Problems with mounting a drive

Posted on 2001-06-26

Server is running Win2k Server SP2. All volumes are located on dynamic disks. I have assigned one volume (3.68GB) the drive letter g and created a shared folder in their called g:\videos. I then used disk management to mount another 3.69GB volume into the folder g:\videos. Worked fine except that G:\shows up with only 3.68GB of space and when i tried to copy 5.8GB of mpeg files to g:\videos the computer had a fit. It brought up a message that the files had 150382mins remaining to copy, went on for a while and then stopped with an error about not enough space.

If you mount a drive in a directory, it's free space will only show up when you are in that specific directory. This can be well seen in a Command Prompt using DIR; if you do a DIR on the host drive, it will rreturn another value for the free space than if you do this in the mounted directory.

A mounted directory SUBSTITUTES a drive, but does not ADD space to another drive. So, if I have a 80GB C: drive and mount a 2GB drive in the dir C:\MOUNT, I will have only 2 GB of total space in C:\MOUNT, no matter how much is left on the large disk.

Explorer often shows completely wrong extimated times on large files. This apparently is an overflow when calculating the estimated time and does not have anything to do with the problem you're experiencing.

A solution may be this:

G:\VIDEOS\PART1 -> normal dir (3.68 GB)
G:\VIDEOS\PART2 -> mounted 2nd drive (another, independent 3.68 GB)

This allows you to have all your MPEG files in that one share by splitting them up in two dirs...

Thanks. I realise what i had done wrong straight after posting. However my solution wasn't as good as yours....I ended up creating a Raid0 volume from disk management. Still confused explorer. Hows this for Win2k math free space 7.64 GB, used space 7.3GB, total space 7.64GB

Thanks for the feedback, tobyk. If you hit refresh (F5), is the math still wrong in Explorer?
