Cannot change SATA RAID in AHCI mode in the BIOS.

Hi, I use Pavilion p6142p Desktop, WIN7, a harddsik.  The SATA BIOS has been set to RAID by the default value of the factory.

I put two new hard drive in this office, they have different sizes and different rpm speed, I don't want their RAID.  So I tried switch the BIOS SATA AHCI mode, so I can't start the win7, win7 gave me two choices: repair or return, repair is not too.  After I change the BIOS, everything is OK.

But I have to put all three harddisk in this office. So my question is:

I use RAID in this PC?

Do I have to re - install win7?

....

In any case, what should I do?  Thank you.

d1ad1a,

RAID will work with unlike devices.  You can always install your new discs and give it a go.

It seems that the ugly way is going to be your only for the ACHI mode to work. Alternatively, just live with what you have.

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

    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 is it in the laptop Sat L100 that there is no option in the BIOS-> advanced where in I can change the drive to SATA?
    I saw it in another PC Toshiba laptop

    Hello

    If this option is NOT available in the BIOS, then you will not be able to change that!
    In this case the controller HARD drive will tell in SATA mode and if you want to install an operating system then you need to install the SATA drivers first!

    CD..

    To my knowledge, the Satellite P300 series BIOS doesn t contain the ability to switch the AHCI compatible mode.

    I don t think that even after updating the BIOS such option would be available in the BIOS.

    I see on the first screenshot of the BIOS, the SSD drive is connected to the second controller.
    I recommend you connect the SSD to the first controller (instead of the HARD disk).
    Maybe then you could get better performance.

    Just for the note: portable computers with a graphics card ATI supports the AMD chipset, and in this case the ATI graphics card driver contains the SATA driver files.

    However, I guess the HARD disk controller specification allows the use of better performance of SSD drive.

  • Desktop computer HP P6813w there a RAID option for drives in the BIOS?

    Hello

    Looking to buy one of these HP p6813w.

    I was wondering if the BIOS supports RAID 2 discs.

    One-piece

    Hi one-piece,.

    Boot in the bios (F10 setup) and get off at the fall of peak.  Look at the setting for the sata controller mode and see if you have an option to select RAID.  I do not think that the motherboard in the P6813w RAID capacity according to the information I've seen made available by HP.

    If you really want to RAID, then you could buy a RAID PCI card - E to support two data disks.

  • Don't Win 7, no logon, safe mode or the bios

    I have a Lenova PC with Win 7 pro installed. Yesterday, there was an automatic update. I can't login, run safe mode, or enter the bios. I did NOT forget my password to login and read the forums for about four hours now, trying every suggestion without success. Everything seems to want the password. for example. Run the command. Other ideas would be appreciated. At this point I don't care even to do a full format and reinstall. I need the bios to boot from cd or usb, however. I have saved on both os.

    Thank you for a very frustrated man who thinks that perhaps he should have done the free upgrade win 10?

    Wait a minute.

    "My wife is also a user...". I am all about this account. »

    So you can start the computer and log into Windows normally - you just cannot log in to your account, that is be the only 'administrator' account that you created.  Is this correct?

    It is a Lenovo desktop/Tower computer?

    You have a Windows 7 installation DVD or a "system repair disc" (this is something would have created you, not a disc provided by Lenovo) by chance?

    I think that by using a wired keyboard allows you to enter in Safe Mode and the configuration of the BIOS utility.  Once in safe mode, you should be able to use the system to go back before the updates restore corrupted your profile.  If this does not work, you will probably need a Windows 7 installation DVD or a "system repair disc.  If you don't have one of those, there are methods to move forward, but Microsoft's policy forbids us to give such advice.

  • Tecra A9: Cannot enable or disable Multi Core processing in the BIOS

    To the old Bios version (1.50), it has been possible.

    Now I use the most recent (2.10) and I can't move the cursor to this selection.

    The special key strokes?

    If this isn't the case - where can I download the previous version of the bios where this selection is possible?

    Thank you

    Ulli

    Hello

    > Otherwise - where can I download the previous version of the bios where this selection is possible?
    This is not possible because it is always the newest available BIOS can be downloaded.

    With regard to the option in the BIOS.
    Do you mean you are not able to choose this option or you can't change the value?

    Toshiba BIOS:
    Usually the buttons PgUp / PdDn would change the BIOS page. The arrow buttons to select items. SPACE or BkSp can be used to change the values.

    But note; You can only change the value if it s interchangeable. But many options appear in the BIOS but is not editable.

    In Illustrator CC, I have a text with background colors and contour, and I hang outside the text, not half-n-half. From what I can read (for example Why can't fix us a line of text to the outside (as in InDesign) without having to first convert them into text vectorized?), the way to do that is in the appearance Panel, dragging filling to the top or the race down. But they don't change places when I try - I drag, but nothing changes. And in the Panel advanced stroke, the second and third options to align the lines appear dimmed.

    If I saw the text, then all the choices to align the shots are allowed, but I prefer to do it with the living text. Is this possible?
