HDD not recognized with new HD cable?

[-mattias-]

Hello,

I have a MBP 13" 2010 where the old HDD was somewhat damaged. It could only boot up in safe mode and was very slow then. I bought a new HDD and HD cable.

Installed the new HD cable and HDD, but when I booted up from Disk Utility it couldn't detect any HDD. Tried changing the HDD to the old HDD, but now it couldn't find the old HDD either and it couldn't even boot up in safe mode.

So I don't really know what the problem could be?

• Wrong cable
• Broken cable
• Not installed properly.

Can't think of any other options.

Some of the older units don't recognize newer hard drives without letting the NVRAM learn about them. Try this:

to reset the NVRAM, which contains the startup disk ID.

Please let us know if this works too for future reference to everyone else.
