> When you use the dd command to copy the source disk, does the destination > disk need to be the same size/geometry or just as large or larger. if you had two identical harddrives and did a dd from one to another in theory they'd be identical, the alternative is to dd it to a file (so you'd need a larger hd) you could then dd it to a drive identical to the first. if you dd it to a larger drive it'll probably work if they aren't to far off each other size wise/etc. > If it is larger, how do the MD5 checksums end up being the same?

If you simply md5 to the end of the data then it'd be the same. > Dave Goldsmith Kurt Seifried, seifriedat_private PGP Key ID: 0xAD56E574 Fingerprint: A15B BEE5 B391 B9AD B0EF AEB0 AD63 0B4E AD56 E574 http://www.securityportal.com/ ----------------------------------------------------------------- This list is provided by the SecurityFocus ARIS analyzer service.
