Error 2101 Detection error on HDD2 (mini sata) in T430s

2012-09-22, 5:22 AM

I got my 430s, and it's with a 16Gb mSATA SSD cache inside.

Now everytime when I open my PC, it shows Error 2101 Detection error on HDD2 (mini sata) and I need to press ESC to continue.

Is there any software or driver's problem, or it just phsically got wrong?

Any techician could help to solve, or I have to do it my own?

Solved! See the solution

Have you ensured you are running the latest BIOS?  What version BIOS do you currently have?

 

After pressing escape does the computer boot normally?

The Error 2101: Detection error on HDDx miniSata is a BIOS error. This has nothing to do with the operating system you have installed or any drivers. During the POST, the system does not see the miniSata drive.

 

I (like some others) received my new T530 yesterday, setup it all up and then a few hours later received this error.

 

The solution is simple. You must open up your ThinkPad. Remove the two keyboard screws and remove the keyboard and RE-SEAT the miniSata drive. There is 1 screw holding the board down. Remove it, re-insert it in. Screw everything back up and voila, no more issue. Go to the Lenovo / ThinkPad Guides and Manuals page for your device (http://support.lenovo.com/en_US/guides-and-manuals/default.page?) and download the Hardware Maintenance Manual for your ThinkPad. There are clear instructions (for those less inclined) on how to remove the keyboard. You do NOT need to disconnect the ribbon cable. Simple / carefully slide the keyboard forward and the miniSata drive will be visible and accessible.

 

You can also use the ExpressCache program to get stats on the miniSata drive and see how it is working. Open a Command Prompt (in Administrator Mode) and issue the command:

 

eccmd -info   -   Display ExpressCache activity informatio

 

eccmd -?   -  Will show you all options

 

eccmd -format   - Will reformat and clear the cache drive.

 

Hopefully, this will help out those out there with this issue. Just remember, if the BIOS doesn't see the device, it is not a driver problem !

As I've just posted on another thread, I have the exact same issue with a W520 and Crucial mSATA SSD. It's happened twice now in a short period of time (a few days). Leaving battery out for a while has cured it so far, but this is no good and I very much doubt the problem is a poorly seated card. It is held firmly in place with a screw. BTW, "eccmd is not a recognized command". Where do I get that programme?

Download ExpressCache from the following link that corresponds to the Windows 7 installation (32bit or 64bit):    

Also, see this post for more info:

 

http://support.lenovo.com/en_US/downloads/detail.page?DocID=HT074404

 

ExpressCache is the software which manages the 16 GB mSATA drive as an additional cache for rapid loading of programs. It is different than RapidBoot and RapidBoot Shield. It should be preinstalled on any ThinkPad system which has the 16 GB mSATA drive...

This helped, thanks a lot for the info. In fact I suspected that I've received a T530 with some hardware defect since day one when my browsers run so slow almost like they crawling with some computer running 512mb of ram. Then today the hardware error message pops up when i restarted. And in the command prompt the 'eccmd -info' is returning HDD2 error. Then I found this thread.

After removing the keyboard, the mSata card seems sitting intact and solidly attached to its inserting port, but I took it out and re-inserted it anyway. My T530 works like a charm then, just as a laptop costing more than $1500 should.

I can't seem to figure out why Lenovo delivered a laptop with a badly seated mSata, don't they have the basic hardware QA to ensure all components are working fine? Or could this contribute to the physical vibration the laptop experienced during packing and shipping?

Well, who really knows why a number of systems are having this problem. But, for me the key is that the problem is resolved in 5 min by yourself !  Glad to know that it helped you solve the issue.

 

Yupp, my new T530 is humming along nicely. A nice step up from the T510...

Tried re-seating the card and rebooted.  The error message went way just once and the computer acted squirrely.  Re-booted and got the message again.  So, I'm putting in a service request to probably get a replacement.  The computer is less than a month old.  I shouldn't be getting these errors!

This problem arose on my T430s Win7 x64 HE (stock) after the massive (>400MB) automatic Microsoft Update overnight. (I had last updated 10 days before.)

The problem was fixed with the Lenovo System Update, that also updated my BIOS among other things. (My last Lenovo update was no more than 45 days ago.)

If the screw that holds it in place was installed, it cannot be mis=installed.  It sounds to me like a hardware problem

I just got this same error after a blue screen of dreath. Removing and reaseating the msata drive, which is my c drive, has no Effect. Nor does leaving out the batery. Laptop is effectively bricked.

Removing and reseating the SSD card may work sometimes, but you can try this before :
- remove the battery ;
- the battery being removed, press ten times the power button during one second each time ;
- press the power button again during thirty seconds ;
- connect the battery, and maybe your laptop will boot then normally.

This tip worked for me (on a X220, but the "error" is the same), and it is pretty easier than removing the keyboard, and so on...
This works probably because you need draining the whole electric power remaining in he machine's condensers.

 

This tip will not avoid that "error" to occur, but it allows the computer to start again in less than two minutes.

