General :: Scalpel Carver And Skipping Blocks?

Oct 1, 2010

I'm working on a ~1 TB disk that was loaded with all kinds of images and documents that lost it's HFS+ partition table. The person for which I'm doing the favor of running scalpel says it's likely there's 90GB of stuff. Somehow, the disk got relabeled/MBR changed to some FAT variant that works on the whole Terrabyte.

Attempts to recover the partition info failed.My first try with scalpel finds more than 90GB of image file headers alone and that blows through all of my storage. Of the headers found and recovered as images, a simple test shows most of the image files are broken. The cluster size option does not work if I use it by itself. It errors out before it gets going.I want to speed things up and skip the countless broken image files.

Why does the following command tell me that the scalpel.conf file doesn't exist ? I know it is there; I can navigate there through the GUI.

General :: Clonezilla Skipping Partitions In LVM Partition?

May 24, 2011

I'm trying to backup a drive with an LVM2 partition. 8 of the 10 partitions in the LVM restore fine, two do not. SDA1 is the boot partition, SDA2 is an LVM2 partition with 10 partitions inside of it. When I restore the image created by Clonezilla the partition names are there but two of the partitions are unreadable and unmountable. I'm certain Clonezilla is skipping these two partitions because its entire image is around 40G and when I TGZ these two partitions I get an 80GB file. Clonezilla doesn't appear to give any errors and as it "winds up" it shows that it's unmounting the LVM partitions and I see my missing two in its list but when Clonezilla makes the image it never mentions the two I (really) want. I'm trying Clonezilla's DD method right now but it appears to be DDing each partition (going through the LVMs right now).

Ubuntu :: Cannot Delete Files Created By Scalpel

Nov 23, 2010

I ran Scalpel to retrieve some files from an old HDD, what I didn't realise is how much larger the output from Scalpel is than the original disk space.

So what happened is at about 5% of files carved (pass 2/2) my disk space was full and the program aborted.

Then when I rebooted Ubuntu I can't get in unless using Recovery Mode.

I think this is because there is no disk space left. The error I get is to do with Gnome Power Manager not being configured, I never had this error before.

So I went into CLI prompt and performed 'find -maxdepth 2 | grep *.mpg' and I can see a tonne of mpg directores called ./~/mpg-1-6, ./~/mpg-1-7, etc, and they all have lots of files.

Now I have no way of deleting these, I tried using 'sudo rmdir */*mpg' and it cannot find the directory.

When I go to my home folder and 'sudo ls -al' these aren't listed.

The only way I can see them is using the 'find' command.

Can I chain the find command with a delete command somehow?

General :: Can't Find Bad Blocks List

I've got a new hard drive, formatted it to ext3, and made a check for bad blocks using e2fsck.

It gave me this:


I just would like to know where i can find how many bad blocks were found (perhaps one if it is using singular in sentence "Updating bad block inode."?), and what is/are the number(s) of located bad block(s).

General :: Determine Number Of Blocks For A Partition?

Jul 1, 2010

Can someone explain how to determine the number of blocks to determine the number of cylinders for a new partition on hard drive.

Why is block size divided by 1024?

I think I understand unit size is the total bytes per cylinder, I get that. I understand the anatomy of the hard drive (i.e. heads, sectors, cylinders.

My problem is, if I need to calculate the number of cylinders needed for let's say a 20G partition on a 120G drive.

General :: View Bad Blocks On Mounted Ext3 Filesystem?

Mar 18, 2011

I've ran fsck -c on the (unmounted) partition in question a while ago. The process was unattended and results were not stored anywhere (except badblock inode). Now I'd like to get badblock information to know if there are any problems with the harddrive. Unfortunately, partition is used in the production system and can't be unmounted.

I see two ways to get what I want: Run badblocks in read-only mode. This will probably take a lot of time and cause unnecessary bruden on the system. Somehow extract information about badblocks from the filesystem iteself. How can I view known badblocks registered in mounted filesystem?

General :: Filesystem Corruption Possibly Caused By Bad Blocks

Nov 5, 2010

I'm trying to RMA a month old SSD, and they're giving me a hassle about it. The drive currently seems to work just fine, but I'm 95% sure that a few blocks went bad and corrupted some data about a week ago. I was able to mostly recover the data and correct for the bad blocks, but I don't really trust the drive anymore.

