I have a computer with 2 hard disks. One hard disk has only a Windows 7 partition. The other one has multiple partitions with multiple Windows operating systems, i.e. Windows 2003, Windows 7, Windows Vista and Windows 2008.
All of sudden, all Windows operating systems except the Windows 2003, on this computer on both hard disks, reported the sizes of all partitions reduced from 20GB and 90GB to 500MB. So some partitions have run out of space. The Windows Explorers and top part of the Computer Management all make such mistakes. The bottom part of the Computer Management reports correctly. Booting from an install disk, the report of the disk sizes on the GUI is still wrong. However, checking with the diskpart command on its command prompt they are all correct. Chkdsk doesn’t find any problem. However Windows 7 partition cannot disable any service or startup item while running normal mode. The sfc /scannow would not run. Nevetheless running in safe mode all the operating systems report everything correctly. Windows 2003 operating system always reports correct partition sizes.
On the latest operating systems, it is not only reporting problem. I can’t do anything because there is allegedly no free space left. Some programme would not run. Internet is okay.
I wonder if malware can wreak such havoc on multiple partitions on two different hard disks at the same time.
