[SOLVED] My 10TB hard drive will not show up in BIOS or DOS and will not Spin up

[OhFor88Smiley]

i have spent hrs with no luck trying to find out why My HGST He10 10TB hdd will not show up in BIOS or DOS i was thinking it was some thing to do with compatibility or some thing!
but then tried it in my nas and works fine so it turns out its not even spinning up in the desk top

i have tried 2 different desktops 3 different PSU's and nas (the NAS is only thing it works fine in)


thanks

i spoke too soon it turns out there is a simple fix.
all you have to do is to use a Molex to SATA, or at your own risk & void warranty is just cut the 3.3v wire on the SATA cable of your PSU and heat shrink it up! see PDF https://www.hgst.com/sites/default/files/resources/HGST-Power-Disable-Pin-TB.pdf

"Q: What exactly is the problem and how does the “Molex to SATA”
connector solve it?

A: Legacy SATA power cables used P3 (Pin 3) to supply 3.3V power to
the HDD. The new feature uses P3 (Pin 3) to perform a hard reset. So if
you plug a new drive into an old system... P3 (Pin 3) may be hard wired to
keep the drive in “Hard Reset” mode, so that the drive will never spin up.
Changing the power connector effectively removes power from P3 (Pin
3), and allows the drive to spin up normally. )"


"(Q: What if I have a legacy system? And I have an HDD that has this
new feature? And the drive doesn’t spin up?

A: You can easily fix the problem by using a “Molex to SATA” power
connector. See figure 1."


i hope this helps others
thanks

You saved me SO much time troubleshooting! Turns out using a SATA power splitter also works, and the 2 drives that wouldn't work before now do without issue! Thank you so much!
