HC: There are lots of companies offering hard disk drive (HDD)
enclosures, and with a variety of interfaces including FireWire 400,
FireWire 800, USB 2.0, and even eSATA, but you *cannot* connect such a
drive/enclosure combination to a FireWire-equipped DV or HDV camcorder
and record directly to the HDD because the protocols involved are
vastly different.

DV over FireWire 400, for example, is IEC 61883-2 while a HDD over
FireWire is SBP-2.

The reason why your idea won't work is because the camcorder has no
way of controlling the HDD, let along formatting the data properly
into an .avi or .mov file, for example, let along an understanding of
the file system (FAT32, NTFS, etc.) into which the HDD's partition has
been formatted.

HDDs in external enclosures only work because of the presence of a
"bridge chip" mounted on a small PCB (printed circuit board) within
the enclosure that performs the required protocol conversion. The
reliability of any given enclosure tends to be dependent upon not only
the ability of the enclosure to keep the drive cool temperature-wise,
but also the quality of the particular bridge chip used. A bridge chip
with buggy code is not a pretty sight. (I've been there and done that,
but am so far very pleased with a 400 GB Glyph Technologies GT 050Q
external drive that I acquired a few weeks ago.)

The closest thing that I can think of that meets the requirement that
you've outlined would be a not-yet-available product called the
Catapult from Bella Corporation. The Catapult is a small box which
sits between your FireWire-enabled camcorder and a HDD with a USB 2.0
port. The Catapult will contain firmware to receive over FireWire the
DV datastream from the camcorder and control the USB-attached HDD,
which is user-supplied and could even be an Apple iPod. In effect, the
Catapult will almost look like a host computer to the HDD.

As an alternative to the above, you could do one of two things: a) use
a computer -- notebook, desktop, or workstation depending upon the
circumstances of the shoot -- and "capture" (transfer, actually) in
realtime over FireWire to the computer's HDD using any number of
programs and in the file format (wrapper) of your choice or b)
purchase a dedicated HDD designed especially for this purpose from
companies such as Focus Enhancements (FireStore DTE), MCE Technologies
(QuickStream), ProCon Technology (nNovia QuickCapture), Shining
Technology (CitiDISK), etc.

Great, Mike, another link to add to my HDV Web page! :)

(P.S. It's been done.)

Let's hope that it's not a vaporware product.

The interest is quite understandable given that it's a lower cost
solution than even the Shining Technology product, and you have your
choice of drive.

Agreed.
