2100: Detection error on HDD0 (Main HDD) - problem with motherboard

Hi everyone,

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?

Cheers!

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!

The battery solution works for me. Thanks a lot love you!

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?

Answer is very simple. Remove the battery and put it back again. It works. Same thing happened with me. I could fix it same way.

Hey, had the same issue. Pulled the battery out. It worked. Thanks

It didn’t work for me. Could the battery by itself be the issue? My battery doesn’t lock in place anymore.

yes , it works for me too, thank you a lot!

If you can, you can re-flow or change that connector,

Otherwise quick solution is to buy a dvd to hdd or dvd to ssd caddy and throw in the ssd or hdd. You can buy another usb adaptor or enclosure for that dvd drive.

Thanks for your answer!

I did't know I could change the connector without changing the motherboard? How can I do that?

さんによる

First you need a replacement connector part . You need to buy a heat gun to do it, or you can do it with flux and soldering iron,but might be more difficult. You need small precise tools. You need to put a lot of attention to do it. If you plan to heat more important parts you must buy a good head-gun , but if you just get one for the connector, you can buy cheaper one. You need to buy one with variable temperature. Its very important, because otherwise you will melts the logicboard. There is a lot of professionals that can do it , that may not charge you a lot for it.

The cheaper solution is the dvd caddy...

I simply solved the problem by changing Legacy First mode to UEFI First mode in the Startup options of the Bios menu

A cut off a bit of a dish washing sponge. Don't what those are really called, but I think you know what I mean.

One piece behind the HDD and one between the HDD and the lid. Works perfectly!

I used legos for the same issue! Mine was an issue where the SSD was smaller than a traditional hard drive.

When I opened the back panel and visually inspected the hard drive, I noticed the sata connector was slightly out on one side and all the way in on the other side. I’m talking maybe .5mm to 1.5mm. I took out the hard drive and found that a tiny little corner for the plastic sata housing on the hard drive had bent in. This little plastic was not allowing the drive to go all the way in. I used a precision screw driver with a small 1.3mm flat head bit to get the plastic piece out. Plugged it all back in and it worked! So it was physical hard drive connection issue with my laptop.

The piece probably bent in when I put the hard drive in yesterday but it worked all day yesterday and when I restarted this morning it no longer booted into Windows. Also, the sata connector on the motherboard had no play and didn’t wiggle at all, so that was in great shape.
