Hi all,

dd: ‘/dev/sr0’: cannot skip: Invalid argument
0+0 records in

0 bytes (0 B) copied, 0.000301689 s, 0.0 kB/s
but
{3464-jd@localhost}$ time dd if=/dev/sr0 of=Our_Group_Picnic.iso bs=64M
conv=noerror,notrunc
works just fine.
So why is it that skip des not work on optical media?
Skip works fine, but you must specify the units. "skip=5888" doesn't
tell dd how far to skip. E.g. "skip=5888c" would skip 5888 bytes. From
the man page:
N and BYTES may be followed by the following multiplicative
suffixes: c=1, w=2, b=512, kB =1000, K=1024, MB=1000*1000,
M=1024*1024, xM=M GB=1000*1000*1000, G=1024*1024*1024, and
so on for T, P, E, Z, Y.
