remove severe badsector

I have many hdd with severe badsector (quantum, seagate, fujitsu, maxtor, samsung, HP, WDC, toshiba, hitachi).
I used MHDD, Victoria, LLF, PC3000, but the badsector is remain.

Have someone experienced with the kesender ? (http://www.yec-usa.com) Hardware and software to clip function will mask any uncorrectable bad sectors.

Please share with me, please

thanks

If bad sector's are physical , is the disk to the expulsion .

There is a way to remove bad sectors there can be physical bad sectors but there is a way to remove them also there can be some modules curroption . There is a way to remove physical bad sectors add them to plist .

I use PC3000 to remove badsector and I do step by step :

1. erase defect HDD in P-list and G-list
2. formating/LLF HDD
3. logical scanning/PC Defectoscope/rellocate badsector, but the error
message : overload badsector
4. selfscan, but I can`t do selfcan for all HDD, etc : maxtor poker

Most of the time severe bad sectors occurs due to firmware curruption chk the firmware struture of the drive there may be a curropted module rewrite it then regenerate translator clear glist and plsit .

then chk the surface !!

I am very thanks to rameez & bigolsen for your answer,

But I will know the function of kesender, what the tool can make HDD with severe badsector become no badsector (http://www.yec-usa.com) or its tool better than PC3000 for repair severe badsector.
