I've got a problem when using _taccess() function:

int nAccess = _taccess("x:", 06);

x is my DVD-ROM. This function returns different result in WinXP and Win7: in WinXP, the function returns -1, which indicates it is NOT writable. But in Win7, the function returns 0, which indicates it is writable.

How does it happen? So what can I do if I want to check DVD-ROM (such as "x:") writable?

Just to be clear, is the disc in the drive writable (burnable)? – Anders Mar 21 '12 at 02:56
A DVD-ROM is never writeable. Why would you need to check that? Are you talking about a *drive* or a *disc*? – Cody Gray - on strike Mar 21 '12 at 04:29
Sorry, my description is not clear. I want to check the writability of a disc, such as DVD-R or DVD-RAM disc. – Sean Yue Mar 21 '12 at 05:50
