完善工作!

通常，當他們的驅動器發生故障時，人需要備份。 所有驅動器某時發生故障-沒有從那真相的逃命。 但有保留好備份的其他原因：

• 總災難，例如毀壞整體計算機和所有附近的備份的火或洪水。
• 故意淘氣，例如刪除重要文件的病毒。
• 一個或更多文件的偶然刪除或修改。

我是肯定的有更多原因，但，如果我們蓋這些我們大概把休息報道。

推進失敗：

驅動器失敗可能通過使用二反射鏡傳動主要避免在配置以RAID 1著名。 RAID意味重複一些獨立驅動，并且有幾個明確定義的水平。 RAID 1是一簡單的comfiguration與確切地總包含同樣信息的二驅動，因此「被反映的期限」。 如果任一驅動發生故障，其他簡單地成為系統的單一驅動并且接管，不用栓。 因為二驅動的可能性立即出故障是非常小的， RAID 1相當很好蓋子問題。 這裡新的計算機使用RAID 1。

總災難：

英特爾E6750把CPU裝箱，并且三個西部數字式320Gb SATA硬盤今天到達了，并且現在所有零件這裡。 我設置了一切除了案件在野餐桌為相片。 在幾張相片外面，我的糖果在背景中喜歡這一個以秋天顏色

然後我下載了在英特爾DP35DP主板展示如何安裝處理器和「熱量解答」的英特爾錄影(風扇+吸熱器)。 在一次演奏錄影以後，我再玩了它并且做了設施，當觀看錄影時。 什麼做棘手是十二個在許多微小的別針在主板插口在CPU薄酥餅必須與聯絡土地的一個相似的數字配比，沒有彎曲任何別針。

And the CPU is just a wafer at this point, not fragile exactly but the motherboard pins are. You are supposed to set the square wafer straight down on the pins without sliding it at all, but I must admit that when I set it down it wasn’t perfectly aligned and it…

I’m struggling with the original precept of this blog: building a new computer, because my Gateway Performance 600 is working so well now. It’s almost eight years old, but it runs a Pentium III processor at 600 MHz and has been upgraded significantly:

1. Added another hard disk to increase total disk capacity from 20 Gb to about 100 Gb.
2. Replaced the original CD RW drive (failed) with a new and better Sony drive.
3. Upgraded from Windows 98 to Windows XP Professional, now SP2 and fully current.
4. Maxed out the memory to 768 Mbytes, comparable to brand-new low-end computers.

It’s not a bad computer, and I’m wavering on the decision to replace it. Money ($1000+) and time are the reasons NOT to replace it. Here are some reasons why I might:

• Quieter. The Performance 600, though not loud, is the loudest thing in the room.
• Faster. I wonder how much. The processors will be ten or twenty times as fast and the disk(s) at least twice

RAID is a computer acronym meaning “Redundant Array of Independent Disks.” Wikipedia. In this case we’re talking about “mirrored” disks, one of the simplest RAID configurations, where two identical disks contain identical data so that one can continue operating if the other fails. Since they contain the same data the second disk doesn’t add any disk capacity, but it does add reliability. Pros:

• The hard disk is MUCH less apt to crash. Only people who have experienced a crash can fully appreciate this.
• Perhaps I can get away with less backup, e.g. only back up the most sensitive data.
• Or, I can buy a THIRD drive and hot-swap it, so the swapped-out drive is the backup.
• I’d enjoy the experience of setting it up and using it.

Cons:

• It’s more expensive: I need two drives, not one, and the motherboard (which manages the drives) costs a little more.
• The drives will make twice as much noise. Hmmm.
• It doesn’t solve ALL backup problems: If I accidentally permanently delete a file, it will be gone on BOTH drives; if lightning hits the computer it could easily take out both drives.

I’m leaning toward…
