RAM Disk in OS X
Is it possible to create a RAM disk in OS X like you could make in OS9?
Hi, SFD. Yes, it is:
http://www.clarkwoodsoftware.com/rambunctious/ramb2.html
http://www.donelleschi.com/ramdiskcreator/
I've never used either utility myself. In OS 9, I always designated a RAM disk (created at each startup with the very useful and convenient AppDisk) as the place for my web browsers to keep their caches. That insured that the caches would be cleared automatically every time I restarted my Mac. In OS X I almost never restart it, so that strategy wouldn't be of any value to me now, and I clear browser caches manually at regular intervals.
What do you envision using a RAM disk for in OS X? Not that it's any of my business; I'm just curious.

[SOLVED] Suspend to ram / disk not working in newer kernels
Hi all,
this puzzles me for a while:
My desktop system was able to suspend to ram / disk flawlessly in older kernels. It stopped working with 3.3. The suspend seems to work, the machine goes to standby. But when I try to resume, the machines is on but the screen stays black. Neither the console is working nor can I ssh into it. Only hard reset gets me out here
I did investigate and found many tips and hints which all led to nowhere. I even changed my filesystem back from btrfs to ext4 and my VGA module from proprietary nvidia to nouveau.
When this all failed I got to the idea to burn several install disks. One of the official 2011.08.19 (kernel 3.0.3) and one of the snapshots 2012.06.05_04-00-01 (kernel 3.3.7) and 2012.07.17_04-00-01 (kernel 3.4.4). I guess these can not be compromised by some hosed installation. I started one by one and issued the follwing command:
echo mem > /sys/power/state
which suspends the machine successfully in all three cases. With 2011.08.19 the resume is working but the other two fail. Some more info about the hardware:

This seems to be a kernel bug. Any input?

Last edited by Harey (2012-08-06 13:51:49)Another life-sign. The issue is still unsolved but I've come a little further. It seems to be a combination of more failures. The first one is USB hardware. I have a usb keyboard-mouse combo from Logitech (comfort cordless desktop). The USB bus does not wake up correctly when resuming from suspend. So my keyboard is unsuable. I put in a file /etc/pm/sleep.d/20_custom-ehci_hcd with the following content:
BUSES="0000:00:1a.7 0000:00:1d.7"
case "${1}" in
hibernate|suspend)
# Switch USB buses off
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/unbind
done
resume|thaw)
# Switch USB buses back on
for bus in $BUSES; do
echo -n $bus | tee /sys/bus/pci/drivers/ehci_hcd/bind
done
esac
The bus IDs were taken from /sys/bus/pci/drivers/ehci_hcd
When I start pm-suspend from a console (no X started) this seems to reanimate my keyboard while the screen stays black (with backlight on). I can type and reboot. Also I can ssh into the machine from my laptop.
Concerning the blank screen there seems to be a bug in both the proprietary nvidia modules as well as the nouveau driver. The nvidia folks have issued a new beta driver which seems to at least minimize the failures. This all concerns the nv50-family of nvidias cards. I have a GF8600GT which is one of these
I'll wait for this driver and then restart my testing. Until then - no suspend/hibernate
EDIT: Today's nvidia 304.32 is solving my issues - I can sleep again

Suspend to ram/disk stopped working overnight
My suspend to ram/disk used to work fine, but overnight, it stopped. It is not an update issue since, I was able to suspend after the last update. I decided to update today hoping that it is going to solve the problem, but the problem persist.
Here is what happens:
$ sudo pm-suspend
or
$ sudo pm-hibernate
The computer suspends faster than usual, as if it does not take the time to complete the suspend procedure. When I turn the computer on, it starts to boot instead of resuming from suspend. In the case of hibernate, this is clearly obvious. Normally it is suppose to take 10-30 s. to save the memory data to the swap, but this time the computer shuts fast (1-2s.), and I doubt that all the data is saved to swap.
Here are the logs for each case (/var/log/pm-suspend.log):

