The Cisco 8300HD PVR has a simple IDE
controller built-in. There is no need to pre-format
or prepare the hard drive. Simply install it as is
and the PVR will format and partition the hard
drive for use.
Running out of space on your Cisco/Scientific Atlanta
Explorer 8300 High Definition PVR/DVR? You could
simply and easily just swap out the hard drive!
Like many of you, I can never seem to have enough hard drive space on my
cable PVR. Depending on where you live, you might also call it a DVR. Since I
own and don't rent my PVR and because it was well past its warranty period, I had
nothing to lose so I decided to rip off that "void if removed" seal on my unit and
Since it was long past its warranty period, I knew that it wouldn't hurt to open up the unit and peek inside. Before I
could get started, I was faced with those pesky Torx security screws. First stop, my local electronic supply store. I
picked up a set of Torx security bits that fit into my power screwdriver. I was lucky and picked up a set on sale at
Princess Auto in Toronto (available nationally). Total cost was about $7.50. If you don't have easy access to a kit, you
can have success by using a small screwdriver or awl and simply pry off the centre security pin. It might take some
time, but it will work.
With that out of the way, I opened up my Cisco Explorer 8300 Cable HD PVR/DVR with its 160GB hard drive and
couldn't believe what I saw.
The operating firmware for the CIsco 8300HD is
on the motherboard. NO FIRMWARE or
operational control is on the hard drive itself.
The Cisco Explorer 8300HD PVR while discontinued years ago, is still quite popular and widely distributed by many cable companies in North
America. A little bit of online research revealed a few things that made it that much easier to find a suitable hard drive. The SD and HD units use
exactly the same hard drives. Initially the units shipped with 80, 160 or 320GB hard drives. The last versions of the 8300HD shipped wth 500GB
hard drives which was the physical design limit of the unit. If you have an 8300 with a 500GB hard drive. You've reached its limit and sadly
cannot add any additional space. If your 8300 has an 80, 160 or 320GB drive, you can replace it!
The OEM drives that shipped with the Cisco
8300 PVRs were 5400 RPM. They also use the
older IDE controller for the I/O. In my case I
was able to purchase a used 500GB hard
drive from a friend for $20.
The drive replacement is very
straight-forward. The PVR has a single IDE
control cable and a standard power plug.
Be sure you ground yourself (drives hate
static electricity) and proceed to unplug your
PVR from the outlet.
Any 5400 RPM IDE drive will work. It doesn't
need to be formatted since the Cisco
hardware will look after reformatting the
drive for use as a PVR.
I use this 33-piece Torx Security set that I picked up at Princess
Auto in Toronto. It has both Torx and hex security bits.
While I have not replaced or researched hard drive replacements for other Cisco PVRs, if you own your PVR like I do, swapping out drives
is always an alternative to PVR replacement. Some of the newer drives use SATA internal interfaces. Installation is essentially the same. If
you rent your PVR from your cable provider, opening up the unit is not a good idea. If you're renting, ask for the newest and greatest
version available. You're paying for it.
Here are the simple steps to installing a new hard drive in your Cisco 8300HD PVR:
Remove the Torx security screws on the back of the PVR.
Locate and disconnect the power plug and IDE control cable connector from the hard drive.
Unscrew the hard drive from its harness using a Philips screwdriver. The harness comes off by removing the cross-member support.
Reverse the steps with your replacement drive.
Once you confirm everything is tight and ready to go, turn on your Cisco PVR. It will detect the replacement drive and begin a drive
format process. It will take approximately 30 - 60 minutes.
During the formatting process, the display will cycle hexadecimal information (gobblygoop to those who are non-technical).
Once the format process is complete, the display will revert to the clock and auto-tune to channel 1.
That's all there is to it. Enjoy.
