The down and upgrade process from a Set Top Box, an 8300 HD.
When you have a bad drive in your STB (160Gig) there is a way to fix this.
We tried a 40Gig and a 300 Gig and both will work after the download.
You are not allowed to do this unless you own the STB.

40 Gigabyte
300 Gigabyte Download
in progress Do not unplug
Almost done
1st boot

The DHCT screen Loading the guide
Channel 203
Channel 242
Hmmmm no access to the recordings
It looked promising but we waited 15 minutes and pulled the plug, Plugged it
back up and and the download started again.
You have to go to this process so be patient. After the download of the code the
same thing happened but now we saw the following.

Here the partitions will be formatted. And another reboot.
Power light

Channel 800 and the recording list.
So far so good we are now able to see our recordings list. Try to record
something and open the list again.
We will go to the diagnostic screens to see if our new HD is visible.

The time and the blinking envelope, and our HD is visible.
The 500Gbyte hard drive test/format below.
I ran in a few problems, This was a hard drive used in a PC so it wasn't a
"clean" one.
It formatted 5x the drive during the whole episode. but it did the last time the
"HDDF and the HDD-" a good sign that the partitions are set. All the rest is the
same as the pictures above.
A 2nd hard drive on a ribbon cable with a double header from a PC didn't work
correct.
No errors but it didn't saw the smaller 160Gb hard drive or the other way
around.
2 similar hard drives 160Gb seagate was giving a failure on the display,
swapped jumpers around and took them of. No difference at all.
Conclusion it is better to take one big hard drive and connect it, EIDE
internally or eSATA externally.
