diskinfo

[singis]

Hello all,
I wanted to know if diskinfo gives the exact size of the disk.
when I do
diskinfo /dev/rdsk/c0t6d0 it returns:
SCSI describe of /dev/rdsk/c0t6d0:
vendor: SEAGATE
product id: ST318436LC
type: direct access
size: 17783240 Kbytes
bytes per sector: 512
So now does it mean that it is 16GB disk. I just wanted to know if that is the exact size of the disk or not.
Thanks,
Singis

17783240 is the numerical representation of the disk capacity. In marketing terms, HP calls this type of disk drive 17 GB disk, if that is what you are wondering about.

[Hakan Aribas]

yes, it is exact size of the disk instead of the size in point of disk vendors (they use 1000 instead of 1024 byte).

Hi ,

See the below Link to see the exact spec nad details of your disk.

Search for the model numbet in seagate web site for details .

This size is shown in KB , if you multiply this by 1024 you can conclude that this disk is a 18GB Disk.

Thanks,

That is correct - it give the size of the disk.

17783240 Kbytes = 16.96 GB

From the model # (ST318436LC), you could say it's a 18GB drive. The size you are seeing - 17783240 - is what's identified by the OS and LVM.

[Geoff Wild]

I think that it is the "usable" space for the OS.

IE:

# diskinfo /dev/rdsk/c0t6d0
SCSI describe of /dev/rdsk/c0t6d0:
vendor: HP 36.4G
product id: MAS3367NC
type: direct access
size: 35566480 Kbytes
bytes per sector: 512


Says it is a 36.4 GB drive - but 35566480 Kbytes = 33.92 GB

Hi Singis,

Though ST318436LC is 18GB disk. The actual will be less ,


Just run this command and it will tell you the actual size of the disk in GB:


# echo "The disk Capacity in GB is \c" ;echo " 2 k \n `diskinfo /dev/rdsk/c0t6d0 | grep size | awk '{ print $2}'` 1048576 / p" | dc



Enjoy ,
Have fun,
Cheers,
Raj.

Hi,

It is a 16.9 GB disk. Just do this arithmetic,
17783240/1048576 = 16.9 GB disk.
