If I understand it correctly the CRC at the end of the data area of a sector is generated when a sector is written to. Subsequently, the CRC is checked when the sector is read - if the CRC value doesn't match then it's flagged as bad and some type of error should occur. So my question, if I use a disk utility such as diskedit and change the data area (i.e. add a line of text to a document) in a sector. Why then does the sector CRC not report an error when accessing the file normally at a later time? or is this done with an ECC and it's correcting it on the fly as there would be no physical issues with the sector...? thanks ----------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
