Using dd to find out cdroms checksums.
Hi:
I issue the command 'dd if=/dev/hdc|head -c 4294607004|m5sum'. But the checksum I get is not the correct one. Its not the checksum of the first 4294607004 bytes in /dev/hdc. And the message dd outputs is
8387904 records in
8387904 records out
Then I find 8387904 * 512 (512 because 4294607004 / 8387904 = 512.0000186) = 4294606848, which falls short of 4294607004 by a few bytes. But 8387905 * 512 > 4294607004. So I issue 'dd if=/dev/hdc ibs=512 count=8387905|head -c 4294607004|md5sum'. However, the message is still the same:
8387904 records in
8387904 records out
How can this be?
Enrique.
