Can Windows tell me what is using my USB drive? - Super User
Saved by uncleflo on January 16th, 2022.
Connect and share knowledge within a single location that is structured and easy to search. Being the good citizen I am, I left-click on the "Safely Remove Hardware" icon in my taskbar, and select my USB drive to dismount. Then I get the message: Windows can't stop your Generic volume device because it is in use. Close any programs or windows that might be using the device, and then try again later. Of course, being the Operating System, it knows exactly what applications are using my device. So why won't it tell me? Or is there a way that I can find out?

Three-phase commit protocol
Saved by uncleflo on October 12th, 2016.
In computer networking and databases, the three-phase commit protocol (3PC)[1] is a distributed algorithm which lets all nodes in a distributed system agree to commit a transaction. Unlike the two-phase commit protocol (2PC) however, 3PC is non-blocking. Specifically, 3PC places an upper bound on the amount of time required before a transaction either commits or aborts. This property ensures that if a given transaction is attempting to commit via 3PC and holds some resource locks, it will release the locks after the timeout.

Grub2
Saved by uncleflo on March 28th, 2016.
GRUB 2 is the default boot loader and manager for Ubuntu since version 9.10 (Karmic Koala). As the computer starts, GRUB 2 either presents a menu and awaits user input or automatically transfers control to an operating system kernel. GRUB 2 is a descendant of GRUB (GRand Unified Bootloader). It has been completely rewritten to provide the user significantly increased flexibility and performance. GRUB 2 is Free Software.

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

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

Saved by uncleflo on August 9th, 2014.
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.

ddrescueview | Free software downloads at SourceForge.net
Saved by uncleflo on August 9th, 2014.
This small tool allows the user to graphically examine ddrescue's log files in a user friendly GUI application. The Main window displays a block grid with each block's color representing the block types it contains. Many people know this type of view from defragmentation programs. The program is written in Object Pascal using the Lazarus IDE. It can be compiled to run on Windows, GNU/Linux and probably OS X, too. The downloads include binaries for the respective target platform and the project files (source code).

Ddrescue - GNU Project - Free Software Foundation (FSF)
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..?

extundelete: An ext3 and ext4 file undeletion utility
Saved by uncleflo on August 9th, 2014.
extundelete is a utility that can recover deleted files from an ext3 or ext4 partition. The ext3 and ext4 file systems are the most common default file systems in Linux distributions like Mint, Mageia, or Ubuntu. extundelete uses information stored in the partition's journal to attempt to recover a file that has been deleted from the partition. There is no guarantee that any particular file will be able to be undeleted, so always try to have a good backup system in place, or at least put one in place after recovering your files!

Deleted or lost files can sometimes be recovered from failed or formatted drives and partitions, CD-ROMs and memory cards using the free/libre software available in the Ubuntu repositories. The data is recoverable because the information is not immediately removed from the disk. Follow these steps to recover lost data.

10 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
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.

Managing KVM-LVM based virtual machines: backups, cloning, and more
Saved by uncleflo on July 24th, 2013.
This is a small follow up to my previous post on Setting up a KVM-LVM based virtual machine host, so if you haven't set up a KVM virtual machine host yet, you may want to read that post first. In the previous post I've described how to set up a very simple virtualised environment based on KVM. I also mentioned that I usually do part of the administration with the bundled GUI, virt-manager, and that I use command line tools for those administration tasks that aren't available in the GUI; in this post I'll mention some of the ones I happen to need most often.

In this doc we explain how to put clonezilla live in your harddrive which already has an OS installed. Here we use grub boot loader as an example. You have to put the clonezilla live files in a FAT, ext2/3, reiserfs or any grub supported partition. If you do not have such a partition, you can use gparted to resize your partition and create another partition to put clonezilla live. Here we assume you already have a FAT partition /dev/sda4 to put clonezilla live.

Making An NTFS USB Boot Disk | Bjorn3D.com
Saved by uncleflo on January 20th, 2013.
This morning when I got up I had no intention of writing a guide to making a bootable NTFS USB Drive. As things often happen on a review site you often find yourself waking up intending to get one thing done and end up going in a totally different direction. Today was one of those days. I’ve been dealing with SSD, Platter hard drives and USB Drives all week. Suddenly this morning I found myself thinking wouldn’t it be nice to be able to boot to a USB disk with the NTFS file system and run diagnostics, memory tests, and maybe install Vista or XP from a USB disk. How about being able to not only install Vista from a USB disk but once Vista is installed have all the review benchmarks and files I needed consolidated on one flash drive instead of searching for a bunch of disks scattered around my review area.
