  • Strange problem with Maxtor UDMA66 HD

    Hi

    I have a Maxtor 13g UDMA 66 HD and a Seagate 9g UDMA 33 HD. I got the system a few months ago and I used the Sandra System Benchmark utility for the harddrives. The performance was decent a few months ago (except for the lousy milsec rating for the maxtor 68ms vs seagate 8ms), but as of the last week, my Maxtor is getting crappy (drive index) results and the Seagate is improving. Both HDs are about 25% full, and I have done nothing silly with adjustments.

    I got the following results (2 mos ago):

    Maxtor Seagate

    Drive Index# 8915 7781


    Buf Read 157 MB/s 149
    Seq 13 10
    Rndm 877 kB/s 4
    Buf Write 175 MB 6
    Seq 15 MB 9
    Rndm 8 MB 5
    Acer access time 68 ms 8 ms


    As of last week:

    Maxtor Seagate

    Drive Index# 6079 8970


    Buf Read 146 MB/s 167
    Seq 9 10
    Rndm 877 kB/s 4
    Buf Write 175 MB 6
    Seq 12 MB 9
    Rndm 6 MB 5
    Acer access time 76 ms 9 ms

    So, I would like to know if anyone can suggest why, and how to fix, my deteriorating drive index on the Maxtor? As I said, it is only a few months old, and I believe I am using optimizer cache program with the HD write behind enabled. DMA is checked on the Seagate, and as you know the Maxtor being UDMA 66 has no DMA.

    thanks

    Since when does a UDMA66 drive not support DMA transfers? It should be downward compatible to UDMA33 though. I'm missing something here.

      He has an UDMA66 controller built into his BE6, which has DMA always on (can't disable).

      I think this is a twofold problem.

      1.) Maxtor sucks hardcore. Sorry, they just do. There's a reason they're the cheapest available drive.

      2.) Your drive optimizer program is flaking on you. Any caching program will totally screw up results from a benchmark. Try it with the optimizer disabled and let us know the results.

        1. Maxtor drives do not "suck". If you want proof go to www.storagereview.com
        2. Second never used a Hard drive speeder up kind of utility because they don't do anything.
        3. Get a real benchmark program like HDTACH from http://www.tcdlabs.com/

          Maxtor (oh my GOD, I wrote Matrox by mistake. I hope the acolyte isn't here... good, now it's gone!) hard drives SUCK. They SUCK REAL BAD. I'm serious. I have used, abused, and sold all brands of hard drives. No other drive, on a regular basis, is returned making a loud "snap, snap, snap, snap" noise.

          Not only that, but their throughput is sub-par, they are loud, and did I mention that they are prone to breaking in a rather spectacular manner?

          Secondly, yes I agree - no "hard drive optimizers". Funny that your DRIVERS will do that if you use them correctly.

          *sigh* Ok, rant off.

            I've got a Maxtor DiamondMax Plus 5120 7200 RPM UDMA/66 10gig drive, and have been pleased with it. Well, except for the before mentioned HORRIBLE, frightening, make you think the computer's about to explode clicking/snapping noise that's occurred a couple of times since we've had it. That and HDTach shows that it won't hit above 22MB/s burst transfer rate, but I think that's probably just my crummy Epox MVP3G5 mobo.

              Jon,

              Get your data off that hard drive. NOW. TODAY. Get it all off and return it immediately for repair/replacement. That clicking will recur, and happen more and more until the drive expires!

              I mean it. Heed my warning.

                Great... :-) It's probably a good thing then that we keep what little important stuff we have backed up on zip disks. Thanks for the warning!

                  Jon,

                  No thanks necessary, just get yourself a working hard drive, that's all the thanks I need.

                  Here's how to go about it:

                  Case 1: You bought your drive recently (within 30 days) from a major store (Micro Center, CompUSA, Circuit Shitty).

                  Path of Action: Go to store. Tell them the drive sucks ass. Make them give you a new one.

