So, now we go to walk with ES charged body holding the HDD in hands. Right ?
I never said anything remotely like that. Quit trying to put words into my mouth.
Pete, nevermind.......I'll just stick to my original comment which is correct: "when swapping drives, beware of static electricity, just as when installing a HDD into a computer". Let's move on.
I'm just try to understand what exactly you did try to pose (not just ESD hazard in general) ...
Anyway, ESD precaution is mandatory when working with electronics.
OK, we've come full-circle. Let's move on.
OK. We done with the off-topic.
Just a followup after a month. HR34-700+AM21N+CalDigitVR. RAID1; Turbo mode.
The storage is rock-solid. Have stressed with 5 record streams and 1 playback and not a single pixelation.
Only wishing HR34 software bugs would get resolved!
Will this work for eSata for HR2x receivers?
That is the TT enclosure most refer to on here...I have several and they work fine.
Rosewill RX-358 U3C BLK (the new one with USB3 & eSATA)
WD AV-GP 1.5TB SATA II (WD15EURS)
SIIG 3.3' SATA External Cable (CB-Sa0111-S-1)
It has been reported that this new Rosewill enclosure will not work with the HR22 and that is NOT correct. It doesn't work with the enclosed eSATA cable but works just fine with the good cable from SIIG. Enclosure and drive are cool and dead silent even with the cooling fan on. Stable in daily use for 5+ weeks now. No bobbles. Nice to have all that space with football season coming on!
Just wanted to point out in a large study reported a year or two ago hard drive failures are more likely the cooler the drive is.
In other words hot drives fail less often. So don't waste time worrying about keeping your drive cool.
I don't recall where I read this, perhaps it was the Communications of the ACM, but it should be easy enough to find.
I know it seems counter-intuitive, but working in IT for 30 years I've seen plenty of surprising results like this. Typically upon closer inspection, they do make sense.
For instance LinkedIn tried to replace a bank of 10,000 rpm SCSI drives with SSD's only to find performance dropped. They found the problem and were able to fix it, but it is not at all surprising once you understand the details. That article is in an engineering blog on their site.
You probably should try to find a link to those findings. You're gonna get arguments about this. I have to say that my experience with HDDs is limited to DVRs and, to a lesser extent, computers, but my experiences with the HRs would support you. As long as the HR doesn't get too hot and shuts itself down (has never happened to me with an HR, got it with a TiVo that I shut the fan off to see what would happen) I don't see any reason to worry about the HDD overheating.
It's good to see your first post after 3 years here ... But, such "link" doesn't have anything good to discuss. While you are is not primary source of the research.
No temp range, what should come with such quick reference.
And you probably didn't get a grasp of big difference of DVR environment and server room.
In short: DVR is running on high end of working temp scale 24/7 because of bad airflow design, perhaps came from very basic engineering experience, low budget, good intention to reduce a noise, etc. Plus there is no way it would be too cool - it always would be +10..30 degree higher then room temp. Living room - not a server room where you wear warm cloth while working inside.
Novice here, want to build one for DirecTV HR24.
Have a coupon for Staples. Will this work:
Western Digital Caviar Green 1.5TB SATA Desktop Hard Drive
Item: 918224 Model: WDBAAY0015HNC
Should work. That model # is for a differently packaged HDD than the usual specific models we recommend, but a Green Caviar HDD should work with any of the HRs. You won't know which model it is until you buy it and open the box. The 1.5TB models are a much better choice than the 1TB models.
Just checked Amazon, that model is really expensive for a 32MB cache HDD. You can get a 2TB HDD for less than that. With a 64MB cache.
Saw prices close to $160 on Amazon. That's really expensive. You can get the HDDs at cheaper prices on Amazon or NewEgg. But, if the coupon you have is worth ~ $50, it's not a bad deal.
Search the model number, I'm seeing them for $101 to $104 on Amazon.
Yeah, I just saw that one. The rest are around $160. No telling what you're gonna find on Amazon. I searched: Internal drives +WDBAAY0015HNC
Staples price-matched, so I got it for $84.50 with my coupon and after tax.
Now shopping for a case.
Looking at the Rosewill RX-358 U3C SLV Aluminum / Plastic 3.5" Silver USB3.0 & eSATA External Enclosure
Will I need a better cable to connect to my HR-24?
I've got several Rosewill RX-358 eSata boxes (both USB 2 and USB 3). The enclosed cables have been fine. As a side note, it seems that Weaknees has used these same Rosewill enclosures (at least they look identical). They have worked perfectly for me with DirecTV DVRs and with my PCs.
An additional data point of a working setup:
Western Digital 1 TB WD10EURX ($97)
Vantec NexStar CX NST-300SU-BK ($23)
BTW, the HR24 replaced our working but 6 year old HR20 and DirecTV did not ask for the HR20 back.
