Hi,
I am facing with this weird problem. df is reporting incorrect disk space usage! Running du instead, reports correct space usage. I have listed the outputs of both the commands.
I have 40 GB HDD with 4 ~10GB partitions. I have setup the linux part on the last 10 GB, with 4 partitions namely /boot, /swp, /home and /root.
The incorrect sizes are w.r.t the fat32 partitions. Disk space usage for the ext3 partitions are correct.
My partition table is as follows, [EMAIL PROTECTED] anand]# fdisk -l Disk /dev/ide/host0/bus1/target0/lun0/disc: 40.0 GB, 40060919808 bytes 255 heads, 63 sectors/track, 4870 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

(Note: Formatted o/p, dev is -> dev/ide/host0/bus1/target0/lun0/part1)

Now, [EMAIL PROTECTED] anand]# du /mnt/win_c ... 7.6G /mnt/win_c (Which is correct, but df reports only 3MB free!)
[EMAIL PROTECTED] anand]# du /mnt/win_d
...
8.8G /mnt/win_d (Again wrong!)
(This is new. Earlier I use to always get 100% free for df. I recently deleted some installables over 700 MB is size and this information has changed since then)
[EMAIL PROTECTED] anand]# du /mnt/win_e ... 9.3G /mnt/win_e (This is correct)

Any pointers to where I should be looking at will be really helpful.
Thanks, -Anand
