Best codec for game, video and screen recording - Bandicam

https://www.bandicam.com/support/tips/best-codec/

Saved by uncleflo on January 6th, 2019.

What is the best video codec for game recording, video recording, and screen recording? If you use a high-compression codec, you can get a small video file, but the encoding speed might be slower. If you use a high-quality codec, you can get the best quality video, but the video file size might be larger. If you use a high-speed codec, you can reduce CPU usage, but the video file size might be larger. So, you have to choose the best video codec by yourself to meet your recording needs.

SpaceSniffer - Visualizing Layout Disk Space

http://www.uderzo.it/main_products/space_sniffer/download.html

Saved by uncleflo on December 20th, 2018.

SpaceSniffer is a freeWare (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks. By using a Treemap visualization layout, you have immediate perception of where big folders and files are placed on your devices. Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool. Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content. Need more and more detail? Keep selecting elements and they'll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it'll zoom to the full extent of the view. If you need to understand why no more free space is left on media, keep following bigger elements. Maybe you want to focus only on particular file types... ok. Just type the file type on the filter field (example: *.jpg) and press enter. The view will react and show you only JPEG files.

filesystems - recovering ext4 partition after dd'ing over start of HD - Unix & Linux Stack Exchange

http://unix.stackexchange.com/questions/46914/recovering-ext4-partition-after-dding-over-start-of-hd?s=3b3d8f577c8d415290eccb47b3cb923d

Saved by uncleflo on August 9th, 2014.

I accidentally used dd and wrote over the first 208MB of my external disk. What I wrote over is a partition on its own (Debian nestinstaller) so what I see now is not my old (now damaged) ext4 partition but another smaller partition. This limits the tools and advices I could follow. My plan was to recreate the partition table with testdisk and then fix everything with the backup superblocks as described here. I'd lose the first 208MB but that's ok compared to the other 300GB of data in there. Something like the following:

How to recover ext4 from GPT partitioned disk - Information Technology

http://howto.tipit.info/pc/linux/104/how-to-recover-ext4-from-gpt-partitioned-disk/

Saved by uncleflo on August 9th, 2014.

Hard drive sizes had increased dramatically in last several years, but block device drivers are still outdated. For hard drives more than 1TB currently seems to be an advantage to use GPT instead of legacy MBR partition table. You can see more details at http://en.wikipedia.org/wiki/GUID_Partition_Table. One of the inevitable disadvantage of GPT is the possibility of corruption by using outdated partition editor like cfdisk, or other disk tools, even without any intention to modify the partition. It happened recently on one 1.5TB WD Caviar Green with GPT and one ext4 partition full of data.

HOWTO: Repair a broken Ext4 Superblock in Ubuntu « Linux Expresso

Saved by uncleflo on August 9th, 2014.

This has happened to me a few times, and it’s not a nice problem to find yourself in. You computer won’t boot, all your filesystem checks tell you you’ve a bad superblock, but you cant seem to find how to fix it. Well, here goes :) This guide is for ext4 , though I’ll explain how other filesystems can be cured along the way. The easiest way to carry all this out, seeing as your computer probably won’t boot at this stage, is to download and burn a copy of Parted Magic. Boot from that, and you’ll access to a number of useful tools.

Kpartx: a tool for mounting partitions within an image file | Robert Penz Blog

http://robert.penz.name/73/kpartx-a-tool-for-mounting-partitions-within-an-image-file/

Saved by uncleflo on August 9th, 2014.

Kpartx can be used to set up device mappings for the partitions of any partitioned block device. It is part of the Linux multipath-tools. With kpartx -l imagefile you get an overview of the partitions in the image file and with kpartx -a imagefile the partitions will accessible via /dev/mapper/loop0pX (X is the number of the partition). You can mount it now with mount /dev/mapper/loop0pX /mnt/ -o loop,ro. After unmounting you can disconnect the mapper devices with kpartx -d imagefile.

This situation might not affect everyone, but it struck me today and left me scratching my head. Consider a situation where you need to clone one drive to another with dd or when a hard drive is failing badly and you use dd_rescue to salvage whatever data you can.

Ddrescue - GNU Project - Free Software Foundation (FSF)

http://www.gnu.org/software/ddrescue/ddrescue.html

Saved by uncleflo on August 9th, 2014.

