|
|
<P>The procedure principally involves finding the data on the raw partition
|
|
device and making it visible again to the operating system. There are
|
|
basically two ways of doing this: one is to modify the existing file system such
|
|
that the deleted inodes have their `deleted' flag removed, and hope that the
|
|
data just magically falls back into place. The other method, which is safer
|
|
but slower, is to work out where the data lies in the partition and write it
|
|
out into a new file on another file system.
|
|
<P>There are some steps you need to take before beginning to
|
|
attempt your data recovery; see sections
