  1. I queried the average seek time I measured for my 2-head 6Y080L0 drive with Maxtor: 13.7ms - 4.2ms (latency) = 9.5ms seek time ? They said: no - 13.7 - 4.2 (latency) - 0.1 (BIOS/driver overhead) - 0.5 (settle time) = 8.9ms :?: Ok, I can understand allowing for the BIOS/driver overhead, although with modern systems I rather doubt that it makes a measurable difference (they actually said <0.1ms, so allow 0.1). But taking of 0.5ms for "settle time" ? This seems a bit odd - using this formula would give a 7.8ms seek time for the 3-head 6Y080L0. Surely the "settling" is part of the "seek" ?

    access time => seek time ?

    Of course, the fact that they have changed the seek spec. on the website and datasheet from <9ms to <=9.4ms is purely co-incidental :wink:

    I guess it must be either the pwer supply or more likely the molex connector/wires that you are using to connect the drive. How about trying a different molex drive power cable ?

    Green LEDs ? Are you sure that the power button is set up to power-off or go to suspend. Normally when powered off there are no LEDs on, but when in suspend (S1) the power LED is still on. However, I used to have a motherboard (Soyo) that had an LED on it that showed it was connected to power ever when in the off state. The point of this was to warn users not to plug/unplug anything unless the system was unplugged at the wall socket. When an ATX system is "off" the PCI and AGP slots are still powered for example (so that cards can wake the system).
  5. Have you tried using no sound card ? Does that solve the video glitches ?
  6. :oops: ok, I see it in the review now -sorry :oops:

    You didn't unplug / plug with the power on, did you ?
  8. I've just read this again (to see if it offered any insight into the "correct" way to work out seek time from access time). One thing I noticed was the apparent importance of burst rate, due to the likelyhood of cache hits: In the light of this, it would seem possible the Maxtor ATA drives may benefit from using UDMA-133 as opposed to UDMA-100. Since TB3 only uses UDMA-100 it would seem that these drives are not being allowed to work at their fullest performance. Therefore it seems to me that to make fair comparisons, a UDMA-133 compatible controller should be used. At the least, it would seem a good idea to test a current Maxtor drive (eg. DM+9) again using a UDMA-133 controller, testing both in 133 and 100 modes and seeing if there is a significant difference in any tests. If not... then the current tests are valid, but if the difference is significant then I think the published tests should reflect this. I'm not saying that using UDMA-133 will make much difference; I really don't know. I'm using UDMA-66 for drive :wink:

    It's just bad editing - the previous version of the spec. sheet said

    :roll: you've read the spec. sheet :?: What is it about and that you don't understand ?

    Maxtor 60GB Drive made in the U.S.A ?

    Why not just email Maxtor and ask them where the "made in USA" drive was made ? :roll:
  12. Orca

    Annoyed with Maxtor.

    If your drive has the wrong warranty date when you look at the page on the Maxtor website, contact Maxtor warranty@maxtor.com and they can change the date, they did for me - no problem.

    Eugene: what firmware versions are the different drives using? I see that the seek time is quoted as <=9.4ms - it says that on the website now as well. Previously the website and datasheet said <9ms. My 3-head 6Y080L0 measures 8.3ms, while my 2-head version measures 9.5ms.
  14. See my post here: http://forums.storagereview.net/viewtopic....ighlight=maxtor Doesn't anyone ever use Search before they post a question ? :roll:
  15. I think the only accurate way to find the bus speeds is to find the clock generator chip on your motherboard, then go to the chip manufacturer's website and get the spec. sheet. This will tell you want FSB and PCI speed combinations are available.

    IDE: two devices/channel: why bad performance?

    Ah, I see... I missed this when I read it some time ago: We can easily test our IDE controller hardware to see if it supports the Auto-poll function: I will try it out on the hardware I have access to, only VIA EIDE (571) controllers. Others might like to test Intel and add-in card hardware, just to confirm there is no hardware support. Just to completely clarify this: the answer is hardware support is not absolutely needed, but it is for practical purposes as software-only performance would be poor.

    IDE: two devices/channel: why bad performance?

    Why is controller hardware support needed for "O/Q" ? Reading the ATA-6 spec. this doesn't seem to be the case: please be specific - what exactly is the hardware requirement ?
  19. 48-bit LBA needs software support only, no hardware support is required on the motherboard. It works by sending LBA data to the same port addresses twice - the drive toggles the data internally to assemble the 48-bit address. First 4 bytes are sent to the 4 LBA registers, then the next 4 bytes to the same register addresses (old-style LBA is 28-bit so uses 3 1/2 registers).
  20. Look at the Warranty Status page here: http://extranet2.maxtor.com/servlet/WebAda...tus::WebRequest scroll through the model numbers (remember that the DMax+9 models start 6Y...). You will see multiple model numbers listed for each size: 40GB -> 6Y040L0, 6Y40P0 60GB -> 6Y060L0, 6Y060L04, 6Y060M0, 6Y060P0 80GB -> 6Y080L0, 6Y080L04, 6Y080L2, 6Y080L3, 6Y080M0, 6Y080P0 120GB -> 6Y120L0, 6Y120L3, 6Y120L4, 6Y120M0, 6Y120P0 160GB -> 6Y160L0, 6Y160L4, 6Y160L6, 6Y160M0, 6Y160P0 180GB -> 6Y180L0, 6Y180M0, 6Y180P0 200GB -> 6Y200L0, 6Y200L5, 6Y200L6, 6Y200M0, 6Y200P0 250GB -> 6Y250L0, 6Y250L6, 6Y250M0, 6Y250P0 Now the P0 models are the 8MB cache ones and the P0 models are the SATA ones, but look at the Lx models... L0 = you could have either of the specifications for that drive size; they're not telling (except maybe the serial number gives it away). Perhaps they are going to label them properly soon, actually giving the head count in the model name. What it does confirm, for any who still doubt it, is the use of different platter densities: 80GB with 3 heads/2 platters (60GB each) or 2 heads/1 platter (80GB) 120GB with 4 heads/2 platters (60GB ) or 3 heads/2 platter (80GB) 160GB with 6 heads/3 platters (60GB) or 4 heads/2 platters (80GB) 180GB ... not specified 200GB with 6 heads/3 platters (66GB) or 5 heads/3 platters (80 GB) 250GB got to be 6 heads/3 platters (80GB) I'm not sure about the L04 models in 60GB and 80GB... surely these aren't using 40GB platters? Generally it's very disappointing, isn't it ? At least they might come clean about this issue now.

    SMART Attributes

    SMART attribute values are "vendor specific" and the drive manufacturers don't publish them. However, some people who have made SMART apps. seem to have got hold of some of the meanings. I would suggest that you contact the writers of other apps. like SMARTmon SMARTview etc. It's worth remembering that the attribute values change in vendor specific ways, so the only real meaning to be gained is whether they exceed the threshold or not.
  22. :?: sarcasm :?: Unfortunately, you may find it difficult to exchange your drive like I have. In my case I had specifically asked Maxtor about the specifications before I bought the drive. Still, it may be worth a try (assuming the results are worthwhile). The important thing to note is that I quoted all the published information on their website that specifically says the drives use 80GB platters.
  23. I have just received my 2-head 6Y080L0 drive sent to me by Maxtor to replace the 3-head version... this therefore has one 80GB platter. I hope to post benchmarks for both versions later this week. Note: date: 31st December 2002 serial: Y2T...

    Kazaa Lite?

    Is there any point in getting the Kazaalite 2.0.2 upgrade, (I haven't bothered).
