Rewriting data on hdd and backup!

[Deleted member 2049969]

Hi. I want to backup a large amount of really important data. I got a new western digital 1tb (WD10EZEX) in which I will copy all the data. My previous disks are: 1)wd5000aakx-001ca0 (500gb) 2)wd3200aaks-00vya0 (320gb) 3)seagate st3320613as (320gb). The data on these disks has remained unchanged (not unused) for a long time (maybe 8-9 years for some files). The files are mainly movies, photos, music or programs and games for installation (not installed, downloaded). Apart from copying the files to my new hdd, I read that it is good to REWRITE the data on my old hdds if you want them to last for a long time. So, I ask whether this is true and if it is, will a quick format work or a full is needed. (What I mean by rewriting is that you first transfer the files to another hdd (my new wd), format the old disk and then transfer it back so the bytes are written again with the original "magnetic strength" or something like that). I will appreciate any help.

P.S: Any advice for backuping my files more safely is welcome, these files are too important for me, thanks!

Re-Writing is mostly a bunch of hooey.
The only reason it adds value is you test the disk and data by doing it. You also test your data when you back it up (can it be read)
Instead just use good backups and check your current disks.
Begin with the following:
(assuming testing D:\)
open CMD window
type D:
then press enter
type chkdsk /f/r
then press enter
