O.T. Dell 780 Problem

I remember the HDTune now. I downloaded and tried it on the 8500 just to test it out before I get the new HD's. http://i64.tinypic.com/34xj2tc.jpg http://i65.tinypic.com/2mxpjqp.jpg http://i66.tinypic.com/b7i9uo.jpg http://i64.tinypic.com/2hnaypi.jpg http://i65.tinypic.com/5bpv7r.jpg Robert The transfer rate curve, the first picture, almost looks like the OS isn't idle while the benchmark was running. The drive appears to have bad table manners, in that the load cycle count is 49769. That means when the drive is idle, it's parking the heads. It looks like it's parking the heads every 20 minutes or so, which all things considered, isn't bad. The really kooky drives can do it in a shorter timeframe than that. I took a look at my two "park-er" drives here, and their ratio is about the same as yours. Your Reallocated is still "0", so that's good. I would be a bit concerned, if the transfer rate curve really looked like that. If it did actually look like that, the symptoms would be inconsistent. You have a lot of spikes in the transfer curve, and if those were really there, your Reallocated should start to show problems too. My experience is, if all the bad parts of the disk are concentrated in one area, it's possible to have a "gouge" in the transfer curve, yet with reallocated still being in fine shape. You have a decent number of hours on the drive. My champion drive (one that doesn't park the heads), has close to 40000 hours on it now. But it's probably the exception here. And one at work, a ball bearing drive, it lasted 60000 hours (and was still working when it went off to the landfill). You had to turn it on its side, until it had spun up, but once it was spinning, you could return it to horizontal, and it would keep running. ******* If a drive begins to "feel slow" and there's a wide gouge in the transfer curve in HDTune, then you could consider replacing it. As long as you have backups of that drive, I don't really see a reason to panic just yet. Reallocated is still 0. And the spikes aren't concentrated enough yet, to cause it to feel slow. I have a lot of trouble in Windows 10, running HDTune, because the OS likes to start doing stuff, as soon as I try to run a benchmark. Windows 7 has some of those behaviors (Windows Update could start scanning), but overall, Win7 isn't quite as bad as Win10, at ruining benchmark runs. The best OS I had for benchmarks, was Win2K. It didn't interfere with what I was doing. Paul |

Well I the OS wasn't idle when I did the test,..
I didn't think about that,... Maybe I should do another with it at idle. Robert |

The best you can do is run HDTune multiple times, and see if the "spikes" (if that's the right word for something that goes downwards!) are in the same place across the disc. If you get spikes in different places, then they're just due to the OS interrupting; if they're always in the same part of the scan, then there's probably a dud patch there, that is being swapped for a good patch, which impacts the speed. If they have breadth, that's not good. If there haven't been enough for the reallocated sector count to start showing other than zero (the manufacturers don't show above zero there until it gets above some threshold; _all_ drives have _some_ dud sectors, even from new), then you've _probably_ got time to image or otherwise copy data from the drive. HDTune is a moderate way of seeing if you have dud sectors that aren't enough for the reallocated sector count to start showing; if only a few, the drive may be fine. -- J. P. Gilliver.

I was active on the computer on the
previous test and this time I had nothing open besides HDTune. http://i66.tinypic.com/nbzn79.jpg http://i64.tinypic.com/2cihf5s.jpg http://i67.tinypic.com/2vcz7mq.jpg http://i64.tinypic.com/2zs4s9s.jpg http://i63.tinypic.com/eqcrom.jpg Robert |

The drive doesn't look "brand new", but it also has 17,000 hours on it. No reason to panic quite yet. Keep doing backups. ******* The other four curves should not depend on user activity. It's only the benchmark curve that's quite affected by both user activity, and how the OS is designed. Paul |

I decided to run HDTune on the 780
and the first scan shows allot of spikes! I ran the scan several times after which usually showed something similar to the second scan results. http://i67.tinypic.com/2h5s26w.jpg http://i65.tinypic.com/svtpns.jpg So what caused the spiking? I did accidentally touch the keyboard once during testing. Could that be it? Thoughts/suggestions? Robert |

Something is interfering with the first scan, but what ? The second scan is slightly weird, in that there is a sprinkling of seek dots, outside the band. I've seen this before in some pictures, but again, I can't offer a rational interpretation. Some people have drives which are apparently healthy, and the drive does that. Overall, the second curve is OK. Maybe you have an AV doing some scanning in the first picture ? It could be Windows Update. Which will eventually settle down. Paul |

