I read many web pages on how to use the dd command, but all have different block sizes and I am confuse. I see some as bs=512 bs=1024 bs=8192, etc.... Is there a way to calculate the block size of the two hard drives myself or is there a standard block size to use for any hard drive, cdrom and floppy. I appreciate your help Thanks David V
