Is Your CD Feeling Itchy?

How to Burn and Maintain Your CD/DVD/BD/HD DVD

Burn it!

USB drives have replaced the way we deal with data portability. We all know that CD’s are delicate and prone to scratches. The only way to keep the CD’s in working condition for maximum amount of time is to handle them with “paranoia care”, something what i call. It’s almost like the CD’s are always itchy and will get scratched by somebody, someday or the other. Even though it’s zillion times rational to preserve data on CD’s rather than on the pathetic 1.4 floppy drives. Yes, even in the age of thumb sized terabyte capacity USB drivers, I’ve seen people still dealing with floppy drives with storage capacity of only 1.38 MB.

CD’s are used for many reasons and all of them serve a different purpose. But, when the CD’s are scratched, the chances of data loss increases and things can become difficult if the scratched CD’s are full of important data. In many cases the CD’s are non-readable because either the surface is damaged, stained or just full of finger impressions. The following are some basic tips that can and should be followed to ensure maximum data life,

CD Burning speed: Using good quality CD’s fir burning is essential for better data protection and storage life. One of the common mistakes made while burning CD’s is that the data is set to burn highest speed. If  the CD’s are burnt at a very high speed, say 48x which increases the chances of bad data on the burnt disk. It is advisable to burn the CD’s at a least possible speed say 4x or 8x to ensure  the data is burnt accurately. Why is it so? The answer can be found at Link 1 and Link 2.

Also, it is better to not multitask on a computer with average hardware configuration while burning CD’s. This because the CD burning process consumes a lot of RAM and is busy communicating with the data to be burnt and other concerned areas. If the user is performing some other task along with the burning process, it’s stresses the computer and may interrupt the burning process.

CD storage: It is advisable to store the CD’s in proper CD cases and in an area with a room temperature not less than 20°C (68°F) Greater than 4°C (39°F) to avoid any damages occurring due to incompatible temperatures. As recommended by: Archival Storage Facility—Recommendation for storing CD’s and DVD’s together.

Using Cologne for cleaning: If the CD surface is greased or stuffed with finger impressions, clean it with a soft cotton cloth with few drops of cologne. Make sure you apply the cologne on the cloth and wipe the disc “from the center to the outer surface” in single down motion. Rubbing the CD surface back and forth will successfully invite scratches.

Data Recovery Method: If your CD has reached a stage where you encounter “Cyclic redundancy error” a.k.a damaged enough to avoid you from accessing the data, it’s time to use a Data recovery application. ISO buster (Windows and Linux) is very good at recovering data from damaged disks CD/DVD/BD/HD DVD. There have been cases where i had successfully recovered all data from a bad CD. And sometimes, i could recover a part of the data. It all depends on to what extent the surface has been damaged. But, it’s better than just dumping the CD away with total data loss. Isn’t it?

The on going fight against piracy

It’s a Piracy Vs Anti-Piracy War

Few years ago Microsoft silently released a Tool via ‘Automatic Updates’ to check and notify the Windows user about the genuineness of the Operating System, an attempt to fight against piracy. It indeed created a chaos for Windows Users and as a result, numerous patches were available to get rid of the nagging notification within no time. The surprising thing is that the Windows Genuine Advantage (WGA) Validation Tool is so poorly constructed or should I call it “lame” that any user can block and remove it with the help of tiny patching applications and even by manual efforts. I don’t know how many Windows users Microsoft has been able to scare enough and make them actually buy a original copy of Windows OS, it is indeed interesting to know the number.

I live in India and few weeks ago I was standing in a queue to renew my railway pass. We have a TV screen installed on the top of the railway ticket counter. It wasn’t for entertainment purposes but was actually an ad slot. What caught my attention was unusual and shocking! The commercials were setup to play from a computer using Windows XP and which was pirated too! During one of the commercials, a WGA window popped in and stated that ‘the installed copy of Windows is illegal and the user should buy an legitimate one.’ (These are not the actual words but something that I perceived). This proved to me that Microsoft or any other company in its pursuit to fight against piracy is way too far from killing the root of it.

Piracy has become like a uncontrollable pandemic disease. Remember the shutting down of Napster? Lars Ulrich, a drummer from a heavy metal band – Metallica, filed a suit and brought down Napster, because one of their studio recordings they were working on was already available for free download on Napster P2P. But, what was the result? Thousands of fans protested against Metallica for their action and majority of them were users of Napster P2P. But, this did not scare the pirates at all and numerous other P2P sharing portals were established, soon after Napster was successfully shut down. Even the renowned P2P sharing portals like Demonoid and PirateBay have also “suffered and survived” form major law suits and recently, thirteen Hollywood production companies have filed a new lawsuit to try to get PirateBay.org shut down.

Practically, there is no end to the war and the best way to put an end to it is by doing what smart enemies would do. Teaming up and re-framing the strategies that they have been following. (Reminds me of the recent Microsoft-Yahoo deal) This is the smartest way to make things more productive for everyone. But, who knows what is brewing in the minds of the “big guys” ?

Gmail Notifier HTTPs Patch

July 22, 2009 by Raj Agrawal 2 Comments

Using Gmail Notifier With HTTPs Authentication

Google is well known for it’s “privacy policies” and also for it’s honest “Sophistication, with simplicity”. Gmail Notifier, a Google product, is a tiny freeware application which provides an instant notification regarding new email.

Almost all the Gmail users are aware that Google has introduced an option to access Gmail with more security i.e users can login to their mailbox with https://gmail.com rather than with the regular http://gmail.com. Now, Gmail Notifier users have noticed that after setting the Gmail access through https, they were no longer able to get new notification through Gmail Notifier. The obvious reason is that Gmail Notifier, by default, is designed to access the mailbox through basic http authentication and as a result Gmail Notifier fails to provide you new email notifications.
To make the Gmail Notifier work with the new HTTPS setting, you’ll need to install a small registry patch available on the following link:
