My HR21-700 has been giving me a few freezes, like a drive issue. I'm using an external 2TB WD20EADS in an eSATA Antec housing (as was recommended here about a year ago) about 25% filled. I did a RB reset, was distracted reading emails when I looked up the DVR said it was formatting the drive... lost all my programming and scheduled items, kinda suspect the drive is on the way out (but only in use 13 months, I thought the WDs were good drives). I have a DTV TIVO unit thats lasted over 6 years.
The mistake you made was using the red button. The proper way to reset an HR with an external device is to unplug both the power cords from the HR and the external device and then plug in the external and wait a bit and then plug in the HR. NEVER do a reboot with an external connected by using the RBR method. Haven't touched that red button for a long time and haven't had any problems.
The EADS were the best that WD had when we recommended them. We had no way of knowing how long they would last. Now the best is the WD EVDS line of HDDs. Specifically made for DVRs.
So I power down and disconnect the external drive but the HR21-700 now dies with a 14-174 storage device error. Hmmph... this internal drive was used for maybe a month at the most.... so I guess they are failing regardless of whether you use them or not.
You gotta remember that the internal drive still runs when you connect an external HDD. And with a 21-700, as soon as the HR recognizes the external HDD the fan shuts off inside the HR. If you check the temp of a 21-700 with an external HDD, you'll see 77 degrees. That means the fan isn't running and it's gonna read 77 degrees no matter how hot it gets. The 20s don't work in this manner. When you hook up an external HDD to a 20-700 the fan keeps running and you get the proper readout of temps inside the HR.
Anyway before I call DTV for a replacement DVR, could i have done anything wrong that caused the 14-174 error?
Yup. You never want to use the RBR method or the Menu Restart option with an external device connected. You might get away with it or you might get the results you see before you.
What's the latest on the best 1-2TB drive for these DVRs? Anyone go through the WD warrantee process?
Again, any WD EVDS model HDD. Never had to use the warranty. My EADS have been running perfectly for over a year. I've switched to buying the EVDS model now and am putting them in Thermaltake docking stations rather than the MX-1s.
Is this a drive thing or perhaps a HR21 software or hardware problem?
It's probably a problem with the 21. And I don't think you can fix it. I'd be willing to bet that if you put that external setup you have on another HR it will work. The EADS and the MX-1s are a good setup.
My HR22-100 seems to be working fine.
Why don't you stick the MX-1 with the EADS HDD on the 22. Betcha it works.
