Warning: This workaround is for advanced users only. This workaround involves using a disk sector editor to modify the media descriptor byte on the floppy disk. Misuse of a disk sector editor may make all the data on the drive or volume permanently inaccessible. Disk sector editors function at a level "below" the file system, so the typical checks for maintaining disk consistency do not apply. This provides you direct access to every byte on the physical disk regardless of access credentials. Therefore, you can damage or permanently overwrite critical on-disk data structures. Use this workaround at your own risk.To work around this problem, use a disk sector editor to change the BPB media descriptor byte to the appropriate value. For example, you can use the DiskProbe tool to do this on a Windows NT 4.0-based, Windows 2000-based, Windows XP-based, or Windows Server 2003-based computer. DiskProbe (Dskprobe.exe) is included with the Windows Support Tools for Windows XP Professional and Windows XP 64-Bit Edition, the Windows 2000 Support Tools, and Windows NT 4.0 Resource Kit Support Tools.The following table lists the most common media descriptor bytes: Byte Capacity Media Size and Type ------------------------------------------------- F0 2.88 MB 3.5-inch, 2-sided, 36-sector F0 1.44 MB 3.5-inch, 2-sided, 18-sector F9 720K 3.5-inch, 2-sided, 9-sector F9 1.2 MB 5.25-inch, 2-sided, 15-sector FD 360K 5.25-inch, 2-sided, 9-sector FF 320K 5.25-inch, 2-sided, 8-sector FC 180K 5.25-inch, 1-sided, 9-sector FE 160K 5.25-inch, 1-sided, 8-sector FE 250K 8-inch, 1-sided, single-density FD 500K 8-inch, 2-sided, single-density FE 1.2 MB 8-inch, 2-sided, double-density F8 ----- Hard disk The BPB media descriptor byte is located in sector 0 of the disk, and looks similar to this: addr data: 0000 EB 3C 90 4D 53 44 4F 53 35 2E 30 00 02 01 01 00 0010 02 E0 00 40 0B F0 09 00 12 00 02 00 00 00 00 00 xx

Use the WODselect retrieval system to search the WOD by specific parameters (date, geographic area, probe type, etc.) and measured variables. View a dataset distribution map and cast count of your search criteria, and download a custom dataset in WOD native, csv, or netCDF.
To run DiskProbe, first download the Windows Support Tools from Microsoft (to find them, visit www.microsoft.com and search for "Windows Support Tools Download") or locate the tools on the Windows installation CD (they are normally in the \SUPPORT\TOOLS folder on the CD) and install them. Once the tools are installed, select Start, Windows Support Tools, and Command Prompt. At the prompt, enter Dskprobe. The program will then launch in a window. Optionally you can run the program by opening Windows Explorer and navigating to the \Program Files\Support Tools folder, and then click on Dskprobe. The documentation for the program is available via the Help command on the menu bar.
If you are wondering where all your disk space has gone, you should check your computer for large files. Most Internet users download many files (such as videos, music, and images) on a daily basis. Some of these files might be large and occupy gigabytes of disk space.
The first thing to do is to detect the partition where your data are located.Linux uses names that are different from windows for the disks, so you will seenames such as /dev/sda1, /dev/sda2 instead of C: or D:.To detect the disks and partitions, just run the following command:fsarchiver probe simple. You should see an output such as:
