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 2
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
