[comp.sys.mac] Hard Disk Partitioning and Disk Recovery

jalden@eleazar.dartmouth.edu (Joshua M. Alden) (09/02/89)

Hello.

    I work in User Services here at Dartmouth College, and on any given
day we get one or two hard drives that have crashed for a variety of
reasons.  It has come to my attention that most hard disk partitioning
makes it exceedingly difficult, if not impossible to get any data back
from the bad drive.  This is because most partitioning schemes actually
create one large file and then save everything for that partition in
that file.

    Now, I use SilverLining with my La Cie hard drive, and I've never
had any problems with it.  It has always been treated as though it were
3 disks, which is as it should be.  But I would like to know how
SilverLining's partitioning scheme works.  Is this what people mean by
"true SCSI" partitioning?

    Just what the heck does partitioning involve, anyway?  I use it
because otherwise it takes ages for a simple Finder-copy to update the
desktop file, and the desktop file begins to approach that magical size
at which it self-destructs.  Am I setting myself up to take a fall here?
(A small one, because I have it completely backed up, but still...)

-Josh.

Josh,

"True SCSI" partitioning is basically partitioning that occurs when you 
initialize the drive for partitions, as opposed to a "standard" drive.  Other
partitioning schemes involve the creation of an invisible file at the root 
level of one's hard disk and via the particular software's INIT or DA that
allows the Mac OS to treat this file just like any other volume.
