Hi,
I'm developing an application for interacting with pen drive in Windows XP. I used createfile() to get handle. Further I need to read/write data from the specified sector.

I used ReadFile()/WriteFile() for read and write, but
here i'm unable to specify a sector number to read/write from a
specified sector.

I also used IOCTL_DISK_READ for reading data from a specified sector, but it is not supported in windows XP(it works only in Windows CE)

Can anyone help me.

Regards
S.Mohanraj

Thanks. I'ad used what is said in the above link, but i get the error code 50(i.e "The request is not supported.
")when using VWIN32_DIOC_DOS_INT25 for read. Can you guess this error.
