硬碟再生器是一個可令硬碟起死回生的特殊軟體，它可以清除硬碟表面的物理壞軌，不是隱藏，而是真正的修復壞軌！
工作原理：差不多 60%以上的硬碟壞軌是由於硬碟表面磁化錯誤造成的，用軟體根據特殊序列的演算法產生高低信號，將對受損的盤面進行轉換，即使低級格式化也做不了這個工作。
優勢：通過將磁性逆轉來使壞軌再生。如果您的硬碟有壞軌，不僅影響使用，而且還有可能造成所存儲的訊息遺失，硬碟再生器將使您的硬碟得到再生（差不多 60%的受損硬碟是可以修復的）。結果是，不可讀取的受損訊息被修復，現有的訊息不會受到影響。
最低系統環境：針對 Windows作業系統做了優化，在 Windows XP/Vista 環境下可以直接開始修復過程。在其它作業系統下使用，您需要建立一張可引導的修復盤。
如何使用：開啟硬碟再生器後就可以開始修復，建立修復引導軟式磁碟機。如果您使用的是非註冊版本，您就只能修復找到的第一個壞軌。未註冊的展示版本的主要 目的是顯示出已註冊完整版能夠修復的壞軌訊息，這個訊息在修復過程結束後會顯示在螢幕上，註冊版會仔細地檢測硬碟盤面並且修復所有找到的壞軌。
重要提示：
硬碟再生器直接工作於硬體底層，不會影響硬碟的邏輯結構。即使您的硬碟已經得到修復，檔案系統可能仍會保持著早先所標記的壞軌訊息，如果您想清除這些早先的壞軌訊息，可以用PQ（分區魔術師）之類的軟體對硬碟重新分區。

MHDD 磁碟修護程式
硬碟掃瞄超快速：MHDD
硬碟讀取、運作有問題時應該怎麼辦呢？
讓 MHDD 來幫你處理這些問題吧！
超快的掃瞄速度絕對讓你眼睛為之一亮，不必再耗費數小時除錯，另外還有修復壞軌、低階清除動作功能。
就算硬碟過了保固期，也可以藉由 MHDD 的幫助來讓硬碟重獲新生。
相信許多使用者都有硬碟損壞的經驗，如果產品還在保固期內，當然是送回交由廠商來處理，但是萬一已經過了保固了應該怎麼辦呢？
難道就直接放棄它嗎？
當然不是，你可以藉由 MHDD 的幫助來讓他重獲新生。
MHDD 是一款由俄羅斯人所開發的免費硬碟實體掃瞄維護程式，比起一般的硬碟表層掃瞄， MHDD 有相當令人激賞的掃瞄速度，讓使用者不再需要花費數個小時來除錯，只需幾十分鐘，一顆 80G 大小的硬碟就可以掃瞄完成，且 MHDD 還能夠幫使用者修復壞軌，讓使用者能夠繼續延續該硬碟的生命餘光。
此外， MHDD 還能夠對硬碟進行低階清除的動作，讓想要賣掉硬碟的你不必擔心硬碟中的資料被接手的買家回復盜用的困擾喔！
官方所提供的 MHDD 可分為磁片版與光碟版兩種，能夠直接至官方網站上下載光碟影像檔，並且透過燒錄機燒錄成光碟後使用。

FreeBSD的 current , stable , release 版本, 有何差別?
current 就是還在開發中的，每天都會有新的程式碼加入world , kernel中，會是production release的下一版，也就是還在開發中的版本，通常都是心臟很強的系統管理者在用的，或是有在開發world , kernel的core team成員在用的版本，不保證功能都會正常，也不保證穩定性，這邊指的版本是大的版本編號，例如從7到8這樣的大版號跳躍
stable 並不是所謂的穩定版，它只是目前的release版本到下一個release版本之間的版本，每天都會有新功能加進來，不過和current 比起來，算是比較穩定的，下一個release版本的新功能會在stable先做測試，新功能測試的差不多之後就會變成新的release，適合喜歡用新功能，可是又怕不穩的人，或是自己的工作站，自己的desktop這類的用途，這邊指的版本是小的版本編號，例如從7.0到7.1這樣的小版號跳躍
release 顧名思義就是發行版，release只要發行了之後，程式碼就不會再做更動了，只會有安全性修正的patch會加進來，比較適合做為server用途，追求穩定的時候就適合使用release版搭配security patch

Flash 9 for FreeBSD 7.1
Step 1: Enable Linux compatibility and linprocfs
Add linux_enable="YES" to /etc/rc.conf. Add compat.linux.osrelease=2.6.16 to /etc/sysctl.conf. Add OVERRIDE_LINUX_BASE_PORT=f8 to /etc/make.conf. Add this line to /etc/fstab:
linproc /usr/compat/linux/proc linprocfs rw 0 0
Then run these commands:
mkdir -p /usr/compat/linux/proc
mount /usr/compat/linux/proc
/etc/rc.d/abi start
/etc/rc.d/sysctl start
Step 2: Update ports and install all the needed software
You will now need to install the following ports and their dependencies:
cd /usr/ports/emulators/linux_base-f8 && make install clean
cd /usr/ports/www/linux-flashplugin9 && make install clean
( or cd /usr/ports/www/linux-f8-flashplugin10 && make install clean )
cd /usr/ports/www/nspluginwrapper && make install clean
Follow the nspluginwrapper instructions to enable all available plugins:
# nspluginwrapper -v -a -i

How to Create a DOS - bootable USB Memory Key within Windows
Method 1
If you do not have a floppy disk drive, you may want to create a bootable USB memory key which will allow you to boot into a pure DOS environment. This can be very useful if you want to flash your BIOS. Here is a step by step procedure on how to perform this operation.
NOTE: Your computer must support booting from a USB device in order to boot from the USB Memory Key.
Step 1 - Download and install the Windows based HP USB Disk Format Tool.
Step 2 - Download the Windows 98 system files from HERE. This is a zip file that contains all of the system files that you will need. Create a new folder and extract these files into the folder that you just created. Make sure that you preserve the directory structure.
Step 3 - Insert the USB Memory Key into the USB port of your computer.
Step 4 - Launch the HP format tool program.
Step 5 - Under the file system drop down list, select FAT32. This is important to do correctly.
Step 6 - Check the box next to Create a DOS startup disk.
Select "using DOS system files located at:" Then click on the square box with 3 dots on it.
Step 7 - Browse to the folder that you extracted the Win98 system files and then click on the OK button.
Step 8 - Now click the Start button.
Step 9 - You will receive a warning message. Make sure you have the USB memory key selected. If you are sure, then click the Yes button.
Step 10 - Your USB memory key is now being formated and the DOS system files will be copied onto it.
Once the program has completed the operation, click on the Close button.
You now have a bootable USB memory key.
On the USB memory key, you will see COMMAND.EXE, IO.SYS and MSDOS.SYS. These are the basic Win98 system files.
If you want to have CDROM support when you boot from your USB memory key, copy these files, including the CDROM folder to the memory key. These files are the ones that you extracted earlier to a folder.
If you copy all of these files to the memory key, you will have mouse support for any DOS program that support this feature.
You will also have many other DOS utilities that are very useful.
Method 2
Executing bootflashdos
No matter which method you applied. Don't forget to change BIOS setting. In BIOS->Hard Disk Boot Priority, select USB-HDD01 XXXXX as priority 1.
