Mass storage Controller driver not working

Hi, I have sony vaio model # vgncr320e , 2gb ram, 250gb hard drive,windows vista sp1.

I recently installed windows 7 beta 1 by partioning my hard drive. I have alloted 25gb of hard drive space to new windows 7 beta 1 OS.

Problem 1;
In the 'device manager' I see 'Mass Storage Controller' which shows me a yellow sign of exclaimation & the following message pops up when 'right clicked' on 'properties' ;

''The drivers for this device are not installed. (Code 28)
There is no driver selected for the device information set or element.
To find a driver for this device, click Update Driver''

Problem 2;
In the 'device manager' below the 'Mass Storage Controller' name/driver it shows a name/driver called 'Unknown Device' again with yellow sign of exclaimation as mentioned above & When 'right clicked' on its properties I get the same error message as mentioned above.

Self Troubleshooting done so far by me;

1>Update the driver[It couldnt find any device drivers online for both the 2 problems]
2>Uninstall & Reinstall the drivers [Didnt help]
3>Windows updated with optional updates turned on and installed [Didnt help]
4>Reinstall the whole windows 7 beta 1 [Didnt help either]

Conclusion;1>What should i do Now to get these 2 devices working properly without any error messages

2>Where can i find drivers for windows 7 beta to download.

3>Note; When i plug in my usb external hard drive it shows me a message ''Do u want to scan the drive or continue without scanning'' & i tried both the ways/methods but still my files stored in usb external hard drive drive freeze & therefore dont respond immediately when i try to view or open them.

Kindly suggest the way to comeover the problem, thanks

"Where can i find drivers for windows 7 beta to download."
-> For the most part you must download the Windows Vista drivers from the manufacturer and see if they work in cases where Microsoft does not supply or find them automatically. Otherwise you'll have to wait for the manufacturer to release Windows 7 drivers for your hardware.

Try going to Sony and downloading the Vista updates for your model laptop for the memory stick and card reader. That solved the mass storage control message for me.

Sony Vaio TXN29, Vista>Win 7 upgrade. Two yellow flags: Mass Storage, Unknown Device. But I cannot see any loss of functionality. Have you made progress or noticed any deficiency?

I had the same problem. 2 devices not recognized. It was the memory card reader and a proprietary sony parser driver. To find the firmware extension driver on the sony driver download page, you must look under "System Components". Hope I helped. I just solved my issues and figure I'd make it easier for the next person.

1) Sony® Firmware Extension Parser Driver (This is the unknown device)
2) Texas Instruments® Integrated FlashMedia Controller (For me this said mass storage controller)
