X220, UltraBase Series 3 and DVD Multi IV, series problem

[baoshi]

Hi,

I have these combination:

ThinkPad X220, 4286-CTO i7/USB3.0 model
ThinkPad UltraBase Series 3 P/N: 0A33932
Serial UltraBay Slim DVD MULTI IV P/N: 45N7451 (HL-GU10N)

I have encountered this problem:
When the DVD writer is in the Ultrabay and I init a system undock (Choose Eject Docking Station from system tray), the system freeze. Same when I press the button at left side of Ultrabase.
When DVD writer is in the Ultrabay and I slide the switch near Ultrabay, the system freezes.
If I turn on the "Power Off CDROM device when idle" in power management, the system freezes after some idle time.

Everything works fine when the Ultrabay is empty.

Is seems that everything points to the DVD writer, however the same DVD works well in X201 Ultrabase.

Can anybody help me?

Thanks

Solved. Replace ms sata driver with intel's

I am having this same problem. I installed the latest chipset drivers from Intel (http://downloadcenter.intel.com/Detail_ ... ldID=20019), but that did not fix the problem. This appeared to be the relevant driver based on what Device Manager is telling me, and I couldn't find any drivers specifically for Intel SATA that looked appropriate.

Which Intel SATA driver are you referring to? Can you provide a link?

Thanks!

I contacted baoshi via private message (he is no longer monitoring this thread).

In case anyone else experiencing this problem finds this thread, the driver you need is the one for Intel® Rapid Storage Technology. After installation, you should find only one item in Device Manager listed under IDE ATA/ATAPI Controllers, named Intel Mobile Express Chipset SATA AHCI Controller.

The Driver Details for this device should show that it uses only iaStor.sys.

As of this posting, the latest driver can be obtained here:
