Cara Memperbaiki Harddisk Yang Rusak
Secara awam mungkin sulit untuk memperbaikinya, tetapi secara teknis harddisk yang rusak bisa diperbaiki, tergantung level kerusakannya.
Cerita dikit tentang Harddisk
Saya membagi harddisk menjadi 4 level, ini berdasarkan riset dan pengalaman saya pribadi selama menangani kerusakan harddisk.
Level 1
Kerusakan yg terjadi pada level ini bisanya disebabkan Bad sector. Untuk menanganinya ada beberapa cara dan variasi percobaan, disesuaikan dengan merk harddisk dan banyaknya bad sector.
Untuk penanganan awal bisa gunakan perintah FORMAT C:/C ( sesuaikan dengan drive yg akan diformat). /C digunakan untuk membersihkan cluster yg rusak. Langkah ke dua jika belum berhasil bisa gunakan program Disk Manager dari masing masing pabrik pembuat Harddisk. Jika belum berhasil juga anda bisa gunakan software HDDREG, silahkan download di internet programnya. Jika belum berhasil coba cara Low Level Format atau Zero File. Jika masih belum bisa, anda bisa lakukan pemotongan sector harddisk yg rusak, dengan cara membaginya dan tidak menggunakan sector yang rusak.
Level 2
Kerusakan yang terjadi pada level 2 adalah Kehilangan Partisi Harddisk dan Data . Ini bisa disebabkan oleh virus atau kesalahan menggunakan program utility. Ada yg perlu diperhatikan dalam mengembalikan Partisi harddisk yang hilang, yaitu kapasitas harddisk dan Jenis File Systemnya. Partisi dengan File System FAT lebih mudah dikembalikan dibanding NTFS atau File System Linux.
Cek terlebih dahulu partisi harddisk dengan menggunakan FDISK atau Disk Manager
Untuk mengembalikannya bisa gunakan software seperti Acronis Disk Director, Handy Recovery, Stellar Phoniex dll.
Untuk mengembalikannya bisa gunakan software seperti Acronis Disk Director, Handy Recovery, Stellar Phoniex dll.
Level 3
Kerusakan yg menyebabkan harddisk terdeteksi di BIOS tetapi tidak bisa digunakan, selalu muncul pesan error pada saat komputer melakukan POST. Biasanya ini disebabkan FIRMWARE dari harddisk tersebut yg bermasalah. Untuk gejala ini banyak terjadi pada harddisk merk Maxtor dengan seri nama-nama Dewa. Untuk memperbaikinya anda bisa download program Firmware dari website merk harddisk tersebut.
Level 4
Kerusakan yang menyebabkan Harddisk benar tidak terdeteksi oleh BIOS dan tidak bisa digunakan lagi. Ini level yang tersulit menurut saya. Karena untuk perbaikannya kita butuh sedikit utak atik perangkat elektronika dan komponen dalamnya. Menganggulangi harddisk yang tidak terdeteksi oleh BIOS banyak cara.
· Mengganti IC pada mainboard Harddisk
· Cara yg extreme harddisk yg rusak bisa dikanibal dengan harddisk yg lain yg keruskan berbeda, bisa dengan cara mengganti maiboardnya atau mengambil IC nya.
·
Cara membuat Internet super Cepat
Browsing Internet dengan kecepatan yang tinggi pasti sangat menyenangkan, berbagai cara dilakukan untuk mempercepat koneksi internet baik menggunakan software agar koneksi internet menjadi lebih cepat maupun menggunakan settingan tertentu yang diklaim bisa mempercepat koneksi internet
Berikut ini adalah beberapa tips yang dapat digunakan untuk mempercepat koneksi internet :
A. Menggubah setting bandwith pada windows (Hanya kami uji pada Windows XP)
Pada dasarnya OS windows sudah membatasi bandwidth untuk koneksi internet sebanyak 20% dari total bandwidth yang seharusnya bisa maksimal, jika netter ingin menambah bandwidth internet supaya koneksinya terasa lebih cepat dan kencang bisa dengan cara mengurangi atau mengosongkan batasan bandwidth tersebut supaya pada Windows kita bisa maksimal dalam menggunakan bandwidth yang sudah ada.
Ikuti petunjuknya seperti dibawah ini :
1. Klik Start
2. Klik Run
3. Ketik gpedit.msc
4. Kemudian klik Ok
5. Setelah masuk klik (buka) Administrative Templates
6. Kemudian klik (buka) Network
7. Setelah terbuka klik QoS Packet scheduler
8. Kemudian klik Limit Reservable Bandwidth
9. Dan setelah terbuka ubah setting menjadi Enable
10. Kemudian ubah Bandwidth Limitnya menjadi 0
11. Klik Apply, dan terus Ok
12. Kemudian keluar dan Restart komputer
2. Klik Run
3. Ketik gpedit.msc
4. Kemudian klik Ok
5. Setelah masuk klik (buka) Administrative Templates
6. Kemudian klik (buka) Network
7. Setelah terbuka klik QoS Packet scheduler
8. Kemudian klik Limit Reservable Bandwidth
9. Dan setelah terbuka ubah setting menjadi Enable
10. Kemudian ubah Bandwidth Limitnya menjadi 0
11. Klik Apply, dan terus Ok
12. Kemudian keluar dan Restart komputer
B. Pakai browser Google Chrome atau Apple Safari
Versi terbaru dari browser Chrome dan Safari sangatlah cepat bila dibandingkan dengan Firefox ataupun Internet Explorer (sudah dicoba dan terbukti memang jauh lebih cepat). Saran saya pakailah Google Chrome karena selain cepat, Chrome lebih aman dibanding dengan Safari, walau dalam beberapa hal Safari kadang lebih cepat dari Chrome.
Kalau netter sudah terbiasa memakai Firefox dan tidak ingin beralih ke browser lagi, bisa tambahkan Add-on “Adblock” untuk memblok iklan, gambar, dan flash yang aktif. Ada beberapa Add-on lagi dari Firefox seperti NoScript yang bisa mempercepat akses internet, tapi sayangnya kalau kebanyakan Add-on justru, kadang malah memperlambat akses dari browser Firefox sendiri.
C. Perbesar cache browser hingga 5% dari kapasitas Harddisk atau 1 – 2 GB
Cara ini terbukti efektif untuk mempercepat akses browser. Logikanya adalah browser tidak perlu tiap kali loading gambar dan tetek bengeknya segala setiap kali berkunjung ke situs yang sudah pernah dikunjungi, karena kalau situs sudah pernah dikunjungi akan otomatis di-cache oleh browser.
