Why the AHCI mode is disabled in some models of Satellite P200/205?

Hello.

My laptop model is Toshiba Satellite P205-S6277 (PSPBGU-00W016B). Chipset Intel 945 PM Express, Intel 82801 GBM (ICH7-M).

According to the information of the intel.com my laptop processor / chipset are fully compatible with the AHCI mode. But my SATA controller works in IDE compatibility mode and there is no way to enable AHCI SATA mode in the BIOS.

So I have two questions correlated.

1. why this AHCI mode is completely disabled by the BIOS? Is it possible to activate this mode in future versions of BIOS?

2 If this mode is completely disabled by the BIOS in the models of laptop of all PSPBG and PSPB0 then why Intel Matrix Storage Manager (driver that improves the functionality of the AHCI mode) is available at downloads driver recommended for these series of laptop on sites European Canadians, Toshiba and even specially for my Toshiba laptop model on the site?

I already posted the same question to the site we Toshiba but unanswered for a month.
Maybe there is someone who is able to answer this question?

>.. There is no way to enable AHCI SATA mode in the BIOS.
How you tried to activate it exactly?
I have Satellite P200 and the two modes are available. I have model laptop but can not imagine that the AMERICAN models, or models even Canadian work on a different path and BIOS must be the same.

Toshiba service best place where you should ask for help. Call them and ask for explanations. If you are right and the AHCI mode is unavailable, they know why.
Over the past 3 years I have worked with 4 different laptop models and all have absolutely identical SATA settings.

  • Why the excess USB traffic created by some models of the Microsoft Wireless Optical Desktop Receiver?

    As part of my work as a volunteer for a repairman to point not lucrative to registered of Microsoft, I test a selection of mouse and wireless keyboards that are given.  Based on the production of a software tool for USB port monitor, I noticed recently that some models of the Microsoft Wireless Desktop Receiver generate constant even when the keyboard and mouse are slowed traffic USB (about 10 transactions per second) or are completely absent.  This occurs with the 2.1 receiver Microsoft Wireless Optical Desktop (model 1028) and the Microsoft Wireless Desktop receiver 3.1 (also labeled model 1028).  It does not occur with the Microsoft Wireless Optical Desktop Receiver 1. 0a, nor have I watched Microsoft controls only receivers or receivers of Logitech mouse...

    This makes me curious.  What do these receptors with all this chatter?  I assume deliberately, because I see the same thing in all the units I checked.  If I was pretty savvy to decode the trace of the USB, I might be able to figure it out by myself, but I'm not.  I hope that there is someone on this forum who remembers how these old 27 Mhz receivers are designed and who can make me jump the learning curve by giving me an explanation of a layman to what happens here.

  • Satellite P100: How to activate the AHCI mode?

    As all you know, some laptops P100 series are equipped with a controller Intel 82801GBM SATA natively supports the AHCI and with a Fujitsu HDD which takes in charge the NCQ.

    However, the disc is forced in compatibility mode, and therefore the NCQ is disabled, resulting in a loss of performance (which is certainly necessary that laptop hard drives are generally slower than those of office).

    Unfortunately, there is no option in the BIOS which activates the AHCI mode and no tool like HWUtility that can twist that (although it wouldn't work). As far as I know, newer laptops support AHCI mode and there is also an option in the BIOS to enable it.

    Is it possible to activate the AHCI mode in our laptops beloved and make the most of our hard drives?

    Hello

    Do you think that the AHCI is disabled?
    You can run the Intel Chipset ID utility to determine if the ICH7DH SATA controller is already running in AHCI or not.

    However, I studied a little more on other forums that are a little more specific and find this:
    Activate the AHCI on Intel chipsets, without having to reinstall Windows 2000/XP
    http://www.Neowin.NET/forum/index.php?showtopic=457699
    and

    But you know, everything you make are at your own risk!

  • activate the AHCI mode on Envy Dv7 - 7398ca with SSD

    Year old i7 envy Dv7 - 7398ca notebook with SSD Samsung 840 Pro x 256.  Windows 8.1

    I've updated to the SSD shortly after I purchsed the laptop.

    No problem except the Samsung SSD Wizard software keeps tagging me as AHCI mode is disabled and must be enabled and I do not see it in the BIOS.

    Or I see anything that relates in the device as IDE Manager or other.

    It seems that the SSD is optimizing not itself based on the fact that it considers that AHCI is disabled.

    I apologize for the issue being this topic seems to be beaten to death over time, but I do not see what relates to this model or similar.

    Thanks for all the ideas.

    The system is set to ahci or RAID mode. You can tell that by opening the Device Manager and look at the storage controllers. Anyway it is optimized for SSDS and TRIM is activated. You can simply remove the program from Samsung and rest assured that your SSD is optimized.

