2. Buffer “under run” at sector once an image file is generated , CD writing is a real process that must run constantly at the selected recording speed without interruptions
a. The CD recorder’s buffer is constantly filled with data from the hard drive waiting to be written.This buffering action ensures that small slow downs in the flow of data from computer do not interrupt writing .
b. The above message indicates that the flow of data from hard disk to CD recorder was interrupted .
c. To avoid buffer under runs you should remove as much as processing load as possible from the system.
Top

3. The currently selected source CD-Rom drive or CD-Recorder cannot read audio in digital format.
a. This is more a warning than a fault.
b. Reading audio tracks in “digital format” is not the same as playing the music, and few CD-Rom drives are able to read audio tracks in digital format .
Top

4. Destination disc is smaller than the source disc.
a. The errors commonly occurs when you are trying to duplicate an existing CD to CD-R.
b. There is not enough room on the recordable CD to copy the source CD. Try recording to a blank CD.Use 74 minutes media instead of 60 minute media . Some CDs cannot be copied because of the TOC(Table of Content) overheads in CD-recorders , and also because of the calibration zone overhead.
Top

5. Disc is Write-protected.
a. You are attempting to write a disc that has already been closed .
b. Use a fresh blank disc for writing.
Top

6. Error 220-01-xx-xx

Top

12. Write emergency
a. This error occurs if the drive is interrupted during a write action .
b. It is commonly seen when writing red book audio , but it can also occur with data.
c. For example , one typical reason for a write emergency is dust particles that cause the laser to jump off the track.
Top

13. The CD-R is recognized by Windows, but it will not function as a normal CD-Rom drive.
a. The drive appears normally in the windows device manager .
b. The drive that is operating the CD-R drive might not allow the drive to function as a normal CD-Rom reader.
c. For Example, this is known problem with the Philips CDD 2000 CD-R, check to see if an updated windows 95 CD-R driver is available to overcome this limitation.
d. If not, you might need to replace the CD-R drive with an upgraded model whose drivers do support CD-Rom type functionality
Top

14. You cannot read CD-R (gold) discs in some ordinary CD-Rom drives.
a. Laser calibration plays a big role. Some CD-Rom drive lasers are not calibrated to read recordable discs.
b. If your CD-Rom drive reads mass produced CDs, but not recordable CDs, check with its manufacturer to determine whether laser calibration is the problem.
c. The CD-R authoring software can be a problem.A good way to check whether incompatibility problem lies with the originating software is to test the same gold disc on several CD-Rom drives.
d. If one drive is capable of reading the gold disc back correctly, chances are that the problem was not in the recording process.

Tricks

2008-12-25T17:44:00.000-08:00

1. Removing extra fonts for speed
2. Increse Bandwidth By 20% (XP Users)
3. Increase the speed of your menus
4. Creating a desktop shortcut for locking your computer.
5. Open command prompt for current folder path by right click.
6. To enable Transfer mode to DMA.
7. To turn on clear type font.
8. Enable/Disable Boot Defrag.
9. Archiving Messages in Yahoo Messenger.

1. Removing extra fonts for speed
Windows XP has over 250 different font variations that it loads for use when the system boots up. Of these 250 variations, only a handful are used on a regular basis. Most likely, you really only use the core Windows fonts, such as Tahoma,Times New Roman, Arial, Verdana,Trebuchet, and MS Sans Serif. Simply put, loading a lot of fonts will take more time, because the system has to load and index each font. Thankfully, there is a very simple answer to this: Just remove the fonts that you do not use from your font directory. The best way is to move the unused fonts to a separate folder on your system so that if you ever want to use one of those extra fonts again, you just have to copy it back to the fonts folder. Part II — Increasing Your System’s Performance
Recommended Fonts to Keep

Font Name : Reason
Verdana: Often used on Web pages and applications
Arial : Often used within applications such as Outlook Trebuchet Used in the Windows interface on the Title Bar
Tahoma : Used in the Windows interface on the Menu Bar as well as in many applications and Web pages
Times New Roman : The default font for Web pages as well as applications such as Word
MS Sans Serif : Used in some applications and Web pages

Control panel-font-(select font and delete)
Top

2. Increse Bandwidth By 20% (XP Users)
Well if you are tired of the lessened speed of your internet then here is the better approach to increse the bandwidth.Actually the Xp reserves the bandwidth for Quality of Service(QOS) which works for downloading of the xp updates in parallel with the motion of the normal course internet. If we try to manage the Qos then we can augment user bandwidth by 20%.
Just Follow the process :-
Click Start–>Run–>type “gpedit.msc”.
This opens the group policy editor.
Then go to: Local Computer Policy–>Computer Configuration–>Administrative Templates–>Network–>QOS Packet Scheduler–>Limit Reservable Bandwidth
Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the ‘Explain’ tab .
Then Enable it and set Bandwidth to 0% click ok.
Top

3. Increase the speed of your menus
This will decrease the delay in opening the menu, when u pause with your mouse on a menu.
a) Open the registry editor by start/run/regedit.
b) Locate HKEY_CURRENT_USER\Control Panel\Desktop.
c) In the right pane find the value name MenuShowDelay.
d) The default value for MenuShowDelay is 400, set it to any value less than 400 or 0.
For this tweak to take effect you may need to Logoff or Restart windows.
Top

4. Creating a desktop shortcut for locking your computer
If you use your computer in an area where others may have access to it, and there are things on your system you would rather have kept confidential, locking your desktop when you leave the computer is an essential task. Here's a recipe for a desktop shortcut that will lock your computer in two easy clicks:
Right click on an empty area of the desktop and choose 'new' then 'shortcut.' The create shortcut wizard will open; in the first text box, type '%windir%\System32\rundll32.exe user32.dll,LockWorkStation' and then give your shortcut an appropriate name on the next page, and hit 'finish.'
You will notice that the shortcut you created has a blank icon. To select a more appropriate one, right click on the shortcut and hit 'properties.' In the 'shortcut' tab, click the 'change icon' button.
In the 'look for icons in this file' box, type '%SystemRoot%\system32\SHELL32.dll' then click 'ok' to see a range of icons for your new shortcut. Choose an appropriate icon. Your desktop locking shortcut is now ready for use. Test it out.
