PCV-W20 Partition sizes

Good day
I tried to run the system recovery disks when I had the following messages; Error Cannot Recover. Hard drive size too small.
Click on OK and the following message comes up
VAIO System Recovery Utility
Cannot normally execute the initial setting of partition information. This utility exits and your computer is rebooted.

I need to know what size the partitions should be so I can run this recovery disk. Also is there anything special I need to do when I setup the recovery partition?
All help is greatly appreciated!!

I don't have recovery partition

follow this step and do it. God bless you

  • To create a partition from a new or newly formatted computer, make sure Windows is installed. Load any programs and drivers you would like to keep in case you need to back up to a previous version of your computer's settings.

  • 2

    Install your partition creation software; in this article we will use Norton Ghost. Before creating your partition, disable any anti virus and other scanning software.

  • 3

    Create your partition by going to your ms-dos prompt: from your Start menu, press "Run," and type "cmd" without quotations in the run dialog box. At the dos prompt, type "fdisk" without quotations, and choose option 1 (Create DOS partition or Logical DOS Drive). Set the partition size to 10 GB at press enter.

  • 4

    Open Norton Ghost and follow the instructions to create a recovery partition in the new partition you had just created. The process should take anywhere from one to three hours, depending on the size of the files you are going to back up.

  • 5

    Restart your computer. When done, open Norton Ghost to verify that the Recovery Partition was created.

    Hard Disk Data Recovery

    Definition of Hard Disk: Hard Drive is a storage device where you can store any types of data and file. Hard Drive is available as external and internal device. We know PC storage device as internal system Hard Disk. When you save data or install programs on your computer, the information is typically written to your Hard Disk. The Hard Disk is a spindle of magnetic disks, called platters, that record and store information. There are several interface standards for passing data between a Hard Disk and a computer. The most common are IDE and SCSI. Hard Disk is made of one or more aluminium or glass platters, coated with a ferromagnetic material. Most Hard Disks are found as Parallel ATA (PATA), Serial ATA (SATA) or SCSI device.

    Difference with Floppy Drive:
    The term hard is used to distinguish it from a soft, or floppy, disk. Hard Disks hold more data and also faster than floppy disks. As an example a Hard Disk can store anywhere from 10 to more than 100 gigabytes, where most floppies have a maximum storage capacity of 1.4 megabytes. Floppy is more risky device than Hard Disk for losing data.
    Problem with Hard Disk:

    Most common problems of Hard Disk which may arise anytime are Booting problem, OS Installation problem, Hard drive crashing and another Hard Disk not showing original space or not showing partition etc. But in every case the risk is loss of data. In some of cases formatting and reloading of Operating System can recover your Hard drive and make it useful but formatting can recover a blank Hard Disk only without data. But you have to recover Hard Disk with data, so formatting is not possible.

    Data Recovery:

    Data recovery is the process of retrieving back data from the damaged media. The damage of storage media can be physical damage and logical damage. The data is retrieved back by recovery experts after determining the type of the damage caused to the storage media. Most of cases data recovery is important and formatting is not possible there. So that I need to choose another way for solution of this type of problems of Hard Disk. The first and secure way to recover a Hard Disk is using data recovery software.

    Recover Data from crashed Hard Disk: Power surges, Software Corruption or Malfunction, Hardware or system failure, Natural calamities, User errors may crash your Hard Drive. Data recovery software helps to retrieve or recover the data from the crashed hard Drive. Data recovery software gives an easy and Graphical User Interface with less difficulty so that the data can be recovered easily. The recovery software helps to recover the data and restore them on a second Hard Disk, the Hard Disk being connected to the computer and recognized by the BIOS, the recovered data can be stored on a safe location on the second disk.

    Logical data recovery: In a data loss situation when the Hard Drive is perfectly fine and the BIOS recognizes the Hard Drive but reports a read error, logical data recovery technique is very helpful. Here the files that are damaged or corrupted by any user error or virus attack are rebuilt rather than repairing the Hard Drive.

    Fragmentation: When the FAT entry is lost during accidental file deletion, formatting or partition deletion that particular block of Hard Drive becomes inaccessible. Some data recovery software makes an attempt to rebuild the files without a FAT entry. This technique is very efficient if the file size is smaller than the clusters size. But it is inefficient in recovery the larger files.

    Data Recovery from deleted partition: Partition is allocation of memory in different sections. Each partition will be like separate disk drives. Partition is very use full when the user is using operating systems more than one. Usually after formatting the disk it may not be able to recognize a partition because of accidental deletion of the partition table or by virus infection. The partition is not actually deleted; it can be recovered by using recovery tools and copy the data present in the partition to the required destination. Formatting the drive erases a large amount of data present on it, but not all the data. The recovery of the data depends on the fragmentation of the file system as the parts of files are being placed on different places in the drive. The data recovery software will assume that files were not fragmented and stored in continuous clusters. If the partition was formatted using different file system, then recovery process will be very complicated.

