I have an 80GB IDE Hitachi HD which was formatted NTFS on my computer running Win 7 Ultimate. My problem is that when connected to my computer via external Sharkoon Drive link USB adapter, it is not shown in Windows Explorer but is shown in Device Manager as USB Device and in Computer Management it is shown as ‘Disk 1 – Not initialized’ and when clicking on to initialize, an error shows as ‘This device not ready’. Same occurred on another PC running Vista Ultimate. Strangely, when connected to IDE inside PC it works perfectly. Can anyone help please?
