I am in the process of cloning a HD. Before I wipe the original drive I was wondering if there was a tool to create something like a md5 hash of the entire drive to verify that I have an exact copy. It does not necessarily have to be an md5 hash and any command line BASH options would work for me as well.
View 1 Repliesi wrote the following script for copy one source harddisk to 5 destination harddisk simultaneously.
dcfldd if=/dev/sda5 hash=md5 hashwindow=1000M md5log=md5.txt hashconv=after bs=512 conv=noerror,sync of=/dev/sdb of=/dev/sdc of=/dev/sdd of=/dev/sde of=/dev/sdf
after finising to run this command the image was trasfered to all harddirve. But no verfication message. i saw the hash value entry in md5 log. how to check the source and destination clone properly
I'm trying to clone a 2GB USB memory stick to another stick just like it (same size and brand). The src drive has three partitions, one fat, one ext2 and one encrypted (in that order). It also has an mbr. I create the clone using the following command:
dd if=/dev/xxx of=/dev/xxx bs=512k conv=noerror,notrunc
Once it's done the mbr, the ext2 and the encrypted partitions seem fine, but the fat one is slightly modified on the clone. Here is a hex dump of the (broken) clones fat partition followed by a dump of the original partition.

Best way to do a scheduled backup of a server (PowerPC, Ubuntu 9.10), when an exact copy of the linux partition would be made on a disk of the same size? It seems there are several solution, but I have problems choosing the best.
View 6 Replies View RelatedI back up all my digital photos to a couple of places. I've been using the cp command, but--given the personal value--have started to wonder if there's a more reliable way. I'm no stranger to Linux, Bash, Perl, etc., so I could write something to copy and compare md5 hashes, but I was wondering if something already exists (reinvention, wheels and what-not).
Most of my googling for copy and (verify|valid|check|hash|confirm) turns up rsync. However, as far as I can tell, rsync only uses hashes to see if a file needs to be updated. It doesn't perform a hash comparison afterward. For this use, specifically, the files are binary and typically 8-10MB.
Id like to know if its possible to somehow copy an EXACT copy of my linux from one computer to "paste" on another!
And how would I be able to do this?
I want to backup my server that godaddy is hosting and install it on my linux system at home. In other words I want to have a clone of my server at home, like what timemachine does on mac (carries files and programs from one mac to another to make a clone).
How do I do that? I create an image file an iso file? or what? How?
I want to do this incase my server burns up over there. I don't want to reinstall all the programs and do the set ups manually again.
Create a copy of the file above and call it commands.sorted. Use the vi command to manually sort this file. I.e. use yy to copy a line, P or p to paste a line, and dd delete a line. Order the commands with the two lines starting with double quotes first. Then list the rest of the command in alphabetical order.
Anyone have any ideas what he's talking about? Can I copy a file and rename it at the same time while copying it to the same exact directory again? Now sure what the two lines things means either. I have an email out to him but it usually takes a long time for him to answer me. I got alot of work to do so everytime I get hung up it kills me.
I want to copy all files with the name XYZ* into one folder. The problem is that the files are in different subfolders and that not even the depth of the folder structure is the same for all files. Luckily, at least each file has a unique name.
Of course, I thought about the cp command but I guess the depth of the folder structure needs to be the same for this to work.
I'm trying to make an exact duplicate of just a folder (about 15 gigs) and I want to do it a "slow method" (basically I want to avoid any possibility of corrupting files. Is there something more useful than cp, I've been using that and I've noticed at least a few files have gotten corrupted.

View 3 Replies View RelatedIs there any utility that can provide a list of all files, and both the file size and md5 hash value.

When I set up the spreadsheet for printing - and "print preview" the document, I see hash marks in place of numbers in a majority of the cells. When I print the document, the hash marks are printed, in place of the numbers. When I view the document under normal circumstances, for editing - the hash marks are not present. All seems well. I cannot print the spreadsheet without the hash marks (#####) appearing!

I originally installed 11.04 on this system with the same disk so I'm confused as to what is happening. I have tried using different CD's and even installed of a USB. The memory test of the installer came back okay. The box has two PCI NICs that are recognized and functioning. The only package I have installed is openssh as this is a headless box. What makes this even more odd is that I have a newly installed 32-bit 11.04 server with the same procedure on the same network and it does just fine.
I hope I have been thorough enough in my search and investigation that someone can point me in the right direction. After reinstalling 3 times I am at a loss and I know 11.04 can run on my box without problem (as it did before the reinstall).Tonight I'm going to reinstall with the built in interface unplugged and the two NICs removed, I'm hoping this will prevent apt from bricking itself during the install, which is the only think left I can think of. I suspect the issue has to do with the nic despite it appearing to function properly I am unable to uncompress the archives in question on, my workstation, when they are downloaded on the sever but can successfully uncompress the same files when downloaded on the workstation.
SOLUTION: I pulled both NIC's and enabled the integrated interface and it is all working. I wonder why they didn't work though...

I wrote a very simple script to compile a Tex document and open the resulting PDF output file. The problem I have is that every now and then there are multiple PDF files in the same directory. For example if I have a file called test.tex I run my script and it compiles the test.tex and creates a file called test.pdf If there are only one tex and pdf file in this folder there is no problem. If there is also a 1.pdf in this folder the test.tex will compile and 1.pdf will open.
My question is: is there a way to open the exact pdf file that was created by the .tex file?
My script file is this:
#!/bin/sh
pdflatex *.tex
gnome-open *.pdf

I have been trying to install scourge, and whether I go through the playdeb route, or compile by source route, in both cases the file is corrupt. With playdeb, the data folder has a hash sum mismatch. When I try and compile by source, the tarball can't extract (I'm thinking for the same reason).
If my ISP is causing this, how would I stop it, short of connecting to another network?

I have an OCZ Vertex SSD...the 30GB variety. recently I upgraded my kernel to 2.6.33. I have read that that is all that is needed in order for trim to just start working. Is there a way that I can verify that TRIM is working?I'm debating getting the Vertex2 100GB model because I love my SSD now, but would love to have a little more storage space. I just don't want to buy it without TRIM working.
