I just bought a new Plextor M5S 128GB SSD. I removed the old SATA hard drive from my laptop and plugged in the new SSD. I turned on my laptop with a Windows 7 installation disk inserted, booted from the Windows disk, and got the screen where it asks which drive to install Windows onto. It said there were no drives detected.

Then I restarted the computer and went into the BIOS and tried to do a "Hard drive diagnostic test" and it said "Hard drive not exist." The SSD also does not show up in the list of bootable devices.

Next, I put my old hard drive back into my laptop and put the SSD in a USB SATA hard drive enclosure. I plugged the enclosure into a USB port and loaded the BIOS again. I looked at the list of bootable devices and the SSD was listed. Then I loaded Windows. Windows did detect the SSD in the Disk Manager and from there I formatted the SSD. Now I am able to see the SSD listed in My Computer as drive "I".

I tried replacing the hard drive with the SSD again and the BIOS still will not detect it. It only detects it when it is plugged in through the USB enclosure. What do I need to do to get it to detect the SSD normally (plugged into the SATA cable inside the laptop)?

1. I already update the SSD to latest firmware (Problem NOT solve )
2. My BIOS do not have that power saving mode setting
3. Laptop can replace power supply??

I'm the lucky one, get a bad unit SSD, i believe quite rare case right?!...

I just found a friend using Plextor m5s 128GB and I tried to detect it in my Lenovo Y470 BIOS, it works!

So now I just have to wait the seller to switch a new m5s for me...