    Another Data recovery process: If you don't have any data recovery software you can try another process to recover data. Attach the Hard Drive with another system in slave or second SATA.If detect the drive then boot to the first Hard Drive and use the bad Hard Drive as secondary. Then you can copy the data from the second drive to first drive easily. Here have another process to recover data from a crashed Hard Disk. But it is so risky, and should not try to do this for an inexpert person. First pack the Hard Disk in a bag properly where moisture can't attack. Now freeze it upto get chill. After freezing quickly attach with a system in secondary, and copy the data within the Drive will come in room temperature.

    So the most secure process to recover data from a Hard Disk is to use data recovery software. It is available in market.

    How to fix No Bootable Media Error Message

    FAT (File Allocation Table) is one of the most widely used file systems used now-a-days with various versions of Windows operating systems and memory cards. Every logical partition contains a FAT that consists of file allocation information and the information of free allocation units that need to be assigned to files. Although the FAT file system is reliable, corruption still occurs due to various reasons. In such situations of FAT corruption, your system becomes unbootable, resulting into inaccessibility of data saved in FAT based hard drive. To access the data after FAT file system damage, an easy way is to restore the data from an updated backup. But, with inaccessibility of data backup or backup falling short to restore the required data, an ideal option left is to use an advanced FAT Data Recoveryapplication that can recover the lost data.

    To illustrate the above scenario, consider a practical case the below error message pops up when you attempt to boot your system:

    “No Bootable Media”

    As the above error message appears at the time of booting the system, you wont be able to access the data saved in the hard drive.


    The above error message because the FAT file system has been corrupted. Few main causes for file system damage are improper system shutdown, human errors, and virus attack.


    To isolate the above error message and to access the data after the above error message appears, you will need to follow the below steps:

    Run CHKDSK utility to repair the FAT file system. If the problem persists, format the hard drive.

    While the latter resolution resolves the above error message completely, it also deletes the data saved on your hard drive. In such cases, if the backup is not available, then you can only recover your formatted data by using an advanced third-party FAT Data Recovery software.

    A FAT Partition Recovery utility thoroughly scans a FAT based hard drive and recovers almost all data, even after formatting. The data recovery utility can be downloaded from the Internet.

    Stellar Phoenix Windows Data Recovery is an efficient FAT Partition Recovery tool that recover lost, deleted, and formatted data from both FAT (FAT12, FAT16, FAT32, VFAT) and NTFS (NTFS, and NTFS5 ) based hard drives. The detailed help manual attached with the tool allows even a new user to perform recovery easily without any technical knowledge. It supports Windows 7, Vista, XP, 2003, and 2000.

    Do I need a special Hard Drive fro my /sony PCV-W20??

    Your system uses an IDE Hard drive interface, so make sure the hard drive you get has an IDE interface. I believe there is no limit to the capacity size. I would also recommend going to Sony support and search for a BIOS update. This will make sure that any limits on drive capacity are resolved.

    I want to downgrade my desktop acer aspire x1800 vista to xp pro everytime i run set-up it always showing me an error could not proceed,.

    Most like ly the hard drive has a Vista recovery partition. That partition has got to be deleted. You'll need to open a command prompt and follow the guide very carefully or irreperable damage could occur.

    Here’s the trick to delete and remove the EISA recovery or diagnostic partition in Vista. Before proceeding with the deletion action, make sure that at least a set of Recovery Disc Media has been created. Else, you won’t be able to restore your computer to working and factory default condition when any problem on PC requires reinstallation.
    1. Open a command prompt as administrator.
    2. Run Diskpart application by typing Diskpart in the command prompt.
    3. In the “Diskpart” prompt, enter rescan command and press Enter key to re-scan all partitions, volumes and drives available.
    4. Then type in list disk and press Enter key to show all hard disk drive available.
    5. Select the disk that contains the partition you want to remove. Normally, with just 1 hard disk, it will be disk 0. So the command will be:
    select disk 0
    Finish by Enter key.
    1. Type list partition and press Enter key to show all available and created partition in the disk selected.
    2. Select the partition that wanted to be deleted by using the following command, followed by Enter key:
    select partition x
    where x is the number of the EISA based recovery partition to be removed and unlocked its space. Be careful with the number of this partition, as wrong number may get data wipes off.
    1. Finally, type in delete partition override and press Enter key.
    Once the partition has been deleted, exit from Diskpart, and now users can use the much familiar and much easier Disk Management tool in Windows (diskmgmt.msc) to manipulate the freed unallocated partition. Users can create a new volume (partition) with this space, or simply merge it to existing partition by extending the size of the existing partition.

    I am having the same difficulties as you!
    If you have compressed the hard disk drive using the Compress drive to save disk space option under the Properties menu for your hard disk drive and have performed a non-destructive recovery or a system recovery, the following error message may appear: NTLDR is compressed. Press CRTL-ALT-DEL to restart. This error message is resolved by following these steps:
    1. Insert the HP Recovery Tools CD or Compaq Recovery Tools CD into the CD drive on the computer and restart the computer.Wait for the HP Recovery Tools CD or Compaq Recovery Tools CD window to open.
    2. Select Run Microsoft Recovery Console , click Next , and then follow the onscreen instructions. NOTE: If you are unable to open a recovery console, follow the Alternate steps .
    3. Press R to repair the Windows XP installation using Recovery Console.
    4. Enter the appropriate number for the WINDOWS installation, for example, the WINDOWS installation could be listed as 3: C:\WINDOWS or 3: D:\WINDOWS .
    5. If prompted, enter your Administrator password and press Enter . If there is no password, just press Enter .
    6. At the prompt, if the WINDOWS installation you selected in Step 4 was C:\WINDOWS, type: cd c:\Or, if the WINDOWS installation you selected in Step 4 was D:\WINDOWS, type: cd d:\
    7. At the prompt, type: attrib -c ntldr and then press Enter .
    8. At the prompt, type: exit
    9. Press the Enter key and immediately remove all discs or diskettes from the computer to allow the computer to restart.The error message should be resolved.
    Alternate steps NOTE: These alternate steps work for HP and Compaq desktop PCs with Windows XP and a recovery partition. (M0st HP and Compaq PCs with Windows XP have a recovery partition on the hard disk drive.) These steps do not work if you have replaced the hard disk drive, replaced Windows with another operating system, or repartitioned the recovery partition.You can use the following steps if you are unable to open a recovery console:
    1. Turn on the computer. When the initial logo screen appears, press the F10 key repeatedly until a message about starting recovery appears.
    2. At the Recovery screen, click Advanced Options and then press the Alt and D keys at the same time to go to a command prompt.
    3. At the command prompt, enter the following: diskpart
    4. At the command prompt, enter the following: list volume
    5. Remember the drive letter next to line for the main hard drive; HP_PAVILION or PRESARIO.
    6. To close Diskpart, enter the following: exit
    7. At the command prompt, enter the drive letter followed by a colon (:). For example, H:
    8. At the command prompt, enter the following: cd \windows\system32
    9. At the command prompt, type the following: compact ntldr /u <the drive letter>:\ntldr For example if the drive letter was H, you would type: compact ntldr /u h:\ntldr
    10. Type exit and press Enter .
    11. Click Quit .The error message should be resolved.

    Hard Drive Error during system recovery

    You need to run a hard drive diagnostic disk in dos,(before windows starts) First check with HP, You can also use a program called HDD Regenerator 1.51. This will check the drive for bad sectors, and then you can try and repair them. This way you might
    be able to see some of the data you want. If the sectors that where
    repaired had the operating system on them, you should just get a new drive,(if not under warranty) then after you have a new OS installed on the new drive, you can plug in the old drive and see what you can recover.

    I have an ACER ASPIRE 5720 laptop - it is less than a year old and it is showing the memory is full - the memory is meant to be 32 GB and from what I can see from the programme menus there is less than 4...

    Hi j0shuatsb,
    Acer like many other manufactures seem to design their system to fail or have issues just after their 1 year warranty is up. Like other Microsoft windows operating systems, when you receive an error message that you're memory is full. This does not mean you have run out of RAM = memory. You're notebook can only run a max of 4GB of memory. The error message refers to hard disk drive space. Depending on you're operating system, windows will lock out so much drive space so it can move about. All notebooks also have a hidden partition which holds drivers & programs used in combination for running the system restore.
    This hidden partition can range in size from 2GB up to 4GB.
    This also lessens you're total hard disk drive space. Bottom line is there is nothing wrong with your memory.
    What you need is a larger hard disk drive. Notice the Technical specifications from this link:
    It does not show what size you're SATA hard disk drive is.
    Since you are still in warranty, now would be the time to increase you're drive size. On another note, if you're HDD is the standard 160GB than there is an issue with your current HDD.
    Please run a full system virus scan.
    Suggest you back up all you're personal data on to a DVD & run you're system restore CD including a format to help you regain you're HDD full space. A temporary fix would be to uninstall any non needed programs through Add/Remove programs. This should free up some space. Many Acer programs you do not use at all or need should be the first to go.

    Vista recovery/hard drive

    hi your hard drive is a 250gig when your reinstalling vista it will think that your pc needs to split the hard drives for recovery this is why its done that and because of that it will use a small part of the hard drive for its own mem use so you will lose the total size of the hard drive im running 1000gig and only getting 800 gig for my self this you cannot do anything about .
    the only thing you can do is reinstall your vista program and when on the screen for formatting the hard drive it will say do you want to format the partitions in the box there will be a delet this partition you must delet all the partitions so there is only one left then you must reinstall vista on that one only this will get rid of all the other ones so you sould be left with just 1 hard drive when you start up vista this should put you back on to close to 235gig
    hope this works for you
    all the best thanks
