SATA serial hard drive troubleshooting FAQ



  Because SATA hard disk with a faster transfer speeds, better caching, easier to install and more affordable prices, more and more users attention gradually replace PATA hard to become the market mainstream products.Most believe in a friend''s computer has been used for serial SATA hard disk.SATA hard drive serial port and parallel port compared to PATA hard disk, although with a lot of advantages, but compared to a lot of set plays PATA hard to be trouble, I believe many of my friends have used a variety of problems encountered.With further establish SATAII interface standard, SATA II hard drives eventually become the first choice to buy friends.Compared with the SATA, SATA II has a higher transmission speed hard drives and NCQ function.Many friends in the use of SATAII hard disks are not normally open NCQ transmission speed and 300MB / s, and some can not be used even more SATAII hard disk, then I will use a few problems often encountered SATAII hard to do to sum up:

  First, the motherboard and hard drive support 300MB / S transfer rate and NCQ technology, how to turn them on and get them working condition.

  For now, only INTEL and NF4 chipset driver can know the working status of both.INTEL chipset, BIOS as long as the choice of AHCI / RAID mode, and installed IAARAID disk drivers, this driver can be informed by the work of state.

  And NF4 motherboard chipset, BIOS, there may be 3Gb / s and 1.5bGb / S mode is selected, some motherboard does not provide such a function, if there is selected 3Gb / s mode, if there is no not support the transmission rate does not mean 3Gb / s of.The NCQ option is not available, then install the NVSW disk drive, IDEATA in Device Manager in the / ATAPI property, select Channel drives are located in the "Transfermode" box that says "SerialATAGeneration2-3G", where "3G "means that the interface is operating in the hard disk 300MB / S rate of.

  "Enablecommandqueuing" is used to control the opening and closing of NCQ.NCQ stands for "NativeCommandQueuing", and this is because the less "Native" word, so many people misunderstand the function of this option.

  Second, the motherboard and hard drive support transfer rate 300MB / S, BIOS, already correctly arranged, the drive also installed correctly, but the system only detects hard at work or ATA100 pattern 133, with a lot of detection software is thus displayed, it what happend?

  SATA is currently running speed can not be detected, because the operating system support issues for the SATA.Only next-generation operating system (Vista) can be a good solution to this problem, and therefore display.

  ATA100 / 133 is normal, wondering 300MB / S interface speed are not working properly, you can use "HDTACH" test, as long as the burst speed of over 150MB / S, says normal.

  Third, the use NF4 chipset with SATA hard disk.Recently found the lower right corner to add a green icon appears remove the device, and actually had my SATA hard disk click on it, how is this going on here?

  After NF3 / NF4 chipset motherboard with SATA hard drives, and hard drives because the chip set supports Plug and Play characteristics, and disk drive installed NVSW.Resulting in add remove device icons appear right lower leg.However, if the operating system installed on this drive, you simply can not uninstall, there is no need to worry about unloading a hard disk by mistake, it will not affect the performance of the hard disk.Of course, if you want to see is not pleasing to the eye to remove, you can delete NVSW disk drive in the Add or Remove Programs in the Control Panel, but this may lead to a small decline in disk performance.

  Fourth, I bought a new Hitachi 7K80 hard drive support 300MB / S, but it did not work after connected at 300MB / S, motherboard chipset uses NF4 SLI, SATA II support transmission standard, may I ask how to solve it?

  Since NF4 U chipset provides support for both SATA II hard drives, it can be seen that the problem itself is not on the motherboard.(When this happens must first confirm that the motherboard supports an interface speed of 300MB / S, if the motherboard does not support, hastily opened 300MB / S will lead to a hard disk can not be used).

  Hitachi hard disk on the official website, there is a FeatureTools software, this software can help us to solve the problem.However, because the upgrade process can only be done under DOS, so we need to prepare a blank CD-R disc and a burner, if not, it can also be used in place of a floppy disk and floppy drive.

  Hitachi provided in the official website of the ISO file and floppy disk to create a program, have a burner, then you can burn the ISO to boot directly from the CD, or use a floppy disk to create a program to create a floppy disk.After starting FeatureTools, select "Selecteddriver" list SATA 3Gb / s hard drive, a hard disk, for example, Hitachi 7K80, choose "HDS728080PLA380" 7K80 the hard disk, then press "ALT + F" key, opens "Features" on the menu bar menu, select "ChangeSATASerrings"

  In the "ChangeSATASerrings" setting screen, the "MaxTransferSpeed" attribute is set to "Upto3.0Gb / s "In addition," SpreadSpectrumClocking "attribute can enhance the stability of the hard drive, set it to" Enable "can be, determined click" OK "(No matter what attributes to modify an alert box will appear, click" OK "that is, can)

  After completion of setting, to disconnect the power (POWER key is directly off the host), and then restart (Press CTRL + ALT + DEL restart if invalid), then the hard work properly 300MB / S Mode.

  Fifth, in support of 300MB / S rate of hard disk connected only to support compatibility problems occur on 150MB / S motherboard, what is the reason?

  At present such a problem does occur, some hard drive manufacturers to explain this is because the SATA interface protocol problems caused.Currently might appear incompatible motherboard chipset such problems there: VIA''s VT8237 / 8237R / 6420 / 6421L series chip, specific symptoms can not find the hard disk, on the Intel ICH5 / ICH6 Southbridge chipset also has this kind of problem specific symptoms of blue screen ( "19" codes), it is to buy these chipsets friends need to pay more attention when buying a hard disk.
