Formatting an empeg's Hard Disk Manually
The sequel to Partitioning an empeg’s Hard Disk Manually.
So, if you’ve followed the instructions on the previous page, you’ve now got a freshly-partitioned empeg hard disk. It’s time to format it.
Formatting the music partition
The music partition is stored on
/dev/hdc4. You should format it with the following command:
empeg:/empeg/bin# mke2fs -m 0 -s 1 -i 131072 /dev/hdc4
This sets aside no reserved space for the superuser (that’s a zero after the -m) and uses 128KB per inode. We use the default block size and tell it to use sparse superblocks, which will speed up
Aside: the builder formats it with
-m 0 -b 1024 -i 131072. This is outdated. Do it the other way.
You should see output that looks a little like this:
mke2fs 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09 ext2fs_check_if_mount: No such file or directory while determining whether /dev/ hdc4 is mounted. Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 92160 inodes, 2926602 blocks 0 blocks (0.00%) reserved for the super user First data block=0 90 block groups 32768 blocks per group, 32768 fragments per group 1024 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208 Writing inode tables: done Writing superblocks and filesystem accounting information: done
Initialising the swap partition
empeg:/empeg/bin# mkswap /dev/hdc6
Initialising the dynamic data partition
empeg:/empeg/bin# dd if=/dev/zero of=/dev/hdc3 dd: /dev/hdc3: No space left on device 33265+0 records in 33264+0 records out
This writes as many zeros as possible to the dynamic data partition by reading them from /dev/zero (which is an infinite-sized source of zero bytes). It’ll stop when it hits the end of the dynamic data partition.
Creating directories on the music partition
The empeg player software stores its database files in /empeg/var, which is usually a symlink to /drive0/var. If this directory doesn’t exist, emplode will fail with a file not found error (0xC0041002). Both disks also need a
fids directory, otherwise emplode won’t see the extra space.
/empeg/fids0 is a symlink to
/empeg/fids1 is a symlink to
So, once you’ve formatted the partition, mount it somewhere (if you’re using the empeg,
/drive1 is a good place):
# mount -n /dev/hdc4 /drive1
Then you can create the directories:
# mkdir /drive1/fids # mkdir /drive1/var
Note that these instructions assume that you’re using your empeg to format a second disk (so you’ve installed it as the slave). If you’ve installed the disk as master, you’ll need to change the above instructions so that “drive1” is “drive0”.
Installing a player image
The steps so far have prepared the disk only for holding music. If you’re planning on using the disk as the primary disk in your empeg, you’ll need to install a player image once you’ve fitted it.
