<DIV dir=ltr>hi<BR><BR>one day this week, i started my computer, it behaved
very strange - i had a blank screen for about 2 minutes before i got the boot
screen, then it continued to boot from ... network<BR>the reason was that the
hard drive has died. it wasn't even recognized by the bios.<BR>the computer
was 2 months old, so i replaced the hard drive.<BR><BR>when a hard drive dies
and it is under warrenty, we need give the old one when we want it
replaced.<BR>usuallyon the hard drive we have some personal things - pictures,
documents, or confidential data if it belonged to a company etc...<BR>assuming
the data is backed up (backing-up is an issue for another thread), we are left
with the possibility of someone retriving data from the damaged drive.<BR>and
when the drive is damaged, we can't even access it to erase that info before
replacing it with a new one.<BR><BR>so i though of a solution - use a crypto
FS.<BR>but there are many problems with it.<BR>the practical problems are at
least:<BR>1. i do not know of a major linux distibution (i.e. redhat/ubuntu
etc... ) that fully support crypto-fs out of the box, so if i use it, i will
need to do manual changes every time i upgrade the system.<BR>2. it is not
really secured if the key is stored on disk. however if the key is not stored
on disk, then the computer can not acces the data without human intervention,
which is not good either when it comes to servers.<BR><BR>and guys/girls, take
my advice and back-up your data every short while. everybody thinks it will
not happen to him. but it does. it is just a matter of
time.<BR><BR>erez.<BR></DIV>
