Questions
I have purchased a new 40x12x48 CD-RW drive and now I need two questions answered. First, when you buy CD-R and CD-RW media, how does the speed affect the quality of the final burn, especially when burning at higher speeds? - Second, should you use the best quality blank CDs?
Answers
Last question first. - The 10x (or any x specification) is not a designation of quality, but just the recommended burning speed. For instance, a 40x CD can be burned at 40x or lower, but a 10x CD may or may not burn at 12x.
I personally have never experienced any difference in quality when burning a CD at high compared to lower burning speeds. However, sometimes you may need to burn at a lower speed in order to avoid a buffer underrun error. You should go ahead and buy CDs that have high recommended maximum burning speeds (as long as they aren't too overpriced), and just burn them at the maximum recommended speed. CD-Rs and CD-RW discs are so cheap nowadays that everyone can afford to experiment. With CD-RW discs you can erase any faulty burns and redo them, but you will have to throw away any aborted record-once CD-R discs.
Problem
I have created a database with MS Access that is 2MB in size. I used Adaptec's Easy CD Creator - Standard Edition to burn the database to both CD-R and CD-RW discs. But whenever I attempt to open the database from either type of disc, the message "The database K.M.S. is read only" appears. I want to know how you can transfer the database to another computer so that data can be added to it and design changes can be effected.
Solution
Easy CD Creator creates a disc that can be used in the same way as a CD-ROM disc is. CD-ROM discs are read-only, so you can't write to CDs created with Easy CD Creator. Even if you copy the files from the CD to the hard drive, they will be set to read-only. You have to right-click on each file, click Properties, and then uncheck the Read-only box.
However, the Universal Disk Format (UDF) allows you to write to CDs in the same way as you can write to floppy disks, but you need to use software that can use this format. Adaptec's Direct CD is a program that provides this facility. Note that the computer to which you want to transport the database has to have CD-writing software installed on it that can handle UDF.
It is not advisable to access a database directly from a recorded CD, because database software writes to many different records in various parts of the file, and, because of the nature of CDs, accessing the information will be very slow as the blocks of data are copied to the hard drive, Windows finds the relevant data within them, and then brings it to the screen. The best method is to copy all of the files to the hard drive, work on it there, and then copy the modified version back to the CD. This method is especially effective when using CD-R discs that can only be written to once.