I ran another HDTune to check the hours
on the 780. Here's the 8500 scan: http://i66.tinypic.com/nbzn79.jpg http://i64.tinypic.com/2cihf5s.jpg http://i67.tinypic.com/2vcz7mq.jpg http://i64.tinypic.com/2zs4s9s.jpg Here's the 780: http://i63.tinypic.com/qqpstj.jpg http://i65.tinypic.com/123mp8g.jpg http://i63.tinypic.com/11kb8gj.jpg I see what you mean about the seek dots,.. Why is it different; with 3 partitions on the 8500 and only 2 on the 780? I tried clicking the cubes on the info tab but no response and no information at all on the health tab. Shouldn't it at least show basic information like how many hours? I ran error scan tab and it came back all green. Thoughts, suggestions? Robert Will the new HD's be like that? |

Shouldn't it at least show basic information like how many hours? I ran error scan tab and it came back all green. Thoughts, suggestions? Robert Will the new HD's be like that? I can't tell if the Hitachi is on a USB cable, or is connected to a SATA or IDE internal cable. USB doesn't usually have passthrough for SMART, so the window should remain blank. However, your Info page for the Hitachi is populated, even if all the tick boxes are ticked, so I can't really be sure why SMART has gone missing. While it's possible for SMART to not be implemented on a drive, the Hitachi has design roots from IBM research, and I think they played a leading role in SMART. SMART should really be there. The other bit of weirdness, is HDTune lists a temperature for the Hitachi, and that would be obtained via SMART. Temperature is carried in the SMART table. I have had SMART "freak out" on Windows 10, but that was Microsoft screwing around, and they fixed that. It's working again. My guess is that the Hitachi is a "weird-nick". That's what the evidence says. There's enough evidence there to say it should have worked, yet it didn't work and the table stayed blank. The Seagate DM003 is still safe to use, provided you continue to make backups. ******* I have probably a couple dozen drives here, and I think all of them have a SMART screen :-) There is one drive that won't have one, but that's my 4GB IDE drive from the year 1999 or so. That may predate SMART. And I have drives that are older than that, that haven't been powered up in probably 30 years (and are likely to be frozen via "stiction"). One of those was 250MB in size (i.e. "huge"). And the heads don't have a ramp to retract onto, and the heads land on the platter (that is bad for the heads). One of the companies did a research project in the lab, where they allow the platter to spin, and they let the heads rest on the platter. It takes a whole 30 days, to grind the heads off :-) The reason they're doing experiments like that, is planning for the day when heads no longer "fly". I don't want to buy any of those drives!

I had nothing attached to the Hitachi when
running the HDTune tests. As you say since it showed the temp it should also show the SMART but doesn't. Robert |

Question: at some point I may need to
replace the 750 GB HD in the 780. So is there a conflict of putting a 2TB HD in the 780 and using the Mrimg when it was a 750 GB HD ? Just curious,. can you have two operating systems on the same HD? One for the 8500 and one for the 780? So that it could be used by either computer? Thanks, Robert |

Thanks, Robert If you changed from a 750GB to a 2TB 1) Restores still work. 2) The backup definition still works, because it's based on partitions as far as I know. If a partition changed size, it would probably still back it up. 3) What I can't tell you, is how "identifier sensitive" it is. Does it use the disk serial number ? There are a number of identifiers that "don't matter", but then there will be one or two identifiers that do matter. I haven't tested whether a backup definition is insensitive in that way. It certainly won't take you long to define another regularly schedule or on-demand backup if you want. It might even be possible to edit the definition of an existing one. I would class this as "a problem you could deal with". ******* Now, your second question is one I've never tried before. And basically, your question amounts to "how tolerant is the boot loader to hardware changes". Windows To Go, is the only mode of OS installation I know of, that demonstrates a boot loader can tolerate life on two different machines. But I don't know if that implies that this will also work for you. https://en.wikipedia.org/wiki/Windows_to_go "When using a PC as a host, only hardware certified for use with either Windows 7 or Windows 8 will work well with Windows To Go." Certainly, if the 8500 OS "comes up" on the 780 hardware, the activation logic is going to detect that. But since this is Windows 7, the Royalty OEM OS activation is SLIC based, both machines give the "I'm a Dell" secret handshake, and in fact the activation logic is supposed to tolerate that. But this is a whole area where I have no experience, and you'll be in "blue sky" country, "experimenters paradise", when you try it :-) It doesn't have to be hard to do, either. You could clone over a second OS partition, then use EasyBCD to add the second OS to the boot menu. No OS re-installation should be necessary. You'll never lack for a hobby... :-) Paul |

I was just thinking of the new HD's... for the present
because of finances I'll only buy (1) this time around and re-use the Star-Tech case. Didn't we make the present 780 2TB external backup HD boot to the 780? When I get the other HD's we need to make another spare 2TB HD for the 780 and 8500. This all came about from our talk of replacement computers and how they all have Windows 10, even the refurbished computers have it and I want to stay with Windows 7 Professional. I figured the second question was blue sky country *L* It would be interesting to try it out and see what happens. My thought was to have a interchangeable drive for the 8500/780, if possible.
