memperbaiki flash drive write protected

Banyak yang menyangka Write-Protected pada FD disebabkan oleh Smad-Lock yang sebenarnya adalah fungsi pengamanan flashdisk oleh Smadav, padahal masalah Write-Protected ini sama sekali tidak ada hubungannya dengan Smad-Lock. Masalah ini muncul karena flash disk langsung dicabut tanpa "safely removed hardware"

Solusinya :


Untuk mengatasinya ada beberapa cara, yang bisa berhasil untuk masing2 kasus (tidak untuk setiap kasus). Gak ada salahnya untuk mencoba salah satu dari 5 cara ini Cool .

Cara I.

* Start > Run > type ‘regedit’ then hit 'OK'.
* Browse to the following key:
* My Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlS et\Control\StorageDevicePolicies
* Double click on the string ‘WriteProtect’ and change the ‘Value Data’ box to ‘0’
* You may also need to do this for the strings in any folders called ‘ControlSet***’ e.g.
* My Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\C ontrol\StorageDevicePolicies

Cara II

I am running Windows XP Service Pack 2, so this description applies only in that environment.
Centon's tech support suggested doing the following...

* Start->Settings->Control Panel
* Administrative Tools
* Computer Management
* Under Storage in the left panel, click on Disk Management, wait a minute for Windows to do whatever it is doing,......
* Locate the data stick/thumb drive/whatever-you-want-to-call it, in the right top windowand click on it.
* Right click
* in the popup, click on "Delete Partition" -- make darn sure you are doing this to the RIGHT drive!!!!!
* Right click again, and choose "Create Partition" (or was it format, I forget maybe it was both).

Cara III

Pakai Rapair Utility dari si pembuat flashdisk. Dibawah ini ada link dari HP dan apacer yang banyak dipakai dan berhasil juga untuk berbagai merk.

Maintenance our Computer Performance

If your computer seems slower than it used to be, it probably is. Over time, computers get slower because files become disorganized and resources are consumed by unnecessary software. Fortunately, Your Operating System includes tools to clean up your computer and restore its performance. The five steps in this article will walk you through the use of these tools to tune up your computer with Windows XP or Vista.

Before you do anything, back up your computer. Some of the steps in this article can cause pre-existing but hidden problems to surface, which may keep your computer from starting. A backup allows you to restore your important files in the unlikely event that something does go wrong.

1. Remove unused programs

First, remove programs you don’t use anymore. Programs take up space on your computer, and some run in the background without your knowledge. Removing programs you don’t use can help restore your computer’s performance.

2. Install and run anti-spyware software

Most programs can be removed using the Add or Remove Programs function accessible from Control Panel, but spyware programs are more stubborn. Windows Defender (a free download from Microsoft) or another antispyware program can detect and remove these programs. You should always have an antispyware program installed, because spyware might install itself on your computer without your knowledge. After you install the antispyware program, run it to detect and remove any unwanted programs.

3. Free up wasted space

Removing unused programs is a great way to free up disk space, which will speed up your computer. Another way to find wasted disk space is to use the Disk Cleanup tool.

To run the Disk Cleanup tool

* Click Start, and then click My Computer.
* Right-click Local Disk, and then click Properties.
* On the General tab, click the Disk Cleanup button. Disk Cleanup will spend a few minutes examining your disk.
* The Disk Cleanup dialog box will appear. Select each of the check boxes in the Files to delete list, and then click OK.
* When prompted, click Yes. Disk Cleanup will spend several minutes removing these files, which will provide you with more space.

If you have more than one hard disk drive, repeat this process for each hard disk drive listed in My Computer.

4. Defragment your hard disk drive

Sometimes, a newspaper article skips from the front page to somewhere in the middle of the paper. You have to stop reading the article and flip through the paper to find the page on which it continues. You could read the article much faster if it were printed on a single page.

Files on your computer can either be fragmented, like newspaper articles, or unfragmented, like a book. Over time, more and more files become fragmented. When a file is fragmented, it takes longer for the computer to read it because it has to skip to different sections of the hard disk drive—just like it takes you a few seconds to find a page in the middle of a newspaper.

Defragmentation improves your computer’s performance by reorganizing your files. While fragmentation looks complicated, it’s easy to defragment your computer.

To defragment your computer

* Click Start, and then click My Computer.
* Right-click Local Disk, and then click Properties.
* Click the Tools tab, and then click Defragment Now.
* The Disk Defragmenter appears. Click your hard disk drive, and then click

Defragment.

