disk-partitioning

问题 After lots and lots of try and error I am now able to flash/write a raw image file (containing multiple partitions) to \\.\PhysicalDriveN (SD-Card in my case) by just using Windows Api calls ( see below ). But as soon as I have some explorer windows open and click around, the write process fails ( error 433 ). Another annoying problem are popup messages telling me that a new volume has to be formatted (at the beginning, while I am still writing!) or autoplay asks me to select an action (after

问题 When I run this on the command line it works fine: echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb But in Ansible it does not want to run in shell: - name: partition new disk shell: echo -e "n\np\n1\n\n\nw" | sudo fdisk /dev/sdb It does not come back with an error, but it does not create the partition either. I checked that Ansible and LVM will not do what I need. Any advice? 回答1: By default, Ansible executes /bin/sh shell. For example, if /bin/sh is linked to dash , it's built echo is

问题 I have to write a code to access hidden disk partitions/volumes using c# or c++. But could not find any help reference on the matter. As a hidden volume, it does not contain a "Disk Letter", so you can´t just type "C:\" and access it. A example would be the "recovery partition" that comes with Windows. You can´t see it on explorer but it is there. My application will write and read data from thoose partitions and I have to find a way of doing something like "c:\" for thoose. In the above

问题 Is there a way to get disk partition and volume information using Java libraries only? I also need deleted file information. Disk is formatted as a FAT-16 and has standard MBR. I need the following information: a) Partition information - Display the number of partitions on the disk and for each partition display the start sector, size of partition and file system type. b) Volume information – For the first partition only, display the number of sectors per cluster, the size of the FAT area,

问题 I am writing a PowerShell script that will back up several folders from my Vista drive to an external USB drive, using robocopy. Windows does not guarantee that it will always assign the same drive letter to the external drive. What is the best way to get around this problem? How do I code the destination paths? Thanks. 回答1: Windows could change that drive letter assigned to your USB drive. The correct way to do this backup is mounting the USB drive in an empty directory. Not only does it add

Accessing a raw disk partition in Windows Vista requires kernel mode control, as opposed to for instance WinXP where you can access it from user mode. However, I've heard that when it comes to USB flash memory, a partition can still be accessed from user mode even on Windows Vista. Is this true? Regards /Robert