 

Let us hope mSata SSDs are going to be more compatible with the BIOS of the Lenovo laptops in the future...

Re: Error 2101 Detection error on HDD2 (mini sata) in T430s

This is not a Lenovo problem, it is a problem inherent in connectors and expecially edge connectors even if they are plated with gold as these are.

 

Gold certainly helps because it is a noble metal and does not oxcidize. But in an environment surrounded by plastics, a little known problem occurs which can cause a connector to fail. The plastic outgases organic compounds that deposit on the gold edge connectors, and if they are not gas tight, ultimately these deposits can cause the contact to fail.

 

This is why unplugging and replugging the card fixes the fault, essentially this manuver sort of cleans the contacts, although not very well.

 

A much better and long lasting procedure is as follows:

 

1) After removing the card, use a standard pink eraser (*not* the more modern plastic erasers) and very gently rub it over the gold contacts on both sides of the card. Make sure there is no esaser residue left on the card.

 

2) Use a standard contact cleaning fluid (available from CRC) which usually comes in spary cans and spray a little on a paper towel. Then use the dampened part of the towel to finish cleaing the contacts. Then dry them with an undampended part of the towel.

 

3) Finally find and use another CRC product, 2-26, which is designed to essentially protect electrical contacts from degredation in unfriendly environments. Don't know if it's available any more, but no doubt CRC has an equivalent product. This will protect both the male and female contacts as well.

 

 

I've used this procedure quite a few times and once on a very old piece of audio equipment built with switches whose contacts were silver plated. Unlike gold, silver readily tarnishes (oxcidizes) and these switches are especially prone to failure because of that. Even more so since they are used for low level switching, sometimes called dry switching.

 

That particular peice of equipment has been running flawlessly for at least 25 years since I did this.

 

I did this on my T530 and don't expect this problem to ever occur again.

Re: Error 2101 Detection error on HDD2 (mini sata) in T430s

I tried all the suggestions in the forum but unable to correct the problem e.g. reinserting the ssd, upgrading to the latest bios, cleaning the ssd etc.

What solved mine was, I return back to the old bios which before I experienced such error.

For now its not showing the error but I will wait if it will come again.

So the main issue is the bios for me when I update it, that was the time this 2101 error started.

I have T440p.

Let me know if you have any other solution.

Thanks,

I still don't know what the solution is (none has worked so far, including Express Cache, althouhg it reduces frequency...), but if you have bricked, one of these sequences work:

1. go to BIOS setting and disable or enable Safeboot under security tab. (it doesn't matter which, just choose the opposite option of what is currently selected). This works most of the time.

2. If above doesn't work, tinkering around other boot and secuity settings (I can't remember which but have played with TPM and anti-theft) often helps.

3. As last resort, change HDD settings from AHCI to compatibility mode. This resolves the issue permanently but sort of kills the purpose of having an SSD in the first place, esp. if you (like me) have an msata on a T430 which already offers half the speed of regular SATA. Once booted, you can go back and flip settings back to AHCI but you'd have to then boot Windows in Safe Mode initially (Windows keeps changing the key combinations for safe mode, and I can't remember if there's an effective way of triggering it at boot in Win 10. I swith to diagnostic boot from BIOS, switch on my machine, know SSD is now recognised, then get an error, restart the computer a couple of times... and on the third or fourth restart Windows 10 "automaticlally" figures out you must be having boot issues and offers you list of menus from which you choose advanced options, advanced boot options (or similar wording), it'll give you a list, press continue, it'll restart and list a few items, chose 4 for safeboot. Once in safeboot, let the computer idle for a few minutes and reboot normally.

Same issue on my T460s.  Lots of 2101 errors, especially coming out of hibernation, or after it sits idle for a while.  I updated BIOS, Lenovo drivers, removed the M.2 and cleaned the contacts, wore garlic around my neck...everything I read.  I was getting that error, and some random BSOD's several times a day.

 

I was about to buy a new SSD M.2 and decided to take one more shot at cleaning.  This time I took a look with a loupe.  Look at this white corrosion bridging the contacts where the M.2 socket is soldered to the mobo.  Socket on the left is unused and there's a big difference.  I tried air - lots of it.  It didn't move it at all.  So its some corrosion, and its not on the contacts the M.2 touches.  I just sprayed contact cleaner on a toothbrush, and brushed it like your dentist tells you to brush.  It took several applications, but it now looks just like the un-used socket on the left.  I haven't had a 2101 for 3 days now.

Well, ^^that^^ was over a month ago. No 2101 errors, and no Unexpected_store_exception BSOD's. I felt like a genius.

 

They came back a couple weeks ago, now its several times per day. M.2 slot is still very clean. So now I saved an image and put it on a new SSD drive. This is a Samsung 256 with an NVMe interface (My T460s will go either SATA or NVMe...not true of all computers). If it's been a few months and I haven't posted back here, you might assume the new drive was the fix.
