| Posted: 27 Feb 2011 01:31 AM PST  Jasakom - Banyak orang yang tidak berani melakukan "Quick Format" dengan alasan "kurang bersih", "agar harddisk lebih awet","agar lebih sempurna" dan alasan lainnya sehingga selalu melakukan format biasa. Masalahnya adalah melakukan format biasa pada harddisk IDE ataupun SATA yang berukuran ratusan GB, bisa memakan waktu berjam-jam. Ketika hendak melakukan format terhadap sebuah disk, Windows memberikan Anda pilihan yang lebih menyenangkan yaitu "Quict Format" namun pilihan ini seringkali tidak digunakan. Alasannya klasik, kurang bersih ! Apa yang "kurang bersih" ? apa perbedaan antara format biasa dan quick format ? Benarkah agar harddisk benar-benar "bersih" harus dilakukan format biasa ? Bagaimana bila saya telah melakukan "Quick format", apakah harus melakukan format ulang agar harddisk saya lebih awet ? Format biasa dan quick format sebenarnya melakukan hal yang sama persis dan hanya ada satu perbedaan diantara keduanya yaitu pengecekan terhadap sektor. Pada format biasa, windows akan melakukan proses pengecekan terhadap seluruh isi harddisk anda terhadap kemungkinan kerusakan pada harddisk dan menandai lokasi yang rusak tersebut agar komputer tidak menggunakannya untuk menyimpan file. Bila lokasi yang rusak tersebut digunakan untuk menyimpan file, tentunya akan menyebabkan file tersebut tidak bisa diambil kembali. Tahapan pengecekan terhadap setiap sektor yang ada didalam harddisk inilah yang menyebabkan kenapa proses format biasa memakan waktu yang begitu lama. Lalu apakah benar format biasa membuat harddisk anda lebih segar dan lebih bersih ? Tidak sama sekali ! ini adalah pandangan yang sama sekali keliru karena seperti yang telah kami katakan sebelumnya, proses format biasa dan quick format itu sama. Lalu bagaimana dengan pandangan yang mengatakan bahwa format biasa membuat harddisk lebih awet ? Setiap alat elektronik, apapun itu selalu memiliki apa yang dinamakan dengan MTBF (Mean time between failures). MTBF secara umum bisa diartikan sebagai "umur hidup" sebuah peralatan elektronik, artinya semakin Anda menggunakan sebuah peralatan, umurnya akan semakin pendek. Dengan format biasa, selain harddisk akan digunakan jauh lebih lama, harddisk juga akan bekerja jauh lebih berat sehingga pernyataan bahwa harddisk akan lebih awet tentu saja tidak benar bahkan salah sama sekali karena yang terjadi justru kebalikannya. Apakah Format Biasa Masih diperlukan ? Tentu saja ! dan masih sangat penting untuk dilakukan. Data Anda tentu jauh lebih penting daripada harddisk yang harganya tidak seberapa karena itu, melakukan pengecekan terhadap kemungkinan terjadinya kerusakan harddisk pada lokasi tertentu pantas untuk dilakukan namun tidak harus dilakukan pada saat format. Anda bisa melakukan pengecekan setiap saat terhadap kemungkinan terjadinya kerusakan fisik pada harddisk Anda dengan menggunakan perintah chkdsk /r. Perintah ini akan melakukan pengecekan terhadap kemungkinan terjadinya kerusakan pada harddisk seperti yang dilakukan pada saat format biasa. Jika Anda telah melakukan format biasa atau pengecekan harddisk dengan perintah chkdsk/r, Anda tidak harus melakukannya lagi dalam waktu dekat apalagi melakukan format biasa berulang kali karena hal tersebut hanya akan menghabiskan waktu Anda yang berharga...             |
| Apple hugely upgrades MacBook Pro Posted: 27 Feb 2011 01:06 AM PST  Apple has finally updated the MacBook Pro lineup.