GNU ddrescue is a data recovery tool. It copies data from one file or block device (hard disc, cdrom, etc) to another, trying to rescue the good parts first in case of read errors. Ddrescuelog is a tool that manipulates ddrescue logfiles, shows logfile contents, converts logfiles to/from other formats, compares logfiles, tests rescue status, and can delete a logfile if the rescue is done. Ddrescuelog operations can be restricted to one or several parts of the logfile if the domain setting options are used. The basic operation of ddrescue is fully automatic. That is, you don't have to wait for an error, stop the program, read the log, restart it from a new position, etc. If you use the logfile feature of ddrescue, the data is rescued very efficiently, (only the needed blocks are read). Also you can interrupt the rescue at any time and resume it later at the same point.

partitioning - How to recover partially formatted ext4 partition (testdisk did not help) - Ask Ubuntu

Saved by uncleflo on August 9th, 2014.

I have а 2TB "single ext4-formatted partition" HDD. Recently, while working under Windows 7 on the same machine, I have damaged the aforementioned partition. What happened is that while I was trying to recover external USB drive I opened standard windows disk-management tool and it prompted me if I want to make disk1 "active". At that moment I didn't realize that "disk1" is not my USB disk, but the ext4 internal disk. After clicking OK, windows has created 100 MB "system reserved partition" on the disk and left the rest untouched..?

PhotoRec - Digital Picture and File Recovery

http://www.cgsecurity.org/wiki/PhotoRec

Saved by uncleflo on August 9th, 2014.

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. PhotoRec is free - this open source multi-platform application is distributed under GNU General Public License (GPLV v2+). PhotoRec is a companion program to TestDisk, an application for recovering lost partitions on a wide variety of file systems and making non-bootable disks bootable again. You can download them from this link. For more safety, PhotoRec uses read-only access to handle the drive or memory card you are about to recover lost data from.

Persistent block device naming - ArchWiki

https://wiki.archlinux.org/index.php/UUID#by-uuid

Saved by uncleflo on August 31st, 2013.

This article describes how to use persistent names for your block devices. This has been made possible by the introduction of udev and has some advantages over bus-based naming. If your machine has more than one SATA, SCSI or IDE disk controller, the order in which their corresponding device nodes are added is arbitrary. This may result in device names like /dev/sda and /dev/sdb switching around on each boot, culminating in an unbootable system, kernel panic, or a block device disappearing. Persistent naming solves these issues.

initrd - Linux Command - Unix Command

http://linux.about.com/od/commands/l/blcmdl4_initrd.htm

Saved by uncleflo on August 31st, 2013.

The special file /dev/initrd is a read-only block device. Device /dev/initrd is a RAM disk that is initialized (e.g. loaded) by the boot loader before the kernel is started. The kernel then can use the the block device /dev/initrd's contents for a two phased system boot-up. In the first boot-up phase, the kernel starts up and mounts an initial root file-system from the contents of /dev/initrd (e.g. RAM disk initialized by the boot loader). In the second phase, additional drivers or other modules are loaded from the initial root device's contents. After loading the additional modules, a new root file system (i.e. the normal root file system) is mounted from a different device.

10 fdisk Commands to Manage Linux Disk Partitions

http://www.tecmint.com/fdisk-commands-to-manage-linux-disk-partitions/

Saved by uncleflo on August 30th, 2013.

fdisk stands (for “fixed disk or format disk“) is an most commonly used command-line based disk manipulation utility for a Linux/Unix systems. With the help of fdisk command you can view, create, resize, delete, change, copy and move partitions on a hard drive using its own user friendly text based menu driven interface. This tool is very useful in terms of creating space for new partitions, organising space for new drives, re-organising an old drives and copying or moving data to new disks. It allows you to create a maximum of four new primary partition and number of logical (extended) partitions, based on size of the hard disk you have in your system.

How do i know the BIOS number for my SCSI disks

http://www.tldp.org/HOWTO/LILO-6.html

Saved by uncleflo on August 30th, 2013.

The contribution from Marc Tanguy (mtanguy@ens.uvsq.fr), 2001-09-27. If you have an adaptec scsi card (2940u2, 29160, 39160), you simply use the 'diagnose' mode (using BIOS v3.10.0 recommended). It must be activated in the scsi card BIOS menu. If you don't own an adaptec card, you have to know what is the 'booting' disk (usually ID 0, but not necessary, it can be defined in the scsi card BIOS) where LILO is going to be found and start : this is the first disk so it has number 0x80. Then it's very simple, the BIOS follows the IDs.

dd is a wonder allowing you to duplicate a hard drive to another, completely zero a hard drive, etc. But once you launch a dd command, there's nothing to tell you of it's progress. It just sits there at the cursor until the command finally finishes. So how does one monitor dd's progress?