* Disk Defragmenter will work for at least several minutes, although it might take several hours. When prompted, click Close.

If you have more than one hard disk drive, repeat this process for each hard disk drive listed, starting at step 4.
5. Disconnect unused network connections

If you have, or ever have had, a network with more than one computer, you probably found it useful to share files between the computers by mapping a network drive. Mapping network drives allows one computer to read and write files to another computer’s hard disk drive as if they were directly connected to each other.

The problem with network drives is that Windows XP will attempt to connect to the network drive when it starts up. If the remote computer does not respond immediately, Windows XP will wait, which will slow down your startup time. Additionally, some programs will attempt to connect to the network drive when you browse for files and folders. If you have ever tried to open a file and had to wait several seconds, it is probably because the program was trying to establish a network connection—even if the file you are opening is on your local computer.

To reduce the problem, disconnect any unused drives

* Click Start, and then click My Computer.
* On the Tools menu, click Disconnect Network Drive.
* Select the network drives that you no longer need, and then click OK.

Performing the five steps in this article once a month will help you keep your computer running at peak performance. You can also check my Tips to Speed Up your Computer performance.

10 Tips to speed up your Computer

Tips to speed up your Computer

1. Defrag Disk to Speed Up Access to Data

One of the factors that slow the performance of the computer is disk fragmentation. When files are fragmented, the computer must search the hard disk when the file is opened to piece it back together. To speed up the response time, you should monthly run Disk Defragmenter, a Windows utility that defrags and consolidates fragmented files for quicker computer response.

* Follow Start > All Programs > Accessories > System Tools > Disk Defragmenter
* Click the drives you want to defrag and click Analyze
* Click Defragment

2. Detect and Repair Disk Errors

Over time, your hard disk develops bad sectors. Bad sectors slow down hard disk performance and sometimes make data writing difficult or even impossible. To detect and repair disk errors, Windows has a built-in tool called the Error Checking utility. It’ll search the hard disk for bad sectors and system errors and repair them for faster performance.

* Follow Start > My Computer
* In My Computer right-click the hard disk you want to scan and click Properties
* Click the Tools tab
* Click Check Now
* Select the Scan for and attempt recovery of bad sectors check box
* Click Start

3. Disable Indexing Services

Indexing Services is a little application that uses a lot of CPU. By indexing and updating lists of all the files on the computer, it helps you to do a search for something faster as it scans the index list. But if you know where your files are, you can disable this system service. It won’t do any harm to you machine, whether you search often or not very often.

* Go to Start
* Click Settings
* Click Control Panel
* Double-click Add/Remove Programs
* Click the Add/Remove Window Components
* Uncheck the Indexing services
* Click Next

4. Optimize Display Settings

Windows XP is a looker. But it costs you system resources that are used to display all the visual items and effects. Windows looks fine if you disable most of the settings and leave the following:

* Show shadows under menus
* Show shadows under mouse pointer
* Show translucent selection rectangle
* Use drop shadows for icons labels on the desktop
* Use visual styles on windows and buttons

5. Speedup Folder Browsing

You may have noticed that everytime you open My Computer to browse folders that there is a little delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing speed, you can disable the “Automatically search for network folders and printers” option.

6. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC’s performance. These utilities take up system resources so disabling is a good idea.

* Download and install the Extensible Performance Counter List (http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/exctrlst-o.asp)
* Then select each counter in turn in the ‘Extensible performance counters’ window and clear the ‘performance counters enabled’ checkbox at the bottom button below

7. Optimize Your Pagefile

You can optimize your pagefile. Setting a fixed size to your pagefile saves the operating system from the need to resize the pagefile.

* Right click on My Computer and select Properties
* Select the Advanced tab
* Under Performance choose the Settings button
* Select the Advanced tab again and under Virtual Memory select Change
* Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.

8. Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

* Open Control Panel
* Open Fonts folder
* Move fonts you don’t need to a temporary directory (e.g. C:\FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.

9. Use a Flash Memory to Boost Performance

To improve performance, you need to install additional RAM memory. It’ll let you boot your OS much quicker and run many applications and access data quicker. There is no easiest and more technically elegant way to do it than use eBoostr.

eBoostr is a little program that lets you improve a performance of any computer, powered by Windows XP in much the same way as Vista’s ReadyBoost. With eBoostr, if you have a flash drive, such as a USB flash thumb drive or an SD card, you can use it to make your computer run better. Simply plug in a flash drive through a USB socket and Windows XP will use eBoostr to utilize the flash memory to improve performance.

