It seems that Vista will not recognize my external hard drive, a Lacie Bigdisk.
It says that I'm missing a driver, but the thing is, it never required a driver in Windows 2000, or XP.

My question is, Is it possible to use a generic driver for this, or do I just have to wait for Lacie to create a driver for it?

I'm having the same problem. I've been using my 500GB external with no problems, but now it say it can't find the driver to install the HD. Aarghh!!!

says

My Big Disk will not mount or is not detected. The System Profiler on my Mac or Device Manager on Windows lists it as unknown with the name TUSB6250 Boot Device.

Please try the following:

# Disconnect all cables connected to the drive.
# Connect the power cable to the drive.
# Connect the USB-cable. First to the drive. Then to the computer.

If the drive is detected correctly the problem was probably caused by improper shutdown or un-mount (unplugging the cable without dismounting first, etc.). When this has happened, the USB-interface needs to reset itself properly. After this, reconnection should be no problem.

I was having that problem for 2 weeks now. Your suggestion worked great. Thanks

I had the same problem. Thank God for people like you.

Same problem here in Kazkahstan. Your solution worked like a charm.
Thanks dude!

Thank god for clever people and internet forums!

The above solution worked perfectly!!!!

THANK YOU. YOU ROCK

It worked like a champ.... Thank you so much....

Well, I'll be darned. This worked. Make sure you don't hit the power button on the front of the drive. Just let it power on automatically when you connect the USB cable to the computer.

Thanks to the person that gave the cable connection sequence!
