Hello Forum members,
I am having an issue with a seagate 4TB sata hdd(MN:ST4000DM000-1F2168,SN:Z304N25D) i bought online(don't remember whether it was used or refurbished??)that the "SMART" feature tested ~"OK" in Victoria disk utility(?) ; however i keep getting disk is not ready errors after HDD regen scans for bad sectors(it also drops out of sight sporadically when attempting to correct bad sectors,delay problems!!)!!

what i would like to do is do a data recovery(software based recovery windows utility only!) or reformat operation but have been stifled by windows 7 explorer not responding,etc when attempting to recover any files via windows recovery software!?!?

I would like to know if the seagate bad sector problems are hdd platter surface defects or firmware/RW head related??
