  • Change the drive letter of the Partition Recovery

    After previous bad experiences in trying to separate the data files program, I took the habit on my previous computer under Windows to create another partition on my hard drive to store the data files. Out of habit I still do on my desktop PC with Windows XP (great program) rather than use the My Documents folder.

    I want to do the same thing on my new DV6-3142, I use to work and create a separate partition for my data files. I understand how to create a new partition on the HDD and reassign the drive letters for the existing partitions, but I want to use the letter D for her. However, it is the letter of the drive that is used for the recovery partition.

    Can I change the drive letter of the recovery partition to, say R without affecting the operation of the recovery process, or should I leave as D for the recovery of the system to work properly that I should never need her?

    Hello:

    You leave the name of the recovery partition and drive letter unchanged and your C drive: of the same name.

    If you change these, when you press the F11 key to start the recovery process, the program know what to do.

    I am a firm believer of it also have a set of factory recovery disks. For me, it is worth less than the investment of $20.  If your HARD drive fails after the warranty period, (or if you want to upgrade your HARD drive), your recovery partition doesn't help anyway.

  • How to change the drive letter with installed applications?

    My window is installed on the C: drive, and the application is installed on the D: drive,

    I just buy a new HARD drive and put it into drive E:, everything is copied from drive D: to E: drive and want to switch between the letter D: and E:.

    I tried to put in DISKPART, but when I restart my XP, the drive letter remains the same,

    If I change the drive letter directly in XP, it cannot be changed, because the applications are running.

    Does anyone have any suggestions?

    Thanks in advance for your suggestions

    Make sure any DVD/CD or USB keys are not connected or set F assignments or beyond (MY DVD is S & T).

    Shut down the computer; power off. Disconnect the old drive (now D). Connect the new drive (now a copy of the old D). Power and boot to the desktop. Go into disk management and make sure the drive that contains Windows, the original C drive is always c. assign the new drive as D. Reboot the desktop. Check operation.

    Shut down the computer; power off. Plug the old drive. Restart the desktop computer. Enter Disk Management and assign it to E.

    Restart, then check the operation.

    Seagate 2.5 "laptop hard drive - USB
    also tried with Maxtor external hard drive 3.5 "

    Hello

    I have two laptops running Vista. On each of them, I have an external USB or SATA drive that I use as a backup partition.
    I have my own backup utility, and I like to use the letter B for the backup.

    When I change sometimes the discs I've met this parameter is incorrect problem on two computers - sometimes I can change using the method above and sometimes I can't.  I tried to stop the disk cache, anti-virus etc etc etc. with totally inconsistent results so far as I can tell.

    Today I tried to boot mode safe mode (F8 at startup) and tried the same steps as before and it worked on the first attempt.

    Maybe it's worth a try.

  • How can I change the drive letter assigned to the partition of 'winretools' on a laptop Win 8?

    I'm just going through the process to customize a new Inspiron 14z with Windows 8. The only thing that left me speechless are all provided partitions installed on drive, thanks to a combination of everything be different on Win8, Dell make their own way and GPT formatting.  Generally, I would like to know what the devil all these partitions are for, but it is fine if it will be a slow learning process.  More precisely and immediately, I need to change the drive letter assigned to the partition of 'WINRETOOLS '.  Currently it is D:, and the problem is that 10 years from now, I'm using as my data partition D: and a number of applications, configurations, settings, etc. assume that all my files are on D:.  For example, by having all my music on D:, I can sync iTunes library and preference between machines and all results files and playlists is from a machine to another.  Same thing for my photos.  Same for a bunch of utilities like FTP consoles, sync utilities...

    In an earlier version of Windows, I would just go into management drives, right click on the partition in question, assign a different drive letter and work done.  On my machine, the WINRETOOL 2 GB partition shows not even as having a drive letter in disk management, despite the fact that it is D: in Win Explorer.  In addition, only the right click option is 'help '.  I took this option, and, despite its aspirations, it is not useful.

    How can I change this drive letter to something else?  WINRETOOLS should even have a drive letter in Explorer (some messages that I've seen indicates that it must be hidden)?  If I change the drive letter, which will break its function, whatever it is?

    ....

    My machine has a 500 GB of rotating disk that has all of the above partitions.  I shrunk the 80 GB C: partition, to create a data partition.  I've not yet formatted the unallocated space I want to solve this WINRETOOLS thing first.  Finally, there is a 32 GB of SSD that I put in place as a cache of the Intel Smart Response, and it is no longer visible to the operating system.

    At the command prompt, type the following and press "enter":

    mountvol D:\/d

    Close the command prompt.

    Drive D: letter should now be available and not used.

    Here's some info about Mountvol, it's very powerful to be safe to use it:

  • Is it possible to change the drive letter or to hide the partition System Reserved (D :)?

    I just bought a new computer with Windows 7 and there is a reserved partition mapped to D:, I prefer to use for the DVD player. Is it possible that I can out of this drive letter, or would have done so cause problems?

    Hello and welcome!

    As you can change the drive letter, I would recommend that you do not have. The system partition reserved y at - it crashes or recovery.

    Drive letter E is usually by default for CD-ROM.

  • Try to change the drive letter, but get the error "the parameter is incorrect."

    I am trying to upgrade my PC to run Windows 7 64 - bit on a new Intel Solid State Drive (SSD). I install Windows 7 from scratch on the new SSD (which uses the drive letter J) have just completed and changed the drive letter of my original system from C to M.

    My intention was to reuse the drive letter C to the SSD, but the Win 7 disk management tool will not allow the use of C. "All I get is a' setting is incorrect" error message.

