my pc folder in vista

[punjabibadboy]

hi guys
the folder "my pc" does not view the diskspace icon/logo under each disk(C,D,K etc) anymore,
and i don't know how to able this again
it is a disk space bar like the one in this image, that space bar used to be under each disk and that way i could easily see how much disk space i have in each disk

so this bar (i have put a arrow on it) used to be under each disk icon


does anyone know how to able this function again?
thank you for ur time
