You can use the 8300HD as a tuner, and/or replace the iHDD if you can find one. (It needs to be a PATA, not SATA drive). PATA/IDE drives can be relatively expensive for relatively small drive sizes. You may wish to consider putting the money towards a 9865/NB3 instead. I would not recommend an 8642 as it's very slow under the new Navigatr firmware.
You may also be able to get some $ selling the 8300HD online, or use it as a tuner elsewhere in your home.
Yes, I can hear the drive spinning. No clicking though. Thanks for the reply. I'm afraid I may need to buy the NB3, this 8300HD I have was one of the refurbed units from the shopping channel, it has worked well up to now.
Sometimes a second or third reboot may get the iHDD working for a while. I had a similar issue with a very old 8300HD, which I'm now using as a tuner only. At first, several reboots would "wake it up", but after several months I could hear that the iHDD was not functioning properly - trying to restart every few seconds (chirping noise). Eventually the iHDD was completely silent.
I see PATA/IDE drives still available for under $100 (but no really big ones). There is a thread on this board on them and how to replace. You will need a special bit for the tamper-proof Torx screws. I would certainly try that before venturing into the mess of Nextbox and Navigatr and I have a spare drive in stock for the purpose.
I have an 8300HD+ with a dead internal hard drive. I'm wondering if I disconnect the internal drive and use only the external will I be up and running again. The IDE hard drives are hard to find and a compatible external SATA hard drive to use as a primary hard drive rather than an expansion may do the trick.
I recently did this upgrade to my 8300HD. (160gb to 500gb WD pata drive.) It did the countdown - arrived at HDDF but I 'sat tight' and it continued on and rebooted.
It has been in use for about 2 weeks now and all seems well. This is a pretty easy upgrade and worth trying if you've got a drive around or can get one at a reasonable price. A #10 torx security bit and a phillips screwdriver and you 're good to go.
