Hi,

I wanted to know those methods.

I know one method..

in Linux, by calling IOCTL system call with requrest parameter
BLKSSZGET , I was able to get block size.

For CDROM it is giving 512 and for REV disk it is given 2048.

is there any other method to cross check

Regards

You have to look into the documantation.

Yes please, check the 'documantation'. The 'documantation' never lies.

Now Arnie, what if the 'documantation' says that the sector size can
be any size betweeen X and Y?
 
yes. download and run SCSI Utility for Windows. After scanning for devices,
hightlight the disk you're interested in and send a READ CAPACITY command
using the Menu item entries.

Device-specific.

Some numbers true today: HDD: 512 bytes, CDROM (data!) 2048 bytes.
MOD: 512 bytes or 2048 bytes, depending on the disk, not the drive.
