hard-drive

问题 I've been going around in circles for a bit now, can't seem to find the answer on google either. As the title says, if i get the current drive letter windows is running on, let's say like this: Path.GetPathRoot(Environment.GetFolderPath(Environment.SpecialFolder.System)); Can i then determine its Win32_DiskDrive SerialNumber? I cannot find a way to link them. That is the manufacturer's S/N not the VolumeSerialNumber. Thanks in advance 回答1: You can use ManagmentObjectSearch combined with

问题 Does anyone know of a way to issue commands to a hard drive within Java? Does Java even support this kind of hardware interaction? For example, if I have a SCSI hard drive that I would like to inquiry, is there a pre-existing Java method to do this, or would I have to write my own? http://en.wikipedia.org/wiki/SCSI has some general information on SCSI commands in case you aren't familiar. 回答1: Java doesn't support talking directly to hardware like that. However, you can use JNI to call a C/C+

问题 Recently after a couple of power outages, my computer has gotten quite messed up (BSODs every now and then, entire OS behaves really strange). Now I have a program that ran perfectly fine before my computer got messed up. This program just basically creates a file using CreateFile and writes to it using WriteFile. This program also has other stuff doing their thing based on this file. I noticed that the entire program acted strangely as well. My debugging results: I noticed that after

问题 I need to do a complete format on a USB stick (FAT16 or FAT32), put a file on the drive, then delete it and recover the file using a C program. Could anyone give me a hint on what should I use to accomplish this? I understand the layouts of the FAT16/32 filesystems, the problem is that I don't know how to access the raw HD data using C (since I can't use things like fopen or mmap because the file isn't there anymore). 回答1: This is highly operating system specific. For Linux, you would open

问题 Background: Assume I use the following powershell script from my local machine to automatically map some network drives. $net = $(New-Object -ComObject WScript.Network); $net.MapNetworkDrive("p:", "\\papabox\files"); $net = $(New-Object -ComObject WScript.Network); $net.MapNetworkDrive("q:", "\\quebecbox\files"); ## problem -- this one does not work because my username/password ## is different on romeobox $net = $(New-Object -ComObject WScript.Network); $net.MapNetworkDrive("r:", "\\romeobox

问题 I have a 2TB hard drive full of backed up data, including hundreds of movies, most of which have been copied several times due to sequential back-ups of the same HD. The hard drive is organized as a list of back-up folders, and every back-up contains a movies folder that has all the movies that were on my laptop HD at the time of the back-up. I'd like to create a new movies folder and move all movies from every "movies" subfolder into the new one, making sure not to move the same movie twice.

问题 I need to map Boot Manager to a partition number: Manufacturer Recovery partition = Partition 0 Boot manager = Partition 1 C:\ = Partition 2 D:\ = Partition 3 For mounted partitions, like C:\ or D:\, I use IOCTL_STORAGE_GET_DEVICE_NUMBER to retrieve partition numbers. Now I would like to do something similar to get the number of the Windows Boot Manager. I can't assume that the BootMgr is the 100 MB partition or the previous to the System partition. I have had a look to IOCTLs related to disk
