Hi All,
Wondering if ne1 can plz tell me, what is the sector size in bytes on a DVD and how many sectors are there on a 4.7GB disc.
Thanks.

Sector size = 2048.
Sectors varies from disc to disc slightly, here is what my current batch comes up as: 2,297,888

@ Lightning UK,
Thankx a bunch for the prompt reply. What I understand from your post is that a 4.7GB disc has 2,297,888 sectors and each sector is 2048 bytes, right ?
You mentioned that sectors vary from disc to disc, how do I calculate it ? What would tell me if there is a difference ?

Regards.

They should not vary :(

You can easily find out the number of sectors with cdrecord-prodvd and with dvddecryptor
