I have a Lenovo ThinkPad R500. I took out the original HDD and installed an SSD drive.
It ran well for a month and then suddenly froze while restarting.
The SSD was formatted and Windows 7 re-installed.
Now the computer only displays an error telling me to "check cable". It starts up and runs on the original disk and I can connect the SSD through the USB port and read everything that is on it.
Does anyone know this problem or better, the solution to it?
