2100: Detection error on HDD0 (Main HDD) - problem with motherboard
Lately I have been getting this problem when booting the computer: "2100: Detection error on HDD0 (Main HDD). Press Esc to continue". I used to press Esc and then the computer would boot normally, but the other day when I booted the laptop I just got a black screen and nothing reacting (even if the power button had light, but it would not even switch off). As I did not know what to do, I took the laptop to a technician.
He was trying another hard drive in the laptop to see whether it was a problem with my HDD or with the connector of the motherboard and concluded that the problem was the motherboard and it had to be changed. Basically, the connector is a bit loose, so the HDD moves a bit, what causes the connection problem. As it is quite a lot of money, I decided to take the laptop home and try to figure out a solution.
The solution that I have found is to place two cotton pads from the ones used to remove make up below the HDD, then installing the HDD and place another cotton pad in between the HDD and the sponge that is inside the case. With the added pressure of the pads, the HDD does not move and everything works fine so far. However, I feel that this solution is not the best one. So, I was wondering whether you have better ideas.
Is there any other solution that you can think of so the HDD does not move or to fix the connector without changing the motherboard?
Can you suggest other materials that may be better than a cotton pad?

I see many comments about the HDD error, and I agree with you that it is in many instances being caused by a loose HDD connection. Not sure cotton balls is the answer, but it is definitely a design flaw because the plastic cover for the HDD slot does not hold the HDD firmly in place. Lenovo should provide a replacement cover for the HDD slot with more cushion so the HDD does not come loose.

I had the same problem with my Lenovo E531 laptop.
I didn't have cotton balls so I used 2 cotton swabs - those wooden sticks with balls of cotton on each end. I placed each end resting on opposite sponges. The swabs are longer than the HD width so they rest at an angle to the sides of the HD.
I booted and no longer got the 2100 error. Fantastic! Instead I just got a date/time error. I bypassed the error and I got my Windows 7 desktop back. Of course I reset the date/time.
I'm absolutely thrilled to bits with your cotton under the HD tip!
Thank you very much!

Could someone make a picture of the cotton pad or the sponge solution? I can't really imagine how this works. Wouldn't a cotton pad between the HDD an the mainboard put too much strain on the hard drive when screwing it back onto the motherboard?
