My wife has a 2TB external harddrive by Mediamax. It stopped working so I took it out of the enclosure and examined it and it appeared that the USB cable had failed as Windows 7 would not believe me anything was attached, but the hard drive had power and was obviously spinning.
I then bought off ebay this cable:
USB to SATA 15+7 22 Pin Transfer Cable Connector Conversion 2.5" HDD Laptop PC | eBay
USB to SATA 15+7 22 Pin Transfer Cable Connector Conversion 2.5" HDD Laptop PC
In the hopes that I could then attach this to the hard drive and read the data. Now windows 7 drive manager says disk 1 is unknown and not initialised. When I tried to initialise it (I realise I don't want to) it says the drive is not ready. The Hard Drive is not spinning audibly any more. I believe it is possible that the drive is not getting enough power even though I have plugged in both USB cables of the cable shown.
I hope this is enough info.
Please help me as my wife would be ecstatic to have it working again.
