[SOLVED] How does one determine a USB hard drive capacity in sectors?

Hi All,

How would one determine the capacity in sectors or LBAs of a USB Hard Drive? If I know the USB device number, like from 'lsusb', is there someplace on the system to get other information about the drive? What I want to do is have a program go out and get this information just for the number of LBAs on the drive itself. Partition info doesn't matter for what I am doing.

Thanks,
Elena Quinn

I believe /sys/block/sdX/size may be in sectors .. multiplying by sector size seems to give the correct disk space

cheers

hi equinn,

if you have linux, plug in the USB, and then from the terminal run the command "fdisk -l". I think this should give you the sectors in the USB.

Regards.
