OK so I buy this new 300 GB extrnal and connect it and download a free trial version of back up software and it performs as expected but it adds emtpy folder to my C:. Not knowing, I uninstalled the back up software and next thing you know the drive is no longer working. However it started working and I checked the drive and found the back up and then it stopped working again. The tech at WD said that I may need to up date the USB drivers ( how)? The USB says the device is working fine but the properties shows no free and no used space and file system is "RAW". I tried to update the driver and still nothing. Any ideas would be great. From WD TECH: Western Digital does not provide computer or operating system drivers for external or internal hard drives. Western Digital pre-formats your drive in a FAT32 File System. This File System is recognized by most computer operating systems, but in some cases, you need to make sure you have the latest BIOS updates and drivers installed for your system or motherboard, and any Windows updates and service packs. Windows ME, XP, 2000, and Vista have full driver support for external USB hard drives. However, if you are seeing an unknown driver listed in device manager under other devices or USB mass storage controller drivers, you would need to update or reinstall your USB port driver supplied by your system or motherboard manufacture before the drive will be recognized. I would also make sure the power adapter is connected directly to your wall socket to see if this helps.
