I have my 640GB USB drive connected to a CentOS 5 server and using fdisk, it seems to show a partition of the correct size, /dev/sdd1, but after mounting, the drive shows only 244M size. Does the message received when running fdisk below mean I should reformat this drive, I can't seemed to figure out how to do that with fdisk. Can someone tell me how to reformat, if needed? The drive is empty, I formatted a while back on a Debian machine.... [root at vhost1 ~]# /sbin/fdisk /dev/sdd The number of cylinders for this disk is set to 77825. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sdd: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdd1 1 77825 625129281 83 Linux Command (m for help): q [root at vhost1 ~]# mount -t ext3 /dev/sdd1 /home/usb [root at vhost1 ~]# df -h|grep usb /dev/sdd1 244M 6.1M 225M 3% /home/usb [root at vhost1 ~]# ls -lah /home/usb total 21K drwxr-xr-x 3 root root 1.0K May 10 14:38 . drwxr-xr-x 8 root root 4.0K May 9 23:26 .. drwx------ 2 root root 12K May 10 14:38 lost+found [root at vhost1 ~]# du -d 1 -h /home/usb du: invalid option -- d Try `du --help' for more information.
