That would make the live FS painfully slow, and it wouldn't make a big difference from the default (16K). It is already noticeably slow with the default cluster size of 16K on my test machine (a 1 GHz VIA C3), so would rather prefer to use 2K cluster size, even though compression will be not quite as good. (2K is the minimum, less than that doesn't make sense for CD9660 media because the physical sector size is 2K.) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co.
