T440p secondary HDD spins down

[cnotteboom]

Hello,

In my T440p, I replaced the HDD with a SSD, and put the HDD in a caddy (bought from hddcaddy.com). My problem is that after booting, right at the Windows login-screen, the HDD spins down ~1 out of 5 times. I can't find it in disk management after that happens, it's like the HDD isn't there. When the HDD does keep spinning after login, it works fine.

What I know is that the cause of the problem isn't the caddy, neither the HDD. HDDcaddy sent me a second caddy, and I tried with different HDD's. So it must be software-related.

I played around in the BIOS, but nothing seemed to work. (BTW, instead of the 'ThinkPad' loading screen, I now have a 'Lenovo' loading screen while booting. What's causing that?)

Does anybody experiences the same problem as me? Because I couldn't find anything alike on the forum. Help is appreciated.

Greetings


ThinkPad T440p 20AN006VMH - Win 8.1 - i7 4700MQ - SSD: 250 GB Samsung 840 EVO (internal) - 500 GB SATA 7200rpm (HDD caddy)

Welcome to the forum.
This is partly due to lack of proper power management in W8.
Lenovo no longer supplies it.
Elsewhere I found a suggestion to install this Intel's RST driver: https://downloadcenter.intel.com/Detail ... 9&lang=eng
See if that helps.
Another option might be if yours is not a genuine Lenovo caddy...

Thanks for the reply! I'm happy to hear it's a W8 bug.. I'll try it today.

The RST driver did not solve my problem.
Other ideas?
