16G cruzer blade verify fails

i keep getting with my 4 years old cruzer blade noCRC match.i started happening like 1 years ago.i mean like 1 error then i verify my writes with teracopy…now i need to make serval attempts,before i can sucessfully verify my data after being writen.also if verify failes i cant find of my files,if i writed them.

i tried error checking using windows and i dint find any issues…

It could be the drive is failing or the contacts in the pc’s blade slot are dirty.  Have you tried it in a different pc?
