that'd depnd on the problem of what *-you-* mean by "died" vs what's

dammagd in what way ??? ( how do you know that )
- did it make funny noises when it starts up that is different
than the normal startup noises
- if the head is bad ( damaged )... you will NOT be able to
read anything with it
- if the platter is intact, you can replace the head
and use a different replacement head assembly and read the disk
as if nothing broke ( but you need a special clean room to do
replace the head )

as others have noted dd_rescue might help too

buy what's on sale ... $0.50/GB or less
- maxtor - any newer than 16GB
- seagate - any
- ibm - stay away from those deskstars made in thailand
- western digital with 8MB buffer or more

the reason why tom-dick-n-harry has no problems with maxtor xxGB disk
is because they bought it at big-famous-store
the reason why sally-mary-jane has nohting but problem with the same
identical xxGB disk is because they bought theirs at the local pc-store
or me-too website and had it tossed around like a concrete brick during
shipping, handling, inventory, storage, etc, etc, etc
if you buy at any random place, you will have random disk problems
if you buy from "good places", than any and all disks should be
practically identical assuming they all have the same 1yr or 3yr
or 5yr warranty
--------------------
- do NOT compare 1yr warranty disks with a 5yr warranty disk
--------------------
which is like comparing a house to the mars
( nothing to do with each other )
- if you do NOT have a properly cooled hard disk ( with a working fan on
it ), than you're asking for it to eat your data one day as you sleep
- i bought 1000's of drives over the last few years