I'm running an up to date Debian Squeeze install with ext4 on this drive. My system started doing some bizarre things, to the point that it was unusable, so I rebooted it. As it was booting up, it complained about needing an fsck, which found dozens of non-trivial errors that it was mostly able to fix. It then proceeded to boot normally, except the drive mounted itself as read only (due to errors). Another fsck turned up a similar number of problems. This happened a couple of times before I ran fsck with '-c', which is supposed to scan for and work around bad blocks. That seemed to fix the problem, it hasn't given any more problems since then.

The manufacturer is refusing to RMA the drive unless it's completely unmountable right now this minute, saying that it was a one time problem that could have been caused by anything. Am I right in thinking that the problem has to have been with the drive if 'fsck -c' fixed it, or could something else be going on? If it was the drive, am I somehow being unreasonable in asking for a new one while the current one is "working"?

General :: Implications Of Bad Blocks When Reinstalling A Disk Image

Mar 17, 2010

Let's say I'm using one of those PCs that uses a SSD flash drive in place of a more regular HDD.

Say I burn my favorite .iso distro and install it on this PC. I install my favorite applications and seek out and install any missing drivers and generally tweak the system like you do. When I am finally happy with it, I make an image of this installation to an external USB drive.

Now, say 9 months later some of those SSD blocks have gone bad because they were erased too often. They're no longer usable. Also, because I'm a sloppy person who can't be bothered to delete redundant stuff and run make-cleans and so forth, the disk is getting pretty cluttered and takes longer and longer to do stuff.

I decide the obvious solution is to remove and save any data I need to keep, then just over-write the disk with the image I made 9 months earlier.

The question is: will the firmware be smart enough to re-map my incoming image to avoid these bad blocks on the SSD? Or am I going to wind up with some parts of the image being located on bad areas of the SSD?

General :: Partitioning / Perform Bad Blocks Scan On Root Partition

Nov 28, 2010

My root partition is formatted as ext3 and I would like to perform a bad blocks scan on it. Normally e2fsck -c -c does this, but you can not run it on a mounted partition. I know it is possible to force a fsck to run at boot by creating the file /forcefsck but is it possible to specify that it should also check for bad blocks? If not, what is the recommended way to check for bad blocks on the root partition? I would like to avoid having to create a rescue disk and boot off of it.

I tried GStremer and Xine engines, tried Amarok, Banshee.... always the same - radio streams skipping. I never found a way to increase buffer for Internet streams. Updated to last versions , still the same.

Ubuntu :: .ogg Files Skipping But Not In Windows?

Jan 18, 2011

I have noticed that my music, which is all in .ogg format, is skipping every once in a while in Ubuntu, but not in Windows (I use Banshee in Ubuntu; Winamp for when I use Windows). My whole music collection isn't skipping entirely--that is, not every music file has this problem. However, the ones that do, the music file skips like a scratched CD for 1-2 seconds. The same music file doesn't do this at all when played with Winamp in Windows. Are my music files corrupted? What is going on? None of the music files were like this before (with the skipping), but for some reason, the skipping occurs only in Ubuntu, not Windows/Winamp. Not every music file has this happening, but some of them do.

I have been thinking about converting all my music files to .mp3, or re-converting the files as .ogg as another copy,

Ubuntu :: Skipping The Authentication When Accessing And HDD?

Aug 7, 2011

On a laptop I have Windows 7 installed, and ubuntu 11.04. Now. A while ago the HDD died and I replaced it. with some data loss but nothing much to worry. Now I thought that it would be useful if I somehow could manage to direct the Documents, Music etc. etc. folders located /home/[user] to somewhere on a different partition HDD. I managed to make new folders on the partition and link them with the documents and music folders etc.. the problem now is is that you have to unlock it every time by either opening the partition and insert your password. I know that the password problem can be evaded by simply changing some settings, but. I want to evade the whole process of clicking on the partition. It is for security reasons that that have to sort of activate the partition, but I find it becoming a bit annoying.

So, has anyone a clue of how to activate the driver right at the start? something automatic stuff. Or does someone know how to disable this ?

Ubuntu :: Skipping Encrypted Disk At Boot?

Jul 18, 2010

Ive managed to screw up an encrypted disk experiment, basically at boot i get ask to enter my password which i lost.

Only a data partition is encrypted, the linux system is unecrypted.

However, the skip option thats presented that should work via S does not work. every key in input adds one * behind the password prompt.

The password prompt changes from white to red though. as if in the white phase you should be able to skip.

Im to lazy at the moment to swap the drive and comment the drive in fstab

I already booted in single, but still the mount occours. is there another way to get the system booting?
