RESOLUTION:

I erase the drive completely following the security measure "Zero Out Data" and then reformat the drive. According to what I read, by following the zero out data procedure, the computer checks the drive and isolates possible structural errors in the disk ( donīt know if it is true) I had everything already backup through Windows as explained originally.

After I reformat the drive everything is working OK. I have done the tests again (Disk Utility and Disk Warrior) that showed the drive to be in perfect order. So probably the error was caused by lack of sufficient free space in the disk ( 30 highly fragmented GB for a 1TB computer) that made OS X incapable of handling new information and was deleting key elements (?) in short a fragmented and saturated disk. However still do not understand why most tests could not complete or showed info relating to structural damage and now the same tests are saying everything is OK...

So if anyone goes through something similar, try erasing and formatting the drive, see how it goes.
Again thank you chscag for your help.
