External Hard Drive on a 722 receiver

[R0ss]

I know for a fact that the EHD I am using must use external power supply. I inadvertantly unplugged it and was totally freaking that it had died. Yes I have had it plugged into both a powered hub and the 722.
This discusion leads me to believe that the recent issues I had adding the sling adapter may be related to the 722' s power supply. I would bet that when the final specs were done they cut back on the power supply to save a buck. Of course the money folks didn't think that in a couple of years we would be overtaxing the unit with multiple usb devices.
Just a thougjt

..... Did I say "probably" enough here? ....

Probably.

.... But having spent many odd minutes myself, I don't remember anyone trying and failing, either. Have you?

Not certain, but I believe someone way back tried and failed. Could be wrong.

And, the movie ends...not good for the USB powered drive.

Well... Not really. DISH's description was rather vague and misleading. They actually mean it needs to be a single drive, not a RAID 0 (or 5 or 10) array, though I think I have seen people getting RAID 1 arrays working as EHDs......

I have a RAID 1 working. It's done in hardware on my unit, so it's invisible to Dish. I suspect 10 would work too, so long as it's all done in hardware. And I also suspect a RAID 5 (really don't like the 5s) would work too, if done 100% in hardware, but that would really be something for the Department of Redundancy Department.

To all the naysayers here. I just checked each of my 722 USB output with a resistive load of 0.5A and the 5V output didn't budge. BTW, my external USB exhaust fan draws 0.35A.

Since the additional load is external, any 722 internal temperature rise should be very minimal ~1%. (This is for all the "smart" guys here, before they jump on me. 2.5W @ min. 80% efficiency = 0.5W which is ~1% of the total 722 power consumption).

Just to make it very clear, I am NOT advocating or endorsing ANYTHING!

And your point is?????

OK, now let me turn this around. Until you actually attach a USB non powered EHD to your receiver, get it to format and are able to store programs on it, you haven't said s**t... That's a fact!

No it does not! The statement below is ambiguous on many levels.

I know for a fact that the EHD I am using must use external power supply. I inadvertantly unplugged it and was totally freaking that it had died. Yes I have had it plugged into both a powered hub and the 722.

Ross didn't tell us what type of drive nor what current draw it has. In the first place, if this is a traditional powered 3.5" enclosure, it will most certainly disappear when unplugged from it's own power supply. I do this all the time and did this many times to a 612 using the power switch on a Fantom Greendrive enclosure. At the time it had a WD Caviar Blue which annoyingly NEVER spins down when not in use. Obviously not a "green" drive at all.

And the part (above) about having "it" plugged into a powered hub did not say whether the enclosure was also powered independently at the same time, nor whether it worked ok if powered solely off the hub.

Lots of possibilities, not the least of which is a very "sucky" 2.5" USB-powered drive.

I am sorry of o wasn't clear. The point was no matter how it is plugged ib, powered usb hub or directly to receiver, the external power supply has to be pluggwd in for tge drive to work.
I was jusstating my experience. I suppose if a person haa ths resources and time a drive might be found that will work without external power, who knows.

Thank you for this clarification.

That is very interesting; if it's a 2.5" bus-powered drive, it's behaving just like a 3.5" external. Was it (formerly) operable on a PC with just the USB power alone? I'd be interested in the make/model.

I bought the drive specifically to use with my 722. As soon as I can set my grandson down I will go and look at the drive and get you the model and manufacture. Just to be clear it has never been attached to a pc. I cannot read the little teeny tiny print with the model number but it is a western digital hard drive it is 3.5", can see drive through vents.
Again I just wanted to state my experience if no other reason than to lend support to those that can articulate the technical reasons why, in general, the EHD should have an external power supply.
I agree that thw OP should jist connect up a drive, without external power, format and copy to it, then watch a program. If it works post the details. Why argue with folks?

Thanks again. I've never met a 3.5" drive that could be powered off a USB 5V bus. Most require 12V and a whole lot more power than a single USB port can source. Notebook 2.5" drives, on the other hand, are often bus-powered. I had a look at the Western Digital Scorpio Blue drive specs, and virtually all of them are sitting right at the limit of 0.5 amp during read/write. Except their newest 1TB drive (model WD10JPVT) that sucks only 1.4W during read/write. I predict this model will work.

In my mind the requirments that Dish posted on the web r for general consumption. Withe advances in technology most folks expect things to just work. It would create a lot of unnecessary support calls if they gave a choice.

Yeah I have a minor problem. I recently purchased this 2TB Western Digital External Hard Drive.

Sometimes, when I turn on my external hard drive, the 722K doesn't recognize it so I have to remove and plug in the USB cord again to the DVR in order to get it to recognize the external hard drive.

Is there an easier way to get the 722K to recognize the EHD?

Mot sure why you r having this problem. There r two usb ports on the 722k. I would suggest switching usb ports. If this solves the problem you may have a bad usb port. Another thought would be to unplug the drive from the receiver, unplug the receiver wait 30 seconds and plug back in. Once it reboots plug on your drive. Also be sure u use the external power.
Good luck

That happens to me with my 1TB WD EHD along with 3 other EHDs. Happens on both of my 722Ks. No idea of a solution. Works fine once it's recognized though, and never disconnects (except once the WD somehow disconnected while in sleep mode, but hasn't happened again since.) As long as they don't disconnect once they're recognized, I'm not too worried about it.

 

[TheKrell]

I would like to report success with a bus-powered EHD on one of my 612s. I put a Crucial 250GB SSD into a $6 enclosure I bought at Microcenter. It has been working fine for days. I moved HOURS of recordings onto it, and back. Played some directly, too.

 

[revick]

What's a good EHD to use?
I am considering using a WD Elements 2tb EHD. I have heard that Dish raised the allowable amount to 2 tb. Anyone use this EHD and what were the resu?

Yeah, makes sense. As far as the receiver/computer is concerned, it looks just like any other standard USB mass storage device. Software RAID or RAID that requires a RAID controller in the receiver/computer is what the DISH receivers don't support.

 

[harshness]

What's a good EHD to use?

One that meets the specifications.

For those who can't read the web page on the DISH Network website, those are:

External Hard Drive Requirements

Dedicated power supply
USB 2.0 support
Single-platter drive, no flash memory

I highly recommend avoiding mechanisms that don't originate from recognized hard drive manufacturers (unless you get a really bitchin' deal).
