Cara Mengubah Drive Letter Partisi Harddisk

Cara Mengubah Drive Letter Partisi Harddisk. Ini adalah masalah yang saya hadapi saat menginstall sistem operasi Windows Vista ulang atau recovery, setelah selesai, urutan partisi hardisk menjadi tidak seperti sebelumnya, dan drive DVD-RW tidak berada di akhir urutan.

Walaupun hal ini sebenarnya tidak berpengaruh terhadap kinerja komputer, hanya saja biasanya sering membuat bingung. Hal itu disebabkan ada partisi yang belum di format ketika menginstall windows, sampai selesai installasi. Jika menggunakan aplikasi pihak ketika mungkin bisa menggunakan Partition Manager dan sejenisnya, tetapi sebenarnya Windows (XP maupun Vista) sudah memiliki fasilitas ini, termasuk memformat partisi yang tidak terdeteksi oleh Windows Explorer.


Cara Mengubah Drive Letter Partisi Harddisk Sebagai berikut :

1. Buka Control Panel
2. Pilih Administrative Tools
3. Pilih Computer Management
4. Di bagian storage, pilih Disk Management
5. Akan ditampilkan formasi partisi hardisk kita. Termasuk partisi yang belum diformat
6. Untuk mengubah Drive Letter, klik kanan partisi yang diinginkan atau CD-ROM dan pilih menu Change Drive Letter and paths
7. Di Window yang tampil pilih change, dan ganti nama drive yang tersedia

Disini perlu juga Trik komputer, untuk mengubah drive letter-nya karena kalau drive letter sudah dipakai partisi lain kita tak bisa mengubahnya langsung. Misal kita ingin mengganti drive D: menjadi E: (misal ada 3 partisi C:, D:, E:), maka sebelum mengganti D: menjadi E: kita harus ubah dulu E: ke nama lain misal Z:, baru kita ubah D: ke E:, setelah itu baru Z: kita ubah ke E:. Intinya tukar nama yang dilakukan harus melewati proses ganti nama salah satu drive yang akan ditukar namanya (drive letter-nya).

Fasilitas ini juga berguna ketika kita memasang USB flash disk, kemudian memasang kamera. Kadangkala kamera kita tidak terdeteksi di Windows Explorer. Biasanya disebabkan drive letter-nya dipakai oleh Flashdisk ada kamera yang tidak bisa ditampilkan ketika sudah ada Flash disk atau USB port sedang dipakai alat lain). Cara mengatasi hal ini, ubah saja drive letter USB tersebut ke huruf lain, kemudian kembali masukkan kabel kamera ke port USB.

Pengertian Search Engine Optimization (SEO)

Optimisasi mesin pencari (Search Engine Optimization, biasa disingkat SEO) adalah serangkaian proses yang dilakukan secara sistematis yang bertujuan untuk meningkatkan volume dan kualitas trafik kunjungan melalui mesin pencari menuju situs web tertentu dengan memanfaatkan mekanisme kerja atau algoritma mesin pencari tersebut. Tujuan dari SEO adalah menempatkan sebuah situs web pada posisi teratas, atau setidaknya halaman pertama hasil pencarian berdasarkan kata kunci tertentu yang ditargetkan. Secara logis, situs web yang menempati posisi teratas pada hasil pencarian memiliki peluang lebih besar untuk mendapatkan pengunjung.

Pengertian Search Engine Optimization, SEO adalah seperangkat metode yang berkonsentrasi pada peningkatan peringkat website dalam daftar mesin pencari. Demikian pula, SEO juga dapat dianggap sebagai bagian dari pemasaran mesin pencari. Istilah ini juga merujuk pada sebuah industri konsultan yang melaksanakan proyek-proyek optimasi mewakili situs klien.Search Engine Optimization metode dapat dikategorikan sebagai White Hat SEOs dan Black Hat SEOs. Mesin pencari untuk membangun dan meningkatkan kualitas konten situs sering menyetujui metode White Hat SEO. Namun,  Back Hat SEO sering menggunakan metode dan trik seperti Cloaking dan Spamdexing. Bahkan, ada argumen dimana White Hatters tuduhan bahwa metode Black Hat adalah usaha untuk memanipulasi peringkat pencarian tidak adil, dan Blaclk Hatters Counter bahwa SEO semua adalah usaha untuk memanipulasi peringkat.

Sejalan dengan makin berkembangnya pemanfaatan jaringan internet sebagai media bisnis, kebutuhan atas SEO juga semakin meningkat. Berada pada posisi teratas hasil pencarian akan meningkatkan peluang sebuah perusahaan pemasaran berbasis web untuk mendapatkan pelanggan baru. Peluang ini dimanfaatkan sejumlah pihak untuk menawarkan jasa optimisasi mesin pencari bagi perusahaan-perusahaan yang memiliki basis usaha di internet.

Tool Khusus Untuk PC Yang Terinfeksi Virus

Ketika virus yang bagus dan kuat menginfeksi komputer, kebanyakan dari virus tersebut akan mendisable berjalannya Task Manager (taskmgr.exe), Registry Editor (regedit.exe), Command Prompt (cmd.exe), System Configuration Utility (msconfig.exe), folder option dan menyembunyikan Run dari Start Menu. Alasannya adalah karena kemungkinan para user yang mahir komputer dapat me-remove virus dengan menggunakan program-program tsb.

