i think besi buruk     

really pls let me know where

Red is for NAS and/or RAID.
AV-GP is for CCTV.
Green is for normal but reduced energy usage.
RE4 is for enterprise usage.
RM200 sounds ridiculous, at least for common HDDs that can be had for less than that. Maybe they're also stealing the data from the HDD? It is possible to extract data from dead HDDs. So dead HDDs that once belonged to a finance department, celebrities or other people of significance could be valuable.
How old is your HDD before it died? The F1 is a pretty old model.
If you need the data on the HDD, please do not send it back to the manufacturer for RMA. The manufacturer will almost certainly give back another HDD, with a different serial number and without your data on it.

Ahem and JAV dont worth shit thesedays its all over the net able to stream pro-actor you want. I guess famous people politicians might, as he said data of financial importance.

The only way you can guarantee that your data is not casually retrievable without authorisation is to use full disk encryption (FDE) and a good password. But you'll have to do this before the HDD died.

Truecrypt is a rather popular third-party FDE tool, or on Windows you can use Microsoft's Bitlocker. Don't do partition or file encryption, as copies of your data can be leaked to unencrypted portions of your disk; do full disk encryption. Be warned however, if you lost or forget your password, the probability of cracking it is very low unless your password is weak. There was an unfortunate fellow forumer who had forgotten his password and all his data was effectively lost.

If the HDD is already dead, then the only secure way to destroy the data is to dismantle the HDD and damage the platters. Of course, this will void any existing warranty.

Do note that the HDD's PCB has some value in the HDD repair market. Sometimes the HDD failure is due to damage on the PCB and replacing the damaged PCB might restore the HDD back to working order. They'll need some rather detailed information however, as PCB incompatibility is also rather high.

I guess you can hammer your hdd plates after you have dismantle them as they were being stored magneticly and put it under a magnetic field
