W520: PNY XLR8 240GB SSD with error "2100: Detection Error on HDD0 (Main HDD)"

When I try to boot my W520, I get a BIOS boot up error : "2100: Detection Error on HDD0 (Main HDD)". I am using PNY XLR8 240GB SSD.


It worked fine for a month.


I also have PGP installed and whole disc encrypted.


I installed an update of Intel Management Engine Firmware and Intel Chipset, both are the latest from lenovo site because I was experiencing expreme slowness from my harddrive. Programs would freeze. Webpages would take forever to load..

The next time I rebooted, I got the error. If I leave the SSD out for a bit, and put the SSD back in, the disk will work for some time... but on next reboot, it is again detection error..


TRIM is enabled on my system. I am not sure how the SSD died so quickly.


I am back to using my HDD but I am not happy. I want a solution... is this a intel chipset issue? Intel IMEI issue? Is  the PNY SSD just a bad model?


I've googled plenty and dont really see a solution. Sometimes there is a firmware update.. PNY has no firmware updates for my drive.. I don't see anybody else using PNY on their W520, but plenty of people are experiencing Error 2100 with SSD on their W520.. somethings fishy..


help please! thanks in advance !

I don't have a ThinkPad W520 or a PNY SSD, but could it be simply that the SSD is coming loose inside the ThinkPad's chassis?  I suppose this could occur if a 7mm high SSD was inserted into a 9.5mm high 2.5" drive bay with a ~2mm spacer to "pad" the unused vertical space.

Product Dimensions: 3.9 x 2.8 x 0.4 inches ; 3.2 ounces


.4 inches is 10mm? So I dont think this is it.. altho it does feel a bit loose. I'm going to check this out now. See if I cant get something put in there to keep it firm. Maybe ducktape a piece of paper or use some foam to make it stay tight.


Is the W520 known to have an HDD or SDD (9mm) be loose? Do people shut down their machines when they move about? or is Sleep Mode enough?

No go, the drive is in there pretty firmly, a tech support to PNY said they are going to replace my drive.


They came to the same conclusion I did - which is that the drive is toast.. Smiley Sad


Drive slow downs and eventually unable to detect points to this.. I was hoping for some firmware update. I am really surprised an SSD died because I thought the whole point of them - no spinning parts - would make them last longer.. but there is some sort of logic board and maybe the flash drive itself went kaput.. who knows. 

They do have 3 year warranty on my mode and i'm happy to take it. Luckily my old HDD was still around and works.. so thats what i'll be using for the next few weeks while I ship this to them and have them send me a new one.


I asked about Advanced replacement, which is when they send me a new one before they recieve my current ssd. They said the Advanced replacemenet costs $30, and they would need credit card info to place a charge of the original amount for the drive incase I didnt send in the drive too. So it would cost me $30 plus temporary $100-150 or so... which I opted not to do... So I wait now for a few weeks. I dont know if I'll get another PNY drive in the future. OCZ has faired pretty well for me, I've had 3 of them work on desktops/laptops flawlessly.
