hey guys, I Have 640 GB Sata Hard Disk, I want To use It As External Hard Disk Connected To USB With Adapter. But I Have Some Problems, When I Connected It To USB Sometimes It Works Fine, and Sometimes It Say Found New Hardware (r6e4326gwedej38rfwe) [any corrupt name] and I Can't Access The Hard, Sometimes It works Fine But After Awhile I Can't Access It [It Says no Devise in Drive ( )] I Try: - Connect The Hard Disk To another Computer - Connect It To Windows Vista (I'm Using XP) - Use another Hard Disk (320 GB Sata) - Use another Adapter To Connect To USB All of This, and Still The Same Problem. But With 160 GB DATA There is no Problem *Any One Has Any other Solution? and Thanks To All of You...
