Is it recognized in BIOS? what format is it? Does it have a drive letter?

Hi Ken,

Thanks for your response.

The drive is about a year old and has about 200 GB of data in it and has always worked on laptops running Windows 7 / Windows XP. Stopped working after I connected it to a Mac.

On the Win 7 laptop, the drive is not recognized.

On the XP laptop, the "found new hardware wizard" popped up and tried locating a driver. The final message was
"The hardware was not installed because the wizard cannot find the necessary software"

I also tried replacing the cable.

It is not recognized in Bios. The HDD format is NTFS and the drive letter does not show up.

Regards,
Sunder
