[gentoo-user] Hard drive RPMs and data speed.
Howdy, I'm wanting to get a hard drive that is pretty good size. I'm looking for about 1 to 2TBs or so. Thing is, a lot of them seem to be 5900 or even 5400 rpm drives. I realize that the data on there is packed pretty tight so I want to ask a few people that may have one or more of these things a few questions. Are they as fast as a slower RPM drive? Would they be fast enough to play HD videos and such? I have quite a few 1080 HD videos. I don't want the drive to cause issues. For additional info, I put my videos on their own drive. I have a 750Gb drive that is mounted on /data and videos are placed in there. When I am playing a video, the only thing being accessed on that drive is the video. My OS, /home partition and such is on a separate drive. The drives are also SATA 3Gbs/sec drives. My mobo doesn't have SATA 6Gbs/sec. Can someone that has one or more of these post their hdparm -Tt results? Different speeds would be great too. I'd like to compare what a 5400rpm drive would do compared to a 7200rpm drive. Thoughts and info please. Dale :-) :-)

I assume you meant to say as fast as a faster RPM drive. No, of course not. If we're speaking about the same capacity and amount of platters, of course. If we're not, then yes, they can be as fast because of the higher data density. Would they be fast enough to play HD videos and such? I have quite a few 1080 HD videos. I don't want the drive to cause issues. The transfer speed required for playing HD videos is virtually zero. 1080p video compressed using an 8mbps rate require 2MB/s. This can be done even with the slowest drive from 10 years ago. Today's slowest drive are able to play about 40 or 50 of those HD video simultaneously. So the answer is yes. They can play HD video :-) Most of those 5900/5400 disks are meant for pure data storage. The lower RPM is used to market them as green and silent, meaning they don't consume much power and aren't noisy. Installing your OS on them though isn't going to give you good speed. They have good transfer rates, but their access times usually suck. Can someone that has one or more of these post their hdparm -Tt results? Different speeds would be great too. I'd like to compare what a 5400rpm drive would do compared to a 7200rpm drive. Simply Google around for benchmarks of the drivers you're interested in. Note that is in area where it doesn't make any real difference that the benches or reviews you find are performed under MS Windows. The results are applicable to every OS. As a rule of thumb when buying drives: if you want to install software on it, buy an 7200RPM drive with good access times. Of course they're more expensive If you just want to store all your downloaded HD porn and music collection on it, a silent 5400RPM drive is a good choice. Oh, and one other thing; hdparm is only meant to get you the continuous I/O transfer rate. It's an awful benchmark for anything else, like what happens if a file is fragmented or how fast it can copy/write data spread around the disk, how good it is at combined random I/O operation, etc.

[gentoo-user] Mythtv problems 2.0: carter
OK. My recent Myth problems were on camille, which thankfully is now working. Originally, I was trying to move my Myth installation to carter, which is a dedicated linux box. I wanted to do this so that I could dual boot into Windows XP on camille more often. I've been applying all the advice I've been getting to carter's installation and everything works except for Watch TV. Carter's TV card is Hauppage HVR-1950 (pvrusb2). I can get video with it (I have the /eev/vieo0 device node and I can get a file by mplayer /dev/video0). I'm thinking the card type in Capture Cards in mythtv-setup might be the problem.

I know, that benchmarking is anything but science...but on the other hand: Knowing that a PDP-8 (which was newer than the PDP-7 on which Dennis Ritchie and Ken Thompson started to develop UNIX) had about 0.004 MWIPS and a current desktop PC has something like 3500 MWIPS let shine a total different, more brighter light to terms like computer pioneers... :) Those days a 'bit' was more a real thing than nowadays :))) Back in 'those days', cycle-counting is a must for all programmers. Heck, as recent as 8088, programmers still do cycle-counting (especially assembly programmers). Kids these days have it sooo much easier. Oh, and... get off my lawn! :-D Rgds, One of my colleagues at the lab still tells stories of the time when he set up a radio receiver in the canteen so he could hear the mainframe buzz on shortwave radio while his program was running. When the sound suddenly changed, he knew there was an error. Regards, Florian Philipp Hi, oh YEAH! This is true computer magick! Really! Somehow I miss that day, when little green bit from outer space were little green bits from outer space, and real programmers has gone where no man has been gone before! I started with an Atari 800. I had a bible called Mapping the Atari which had described EVERY used memory cell with its funtion and what you can do with it. Peek and Poke was daily business, and GOTO was crime at all. Damn, one knows the function of nearly every chip in this computer and it was possible even to write assembly programs (it was the assembly code of the graphics chip! NOT the CPU!) of the which get executed \ each vertical blank interrupt! Somehow sad, that this time has gone. (Am I getting older?) Best regards, mcc