                  Case 2: You bought your drive from a smaller computer custom shop within a year (standard warranty time period for those kinds of shops).

                  Path of Action: Same as before, only you have longer!

                  Case 3: You are out of store warranty (30 days for major chain, 1 year for small store).

                  Path of Action: Go to Maxtor's web site. If they have an online RMA form, fill it out. If not, just call their technical support number. These people will want to "do some tests". Tell them you aren't interested in tests because the drive made a HORRIBLE noise (try to make the noise on the phone with your mouth and throat, that always works - they're too shocked to argue with you at that point). They will issue you an RMA number.

                  NOW is the tricky part. Demand a rapid exchange, or a cross shipment, or whatever Maxtor calls it. That's when they ship you a new drive overnight (or priority, whatever), and you send the old one back within a couple weeks of getting the new one. Gives you time to do a drivecopy or ghost to get your data backed up. You just have to give them a credit card number so they can be sure you don't skip town with their drive.

                  Hope this helps!

                    Hey thanks a lot for the suggestion for turning off the disk optimization, it really made a HUGE difference in speeding up the system!

                    But there is still a bit of irritating weirdness. When I run HardDrive Tach on my Maxtor UDMA66 (91366U4) 7200rpm, I get the following specs:

                    Rand Access Time 16.9ms
                    Read Burst Speed 59mbs

                    BUT

                    when I run the test on the older Seagate UDMA33 7200 rpm

                    Rand Access Time 13.3ms
                    Read Burst Speed 14.4 mbs

                    I know that the Burst speed is better on the Maxtor, which it should be, why the heck am I getting a slower Access Time than the older Seagate? I have turned off all the disk optimizer, so what gives? And I read somewhere that the Maxtor should get under 9ms rand access time...any thoughts?

                    thank you again

                    ps should I enable write behind caching in the file system properties??

                      Ok, I'll say this slowly, maybe you'll hear this time...

                      M A X T O R S U C K S.

                      It's that simple. They can ADVERTISE a 9ms access time, but in practice my IBM 7200RPM U66's seldom get much better than 9ms... Seagate Cheetahs still are only 8ms (except the hyper-ultra-mega-fast ones that cost as much as my last car!). Nothing Maxtor has ever made has been better than 10-ish ms, no matter what they advertise.

                        I'll take Gurm's warnings into account, but I've never had any clicking sounds out of my Maxtor 10gig. 12.9ms random access, but only 21.5 mps read bursts. But this is because of the same Epox MVP3G5 as Jon. I wouldn't call it a POS, but the burst speed is not what it should be on these boards.

                          Maybe POS is a little harsh on Epox. :-) I just wish VIA or the board manufactures would just admit that either there's a driver or hardware problem with these motherboards that is preventing full UDMA/66 speeds.

                          I'm kinda wondering if perhaps the UDMA/66 support is similar to the early G400's AGP 4x support, in that they really mean it just works with a UDMA/66 drive, but won't really run at the full speed.

                          Oh, about the G400, if I were to switch my G200 for one, would it improve performance much? With Halflife, my G200 almost functions as a 3D DEcelerator, and I get much better framerates in software mode in complex scenes. It runs quite good with Quake2 though.

                            At least twice as fast, if not faster. Yes, the G400 is a major step up.

                              Jon,
                              3dMark99 scores with K6-3 450:

                              G200 2260
                              G400 3750

                              I have both video cards overclocked, but the relative speed is indicative of what you can expect. The G200 is on a 112 mhz FSB, but the G400 is only on a 100 mhz FSB on the Epox MVP3G5. That's another disappointment of the MVP3G5 - it won't overclock the FSB. The G200 is on an MVP3C2 and it easily overclocks the FSB to 112. I'm sure if the FSB were 112 on the G400, it would add 50 points to the 3dMark99 score.

                              RAB

                              Oops! Sorry, I got way off the subject.
