I have a portable hard drive, it worked then I switched it on and a blue light comes on as normal but next to it a red one also appears. When its connected in the computer seems to know something is connected with the noise but the hard drive doesnt show up in the my computer bit any more. However it shows up in the safely remove hardware bit as USB Mass Hardware Device.
The Hardrive is a:
Western Digital Scorpio 160.0gb
And the other information which you might want to know, means nothing to me but:
WD1600B EVE - 00UYT0
Drive Parameters: LBA 312581808
Enhanced IDE Hard Drive
Hope any of that stuff helps. Thanks
