new hard drive for laptop

I have a laptop dv7-3140el and HD samsung HM641JI 640GB 2.5 "SATA 5400 RPM (to replace car failure). To buy a new hard drive I have to take the same or I can take 7200 RPM instead of 5400? What technical specifications should I look for when buying a hard drive for computer laptop dv7-3140el? I wouldn't make a bad purchase!

Sorry for my bad English



Here are a few points to note when replacing your HARD drive:

You are not limited to any particular drive manufacturer.

The speed of rotation of the disc can be 5400 RPM or 7200 RPM

The new drive HARD should be at least the same capacity (or slightly more is okay) as the original drive - mounting a drive smaller than the original often causes risks with recovery media.

The player at the link below is an example of one that would be perfect for your laptop.

750 GB hard drive for laptop.

If necessary, the procedure to replace the hard drive begins on Page 47 of your maintenance & Service Guide.

Kind regards

  • I can install Windows 7 on a new hard drive for HP Envy m6 1205dx

    My HP Envy m6-1205dx son is a notebook of 2013. The screen was broken and I replaced one. Now he says that there is not a BONE, I tried to install a full version of Windows 7 Professional, and he said that he there was not a boot device. I've reconfigured the BIOS to boot with the CD/DVD ROM and it started installing. When he arrives at the point of asking where to put the installation there is no option. I checked the connection to the hard drive and it is not a problem here. I think to buy a new hard drive to install the Windows 7 operating system, I am afraid that it will not work or he will say that I need to install the drivers. This laptop originally supplied with Windows 8. Can I install this version of Windows on this laptop? If I need to install the drivers how can I get them? It cannot be a website to download the drivers on your computer. I can't do without the computer having an operating system. I downloaded some drivers from a link, I saw on You Tube and put it on a flash drive, but none was consistent, one of them did read on a different/more older computer I tried to install this OS on and it says that the driver was out of date. It seems to me that a (FULL VERSION) drivers and everything else you might need. I'm not computer savvy, so I do not know! I'm just trying to save my investment of $600 on this computer without spending $300. I can get a new hard drive for $80 and it was on that I would go; However, I will buy a new Windows 8 operating system if it is the only option.

    There is no device driver Windows 7 for your model, only Windows 8:

    If there is no driver, your PC may not work correctly (No. LAN or WiFi, Audio, USB, etc.) after the installation of Windows 7.

    Check your hard drive, if the laptop has been abandoned the drive may be defective and must be replaced.

    If you are using a real MS win dvd during the first part of the installation it can not find a drive or ask a driver, then the driver is obtained from Dell, specific to your model, its likely the driver sata, you need to download to say a USB and then point to this file when the installation application the third-party driver.

  • I have to make a new hard drive for my Toshiba laptop, how do I get my current operating system (Vista) on the new hard drive?

    I already have Vista running. Last week I had to run the recovery disc that came with my laptop, now I am hearing cracking and screetching coming from the hard drive and it does not start. I intend to buy a new hard drive and replace it myself. How can I move the new Vista of the old hard drive?

    My computer did come with an installation disc, only a recovery disk.

    Probably you need to use the product key on your computer to activate Windows.

  • New hard drive for compaq presario c500 running vista. I want to switch to windows 7

    I'm fixing my laptop aunts. He a presario c500 compaq running windows vista. I bought a new hard drive. I would like to install windows 7. She could get windows 7 discs for free when she got off the computer, windows 7 was not yet. They have offered free windows 7 for people who bought the PC just before its release. Is it too late? I guess it's too late. Is there anyway I can get windows 7 for free? Or is there any discount for the upgrade to vista. I can't afford windows 7 discs.

    In my opinion, it's too late to get a free version or price reduced from Windows 7. This offer was available about two or three years, if my memory is good.

    You can Contact HP and ask.

    Best regards

  • HP TouchSmart 420 - 1000 t CTO: need help with the installation of windows on a new hard drive for HP TouchSmart 420-1000 t CTO (bought in 2012)

    My hard drive is failng in my computer I get the message that "the failure of hard drive" is imminent for several months now.  I did just recovery disks after I bought my computer and that you have ordered a new hard drive.

    I thought that the part of the setup of windows on a portion of the current hard disk that I need to replace.

    I want to just make sure that if I can restore the windows completely and that all programmes provided with the computer are on the recovery discs I want to do it myself - so I need to know I'm doing it correctly!

    Thank you very much.


    PS I found this web page below and I want to just make sure that it applies to me:

    This link in the post seems to apply to the situation.  If you have already completed the defined recovery disc then it should just be a matter of running the recovery disc after the new hard drive is installed.  The recovery disk set will be "restoring windows completely and all programs included with the computer".  Be aware that all other items that were installed or personal data will not be restored.  When replacing the hard drive, do not buy a disc exceeds the limit of 2 TB, such as published in the SPECS for TouchSmart 420-1000 t CTO.

    I just installed a new hard drive in my laptop with Windows 7 Pro 64 bit.
    Would it not be possible to install WIn XP or Win 98 + older software (Win 98 or XP) on an external hard drive, then plug it into USB, laptop, in order to run old programs of 16-32 bit?

    It would be best to run Windows 98 or XP in a Virtual Machine, if you need to run older programs.

    You can use a free software such as Oracle VirtualBox or VMware Player:
