CONVERT A 512 MB duo/produo/MMC CARD TO 640 MB.
CONVERT A 512 MB duo/produo/MMC CARD TO 640 MB
I guess it works for duo/produo/mmc cards.
Principle:--Your files in duo/produo/MMC is stored in multiple (disk) blocks.
So if you format using 16K block, the space used will be 16K eventhough your file is just 1K.
If you buy DUO/PRO-DUO, it is usually preformatted with 16K block. Therefore a lot of space is wasted as most installed program files are usually less than 2K.
ProCeDure:--
You will need a card reader to do this:-
edit:you can also do it by connecting your phone via usb
1. Connect card reader and copy all your files in the memory card to computer disk.
(Make sure you set the show all/hidden/os files to "on")
2. Do a format of the memory card using command line "format" and use the /A=size option.
Alternative, you can use the Disk Management in Adminstrative Tools to format.
Make sure you select FAT16. For 256MB memory card, smallest block you can use is 4K, 128MB is 2K, 64Mb is 1K and 32MB is 512B.
(Note: You cannot use the phone "format ext.mem" to do this as the format just clear the allocation table and does not change the block size)
3. Copy back all files to memory card.
Now you will find that you will have more space.
I have installed many software to to my 256MB memory card and it is nearly full. After doing above, I got an "extra" 32MB.
For those who have problem with command line format::
Just use the Disk Managament to format
1. Goto Start->control Panel->Administrative Tools->Computer management->Disk management
2. Select your memory card/usb drive. Right-click and select "Format"
3. Select "FAT". Choose Allocation size. For 256Mb MMC select 4K, 128Mb MMC select 2K, 64Mb MMC select 1K and 32Mb MMC select 512B

5 ways to speed up your PC
By following a few simple guidelines, you can maintain your computer and keep it running smoothly. This article discusses how to use the tools available in Windows XP Service Pack 2 (SP2) and Windows Vista to more efficiently maintain your computer and safeguard your privacy when you're online.
Free up disk space
By freeing disk space, you can improve the performance of your computer. The Disk Cleanup tool helps you free up space on your hard disk. The utility identifies files that you can safely delete, and then enables you to choose whether you want to delete some or all of the identified files.
Use Disk Cleanup to:
• Remove temporary Internet files.
• Remove downloaded program files (such as Microsoft ActiveX controls and Java applets).
• Empty the Recycle Bin.
• Remove Windows temporary files.
• Remove optional Windows components that you don't use.
• Remove installed programs that you no longer use.
Tip: Typically, temporary Internet files take the most amount of space because the browser caches each page you visit for faster access later.
To use Disk Cleanup
1. Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Cleanup. If several drives are available, you might be prompted to specify which drive you want to clean.
2. In the Disk Cleanup for dialog box, scroll through the content of the Files to delete list.
3. Clear the check boxes for files that you don't want to delete, and then click OK.
4. When prompted to confirm that you want to delete the specified files, click Yes.
After a few minutes, the process completes and the Disk Cleanup dialog box closes, leaving your computer cleaner and performing better.
Speed up access to data
Disk fragmentation slows the overall performance of your system. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. The response time can be significantly longer.
Disk Defragmenter is a Windows utility that consolidates fragmented files and folders on your computer's hard disk so that each occupies a single space on the disk. With your files stored neatly end-to-end, without fragmentation, reading and writing to the disk speeds up.
When to run Disk Defragmenter
In addition to running Disk Defragmenter at regular intervals—monthly is optimal—there are other times you should run it too, such as when:
• You add a large number of files.
• Your free disk space totals 15 percent or less.
• You install new programs or a new version of Windows.
To use Disk Defragmenter:
1.Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Disk Defragmenter.
2.In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. After the disk is analyzed, a dialog box appears, letting you know whether you should defragment the analyzed drives.
Tip: You should analyze a volume before defragmenting it to get an estimate of how long the defragmentation process will take.
3.To defragment the selected drive or drives, click the Defragment button. Note: In Windows Vista, there is no graphical user interface to demonstrate the progress—but your hard drive is still being defragmented.
After the defragmentation is complete, Disk Defragmenter displays the results.
4.To display detailed information about the defragmented disk or partition, click View Report.
5.To close the View Report dialog box, click Close.
6.To close the Disk Defragmenter utility, click the Close button on the title bar of the window.
Detect and repair disk errors
In addition to running Disk Cleanup and Disk Defragmenter to optimize the performance of your computer, you can check the integrity of the files stored on your hard disk by running the Error Checking utility.
As you use your hard drive, it can develop bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing (such as file saving) difficult, or even impossible. The Error Checking utility scans the hard drive for bad sectors, and scans for file system errors to see whether certain files or folders are misplaced.
If you use your computer daily, you should run this utility once a week to help prevent data loss.
To run the Error Checking utility:
1.Close all open files.
2.Click Start, and then click My Computer.
3.In the My Computer window, right-click the hard disk you want to search for bad sectors, and then click Properties.
4.In the Properties dialog box, click the Tools tab.
5.Click the Check Now button.
6.In the Check Disk dialog box, select the Scan for and attempt recovery of bad sectors check box, and then click Start.
7.If bad sectors are found, choose to fix them.
Tip: Only select the "Automatically fix file system errors" check box if you think that your disk contains bad sectors.
Protect your computer against spyware
Spyware collects personal information without letting you know and without asking for permission. From the Web sites you visit to usernames and passwords, spyware can put you and your confidential information at risk. In addition to privacy concerns, spyware can hamper your computer's performance.
Learn all about ReadyBoost
If you're using Windows Vista, you can use ReadyBoost to speed up your system. A new concept in adding memory to a system, it allows you to use non-volatile flash memory—like a USB flash drive or a memory card—to improve performance without having to add additional memory.

Format USB Drive with NTFS File System.
The advantage of NTFS file system is more security options and fast. Normally USB drive capacity is very small enough that NTFS is not recommended. But, nowadays USB drives are coming with larger capacity also. So we can format USB drive with NTFS to have more security options.
NTFS enabled USB Drives are write-able only on one PC and becomes read only on all other PCs. Hence, we can read and write on our own PC and transfer files to elsewhere without any fear of virus.
In XP, only FAT and FAT32 file systems are available in format options, use the below steps to format in NTFS File System.
1). Insert USB drive in your PC
2). Goto Device Manager (Start>Run>devmgmt.msc)
3). Select Disk Drives and expand
4). Right Click on USB drive and select Properties
5). Goto policies tab and select Optimize for performance and press OK
6). Open My Computer, Click on USB Drive and select Format Opton
Now you can have NTFS option there.

Most commonly used Security Techniques against viruses.
Virus detection and its removal are mode through an antivirus or with some other security program. Different antivirus programs are available in the market and over Internet. The most common and famous security technique against viruses is as under:
Virus Signature/ Virus Definition
Virus signature is a known pattern of code of a code of a virus program; this pattern is used by antivirus program to detect viruses and then to remove these viruses. You should update virus definition continuously by downloading updates from Internet. This ensures that your antivirus is always able to detect changing viruses.
Inoculation
Inoculation file is separate file created and maintained by antivirus program to record information like file size and file creation date. This information later on is used for virus detection and removal.
Quarantine
Quarantine is a separate area on a hard disk. It contains the infected files and folders that cannot be cleared or deleted by antivirus due to some reason, for example sharing violation or unknown virus for that antivirus.
Recovery Disk
Recovery disk is a removable disk that holds un-infected system commands and startup information. In case the boot record of actual hard disk fails, this recovery disk can be used to start the computer. Afterwards an antivirus program can be used to remove the virus.
Un-authorized access
Accessing a computer system without the knowledge or permission of its user is called unauthorized access. It is always recommended to restrict computer resources with the help of usernames and passwords. These are unique combination of characters to identify users and their secret codes respectively.
Firewall
Firewall is a security system consisting of hardware and software to prevent unauthorized access of a network or computer. Big companies use a separate computer firewall software or hardware to protect their date from unauthorized access. Firewall check outgoing and incoming traffic and manage data access to the authorized users only.
Biometric Devices
A biometric device reads personal characteristics like fingerprints hand structure, facial features, and voice recognition to authenticate a user for any further access to a computer system or other peripheral devices. A biometric device translates the personal characteristics into digital code that is matched to already store user data in that system. If the digital data matches with any of the stored data, it gives access to the person. In case of no match, the access is denied.
