Olde Bill The WD 500GB/32MB Cache drive that originally came with my 8642 died and I successfully replaced it with a WD Black 1TB Performance Desktop Hard Disk Drive - 7200 RPM SATA 6Gb/s 64MB Cache 3.5 Inch - WD1003FZEX. It formatted and came up while I was putting my tools away (including the $5.99 Tamper Proof Torx driver set from Princess Auto).

The unit is now running Navigator and isn't showing the same sort of lag that we were experiencing before Christmas.

57 @CKramden : The 8642 is really slow with Navigatr. If you search the Navigatr threads you'll find similar comments from all those who recently were forced to use Navigatr instead of SARA. RTN firmware was pretty slow as well on the 8642s which are simply underpowered for this firmware.

A reboot will sometimes restore a bit of speed, but don't expect SARA speed. Depending on how you approach things with Rogers and depending on your overall package, they have sometimes upgraded people to the 9865 or even 4K PVRs after being forced to use Navigatr. This would be a free rental for a year or two perhaps...

Happy to Find This Site

Just a shout out to all who have participated in threads detailing replacement of hard drives in Rogers Explorer 8642 HD PVR's.
I am not inclined with this stuff, but thanks to you I have replaced the hard drive and works just dandy. Went with the Western Digital 1 TB blue. drive. Hums a bit, but cured this by raising unit off the cabinet.

Also would like to find others with Rogers PVR service that has slowed down to a crawl after implementing their Navigatr Guide program. Not sure if it's my old box or Rogers, selections taking forever to change.

Thanks to all and expect to learn a fair bit here.

57 RTN was the "red and black" firmware between SARA and Navigatr. Some people managed to stay on SARA with their 8642s until very recently and then were "force-downloaded" Navigatr.

Alexandrej Indeed. Thanks.Not sure what RTN firmware was.

Thank you for your post. You're actually running Navigatr firmware.

Alexandrej Hello team,

Just updated my busted 500GB iHDD on my Netbox 2.0 8642HD3 with a WD Red 1TB WD10EFRX.

1. Are you using RTN or SARA firmware?
RTN (not SARA for sure).

2. What was the size of the original HDD (160, 320, 500)
WD Green 500GB WD5000AVDS

3. Did you do anything to the drive before insertion (computer format, change dips, etc).
Absolutely nothing. Unplugged old iHDD. Took the WD red out of the plastic pouch and plugged it in. Did not change and jumpers, etc.

4. Make/model of new drive

5. Firmware version number dated June 9, 2017

6. Anything else you may feel is relevant
The iHDD has failed but the box was still working. The only issued is I could not record anymore. Every time I tried to record, I would get the following message "Recording failed - duplicate recording failed" despite the fact that in the "my recordings" menu, PVR showed no recordings and no scheduled recording as well as PVR usage at 0.00%.
Called Rogers tech support yesterday evening and after doing basic checks, they wanted me to swap the box I owned with a rental one... nice try. They did not know what was the problem. They told me to have the box checked at the Rogers store to see what was the problem. Of course, when I went to the store this morning, they did not know ho to check the box. So my gut feeling was the iHDD had gone south and reading this thread from the beginning, it appears I could change it fairly easily. So I did and everything is fixed now. I can record two threads at a time and schedule recordings.
I plugged the iHDD in, plugged the TV Cable feed in the Cable in connector, so the box could download the OS onto the iHDD automatically. Plugged in the box and just sat back and relaxed. The box restarted a few times and everything came up nicely by itself. Not tweaking of any sort.

I hope it helps anyone looking at upgrading their Netbox 2.0 8642HD3 with a WD Red 1TB WD10EFRX.

Have a great day!

pgcairo Just installed WD Blue WD10EZEX 1TB 7200 RPM SATA 6Gb/s with 64MB Cache. Without the cable connection, it simply ran thru the formatting over and over. Plugged in the cable and it completed both the formatting and the cable reboot in about 4 minutes. Up and running.

jasonchan I tried installing a Crucial MX300 525GB SSD; but it put the box into a reformat loop. I settled on a traditional HD - Toshiba MQ01ABD100 1TB - larger and still quieter than the original 500GB WD drive.

Just replaced the hard drive in my nextbox 8642, 500 Gb. I installed a Seagate Desktop HDD 1TB 3.5" SATAII 32MB Cache OEM Hard Drive (ST310005N1A1AS-RK), it has a 32mb cashe. It installed and booted up easily about 30 minutes. It seems to be working well and is reading lmost the full terabite.

Widster One day in and everything is working well. I can confirm that I am using a 64mb cache. Looking at the original post re: 64mb I don't think that it was ever proven that the cache size was the problem as there were other variables in the mix. If any problems arise I will update the thread.
Another observation, the pathetic Rogers Interactive Programming Guide is working twice as fast as before although it is still really slow. I own a second 8642HD that I bought at BestBuy a few years ago and for whatever reason it continues to use the old Programming Guide. Nice and simple and fast.

The hard drives that shipped with the Cisco 8642HD units has 32MB cache vs. 64MB cache. In 2012 when these units came out and people began swapping out the hard drives and tried to use 64MB cache drives they wouldn't work and you had to use a 32MB cache drive, which for the most part do not exist anymore. So good to hear someone used a 64MB cache drive and it seems to be working. Perhaps they solved the software flaw.

Widster Went out today and bought a tamper free torx set from Princess Auto for $5.99. Stopped at Computer Canada and grabbed the WD1003FZEX. Plugged it all in. It display ER62 then ran through r numbers for a while. I came back in about 20 minutes and the time was displaying. I gave it another 10 minutes and pushed on. It works. I need more testing but the ribs on my BBQ are more important at this time.

I installed this WD10EFRX with 64MB cache and it ran but after a while wouldn't stop chattering. I didn't know 64MB cache was an issue!
