What's taking up almost 25% of ramdisk?

I just created a 64 MB dynamic ramdisk on my work laptop and noticed this:

Just curious -- what is consuming that 13.5 MB of space?

NTFS filesystem files?

Only a guess, for some reasons I cannot see the image you linked to.

Oh, interesting. I've used FAT32 with other ramdisk software in the past, but with ImDisk I decided to stick with the default NTFS option and was surprised to see it consume so much space (if that's the reason).

For some reasons I cannot access properly imgur.com.

 

But I don't need to, my guess was right  :smiling9: .

 

Now do this experiment.

 

Get DMDE:

https://dmde.com/download.html

 

Use it to open the volume (logical disk) corresponding to the IMDISK drive letter.

 

Then on left pane click on Metadata, in the right panel you will see the NTFS fileystem files (and their size).

 

Now do another experiment, create in IMDISK a new volume, 2525 Kilobytes in size and format it in NTFS (use default values).

 

Now open a command prompt and run CHKDSK on it, you will see how you have:

2524 KB total
2485 used by system

35 KB available

 

The culprit is largely the $LogFile that has a mimimum default size of almost 2 MB.

Thanks for the suggestion on using DMDE, however my work laptop is locked down pretty tight (I'm stuck with a standard account), so I'm not able to run this tool :( (I had to submit a ticket for an IT person to remotely install ImDisk for me). The screenshot shows that on a newly created 64 MB ramdisk, 13.5 MB is used space and 50.4 MB is free space. Since I don't plan to index or enable File History for this drive, I think I should've formatted it as FAT32.

64 MB FAT32?

 

If your scope is to have the least filesytem overhead, try FAT16.

 

You don't really-really need DMDE (if you need not the details) CHKDSK, as said, will tell you how much (globally) is "in use by system"