I can get video with it (I have the /eev/vieo0 device node and I can get a file by mplayer /dev/video0). I'm thinking the card type in Capture Cards in mythtv-setup might be the problem. Here is the output from mythbackend: SNIP I'm using the recommended IVTV MPEG-2 Encoder card type. What am I doing wrong here? 1) I don't presume to know why you need to dual boot but unless you're playing games or something that requires better graphics why not run a Windows VM and not reboot at all?

I got this one about 2 years or so ago. I did have random lockups a
while back but I think it was a file system error. I moved everything
off the drive, reformatted it and it has worked fine ever since. If I
get me a new drive, the one above will be a backup sort of thing.
I seem to have good luck with WD and Maxtor myself. Like you said tho,
everyone has their horror story. It is bad that they didn't give some
sort of explanation on the second failure. I have noticed that some
things, car parts for example, have what they call a limited
warranty. That means exchange once and then you are on your own if it
fails. Maybe they are doing that with their drives. That would explain
a lot too.

[gentoo-user] the same hard-drives, different number of sectors...
Hi, perhaps someone could explain this to me: I have bouth two the same hard-drives. The same model (Hitachi HUA722050CLA330), the same firmware (JP20A3EA), the same size (500GB). Well, not exactly. Both hdparm and fdisk report different number of sectors (976771055 versus 976773168). Although not a big difference, yet I expected them to be exactly the same (want to use them for raid1). So how is it possible they do not have the same number of sectors? I have bought them from one supplier, even their serial numbers are very close (only the last 2 characters out of 24 are different)...

My point is that the numbers aren't what mattered here. My point is that SAMSUNG sold me a shoddy product, replaced it with another instance of the the same shoddy product, wouldn't replace it again, and never addressed a detailed technical report of a systemic problem in the same. Bad tech, bad customer service, and it looked like this was a more common scenario than among other manufacturers. All of it boiled down to a nasty case of being a bad candidate for spending time and money. Did IBM refuse to replace your failing drives? Did you include detailed technical information that should have allowed them to resolve issues leading to those drives' failures? For me, SAMSUNG's behavior in the customer service department indicated that I wasn't likely to get good service in the future, and the rapidly-failing drives (combined with my analysis of the SMART output and the history of SMART problems with SAMSUNG drives) indicated to me that I'd need to use that customer service department in the future if I bought more of their drives. So you've got six working drives, and a drive that works now that you patched the firmware. Congrats on choosing a model for which a firmware patch was made available (unless that was just luck...). Also, good luck if you have a failing drive that was sent to you by RMA. It's been a few years; if you're lucky, they may have cleaned up their act. -- :wq
[gentoo-user] DVD-mp4 - handbrake vs something else
I'm getting a Kindle Fire in a few days. While I didn't get it
specifically to watch movies looking at the specs it does apparently
handle mp4 as a video format and they state online that you can watch
streaming movies TV shows from Amazon's servers. I do a lot of blood
donations - roughly 20-25 times/year - that take 2-3 hours each so
either being able to read or watch a movie would be a pleasant way to
pass the time. Being able to hold it comfortably in one hand is
important to me.
I started looking around in Google for something to encode a few DVDs
so that I could see how well it works. A program called handbrake was
showing up in a lot of links, but it requires an overlay. While I have
no problem adding yet another overlay (which on is best?) I wondered
what might be in the normal portage database that others here use for
this purpose?
Thanks,
Mark

A program called handbrake was showing up in a lot of links, but it requires an overlay. I've been using handbrake for about a year, and it's _very_ convenient. It has presets for many popular devices. If it knows about your device, it's going to be hard to beat handbrake. [Best of all, you don't have to put up with some horrible GUI to use it.] I have a 4th gen iPod touch, and handbrake knows the right settings to use for that device, so it's a toddle to use.
