If the data has been removed out of the recycle bin, then the file becomes unreadable by the application. If no data has been overwritten, certain recovery softwares can recover the file by following the log information and reversing the process. If the data has been over written, it might be lost for ever to the extent that the data is actually ovr written at the bute level. Often parts of the data still remain locked in some slack space within the disk but is not readable thorugh the normal applications. If you use appropriate software which can read the data at byte level, it is possible to recover the data to some extent. This is the science of Cyber Forensics. Naavi
What else can I help you with?
Why are you unable to alter data that is on your CD-R?
Because CD-Rs are permanent. Once written to, the data cannot be erased or overwritten.
Why are CD-R's better than CD-RW?
It can be erased and used again, instead of buying new CD-R's just erase a CD-RW and put the new data on it.
What is a rewritable CD?
Once CD's have data put on them, it cannot be erased. On rewritable CD's, the reflective layer on the bottom of the disc is a different compound that, when hit by the CD drive's laser at increased power, will melt, erasing data so something else can be written in its place.
A CD-R disc can be erased and rewritten only one time?
A CD-R cannot be erased, once media is put on it, it cannot be taken off, but a CD-RW can be erased and resotred as many times as you want.
Can a CD-RW be written and erased?
yes it can be written but unfortunatly it cannot be erased
What are the advantages of a CD-RW?
It can be written and erased thoroughly.
If you want to copy data from one computer to another do you use a CD-R or CD-RW?
Either one is perfectly acceptable. The only difference is that a CD-RW can be erased and used again, whereas a CD-R can only be written to once. Thus if you need to transfer more than 700 MB of data, you will end up using more CD-Rs than CD-RWs.
How can you tell if a CD-R has been formatted?
CD-R can't be formatted. (erased)
What happens in a data while overwriting it?
The data would get erased.
Which storage device doesnt allow the data on it to be erased or rewritten?
What is the name of the storagr device that does not allow the data on it to be erased or re written
How do you erase discs?
CD-r's are permanent CDs and cannot be erased.
Read only CD?
Read-Only CDs (also known as CD-ROMs) are compact disks that have data printed into them in a factory and cannot be erased or rewritten with a computer's CD drive. These usually contain a driver for new computer hardware, or are used to install new software in a computer.
