Hoping there is a simple fix to this. My month-old W520 (i7 2720QM, 16GB, Intel 80GB mSATA, 500 GB Seagate installed) sits in a Mini Dock 3 Plus. There have been absolutely no problems booting in or out of the dock.
I recently installed a 2 TB RAID 1 box in the Mini Dock 3 Plus's eSATA port (Raidon 2-disk enclosure, 2x 2 TB Hitachi 5K3000.) It performs well (great speed, very reliable so far.) Everything was fine until I shut down and rebooted--then it hung at the Think screen. Removing the eSATA connection and rebooting led to a normal boot.
I can always take the W520 out of the dock to reboot, but this is a bit of a pain. Does anybody know a way to fix this?
Thanks for any pointers.

Are you running the latest Intel RST? http://www.intel.com/p/en_US/support/highlights/chpsts/imsm

There are similar issues with WD HDDs during boot, look at http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-won-t-boot-when-docked-in-mini-dock/td-p/... Unfortunately, there is no solution at this moment. I'd like to know whether it was properly reported as an issue or at least if there is some progress in resolving it, but it seems the only thing we can do is hope it will be resolved in the next BIOS/UEFI release. By the way, do you use BIOS or UEFI? When I was using BIOS, the issue was exactly the same as you describe. Then I moved to UEFI and now it doesn't freeze on Think screen, but tries to load the OS and during that process it fails and reboots.

Thank you for your thoughts.
@ThosHammer - The RAID provided by the enclosure--it appears to the W520 as a single drive, that is, from the W520's point of view there is no RAID. If I understand correctly, RST is for RAID setups that the W520 would manage.
@Jimm98y - I've got it set to both, with legacy priority.

Updating this older thread. I too cannot get my eSata ports to recognize my RAID1 drive that works fine on my desktop unit.
To be clear: the RAID 1 is totally external, and built into the drive. I only have one SCSI cable from the drive to the W520. It works fine on my Dell XPS desktop with one eSata cable attached.
I am running Windows 7 64
I am running the 5/30/2012 184.108.40.2066 build of the Intel Mobile Express Chipset SATA ACHI Conroller.
I am running the Ricoh PCIe SDXC/MMC Host Controller
Is there some 'on off' to this?
It appears I am running the latest version of the Intel Software.
Do I still need to install the RAID software driver that is mentioned above?

The chipset in the W520 can only enumerate 1 eSata disk drive. This is a restriction of the Intel chipset used for laptop computers. If advanced functionality such as a Port Multiplier is required, a PCI Express add-on card can be used. If it has port multiplier support, an eSATAp port allows a user to connect to a multi-bay NAS machine with multiple hard disks using one eSATA cable.

I understand what you are saying but this doesn't make sense. I had a Samsung laptop (i7) that I got rid of because I hated the screen, and I plugged the exact same drive into it's esata port and it worked fine. I think something is wrong with the esata port on the w520 and am trying to find out if there is a fix. I can't believe that a single esata cable can not work, when this drive works on other esata ports on other computers, but not this one.
No slam on you, I think the answer is not what you assume, is all.

What was the configuration (model, CPU, etc) of the Samsung laptop? The W520 uses the Intel chipset to provide the eSata support. Perhaps the Samsung notebook was using a chipset for the eSata that was not the one native with Sandy Bridge.

Could be. The Samsung is long gone (since December). So what's the story? How do I make this eSata port recognize an eSata drive that works with other eSata ports on my desktop and others? Or should I just sell this W520 and buy a machine that does support eSata as I would expect it to support it? This is unacceptable and is why Apple continues to gain share. My expectations are not being met! This port says esata, and it should support an esata drive.
