I've got a small disk whose contents I'd like to save as an image file, in case I ever want to write it back to the disk it came from. This is a 4MB flash disk. From what I gather in my Linux reading, I should do something like the following: hook this tiny IDE disk up as, say /dev/hdb and the do something like "dd if=/dev/hdb of=dev-hdb-image.img" ? ? ? (the question marks outside the quotes indicates things I'm not sure about). This will write an image file to, I suppose the current dir - correct? Is the output file's name somewhat a matter of indifference, as it seems to me? E.g., wouldn't necessarily require any extension (might be called simply "dev-hdb-image"), though an extension might help me keep track of just what sort of file it is. And, finally, the question marks: I see sometimes "bs=512" or some such following the proposed file name which, as I get it, refers to block size. I'm not really clear on block sizes and what they do, but I have run accross information indicating that, in the case of an image file, it's not too important and can be left out. Can anyone illumine my benightedness on this matter?
Thanks, James PS Ray, I recall you asking at some point not long ago about copying one disk to a disk of a different size. In Rute User's Guide he writes "If they (disks) are not the same size, you will have to use tar or mirrordir to replicate the file system exactly." I guess you got that task accomplished, but did you do it using this means, or by some other? - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
