Hi Seena,

Could you tell me model of your hard drive? It seems to me that it is an internal drive. How do you connect it externally, with a SATA to USB cable or with some enclosure? Does the drive work properly when connected with a SATA connector? I recommend you to try the HDD on another PC and see if there will be difference. If formatting the drive is an option, try using the Diskpart command from the Command Prompt. You can use it to clean partitions and assign a drive letter. I leave you some details below. To confirm the drive's condition, I recommend you to use Data Lifeguard Diagnostic, the WD diagnostics tool. I leave you a download link below.

Hope this helps

Sir, it is WD Model MDL: WD20EVDS-63T3BD, a 2tb desktop hard disc. It was previously used by Dell Desk top system running Windows 7. I got it removed and used as external hard drive for my laptop with the support of external USB enclosure. Windows XP did not recognise it at all. Even in Windows 7, only in Disk Management it appears as a oem disk without any space. Even I tried diskpart, but did not succeed. It says, it has not partitions at all. I also could not format it.

Some enclosures or adapters do no provide enough energy to run properly a 3.5'' hard drive. If your HDD works fine when connected with SATA cable, then the issue comes from the cable. I strongly recommend you to check the drive on another PC, as an internal drive. What options do you have when you right click on the drive in Disk Management?

Hello seena,
Did you check how you connect your desktop HDD to laptop?...The Desktop HDD needs suitable power if not it will not recognize in laptop.. did you try this HDD with any other computer and tell whether it is working?