This seems to be too few information to pin point the exact cause of the problem.
What should I do to troubleshoot this problem ?My linux installation is actually on a harddrive using SATA on a desktop. I decided to remove this harddrive and put it into an external usb enclosure. I booted this linux installation on my laptop. When doing suspend, it works as it should, which let me think this is probably not a software issue.
If it is a hardware malfunction, which hardware malfunction can be responsible of an incomplete suspend procedure as described earlier? -
I have a half dozen DVD-Ram disks (from my now-dead DVR). They mount on the Desktop and I can see the contents (VRO and associated files). I am exploring the various Toast, Streamclip (etc.) options to play/rescue the files. Once that is done, how can I erase (and rewrite/reuse) the disks? Neither Toast 8 nor Disk Utility seem happy with formatting/erasing this media. Any ideas?
~ KeriAh,... makes sense. Thanks! And here's what it says [below].
So, it seems to say I cannot "erase" ... but I can "overwrite" (??), which is splitting a hair finer would have occurred to me.
Okay. Then, how would I "overwrite" the files -- what application could I use to do this? Toast? Other??

Can I allocate RAM as disk space- like the old 'RAM disk' back in the day
I've got 11 gigs of RAM, and Photoshop wants <4. Is there a way I can allocate some of the leftover RAM through the OS-- similar to the old 'RAM disk' back in the day? If I could, I could make it the primary scratch disk for Pshop and hopefully see a significant in-app speed increase.
I'm posting this as an OS question, not a Pshop question.
ThanksYou would need to search at VersionTracker or MacUpdate to see if there is a compatible utility for a ram disk. There were several such animals around but nothing more recent than 2008. They may still work, but no assurances that they do. Use with caution. Be sure to check that they are Intel compatible at the very least.

I had a hard time finnding info on RAM disks in OS X so I am posting it here for anyone it might help.
Mac OS X has the ability to create a RAM disk built in just like OS 9. Unfortunately, Apple decided to remove this feature from the GUI. Here is how to do it via the command line:
diskutil erasevolume HFS+ "RAM disk" `hdiutil attach -nomount ram://4629672`
This will create a 2.2GB RAM disk, which is the maximum size. If you want to create more than one replace the "RAM disk" with "RAM disk2", "RAM disk3", and so on.
If you don't like dealing with the command line you can use Esperance DV which is freeware. It also has some nice features like restoring at startup and automatically moving the Safari cache to the RAM disk.
Benefits:
Anything that uses a scratch disk will benefit form a RAM disk. Video and image processing times will be greatly improved. Rendering 3D objects will be much faster.
Any program that requires a lot of real-time disk access will benefit from faster seek times.
It reduces power consumption. If you watch a movie on a plane, put it on a RAM disk. It will save your battery life.
Security is improved. Anything on the disk at shutdown is gone forever, no need to wipe the disk.
Increases your hard disk life. The less you use your hard disks the longer they last. The more you use a RAM disk the less you use your hard disk. Hence, the more you use a RAM disk the longer your HD will last.
Risks:
It works like any other drive +so long as the computer is running+. If you lose power or shut down the machine you lose whatever was on the disk forever.
To state the obvious: it uses up some of your RAM.
Finally let me say there are a lot of technical details I left out in describing the benefits, none of which affect the basic points that RAM is faster, more secure, and uses less power than a HD.Slow down a bit and think this through.
CUPS on linux is nearly identical to CUPS on OS X - but there is no Mac-to-Mac Apple proprietary print sharing. Rather, on linux you are sharing the printer using standard printing protocols. Just like on the Mac (when using the standard protocols like Windows/SMB or IP printing), linux print queues expect postscript input. Try using a generic postscript driver from the mac.
And when you add the printer via Windows Printing or IP > LPD or IPP, you will need to know the queue name for that printer from the linux box. (one computer with one IP address can have multiple printers - so what's the additional address info to print to your desired printer? - queue name.)

Hi..
Installing the appropriate combo update may help this issue.

