WD60EZRZ: Unable to format its full capacity

[oxy]

Hello guys, good day.
I'm using a WD60EZRZ as the 2nd HDD attached with Thinkpad X201 Ultrabase thru SATA direct connection cable.
Primary SATA disk is a 256GB SSD for windows.
For these three years, it'is recognized as proper capacity 6 TBytes.

Sevaral days ago, just after power cycle, Windows could not start normally, then RnR 4.0 (Resque and Recovery) automaticall ran about three hours.
After succesfull finish of RnR process, the disk (WD60EZRZ) seems 1.493 TB(TiB) not 6 TB on DiskManagement of Windows.

So, I cleared all partitions, then reformat the disk as GPT single partition. But the capacity is still 1.493 TB.

Next, I did low level formatting whole the disk using HDDLLF4.40. It taked about one hour. Just after successful finish, the capacity is still 1.493 TB(TiB). At this moment, I believe that there are no MBRs and no GPTs.

Misteriously, Devicedetails tab of HDDLLF reports: "Full device capacity: 6,001,175,126,016 bytes"

Are there any solution to fix device capacty ?

I appreciate any advices.
Thank you.

Your system is affected by a 32-bit LBA limitation. This could be a BIOS issue (did you select RAID mode for the SATA controller?) or a SATA driver issue (Intel RST?).

6001.1 GB - 4TiB = 1603 GB

Dear fzabkar,
Thank you for appropriate advice!
Until sevaral days ago, I used this disk in an external USB enclosure.

Again I connected the disk to USB3.0 external enclosure, instead of SATA direct connection.
Then, the disk could be formatted as full capacity successfull by HDDLLF.
Windows disk manager recognized proper capacity of the disk.

Best regards,
oxy
