Connecting Hard disk of different laptop

[hdani]

Hello guys!
I am trying to connect Compaq Laptop Hard Disk SATA to Dell Inspiron for Compaq's data recovery purpose through data cable/ USB port. But, the Dell is not detecting the Hard Disk. Can someone direct me the steps to detect it? Otherwise what can be the fault in the Hard disk?

Maybe the drive is locked with ATA password ?

Did you old laptop used BIOS password ?

Also can you test the drive directly on another system by SATA ?

What is the full model of the drive ? Can you ear it spinning at all when you connect it using the adaptor ?

No, there was no password.
I don't know whether Dell inspiron is SATA or Ide .I guess it is not SATA. No there is no spinnning . Model name is :
WD1200BEVS.

Check in the laptop bios to see if the drive is detected.
