Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia. Get Hard Drive model ManagementObjectSearcher searcher = new ManagementObjectSearcher(“SELECT * FROM Win32_DiskDrive”); foreach(ManagementObject wmi_HD in searcher.Get()) { HardDrive hd = new HardDrive(); hd.Model = wmi_HD[“Model”].ToString(); hd.Type = wmi_HD[“InterfaceType”].ToString(); hdCollection.Add(hd); } Get … Read more
Linux As you suggested, fcntl is the way to do this on Linux. The C code you want to translate looks like this: static struct hd_driveid hd; int fd; if ((fd = open(“/dev/hda”, O_RDONLY | O_NONBLOCK)) < 0) { printf(“ERROR opening /dev/hda\n”); exit(1); } if (!ioctl(fd, HDIO_GET_IDENTITY, &hd)) { printf(“%.20s\n”, hd.serial_no); } else if (errno … Read more
This is the dreaded un-interruptible (TASK_UNINTERRUPTIBLE) state of a process. This is the state where the process doesn’t react to signals until what it started to wait for, gets done. Unfortunately it is a necessary evil. See here and here What is an uninterruptable process?. My answer is to reboot the system. Do rebooting cause … Read more
Finally a reliable solution! Two of them, actually! Check /sys/block/sdX/queue/rotational, where sdX is the drive name. If it’s 0, you’re dealing with an SSD, and 1 means plain old HDD. I can’t put my finger on the Linux version where it was introduced, but it’s present in Ubuntu’s Linux 3.2 and in vanilla Linux 3.6 … Read more
The ENOSPC (“No space left on device”) error will be triggered in any situation in which the data or the metadata associated with an I/O operation can’t be written down anywhere because of lack of space. This doesn’t always mean disk space – it could mean physical disk space, logical space (e.g. maximum file length), … Read more

For Python 2 till Python 3.3 Notice: As a few people mentioned in the comment section, this solution will work for Python 3.3 and above. For Python 2.7 it is best to use the psutil library, which has a disk_usage function, containing information about total, used and free disk space: import psutil hdd = psutil.disk_usage(“https://stackoverflow.com/”) … Read more
I found this nugget at the link following. It worked perfect for me and only took 5 seconds. As of VirtualBox 4 they added support for expansion. VBoxManage modifyhd filename.vdi –resize 46080 That will resize a virtual disk image to 45GB. https://superuser.com/questions/172651/increasing-disk-space-on-virtualbox
