a few days ago a friend advised me to use KillCopy (http://killprog.narod.ru/killcopye.html) , a program that allows u to overview everything u are copying easely.
now while copying suddenly my computer started to freeze for short amounts of time and hard noise come out of my soundboxes.
After restarting the problem went away until i tried to copy or cut the files. Only thing that worked was to delete the file.
After using powermax on both drives (one maxtor 7L300R0 and one maxtor 6B300R0) it said it was broken (was a burn test).
scanning both hdd's froze halfway through
performing a quick format on them worked
performing a normal format froze aswel

if i quick format them and fill both of the drives some files have the error (that computer freezes etc).

could it be possible that KillCopy totally destroyed my hdd's or am i able to repair them?

I am afraid it was not KillCopy that did it.
try zero filling the drives.

Use MHDD or victoria to scan hdd for defects .

After searching and running MHDD i've seen that some sectors of both hdd's are ruined.
And because it are both maxtors i can't block the sectors and replace them by spares because maxtor doesn't have spares :<
But good news is that i've still got warranty for both ^^

@pepe: tried zero filling the drives but didn't work because of the total damage of the sectors.

thx for feedback

what spares are u talking about ?

The guy at my computer shop said:
Hitachi and Seagate have got spare sectors on their disks so that when u have total damages ones u can block them and use the spare ones instead. But maxtor doesn't so damaged and unreplaceable.
Or is everything i'm saying here blabberish?

The manufacturer gives a Glist for replacing bad sectors with the good one this applies to all manufacturers of the drives including Maxtor and Maxtors Glist can take upto 600 to 1000 sectors in Glist .

So some part is rubbish that maxtor dont have spare sectors it does with two
modules Glist and Plist .

Where Plist can hold upto 30,000 bad sectors but for adding defects to plist u need pc3k .

So when u buy the hd it can have some bad sectors that are already added to the Plist while when u use the drive u can add bad sectors to the Glist?
And when u add the sectors to the Glist u can still use the total amount of data on the drive?
Is it possible to add sectors to the Glist yourself with only software or do you need hardware aswel (example: pc3k)?
Still going to send the drives back to because it's the easy way for me (knowing i still have warranty and only use the drives for storage).

Yes for adding sectors to Glist use Mhdd and Victoria .

Good to know if i have problems in the future
Thx for the good feedback.
