB. I cannot format it for 3 TB because it only shows 746 GB.

It looks like it is RMA time again.

Go to Control Panel, Administrative Tools, Computer Management. Choose Disk Management on the left and you should see in the lower portion of the screen a list of your installed drives. The larger drive should appear in the list with a capacity displaying on the left.

Now, right click on the partition on the right, right click the partition (if there is one on the drive already) and click "Delete Volume".

Now, right click on the name on the left "Disk #" and choose "Convert to GPT Disk". Now this should allow you to right click on the unformatted space on the right and to create a new partition which can hold the full available capacity of your drive.

Calvin,

You son't seem to get it: there is no volume to delete. The disk is already in GPT and it still shows only 746 GB. The drive is defective and only sees one of the three physical platters.
