I have a problem with eSata on my Lenovo G560 model 0679 running Windows 7 Home Prem. 64 DK (danish language). When connecting and transferring data via an eSata external harddrive (Samsung Story Station Plus HX-DE015EB eSata/usb2), my computer stalls after about 5-10 seconds into the transfer. Nothing further happens. The transfer just stops and stalls the computer.


This only happens when I use the eSata option on the external drive. When using USB2 the transfer is okay at approx. 25 Mb/sec.


Now one would think something is wrong with the eSata hardware-connection on the motherboard or the eSata connector itself. To check this theory I installed Windows XP on the computer, and eSata turns out to work perfect with approx. 70 Mb/sec. throuput. USB2 was around the usual 25 Mb/sec.
I also tried Ubuntu operating system, and eSata was as fast as on Windows XP.


So I believe it's a software/driver problem with Windows 7.



Additional info:
I do not boot from the external drive. It's only for storage.
The external drive is 6 months old and worked flawlessly untill I tried with Windows 7.
I have tried to format the drive with both NTFS and FAT32. Also with Samsungs own formating tool. No difference.
And there is no difference whether I use up all 3 USB-connections on the computer or only use one for eSata.
I have the latest BIOS (29CN31WW v2.08), chipset driver (, Intel Matrix Storage driver (, Intel Management Engine Interface driver ( All for 64-bit OS.
All Windows 7 updates.
I have disabled Windows firewall.

This may be caused by a conflict with Intel Matrix Storage driver.  Uninstalling the Rapid Matrix storage manager may provide a work around.  As overall compatibility can change based on mix of drivers, look for later versions of this driver for a long term solution if the Rapid Matrix Storage Manager use is desired.
