This is the first time I have made my own install disks, instead of buying a boxed set. Edmunds Enterprises apparently doesn't sell them anymore. The checksum values are listed on the download site, but how do I compare them with my downloads? My ext3 partition is formatted (blank) awaiting installation, so I will have to do this in Windows, and I don't know how.

How can I checksum a directory?
Using both cksum and md5sum yields the same error
Code:
root@linux# cksum /bin
cksum: /bin: Is a directory
root@linux# md5sum /bin
md5sum: /bin: Is a directory

send me the code to find the md5 checksum of a file in c++.

Once more I am playing with Linux. First it was Mandrake on an 386/33 box. Then Ubuntu 8.04 on an Athlon 64 box. And now Ubuntu 10.04 on an Athlon 64 Black. In Windows, there are beaucoup utilities, such as disk cleanup, dupe file finder, et cetera. I already know to NOT defrag a Linux HDD. Is there a need for any of the more common Windows disk utilities in Linux? FWIW - If I don't run Norton Utilities, CCleaner, and Glary Utilities regularly in Win7, I endup with gigabytes (yes, gigabytes) of trash files.

View 3 Replies View RelatedUsing Ubuntu 10.04 on an old HP DV4000 laptop. Trying to do a backup from my laptop's disk to an external USB drive using DD while booted from an Ubuntu boot disk. The laptop's hard drive is not mounted. I was also using a checksum to verify the backup against the hard drive like so:
Code:
$ dd if=/dev/sda of=/media/usbdrive/whatever.img
$ md5sum /dev/sda > laptop.md5
$ md5sum /media/usbdrive/whatever.img > img.md5
Unfortunately over two separate attempts I have not got the checksums to match. However, I have mounted the dd image and retrieved part of the backup from the image, with no apparent corruption. Are there any reasons other than data corruption that could be causing this? I have not tried to restore from said image to see if it "works" (for obvious reasons).
I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.

I have a large tarball which is bz2 compressed, and I would like to get a md5 sum of the files contained in it, as I have a separate directory on another server containing what I think are the same files. I want to check to see if the tarballs files are the same as the uncompressed files on the remote server. The files are big 10gb+ so I was wondering if there was a quick way without having to uncompress them all and then md5 them.

OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?

I have downloaded both fedora 11 64bit DVD iso and fedora 12 64 bit live cd,but the install failed on a brand new AMD Athlon II X4. The f11 was polite and said there were errors in the media, but f12 displayed an illegible line of text and stopped. On prior installs there was a obvious checksum value to verify that the download was good So far I have been unable to find one. I'd like to verify that the download is good before I buy more crappy cd's that don't work.

I am attempting to do a new install of OpenSUSE 11.2 x86-64 by burning a network install disk. I am having trouble getting it to work on my hardware however. Whenever I boot up with the disc, I get a "image checksum error." I have tried to redownload the image and also reburn it. The disc will boot in VirtualBox but will not boot on the machine. I do not understand what could be causing this because the CD drive in the machine is working just fine.
