Question about windows disks and partitions
Dimitris Diamantis (ftso)
I use the command "psutil.disk_partitions(all=False)" on windows xp
(guest on a linux virtualbox host) and return the device "C:" with
mountpoint "C:",
the device "D:" with mountpoint "D:"
and the
device "F:" with mountpoint "F:".
C and D are partitions on the same disk and F a partition of a usb
flash drive.
Then i run the command "psutil.disk_io_counters(perdisk=True)"
and return the output below:
{'PhysicalDrive1': iostat(read_count=6, write_count=26,
read_bytes=49152L, write
_time=5210L, write_time=956L), 'PhysicalDrive0':
iostat(read_count=2970, write_c
s=64539136L, write_bytes=245547008L, read_time=4647317L,
write_time=2028993L)}
The i remove the usb flash drive and i run again the command
"psutil.disk_io_counters(perdisk=True)"
The output was same as above.
Why the flash drive not shown on the output of the first run?
Is there any way to map the PhysicalDrive[x] of the disk_io_counters
output with the letters (C,D, F, etc) of disk_partitions output?
Thanks!

I noticed a mistake.
C and D are partitions of several disks and not the same.
Sorry.

I ran the WinObj and i took a screenshot...

I can't understand where is the problem :S
On linux the command "psutil.disk_io_counters(perdisk=True)" returns
info per partition and on the windows info per disk?
I think that the best output for windows should be like this:
{'C:': iostat(blablabla), 'D':iostat(blablabla), etc...}
