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.

")when using VWIN32_DIOC_DOS_INT25 for read. Can you guess this error.
