What is the maximum hard drive size?
What's the max hard drive size for this unit? It had a 160G in it and I think I failed. Tried replacing the 160 with a 500G and it isn't seen.
Sounds like the SATA data cable may not be connecting correctly. I would reseat both ends and see if you get the same error. Also try replacing the cable. If these steps fail you may have more serious problems. What was the old hard drive doing?
providing you connected them correctly and did not damage the connector or logic board removing the old drive.
If this answer is acceptable please mark it.
