Need help in finding a tool to fill up Disk Space.
      #719301 - 11/05/12 08:53 AM

Hi all,
I have a requirement to test the application behavior with specific disk space left on local drive. Tried a lot on internet, but did not find any reliable tool.

Basically this is what I want the tool to do:
--Identify the local drives like C: or D: etc..
--Identify space the disk capacity. Example: Space left, actual disk space.
--User shall be able to hold the specific amount of disk space on a particular drive. After the test is done -Free up the space help.

It would be great help if you suggest me any tool.

Thanks in advance,
Gary

Hi Joe, thanks for the prompt response. I looked at the link further blogs. Lot of them talk about system maintenance tools- things to clear up junk from disk. Things which system mechanic tools would do.

But, I am looking for a tool which can Hold or Release of disk space as user requests. For example by writing a huge file to the drive. OR by fooling around windows to think its C drive (or any Drive) is full.

Easy programmatic solution. All you need to do is to write a small program which uses a block of non-compressible data and write a file of a particular length, or (in a directory) write several hundred files which add up to your total allotment on the drive. At the end of your test run another program written by you to clean up the files.

Whenever I've had to do this, I usually used a VM with a particularly small C: or D: drive.

Way back before I used VMs, I'd simply copy large files either manually, or via a script.

But if you really need a tool, a quick Google search turns up

@ James, thanks for the suggestion. I will work on it. Probably its a long term solution for me now.

@ Joe, thanks a ton for helping. After deeper research, I landed up with the same tools you pointed in the links. I will use the appropriate one and get the Test going for now. later write a program as James suggested.

I thought it will be helpful for someone, hence posting the simplest solution I found:

There is also a Windows utility that allows creation of a file of a given size:

Usage : fsutil file createnew <filename> <length>
Eg : fsutil file createnew C:\testfile.txt 1000

If you are working in a FDA or regulated environment, bonus is you need not validate this.

Because it's a Windows utility? Otherwise you would need to validate the method you used to fill up your hard disk?

Ya because its windows utility, we need not validate it. That's how it was explained to me. But, we do have validated Off shelf tools (automation tools to test our SW) and the tools we developed internally for testing purpose. But, we are not validating VSTS or TFS etc.

I would never have guessed that you would need to validate a tool used to chew up disk space.

I guess I'm glad I don't work in a regulated industry. I use a lot of little utilities and tools. I suspect "validating" each one would be quite a cottage industry.

I am new to Verification and Validation world. I may be wrong, but I share what I understood

Validation is testing whether the tools or the system has met the intended use.

Example: X ray device
Validation: User shall be able to take an X Ray image and send it electronically to the corresponding Provider. Basically validating that we have met user needs.

Verification: Software system shall provide a method to store X ray images an Archive.
OR System shall allow user to send messages to Provider.

Validation in this case means that the tool needs to be validated to comply with the requirements of the regulating agency before it can be used in the manufacture/development of a product in that industry.

Ok. Well I guess I'm not in a regulated industry because like Joe I use lots of different tools/utilities and have never validated any. I've never even heard of it before today. But thanks for explaining :-)