The product shows the best results for frequently used applications and data, which becomes a great feature for people who are using office programs, graphics applications or developer tools. It’ll surely attract a special attention of laptop owners as laptop upgrade is usually more complicated and laptop hard drives are by definition slower than those of desktops.

10. Perform a Boot Defragment

There’s a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster.

On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently. To make sure that boot defragment is enabled:

* Run the Registry Editor
* Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction
* Set the Enable string value to Y if it is not already set to Y.
* Exit the Registry
* Reboot

Tips Browsing dengan Mozilla Firefox

1. Aktifkan Pipelining
Biasanya browser bekerja dengan mengirimkan permintaan kepada server dan menunggu respon sebelum melanjutkan proses. Pipelining adalah sebuah teknik lebih agresif yang memungkinkan browser untuk mengirimkan beberapa permintaan sekaligus sebelum menerima respon apapun untuk mengurangi waktu yang dibutuhkan untuk mengunduh isi halaman. Untuk mengaktifkan fungsi ini ketik “about:config” pada kotak alamat, klik-ganda pada “network.http.pipelining” dan “network.http.proxy.pipelining” agar nilainya berubah menjadi “true” kemudian klik-ganda pada network.http.pipelining.maxrequest” dan jadikan nilainya “8″.

2. Render dengan Cepat
Situs yang besar dan rumit bisa memakan waktu untuk diunduh. Firefox tidak ingin membuat Anda menunggu, jadi dengan pengaturan standar Firefox akan langsung menampilkan apa yang ia terima setiap 0,12 detik. Walaupun hal ini membuat browser terkesan lebih cepat, rendering ulang yang dilakukan terus menerus meningkatkan waktu total yang dibutuhkan untuk menampilkan halaman, kita dapat mengurangi jumlah rendering ulang untuk meningkatkan kinerja.
Ketik “about:config” dan tekan [ENTER], kemudian klik kanan pada tampilan utama dan kemudian pilih “New > Integer”. Ketik “content.notify.interval” sebagai nama preferensi Anda, klik “ok”, masukkan “500000″ (500 ribu) dan klik “ok” kembali.
Klik kanan lagi pada tampilandan pilih “New > Boolean”. Kali ini buat nilai disebut “content.notify.ontimer” dan atur menjadi “True” untuk menyelesaikan tugas Anda.

3. Loading Lebih Cepat
Jika Anda tidak menggerakkan mouse atau menyentuh keyboard selama 0,75 detik, Firefox akan masuk ke dalam mode “low frequency interrupt” yang artinya interface-nya menjadi kurang responsif tetapi bisa me-load halaman lebih cepat.
Ketik “about:config” dan tekan [ENTER], klik kanan pada tampilan dan pilih “New > Integer”. Ketik “content.switch.threshold”, klik “ok”, masukkan “250000″ (seperempat detik) dan klik “ok” untuk menyelesaikan.

4. Tidak Ada Interupsi
Anda bisa melakukan langkah lebih jauh dengan memberitahu Firefox untuk sama sekali mengabaikan user interface events sampai halaman selesai diunduh. Memang cara ini agak ekstrim karena Firefox bisa menjadi tidak responsif selama beberapa waktu, tetapi tidak ada salahnya untuk dicoba apakah efeknya positif untuk Anda.
Ketik “about:config”, tekan [ENTER] dan klik kanan, pilih “New > Boolean”. Ketik “content.interrupt.parsing”, klik “ok”, atur nilainya menjadi “False” dan klik “ok”.

5. Tingkatkan Ukuran Cache
Ketika berselancar Firefox akan menyimpan gambar dan skrip pada memory cache lokal di mana Anda bisa mempercepat pengambilan data jika mengunjungi situs yang sama kembali. Jika Anda memiliki RAM yang besar (2GB atau lebih), biarkan Firefox berjalan lebih lama sehingga mengunjungi kembali halaman-halaman situs akan lebih cepat, terutama dengan cache yang besar.
Ketik “about:config” dan tekan [ENTER], kemudian klik kanan dan pilih “New > Integer”. Ketik “browser.cache.memory.capacity”, klik “ok”, masukkan “65536″ dan klik “ok”, kemudian “restart” browser untuk mendapatkan cache yang baru dan lebih besar.

