did someone meet the error ID 22 in S.M.A.R.T monitor? I have googled and the problem should be caused that hard drive is filled by helium:
"They responded by saying that attribute 22 is the status of the Helium in a drive. It is a pre-fail attribute that trips once the drive detects that the internal environment is out of specification."
I suppose that backup is recommended now. Do you think that reseller should accept a complaint?
Thank you in advance
