Who has not happened to burn a data CD or DVD that when inserted into the computer it notifies you that it is empty or blank? Or that when you burn multiple sessions (in multi-session), our team shows only the data recorded in the last session, losing access to old files? "
Loss occurs in many cases like this, where we get hands on the head because we lost all these documents with information about the world domination planned to take place next weekend.
The problem, in most cases, is due to three reasons:
1. Conflicts with multi-session:
All (almost all) know that a CD or DVD can be recorded once and can not delete or modify data once stored. Unlike CD-RW or DVD-RW (rewritable) discs that can record and erased many times.
cd layers
Well, the first statement is not entirely accurate. It is correct that data once stored can not be deleted / modified, but it is possible to store data in small "clusters" leaving open for a future CD recording on "groups". So, we can burn to a CD a group of files occupying 200MB, there still remained the remaining spare capacity (up to 700MB) for a subsequent recording. This is called multi-session recording, and the groups are called sessions.
Occurs, then, that many people (either through ignorance or carelessness) to want to continue recording, instead of "Continue the session" choose "Start a meeting", so the software understands that we want to start recording a new session from scratch rather than continue the previous.
2. Inconsistencies with the ISO format:
iso nero
In some cases, put the example of Nero software, which is the most widely used recording package-ISO mode causes problems. When recording a CD we can choose between two modes: Mode 1 and Mode Mode2/XA-CDs.
2/XA Mode is the current format. However, the CDs recorded with the ISO format can not be read from older CD readers. However, Mode 1 is compatible with all readers, ideal if you have any old CD player, car, etc. To learn the characteristics of recording a CD ISO in both modes have the following table:
CD 74 min. CD 80 min. CD 90 min. CD 99 min.
MODE 1 650 MB 703 MB 791 MB 870 MB
MODE 2 738 MB 798 MB 897 MB 987 MB
We must also bear in mind that if you create a multisession CD with several sessions in Mode 1 and Mode several other 2/XA our CD you may have problems being read on many CD players (not necessarily old).
ASPI driver problems:
ASPI drivers are a universal drivers are responsible for the proper functioning of recording applications. Normally, when you install a software update record and thus we can have problems such as' we recorded the CD and our team will read correctly, but the format (and still have burning software installed (and therefore The ASPI)) tells us that the CD is empty or contains no data.
Finally, how I can recover my data CD or DVD?
CD Recovery Software
A program called Stellar Phoenix, which is capable of recovering any type of CD or DVD, sessions "invisible" to windows (as I mentioned above), images, etc ...
Highly recommended if you want to retrieve data from a CD or DVD with any of the above problems.
