Apple infinite load. I/O error and even a new HD My mac mini from the 2011 refused to boot. Apple logo and loading image forever..

I tried cmd+s: Went through all the steps from the applejack, tried fsck -fy, all semmed pok,

Tried cmd+v: It wouldn't fully load, got the error Disk02 I/O error (it was the original 1TB disk with two partitions),

So I thought the HD must be done, so I bought one Samsung SSD HD 120GB Sata 3,

Same result.

Thing is that I tried with both drives to install again the mac os x vía USB (I don't have a CD drive) and in both cases I came up with the tipical 'you must reboot your computer' error scereen.

So With the new HD replacing I did same steps, cmd+s and cmd+v provided same results....

Any thoughts?
First I would try doing the NVRAM reset by restarting and holding down Command-Option-P-R until you hear the startup sound a second time. Then I would try an SMC reset. Mavericks and Mountain Lion can be pretty finicky and even strange when new hardware is installed. I've had to reset the SMC on my system with Mavericks 3 times since I started using Mavericks. In my case, it's Mavericks, not the hardware. It's buggy.

The I/O error typically is either a bad drive or cable, so you probably did have a real hardware problem at some point. I'd be inclined to recommend Scannerz (http://scsc-online.com/Scannerz.html) to test it, but you need a working system to use it, and if you can't even get yours to boot, that obviously won't help.

Does the Mac Mini even have a SATA cable to the HD, or is it a connector that sits on the logic board with the HD plugging directly into it?
