That's why I asked. > The number of bytes in the .iso file should be an even multiple of 2048, as that seems to be the standard block size. Certainly the shrike images have sizes that are even multiples of 2048. (It looks to me that other possible block sizes are 512 and 1024, by the way.) Make sure the FTP client (and FTP server) was reading out the exact number of bytes, not KB or MB or something else. If the number wasn't an even multiple of 512, for example, then the FTP mirror has an invalid copy of the ISO file. --Jeremy -- /=====================================================================\ | Jeremy Portzer jeremyp@xxxxxxxxx trilug.org/~jeremy | | GPG Fingerprint: 712D 77C7 AB2D 2130 989F E135 6F9F F7BC CC1A 7B92 | \=====================================================================/
