I have just got a Drivestation HD-LXU3 3TB today
and have noticed a problem with it
There seems to be a bug in your sata to usb controller firmware on the Drivestation HD-LXU3
I have tested this around 20 times
A firmware update to fix this would be appreciated..
Hardware Details
Windows 8.1 Pro (Stock USB Mass Storage Drivers)
HP Microserver Gen8 (Ivy Bridge)
16 GB Ram
Renesas Electronics USB 3.0 Host Controller (µPD720202) (Driver 3.0.23.0) (Firmware Version: 2024)

This needs passing on to your chipset vendor to verify and fix (if they havnt fixed it already with an updated firmware)
Turning on spindown with HD-LXU3 Enable, Disable
results in the same problem
I have found a quirky way of getting everything going as it should
uninstall the renesas usb drivers
so you are using the microsoft default renasas usb drivers
reboot
enable spindown
enable better performance
results in a max of 102 meg a second over usb so the same problem is exibited (the microsoft usb drivers are slightly slower..)
install the renasas drivers again (RENESAS-USB3-Host-Driver-30230-setup.exe)
spindown carries over
better performance carries over
speed isnt crippled
Side note this clearly is a problem at buffalo's end that needs fixing asap
my Seagate Backup + drive doesnt exibit this problem
and i shouldnt have to do all this just to get spindown and write caching going without a huge performance drop

Also your crappy spindown tool
is just hacking something at the os level to enable spindown on the drive
Why havnt we got a hardware level tool to set spindown on the sata to usb bridge
like every other usb driver manufacturer supplies
so it will carry over to different pc's etc..
i wouldnt be supprised if this is the cause of the problem your dodgy hack on the os to spindown a usb drive