    That means the AHCI Mode, Mode RAID & SATA IDE Mode in the BIOS settings means

    My computer is having problems when I bought all first it was from another provider which came as a set overclocked PC up the unit everything needed had to be put in my case & add existing hard drives & DVD etc. readers added on the implementation. I used the same location for more than 10 years before that I always built them myself I can build a good setup computer I correspond to different parts inside each other, and then he tested & sent.
    Unfortunately, the store has closed & the owner is sick cannot get their hands on him more & I had to get some add on things like new SSDS & some other bits in my system & the young boy said he would could do this job, but everything went wrong & I lost all new so I decided to recycle me like I used to do it before windows 7-64 came out I was going through a rough patch with me being paraplegic in any case it is difficult to build a new PC, so I chose this store & their confidence that went wrong now & I've been research & learn to catch up with the new technology, I do what I do anyway.
    Thing is my system is never one that you can purchase a manufacturer & I left it with the young boy & it came out all memory & was not necessary but of course upset of that ruined the setting completely overclocked so I did it myself & I got the work faster than ever, & quieter PC I just got the score that he had now , so I'm happy with it, but the names I came across while overclocking I came across that I'm not average or really lot as were dealing with Fast CrossfireX DDR RAM 1600 MHz.
    Please don't tell me that I should not be messing around with what I made since 1989 & made great strides in how everything works, I am not aware about this sort of thing I know SATA what it is & done, but those responsible for setting came from the part of overclocking in the BIOS I put then correctly , but I wanted to know what they represent in more depth. Thanks to anyone who can put me wise on these 3 points only. Malcolm.

    I'm pretty sure that you are on the wrong "forum" for this type of topic. This forum is designed as a support Pro-type Surface ultrabook/tablets and tablet-like Surface.

    That said,

    AHCI - Advanced Host Controller Interface - this is a hardware mechanism that allows the software to communicate with the devices Serial ATA (SATA). It offers features such as connecting hot and native command queuing (NCQ).

    IDE - Integrated Drive Electronics - IDE is basically the 'old' version of AHCI without connection to hot and NCQ. (It is usually used during the era the Parallel ATA (PATA) hard drives)

    Now. Mode AHCI and IDE mode - what is - this? IDE mode is to give you the greatest compatibility with older operating systems. AHCI is as I mentioned above, a modern version of the IDE - use the AHCI mode if you are running recent operating systems (Windows Vista + and Linux kernel 2.6.19+).) IDE mode will allow you to connect older operating systems with SATA drives.

    As I mentioned above, SATA is Serial ATA and the replacement of hard drives Parallel ATA (PATA).

    RAID - this is a storage technology where combine you multiple disks in a unit of 'single', depending on the mode, there may be RAID-0 and RAID-6 and each with different hard drive configurations. I will explain the simple examples: RAID-0 , which is the distribution but no parity or mirroring, this means that there is no data redundancy, if there is a failure on a disc, it will cause the loss of data on the entire RAID array. Ex: You 0110 as writing the data, 01 goes on disk 1 and 10 goes on disc 2, allowing a faster data read/write access.

    RAID-1- This is the opposite of RAID-0, which is mirrored without interlacing (no parity or the other). Basically, this means that you have an exact clone of disk 1 disk 2 disk 1 failure.

    RAID0 + 1 is that both RAID 1 and 0 is, IE interlacing (write data simultaneously to two [or more]. disks more mirroring failure) the minimum amount of disks required for this type of installation is 4 IDENTICAL drives.

    There is also RAID 2, 3, 4, 5, 6. That is just more implemented different configurations of distribution/parity/mirroring on disks.

    That being said, your RAID mode will allow you for some type of RAID configuration, if you choose to do so.

    Supplement: Many SATA controllers can enable AHCI separately or in combination with RAID support. Recommend Intel choose RAID mode on their motherboards, allowing also the AHCI, rather than AHCI/SATA mode for maximum flexibility (in the case that you ever want to build a RAID array), because there are a few problems that occurs, usually BSOD, when you choose a different mode once an operating system is already installed.

  • Why the 'Analyze' button is disabled?

    I was wondering why the 'Analysis' button is disabled in the new disk optimizer tool. I'm able to optimize partitions of hard drive of my computer as usual, but I can't check if it must be optimised beforehand.

    Is the drive a SSD or Solid State Drive?  If so, that's why.  These readers of should not or never be defragmented.  It puts much wear and tear on the device that have a shorter life expectancy.

    Hello.

    XP and Seven is installed in dual-boot on my laptop and I use EasyBCD to choose which system I want to start.

    To start XP, I need to enable "Compatibility" (Controller SATA in BIOS mode) and seven is "AHCI" must be activated.

