Hi and Welcome!
replacing a notebook drive isn’t easy at all.
There are basically two issues that might prevent proper operation:
[B]- drive configuration: [/B]
Notebook drives have their master/slave settings buried in the firmware, so you have to find out the setting of your original drive. Changing these settings with a new drive can be a pain
[B]- mechanical restrictions:[/B]
Many notebook drives have a custom faceplate, some others have standard plates. Custom faceplates can often be removed and installed at another drive.
In addition, Panasonic/Matsushita drives aren’t known to be very reliable. I personally would suggest some NEC/Optiarc or Lite-On, since there is at least some support and tools available. For Panasonic: nada.
