I have been losing external hard drives lately.
By that I mean they are melting down. I'm
pretty sure that heat is the problem. Most of
the external drives I have are either in housings
that have no fan or have a really puny little fans
that I can hardly feel air flow from.
I thought about the new desktop interfaces that
allow you to plug a bare drive into them. You can
get one that connects via eSATA. You can
also get a 51/4 inch housing that goes into
an empty bay on your desktop that takes
removable hard drives.
I went another way. I took an older
(Athlon 64 2800) computer and installed
2 - 1 and half gig sata drives on it and
Ubuntu Linux. I configured Raid 1 Disk mirroring.
I then transfered 800 gig via network neighborhood
via ethernet. It took two nights. Half one night and
half the other.
Now I'm thinking that I can pull one of the mirror drives
and take it off site. Then replace that drive and
tell the Raid software to rebuild the new one. The Linux
RAID mirroring does not use any special
file format or compression. It is just ext4 which
is a standard Linux format so the off site drive
should be easy to mount and read.
I'll have to test this in Dec.
I thought about doing this under Windows on my
main workstation, but reading a bare single RAID
drive is very tricky under Windows. Computer motherboards
that have RAID chips don't do true RAID and the drives
can be unreadable on a different motherboard. I have
no idea about Mac and RAID.
