Mirrored drive

by blackcurrant . Updated 24 years, 9 months ago

One of my colleagues is using a system with W95b, 32Mb RAM with a Pentium (r). Several months ago he had installed Norton Utilities 2000 with all the bells and whistles onto his hard drive. He found, however, that the system was slower and that NU had taken control of the recycle bin etc. During one boot-up NU DiskDoctor identified problems with his hard drive and presented a series of questions. My colleague kept pressing ‘Y’ automatically and once the process had finished decided to uninstall NU.

The problem is this: after uninstallation he noted that he had an additional drive – D: This drive is a mirror of C: – delete or add files or folders to C: and the action is mirrored on D: He has even deleted the entire contents of D: only to see it reappear after the next boot-up. The drive can be accessed from My Computer and from a DOS-prompt. I ran FDISK which showed that the D: partition was exactly the same size as the C: partition.

I have checked the BIOS (AMI), autoexec.bat, config.sys, win.ini, system.ini, the startup folder and the HKLM and HKCU paths in the registry for any program that may be initiating the mirroring process and have drawn a blank. As far as I am aware Norton Utilities does not have a mirror utility.Also, this machine has up-to-date anti-virus software running all the time, so the drive does not appear to be the result of any digital nastiness.

I do not understand how the data is being replicated. Does anyone know what is happening? If anyone requires further details please ask. I intend to delete the partitions and reinstall the OS soon, as the current OS has resided on the drive for several years, and could do with a tidy-up, but I would like to know how the extra drive has appeared.
Thanks

Mark
