Re: About RockRidge
Hi Michelle,
Tks for your further advice.
I re-did it but still encountered problem. I ran Knoppix LiveCD to
make this test
PC
Athlon 1.4G
RAM 512M
Steps performed as follows;
Started Knoppix LiveCD as root (Knoppix 1 --> startx)
sh-3.00# dd if=/dev/zero of=new_cd_image.raw bs=1M count=100
100+0 records in
100+0 records out
104857600 bytes transferred in 0.505724 seconds (207341591 bytes/sec)
sh-3.00# mkfs.ext2 -b 1024 -m 0 new_cd_image.raw
mke2fs 1.38 (30-Jun-2005)
new_cd_image.raw is not a block special device.
Proceed anyway? (y,n) y

This filesystem will be automatically checked every 20 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
