Though it's working as advertised, it doesn't restore automatically on wake-up, here on PPC 10.5.8, so you have to go to the pref and restore it manually. Also, though the self-restore at session start works, you have to do the back-up manually through the prefpane when you close it... It would have been nice if it was a totally transparent process, but for my use, sleeping and waking multiple times a day, it would be too much of a hassle.

Sorry for the triple posting below. When I first tried posting I mistakenly posted to reviews, then on trying to post to troubleshooting I got an error, so I tried again. Then when I found an address to send the problem to, and tried again so I could relay the exact error message, well, there are now three postings. again sorry

When I wake from sleep, I see the RAMDisk icon on the desktop, but it soon goes away. It does not then show up as a drive in DiskUtility or anywhere else. I have developed the problem I think after upgrading to 10.6.6 (from 10.6.5).

Absolutely PERFECT running under OS X 10.6.4! That Apple does not offer this capability bewilders me. This is far far better than using a terminal script that will create a Ram Disk: Buried in the manual pages for Apple's command-line disk-image-management utility "hdid" are a few instructions on how to use this command to create and mount a RAM disk. The process basically involves creating a mount point for the disk, using the hdid command to allocate the RAM for the disk, and then create a file system on the disk so it can be used and mount it to the mount point. #!/bin/sh

NUMSECTORS=128000
mydev=`hdid -nomount ram://$NUMSECTORS`
newfs_hfs $mydev
mkdir /tmp/mymount
mount -t hfs $mydev /tmp/mymount Copy this text to a plain text document (not rich text) in TextEdit, and save it with ".sh" as the filename suffix (i.e., "ramdisk.sh"). Then open the Terminal and type "chmod u+x " followed by a single space, drag the script file to the Terminal window, and press enter. This will enable execution of the script by the owner of the file (you). After this is done, to run the script just open a Terminal window, drag the script to it, and press enter. The default value for "NUMSECTORS" in the script will give you a 64MB RAM disk, but you can increase this number if you would like. The number represents sectors, and there are 512 bytes per sector of RAM. To edit the script after it has the .sh filename suffix, right-click it and choose TextEdit under the "Open With..." menu. You can also run a similar script in one line using Apple's "diskutil" and "hdiutil" commands, which result in a more user-friendly RAM disk than the previous script. diskutil erasevolume HFS+ "ramdisk" `hdiutil attach -nomount ram://128000` When run in the Terminal, this command does a number of things (note the single quotes are actually "grave accent" marks). First it invokes "hdiutil" to attach an allotment of RAM but not yet mount it since there is no filesystem on it yet. After the RAM is allotted, it calls on the "diskutil" command to format the allotted RAM and name it "ramdisk," which will cause the Finder to mount it under that name in the default mount point /Volumes/. This may be a preferred method because it is simpler and allows you to name the disk by changing the "ramdisk" name in the Finder.

The comment below is misleading. It looks to me the RamDisk size can be quite large, at least 1/2 of physical RAM. The slider starts at 16 MB, it doesn't end there.

This is a question for Michael Parrot. Is there a way to create a RAM Disk larger than 16 MB if I have 4.5 GB of RAM in my Mac? (16 MB seems small for an upper limit). Thanks.

Cool little tool now that I have a pretty large amount of memory. Reminds me of the RAM: drive on the Amiga. Is there a way you could have the disk dynamically change size to the amount of free unused memory in the system? That way, you don't have to create a disk of a set size, it is just there and able to hold as much stuff as you have free ram...if the OS needs more memory, it takes it and the disk loses free space to the point that it is "full" if you have files copied in there. (Then it really would be like the RAM: drive on the Amiga.)

My hats off to an amazing little pref.pane that doesn exactly as it should, create a Ram Disk on the fly! I backup the ramdisk contents using DropDMG to create disk image of it, and just copy it's contents back onto the Ram disk as needed. So nice to have a super fast scratch disk again! And for free!!! Many thanks!!!!

Is there a way for the files inside the ram drive to stay after a shut down or restart? I really want to keep some specific programs/files in it but having to re-copy them every time is quite a hassle especially when i use those files often.

Be careful. The installer creates the prefPane with world-writeable permissions. You may want to run 'chmod o-w /Library/PreferencePanes/*' after installing it.

Works good for Safari cache. Unfortunately, unlike in OS 9, the Seti@Home screensaver doesn't support moving its data files to another location (i.e. to a RAM disk) using a folder alias (or a symlink), but obviously this is not Esperance's fault. Generally, I had some troubles to change the settings in Esperance DV. I had to delete the disk image manually and log out and in a couple of times until it did what I wanted... But that's okay, it's free after all.

Anyone care to explain what this is used for to someone that doesn't quite get it? I understand using RAM as storage space but why do you need to get to these files? Doesn't X Code take care of everything it needs to do? I'm just curious. I'm assuming its one of those "if you dont know then you dont need it" things.
