Hi,

To see the size of all disks and partitions (SCSI and IDE):

PHS7:/proc $ cat partitions
major minor #blocks name

   8     0    2202244 sda
   8     1    2200873 sda1

   8 16 4406935 sdb
   8 17 4401778 sdb1
   8 32 4406935 sdc
   8 33 4401778 sdc1

   3     0   14668416 hda
   3     1    1951866 hda1
   3     2          1 hda2
   3     5     128488 hda5
   3     6   12586896 hda6
   3    64    9770544 hdb
   3    65          1 hdb1

3 69 9767457 hdb5

sda = size of the first SCSI disk.
sda1 = size of the first partition on the sda disk. hda = size of the first IDE disk.
hda = size of the first partition on the ide disk.

HIH,
Antonio Belloni

for an IDE drive do:

cat /proc/ide/xxx/capacity

...where xxx is the disk drive u're interested in (hda, hdb,...). The size returned is in 512b blocks

for SCSI it's not that easy
