Re: Generic Linux question

Dear Marc, 

If you want to mirror content, I suggest you format it, and then use rsync 
or a simple cp -a.
If you want to mirror it completely, to the lowest level, and if the 
drives are identical (model, size, make,etc), then you can 
___CAREFUL__ THIS MAY DESTROY ALL YOUR DATA </warning> (on drive hdc at 
least)

dd if=/dev/hda of=/dev/hdc
to mirror everything on hda onto hdc, including boot sector, partition 
table, etc... 

do man dd first just to see what you are playing with.
if you do <DON'T DO> dd if=/dev/zero of=/dev/hda it will trash your disk
for example http://lists.slug.org.au/archives/slug/2002/04/msg00575.html

Other than having to be careful with what you type, dd is rock solid (of 
course) and will do the job better than anything else.

If speed is important, play with bs= option (to match cluster size of the 
disk).

Ah.. and in future use http://www.auroralinux.org/#mailinglists

Regards,
Silvio