| Posted: 27 Feb 2011 01:03 AM PST Apple iPhone 4 and HTC EVO 4G are by far the two most exciting smartphones that money can buy to date. And in many ways they are very similar: both have big full-phone-size touchscreens, smart operating software, lots of free or cheap applications, high resolution photography and video recording, video call capabilities, etc. I imagine for a consumer who is not technically sophisticated it will be an absolute guess whether iPhone 4 or EVO 4G will work better for him or her. But yet somehow Apple and HTC have managed to design two completely different smartphones despite playing on the same field by the same rules. So I decided to try and look at both of them as if there was no such criteria as price, carrier, data plan, or even quality issues iPhone 4 and EVO 4G users have already experienced. HTC EVO 4G  First up the EVO. It has been around a bit longer than the iPhone and it's a first ever mobile phone to support 4G network. In plain English it means your Internet connection will be faster when Wi-Fi is out of access – exactly what iPhone 4 owners will be jealous of considering video calling (iPhone 4 can only do FaceTime, as they call it, on Wi-Fi). In hardware respect EVO 4G is brimmed up with latest technology (check out the specification list below). One of the few things one might not be completely satisfied with is the display. Yes, at its 4.3 inches it is quite big, but it is a standard LCD technology which compared with AMOLED or indeed high pixel density Retina opposition doesn't perform just as good. On personal note, I also don't like EVO 4G's shape at the back of it. iPhone 4 is flat whole round witch most people like better – it feels nicer in a pocket and in hand as well. Still, half of the reason to buy EVO 4G is Android. At the moment of writing it is shipped with Android 2.1 but 2.2 Froyo update is cooking as we speak. And that is very important for the EVO 4G. You'll expect this kind of smartphone to offer some of the best Internet experience in the market. It does. Android claims to have the fastest mobile browser whilst along with further enhancements Froyo quadruples Flash performance. Mind you that Safari doesn't support Flash at all. Plus Android has true multitasking but will run its battery flat faster. All things considered including the audience that has actually bought HTC EVO 4G I'd recommend it to someone who captures and enjoys the sweet spot of the latest technology and extremely capable operating system. If you are not among them but you like the HTC EVO 4G, don't worry – it will still fit you well. HTC EVO 4G specifications: Processor: Qualcomm Snapdragon @ 1GHz RAM: 512MB Operating system: Android 2.1 (2.2 update this year) Display: 4.3" TFT LCD, 800 × 480 resolution Storage memory: 8GB, up to 32GB w/microSD Rear camera: 8 megapixel Front camera: 1.3 megapixel Video recording: 720p @ 30fps Battery capacity: 1500mAh Wi-Fi: 802.11 b/g (/n w/Android 2.2) Cellular network: 4G Size: 4.8 × 2.6 × 0.5 Weight: 6oz Apple iPhone 4  This, in my opinion, is the most charismatic smartphone if you accept this kind of description for a device. It certainly has the X factor that makes you take it out of your pocket just to let the others see it. EVO 4G will never be able to pull that off anytime anywhere. In front of tech enthusiasts – yes, absolutely, but that's almost about it. Another feature peculiar to the all of the iPhones so far is that somehow they remain modern and up-to-date through all their lifetime and right up to the moment when the next-gen model is presented. I mean this time last year we could hardly wait for HTC Hero to come out. But after it did, it didn't stay long in our hearts. iPhone 3G S on the other hand kept its positions till June. Even now I can tell the same will happen to the iPhone 4 – everything coming out next year or so will be put up against it. Should this affect your choice? – Yes, at least at some degree. It receives that kind of treatment for a reason. iOS 4 and hardware that runs it are not any less capable than the EVO's and Apple app store does offer more apps, but unfortunately iPhone 4 also has a problem or two. As I said above Safari doesn't support Flash and the operating system itself doesn't have full-flesh multitasking but runs a number of services instead. However, running services in the background rather than processes improves greatly on battery life while keeping usability basically on the same level. That's a small price to pay for some features you get with the iPhone 4 that others can't match. One of them is, of course, Retina display. Enlarging pixel density is really a path to follow for all upcoming devices because physically they cannot get much bigger while display resolution has to grow. All in all if you for some reason didn't like HTC EVO 4G you will almost certainly like iPhone 4, but it won't necessarily work vice versa. Apple iPhone 4 specifications: Processor: Apple A4 RAM: 512MB Operating system: iOS 4 Display: 3.5" IPS LCD, 960 × 640 resolution Storage memory: 16GB/32GB Rear camera: 5 megapixel Front camera: VGA Video recording: 720p @ 30fps Battery capacity: 1420mAh Wi-Fi: 802.11 b/g/n Cellular network: 3G Size: 4.5 × 2.31 × 0.37 Weight: 4.8oz        |
| Ricoh GXR Digital Camera Review Posted: 27 Feb 2011 12:57 AM PST  Ricoh GXR is an interchangeable unit camera system in which lenses are changed by using a slide-in mount system to attach camera units to the body. The camera also features Built-in flash and accessory shoe, DMI connecto and a 3.0-inch 920,000 pixels transparent LCD. The camera measures 114 x 70 x 29mm (4.5 x 2.7 x 1.1 in) and weighs 160g (5.6 oz).  The GXR launches with two very different optional lens modules. Although the body is very thin, how pocketable the camera is depends entirely on the lens module mounted: the S10 zoom unit maintains the low profile when not in use (it collapses when powered down) but the A12 prime is a fairly large unit.        |
| Posted: 27 Feb 2011 12:45 AM PST  The Samsung N150 is the latest miniature notebook that promises an improved battery life and basic computing on the cheap. The Samsung N150, rather excitingly, ditches the stalwart Intel Atom N270 CPU for a newer, faster, more efficient processor known as the Atom N450. The N150 is available from PC World for £280.  The Samsung N150 netbook gives you value without compromise. The non-glare 10.1″ screen gives you plenty of room, while a 3-in-1 memory card slot and 3 USB 2.0 ports make it easy to connect a digital camera, printer and more. At a scant 2.7 lbs, you can pick up and go at a moment's notice, and the battery (up to 7 hours) is good for all day        |