    Is there a way for my two OS was started without making changes in the bios?
    Y at - it an update to correct this problem (or alternative)?

    Thank you in advance.
    Marc

    Yes you can do it but I'm afraid, you must reinstall Windows XP Home edition m.
    Why? Because before beginning to install Windows XP Home edition, you must change it to AHCI mode, launch the installation of Windows XP Home edition and before you start you need to load the SATA driver (via F6 I think).

    Long time ago, we have discussed a lot about this on this forum then use the advanced search anc check options other postings on this subject.

  • TRIM does not not despite the AHCI mode and fsutil behavior query disabledeletenotify to return 0

    Hello

    I recently changed my motherboard to a gigabyte a ASRock x 79 Extreme9.

    After this of course being the new is configured to AHCI mode and update an existing installation of Win 7 x 64 drivers using the DVD provided by ASRock, I used trimcheck - 0.7.exe to check if the trim was working, and he's not. Trim was collaborating with the Gigabyte mobo.

    I made sure also that HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci\\\ and HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV starting value was 0, does not.

    Device Manager shows that my 2 SSD using a SCSI driver, which might be the source of the problem. I tried to update the driver automatically, but Windows kept existing ones, saying that he could not find better.

    No idea what is the problem and how to solve?

    Thank you.

    ASRock has suggested to do a new clean install W7, and it worked.

    Installation on the previous mobo was a unique one partition boot, and the new is a type of 3-partition GPT.

    TRIM was working on the previous mobo, but anyway when re-use of previous installation even with new pilots was not.

    So, it was a problem of Windows, but that appeared to require a clean install to fix.

    Thanks for the reply.

    I've experimented with itemRenderers without success. The problem was that I used the canvas. After your post I realized that there is a class dedicated to it. To work with 4.1 simply have ADG like this:

    itemRenderer = "ADGItemRenderer."

    dataProvider = "{advancedDataGridDataProvider}".

    ID = "advancedDataGrid"

    designViewDataType = "flat".

    selectionMode = "multipleCells."

    left = "10".

    Top = "10".

    right = "10".

    Low = "10" >

    dataField = "col1" / >

    dataField = "col2" / >

    dataField = "col3" / >

    ADGItemRenderer is defined as follows:

    http://ns.Adobe.com/MXML/2009.

    xmlns:s = "library://ns.adobe.com/flex/spark".

    xmlns:MX = "library://ns.adobe.com/flex/mx".

    focusEnabled = "true" >

    left = '0 '.

    Text = "{listdata.label}" "

    Red = '0' / >

    As you can see menu contex is yet ADG but items on the Clipboard are now activated.

    The same trick does not work well in 3.5. It does not work with AdvancedDataGridItemRenderer. I moved ContextMenu of Assistant Director General to AdvancedDataGridItemRenderer like this:

    http://www.Adobe.com/2006/mxml '.

    xmlns:UI = "" Flash.UI. * ""

    Copy = "clipboardHandler (Event)" "

    Paste = "clipboardHandler (Event)" "

    Cut = "clipboardHandler (Event)" "

    selectAll = "clipboardHandler (event)" "

    Clear = "clipboardHandler (Event)" > "

    Import mx.controls.Alert;

    protected function clipboardHandler(event:Event):void

    {

    Alert.Show (Event.type);

    }

    ]]>

    ID = "adgContextMenu" >

    cut = 'true '.

    Paste = 'true '.

    selectAll = 'true '.

    clear = "true" / >

    The items are always disabled. WTH?

    Fortunately, it works with AdvancedDataGrid ItemRendererGroup(which, I guess, has a slightly different effect). If I define ADG itemRenderer just like that (keeping ContextMenu to ADG):

    http://www.Adobe.com/2006/mxml"/ >

    then the items on the Clipboard are enabled. Crazy.

  • Why the HARD disk is partitioned into C & D on Satellite Pro C partition

    Why the HARD drive is divided and how to use it?

    Thanks for any help

    Ken

    Hello

    The HARD disk is partitioned and contains two partitions. The C partition is the system partition that contains the Windows operating system. The second D partition contains data drive HARD recovery.
    HARD drive recovery allows you to establish the notebook back to factory settings without the recovery disk usage.

    But it s is strongly recommended to create the recovery disk! The user manual provides the info on that in case something goes wrong with the HARD drive, the recovery disk allows you to recover the laptop.

    Of course, you can delete the D partition if you want to, but before doing so, you must create the recovery disk.

    However, my HARD drive contains 3 partitions. I created an extra. In my case, the C partition contains only system and the unique software. My files private like Mp3, movies, etc. are placed on the D second partition).
    The third partition (E) contains a folder with games.