Ketika kita tidak bisa menjalankan Task Manager, kita tidak bisa mematikan proses virus. Paling tidak kita bisa menggunakan perintah taskkill pada Command Prompt, tapi sekali lagi kita tidak bisa melakukan itu jika CMD pun telah di disable, mungkin kita bisa menjalankan msconfig untuk menghentikan virus dari auto startup, tapi tetap tidak bisa jika virus mendisablenya. Bagi para user advance yang mempunyai basic registry dan dengan cara itu mereka bisa secara manual me-remove virus dari list auto start up, tapi tetap tidak akan bisa juga jika file registry (regedit.exe) didisable. Begitu pula folder option dan proses-proses lainnya yang didisable untuk memperpanjang kinerja virus itu sendiri.

Jadi untuk hal-hal yang bersifat darurat, ada tool-tool pengganti yang bisa digunakan ketika tools asli windows banyak yang didisable, dari 12 tool yang akan sedikit dibahas disini hanyalah 6, yaitu :

1. Process Explorer sebagai pengganti Task Manager (taskmgr.exe)

Task Manager sangatlah penting karena dari situ kita bisa melihat hampir seluruh proses

Yang sedang berjalan di windows, begitu juga jumlah memory yang terpakai dan CPU yang terpakai. Jika kita menemukan sesuatu yang mencurigakan disitu, kita bisa akhiri prosesnya (terminating). Jika kita tidak bisa menggunakan Task Manager dan mendapatkan pesan “Task Manager has been disabled by your administrator”, kita bisa menggunakan Process Explorer. Tool ini portable kita bisa menyimpannya di usb drive.

2. RegAlyzer sebagai pengganti Registry Editor (regedit.exe)

Tanpa kemampuan untuk mengakses registry Windows, kita tidak bisa secar manual membuat perubahan sama sekali, tidak bisa mengimpor file registry (REG files). Ketika virus telah mendisable regedit kita dapat menemukan sebuah pesan ““Registry editing has been disabled by your administrator”, ketika kita menjalankannya. Alternatif yang bagus adalah dengan menggunakan RegAlyzer, dikembangkan oleh Spybot. RegAlyzer membutuhkan isntalasi, tapi kita bisa copy semua folder yang talh jadi ke usb drive dan menjalakannya secara portable.

3. GS sebagai pengganti Command Prompt (cmd.exe)

Command prompt adalah tool yang powerful yang mendukung banyak perintah (commands) ketika kita menemukan sesuatu yang tidak bisa dilakukan di windows. Jika kita menjalankan command prompt dan mendapatkan pesan “The command prompt has been disabled by your administrator. Press any key to continue”, kita dapat menggunakan GS. GS adalah pengganti cmd, GS freeware dan portable.

4. Run Dialog Replacement 1.0 sebagai pengganti Kotak Dialog Run

Beberapa virus juga menghilangkan perintah run dari Start Menu dan tidaklah mudah untuk memunculkannya. Walaupun hal ini tidak begitu penting. Tapi Run memudahkan kita untuk melakukan perintah yang penting. Run Dialog Replacement V.1.0 cukup kecil, hanya berukuran 48 kb dan juga portable. Gunakan perintah Run dengan hanya menekan ctrl+R.

5. Autoruns sebagai penganti System Configuration Utility (msconfig.exe)

Msconfig adalah tempat pertam kali saya untuk melakukan pemeriksaan ketika komputer jika computer terinfeksi virus. Jika kita menjalankan msconfig dan klik tab startup, maka akan terlihat seluruh program yang akan berjalan ketika windows baru start. Para pembuat virus sangat awas mereka biasanya mendelete file original msconfig atu mengganti lokasi aslinya dari registry windows. Jika kita menemukan pesan “Windows cannot find ‘msconfig’. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.” ketika mengakses msconfig. Alternatid yan bagus untuk itu adalah tool Autoruns, satu publish dengan Process Explorer. Autoruns mempunyai banyak keterangan dari lokasi berjalannya suatu proses dari startup, menunjukkan program yang megnkonfigurasi ketika system booting dan login.

6. FreeCommander sebagai pengganti Folder Option

Saya telah banyak mencoba memanage file dan kebanyakan dari padanya merubah "show hidden files or hide protected opering system" dari setingannya pada windows. Jika virus tetap aktif di memory, maka masih bisa merubah setting untuk mendisable dari melihat file-file yang di sembunyikan (hidden) dan file system. FreeCommander adalah tool yang dapat melakukan aksi seperti folder option, tool ini portable. Kita dapat mengextract semua filenya ke usb drive.

Tool yang lain mempunyai fungsi yang hampir sama, dintaranya yaitu:

- autorun management application

- Proccess Master

- Sohand Removal tool

- Files And Folders Reset attrebiutes

Nah itulah beberapa Tool Khusus Untuk PC Yang Terinfeksi Virus. Semoga bermanfaat.
