Win 7 randomly loses ReadyBoost key drive

I have just updated Vista home Premium to Win7. Most things are working fine, but Win 7 keeps losing my 8GB USB drive that I am using for ReadyBoost. At random (but most times) after a re-boot the drive shows up, but with no file contents shown. The legend in properties says that it cannot be used for ReadyBoost as the drive is not USB 2.0. Right Click and "eject", remove the drive, stick it back in again and readyboost activates and the 8Gb file appears. Any ideas why Win7 might be "losing" the drive? It was fine (albeit limited to 4GB) under Vista. Sounds to me like a driver problem, but nothing shows up in the properties or elsewhere as faulty. I have updated everything that Windows Update can find. Any ideas, please?

OK, I'll have a look into that. I don't think I'll get far as I can't find any drivers specific to Windows 7 on Intel's site for the P35 chipset, and their automatic driver detector doesn't support Windows 7 yet. How on earth a (the?) major chipset manufacturer is so far behind (on their website at least) I can't understand. However, I'll keep trying.

Your machine with 3GB would gain little to no advantage using Readyboost so I wouldn't worry so much. Biggest improvement is applicable to 1 GB machines or less.

That said, you could try attaching the device to a different port. Try one on an add-on card you may have if its currently attached to motherboard.

It was just an experiment to see if there was any advantage, so you're quite correct in that it is far from essential.I've tried a couple of ports on the card, but not the other way round - the motherboard ports are on the front of the machine and not convenient for a permanent fixture, so to speak. However, I'll try using my four port extension to see if that makes a difference.

I have exactly the same problem here. Nothing to add, really, it's exactly as described.

The other tip I got - disabling the USB boot facility in the BIOS - didn't help either, it wasn't enabled in the first place, so the problem is still there. I still haven't found a chipset update, so I still have the same problem.

Still the same problem here too.

Read the thread again...here's something to Google and consider.

"upper filters"

Compare your machine to known good one, in the registries. Make adjustments if necessary. Set a system restore point first.
