Comfortable dd bs= parameters for different media
Hi, I'd like to ask which sizes are comfortable to use for reading from different media using the dd utility. As far as I know, these are good values: Format Device (example)bs= - - Data CD /dev/acd0 2048 Music CD/dev/acd0t012352 DVD /dev/acd0 2048 (?) Hard disk /dev/ad0s1g 1m (?) The usual command is % dd if=/dev/see-above of=somefile.dd bs=whatever What about copying partition-wise from a hard disk to a dd file? Which bs= parameter would be encouraged to use? -- Polytropon From Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

What about copying partition-wise from a hard disk to a dd file? Which bs= parameter would be encouraged to use? Presumably the destination file will also be on hard disk (or USB flash, or SSD). It may be ok to use 1m then :) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I'd like to ask which sizes are comfortable to use for reading from different media using the dd utility ... In case anyone still cares, I have long used bs=120b for floppy disks. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
