Hard drive multibit-ecc startup error

what does this mean when its on the hard drive? im for certain it is since im running on my backup hard drive atm

 

ssd hard drive
custom built pc
+64 bit windows 7

pc crashed then failed to boot

upon trying to boot i had to insert windows cd to even get a boot from cd drive then found out it wasnt reading one of my hard drives (the main one I was using)

 

Seems to be certainly the hard drive.

I run two ssds

The second one was fast storage (worth it even if small)

When it wouldnt boot and i did the windows cd...

It only seen one hard drive (backup) without windows was able to install on this one and run the same pc with spare hd

Not sure what tests you would run for ram

 

I don't see an edit

I meant to say storage drive instead of (backup) in my last post

 

While your subject says harddrive, "multibit-ecc" suggests RAM.

To test your RAM, if you have more than one stick, you can pull all but one and run with that to see if you get the error. Then swap sticks and hopefully, through the process of elimination, determine if one is bad. Just make sure you unplug your computer from the wall and touch bare metal of the case interior to discharge any static in your body BEFORE reaching in to remove or replace the RAM. This puts you and your computer at the same potential, eliminating any chance of a static spark near your RAM that might destroy your RAM or other nearby sensitive devices. Touching a doorknob or sink faucet, for example, puts you at the same potential as the doorknob or faucet, not the computer. So touch bare metal of the computer case's interior.

You can also run MemTest86 on all your RAM. Allow the diagnostics to run for several passes or even overnight. You should have no reported errors.

Note, however, that software based RAM diagnostic tools are good, but none are conclusive. If they report errors (even one) the RAM is bad. But it is not uncommon for no errors to be found, but the RAM still fails when installed in the computer, or when paired with other RAM. To conclusively test your RAM, you need to use sophisticated and very expensive test equipment, like this $4,000 Eureka Express DDR3 DIMM Memory Module Tester.