6. Aktifkan TraceMonkey
TraceMonkey adalah engine Javascript baru dari Mozilla yang super cepat, dalam beberapa benchmark bahkan mencetak nilai 40x lebih besar dibandingkan versi saat ini. Tracemonkey mungkin saat ini memang dalam tahap pengembangan dan masih sedikit buggy, tetapi jika Anda berkeberatan menggunakan perangkat lunak dalam tahap pengembangan, dapatkan nightly build terbaru dari (ftp://ftp.mozilla.org/pub/firefox/nightly/latest-trunk/). Versi beta pertama Firefox 3.1 juga dijadwalkan untuk dikeluarkan bulan ini juga.
Ketik “about:config” pada kotak alamat dan tekan [ENTER]. Ketik “JIT” pada kotak filter, lalu klik ganda “javascript.options.jit.chrome” dan “javascript.options.jit.content” untuk mengubah nilainya menjadi “true”. Selamat!, kini Anda telah menggunakan engine Javascript mutakhir Firefox.

7. Kompres Data
Jika Anda memiliki koneksi internet lambat, mungkin Anda merasa bahwa Firefox tidak berkinerja baik. Itu tidak sepenuhnya benar! Instalasikan toonel.net dan aplikasi Java ini akan mengambil alih trafik internet Anda melalui server-nya sendiri. Semua data yang melalui server Toonel lalu dikompres sehingga data yang perlu diunduh browser lebih sedikit.
Bahkan, Toonel juga bisa mengompres gambar JPEG, tetapi tentunya berdampak pada penurunan kualitas gambar. Tips ini berguna untuk memotong jumlah data yang dikirim,sangat bermanfaat jika anda memiliki akun internet yang limited bulanannya atau saat menggunakan koneksi internet yang lambat seperti GPRS.

Install Add-On penting seperti :
1. Adblock Plus
Untuk blok banner ataupun alert yang dirasa mengganggu aktifitas browsing kita, dapat didownload disini
2. Faster Fox
Untuk mempercepat kinerja browsing, dan yang paling mantap dari aplikasi ini adalah Auto Loading Next Page, dapat didownload disini
3. Memory Fox
Untuk membatasi penggunana memory kompie saat kita berselancar dengan mozilla (Mozilla kan dikenal sebagai browser Handal tetapi sangat banyak menggunakan memory saat aplikasi dijalankan!!), dapat didownload disini
*dan Add-On lainnya, dapat dlihat sendiri sesuai dengan kebutuhan pengguna browser. ?

Tips Browsing lebih cepat dengan opera dan safari

Untuk OPERA

1. Buka Browser OPERA
2. Pada alamat browser ketikkan opera:config dan kemudian enter
3. Klik Performance
4. Untuk settingan maksimal dari bandwith limit, maka ubah settingan dengan isi berikut:

* Max Connection Server = 10
* Max Connection Total = 64
* Network Buffer Size = 64
* Centang No Connection Keep Alive
* Centang Non-Compliant 100 Server Continue

5. Lalu klik Save, maka akan ada perintah untuk merestart OPERA
6. Tutup OPERA dan buka kembali, rasakan perbedaan speednya!!

Untuk SAFARI

1. Mempercepat User Interface
Menurunkan penggunaan CPU dengan mematikan beamsync di Terminal tulis :
sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -dict deferredUpdates 0

2. Melewati Verifikasi setiap ME-MOUNT File DMG
Saat ingin me-mount file, selalu ada verifikasi terlebih dahulu.
Bila filenya kecil, akan memakan waktu sebentar, tapi jika filenya besar akan memakan waktu yang lama, untuk melewati nya, di Terminal tulis :
sudo defaults write com.apple.frameworks.diskimages skip-verify true.

3. Mempercepat Safari
Anda ingin membuat browser di Mac tersebut menjadi kira-kira 4 lebih cepat, di Terminal tulis :
sudo defaults write.com.apple.Safari WebKitInitial-TimedLayoutDelay –float 0.

4. Menghilangkan Efek Zoom
Selain mempercepat GUI, menghilangkan efek zoom juga mempercepat performa system. Di Terminal tulis :
sudo defaults write.com.apple.finder ZoomRects –boolean NO.

5. Membersihkan Icon Bookmark Safari
Sama seperti sebelumnya, membersihkan icon safari juga bisa mempercepat performa. Di Terminal tulis :
find $HOME/Library/Safari/Icons –type f atime +30 –name “* .cache” –print.
