I think I have posted this in the right section. If not, bear with me.

 

Okay, so I've got this IBM Lenovo ThinkPad X201i which arrived with a noisy as heck 120GB hard drive and 4GB of RAM, it also runs a Core i3 1st gen running at 2.13GHz (model number escapes me currently) and it ran fine... but of course, me being - well me. I just HAD to upgrade it a wee bit because I should know fine well to leave stuff alone but I don't. So anyway, before I get off topic too much, it doesn't recognise the 480GB SATAIII Kingston SSD I slapped into it but it recognises it if it is in a USB caddy.

 

I've tried to format it using that computer and another one and it formats fine, but the Thinkpad's on-board BIOS doesn't agree with it as it doesn't see it at all. I have absolutely no idea what to do as swearing at it hasn't gotten me very far! 

Maybe check if a bios update can help?

I had a similar problem when I upgraded our Samsung laptop to SSD. I bought a Samsung 500Gb SSD, cloned the existing 500Gb hard disk to it using an external caddy but when I replaced the HDD with the SSD the laptop would not recognise it. After many email conversations with Samsung and them replacing the SSD it still would not work. I then bought a Crucial 500Gb SSD, cloned the laptops HDD, and when fitted to the laptop it worked straight away. Why the Samsung SSD would not work in a Samsung laptop I do not know. The Samsung SSD is now fitted to my Windows 7 desktop and is working perfectly.

Sorry! I forgot to mention that I've updated it to the newest BIOS I could get on Lenovo's website. It was a long day yesterday 

@Liger1956 - I'll take the Crucial BX out of my desktop (which is out of action currently) and give it a shot in the Lenovo. Thanks!

Thought I'd update this...

Rookie error: make sure the SSD (a slimmer drive) isn't narrowly missing the SATA connector.
