grady :
No, it doesn't. It doesn't have any partitions or drive letter assigned to it at all.
The latter part of your answer suggest you do not understand the question, and are NOT IN BIOS looking for the drive.
We are providing INTERNAL steps, this will NOT work with a drive connected via USB:
Please confirm you :
1) Turn on PC
2) IMMEDIATE when you see the makers logo / text (i.e. SAMSUNG, DELL, etc. NOT MICROSOFT) hit the F2, F3 or whatever key it says 'to access BIOS.
3) If you SEE the WINDOWS logo, go back to STEP 1 and try again.
4) Enter the TEXT BASED BIOS, look for the EVO listed, if it is not listed, shut down the computer, open computer and reseat the cables to the EVO and repeat from step 1
5) IF EVO is still not listed, try connecting EVO to another computer to see if you can see it.
6) If still not visible via BIOS on two machines most likely the drive is toast, Last test would be to use a SATA to USB cable and plug the drive into the USB port and see if it display via BIOS then (it will list IF it is working). If still not working see if that one is still under warranty and go to Samsung to follow thier process for a RMA request.