    My first thought was to check the location of the Windows page file. It was indeed using drive J, so I put the pagefile on the D drive instead and restarted my PC.  However, this has not fixed the problem. I always get "the parameter is incorrect" when I try to use the letter C.

    What else could be the cause of this problem?

    David

    I tried a change of the HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices registry but it is just screwed to the top of the new installation of Windows on the SSD (it starts in a unusable mode "is not a real installation"). I was not too concerned by what I had already made my decision to reinstall Windows 7 after making changes in bios to disable all disks except the SSD and force a boot from the installation of Win 7 DVD.

    This relocation is now complete and the new partition on the SSD system has the C drive letter. A reboot with the other shows, active records that the original disc of BONE has been reassigned to the next available drive letter.

    My problem is thus solved. If it was the only way to do so is now a moot point.

  • Need help to change the new "new tab".

    My new custom tab, google, is no longer opens. New tab in Firefox is shit, how can I change this back?

    I used the topic: method of config to change it for a while, but now the chain is simply ignored.

    41 of Firefox is no longer uses the browser.newtab.url setting in about: config because he was constantly attacked by malware. From 41 of Firefox, you need an add-on to change the new tab page.

    Here are a few options (I'm learning more all the time):

    • If you are already using the extension classic restaurateur theme: There is an option somewhere (!) in his dialogues of the parameters to select another page in the new tab.

    Use only one of these methods at the same time, otherwise there may be conflicts and dysfunctions.

    Setting up substitute new tab and new tab custom

    After installing one of these extensions, you must use the Options page to set the new desired tab page (instead of use subject: config).

    Open the page modules using either:

    • CTRL + SHIFT + a (Mac: Cmd + shift + a)
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then on the side right, find the new tab replace or custom new tab and click on the Options button. (See first screenshot attached).

    New tab Override

    Depending on the size of your screen, you may need to scroll down to enter the address in the form. (See second screenshot attached). For example:

    • (Default) page thumbnails = > subject: newtab
    • Blank tab = > subject: empty
    • Built-in Firefox homepage = > topic: welcome
    • Any other page = > full URL of the page

    Then tab or click this form field and you can test using Ctrl + t.

    Custom new tab

    It is easy to enter your favourite homepage address. If you check either of the boxes, the expansion will set the focus in the page as well, for example, the cursor will be in the Google search box. (See third screenshot attached). I had to leave Firefox and start it up again before new custom tab started working, but this may have been due to tests so many extensions back to back.

    Success?

  • Can I change the drive letter of the recovery partition?

    HP P7-1235, Win7 64 bit running. 1 TB HARD DRIVE

    I usually partition my hard drive, so that my data is separate from the operating system and applications.  the operating system is the C: partition, and my data is generally D:.  The problem is: "D:" is used by the recovery partition.

    I can change his letter to something else, and recovery still works?

    Hello

    Well, everything has been said on this subject and its okay.

    It's better to not touch the D: partition, set another letter to your other partiion, if you change the recovery partition, you won't be able to use it.

    But you can also do a thing, you can go ahead and create your copy of the recovery disks, just enter some DVD, create your copy of the recovery Image, then you can change the drive letter of the partition Recovery to E: or even delete that.

    A copy of records RRS, you can always use them to again state of the plant, and that will reformat all your partitions, create the recovery disks and do what you want and prefer with you D: partiion.

    Thank you

    If a MacBook Pro RAM and drvie hard can be modified/improved depends on the submodel and we do not know yours. There are dozens of variations of the MacBook Pro issued since 2006, and you do not want guessing us!

  • Change the drive letter for the recovery partition

    The recovery partition is, by default, the value to D: which means that if I create a data partition, it is automatically in letters f: while this is not unacceptable, it is inconvenient.  I would like to change the drive letter of the partition data on D: and set the recovery as f partition: if I do this, it will automatically disable the ability to recover?  I am running Windows 7 Professional, which is an originally installed Windows 7 Home Premium upgrade.

    Hello Richard9, if you change the Recovery D: HP restore partition to another letter, the recovery procedure would not work if you ever need.

    If you have files HP Recovery discs, you could delete this partition and recover the capacity of hard drive D: and use the set of diskettes to restore HP recovery to reintall the original software and the partitions of the hard drive, all as they were when shipped from HP.

  • cannot change the drive letter of the external hard drive in XP

    I bought an Iomega 1 TB external hard drive and I can not change the drive letter.  I have a click right on my computer and select manage.  When I click on disk management, it does not recognize the outside.  The weird part is that it appears in my computer and I can access the drive without problem.  I disconnected the drive of my XP machine and connected to my Vista laptop and I was able to access it through the management of the disks without problem.  Iomega support claims that it is most likely a problem with my XP machine.  Any ideas how to solve this problem?

    Hello rolandboy,

    Thank you for visiting the Microsoft answers community.

    Try to use diskpart to complete the task.

    -Click Start > run > type diskpart and press enter
    -At the prompt, type list volume , press enter
    -At the prompt, type select volume 1 (where 1 is the number of the volume is the volume that you need to change the drive letter)
      
    -At the prompt, type assign letter = A (where A is the letter you want to assign your volume)

    Close your CMD, and you should be finished.

  • Change the drive letter of recovery drive (vista home 64)

    I can change it from d to z: I need d: for another purpose.

    Thank you

    Peter

    PeterK514,

    It is safe to change the drive letter as long as no other program or service is dependent on growing location. The recovery discs, usually access you their data outside of the windows environment and the recovery console (by pressing a button of keyboard during startup), and so it would be prudent change the assigned letter. However if your recovery for you program manufacturer, or any other software that relies on this drive, run from Vista, it can interfere with its ability to operate properly. Consult your OEM for more details on their dependencies of the program.