How do I install Firefox 7 on a ram disk in Windows 7 ?
Firefox automatically installs into my program files and will not let me change that. I have a permanent ram disk. I think that Firefox would run faster if I installed it on the ram disk.
That most likely won't make any noticeable different because Firefox loads the program files in memory after loading and the profile folder with all personal data is located elsewhere.<br />
It is usually writes that cause the most delays especially if anti-virus software is checking each write.
See Firefox Profile Folder:

DVD-RAM disk/ReadDV!- how to get into imovie
Hello
I have a dvd-ram disk with home movies on it, transfered from VHS. I want to get it into imovie to edit. I have DVDxDv. DVDxDV doesn't recognize the disk and the disk will not import into imovie. I read somewhere to get ReadDV! by software architecs. I did and installed corectly and it still isn't doing anything different that what was happening before I bought the software. Mac OSX opens the disk and sees the file, but when I click on the .vro file it asks which application I want to use to open it, and when I click on ReadDV it goes to the install folder with nothing lit up to use as an application. imovie is not lit up as a choice to open it and neither is DVDxDv. Tech Support at Softarc is gone for the day, hasn't answered emails I sent 2 days ago and I'd like to work on this over the weekend. THANK YOU!I downloaded MPEG streamclip and it does convert, but you have to buy a download from apple in order for it to finish a conversion. Thought you'd like to know. Here's what the user guide says: MPEG Streamclip supports MPEG-1 video, MPEG layer 1/2 audio, AC3/A52 audio and PCM audio. MPEG-2 video is supported in conversions, but for playback and export you have to buy the MPEG-2 Playback Component ($19.99) from Apple." It's never easy, is it?

Mounting RAM Disks as "-notremovable"
I am replacing my G5 (10.5) Xserve with a late 2008 Xserve (10.6). This server is primarily a web server, with a small amount of mail traffic.
I keep my 'webfolder' on a RAM disk. All of my pages are dymanic php/mysql, so they can't be cached. But reading from RAM is so fast, you'd never know it.
This is the command I used in 10.5 to create a 1 GB RAM disk at boot:
[code]/usr/sbin/diskutil erasevolume HFS+ "web-ram" `/usr/bin/hdiutil attach -notremovable -nomount ram://2200000`[/code]
Not the "notremovable", that flag makes the system treat the mounted disk image (or in this case, the RAM disk), like a real physical disk, and not a mounted disk image. When you use this flag, the ram disk will actually show up with a regular hard drive icon. Without this flag, it shows up as a white disk image.
But this flag doesn't work in 10.6. According to the man page, it's still there. But when I use it, I get permissions errors. I am using it with sudo (from the command line, or as root via lanuchdeamons). As I look closer at my errors, It appears that what might be happening is that the diskutil command is being run as root, but the hdiutil command inside of it, is not.
Anyway this is about more than just the icon. When the ram disk is mounted as a real disk, its harder to eject, which is good because it's my web folder and I don't want it going anywhere. AND when its mounted that way, I can use time machine to back it up. Which works out to be a great system for that.So I was originally suspecting that there was a problem with `hdiutil`, but now I'm starting to think (based partly on error messages) that `hdiutil` creates the disk ok, but newfs_hfs is unable to write to this disk to format it. But only when it's -notremovable.
I hope someone has any clues about this? It's quite a sticking point. -

Sorry for the basic question, but:
I'm following Apple's steps to get my iBook G4 to eject a stuck CD. In the instructions to reset the PRAM, it says:
Warning: Resetting the Power Manager on any PowerBook or iBook will permanently remove a RAM disk, if present, and all of its contents.
That doesn't mean it will erase my hard drive, does it? Not sure what a RAM disk is.
thanks,
davidThat doesn't mean it will erase my hard drive, does it?
It won't.
Not sure what a RAM disk is.
The RAM disk is a Mac OS 9 feature that enables part of the computer's RAM to be used as if it was an external drive or disk image. Unless you've used third-party software in Mac OS X to create one, you won't have it.

DVD-Ram disks won't mount on Dual 450 - help!
I've got a particular and pressing problem. I'm an audio engineer among other things. I have a lot of files archived temporarily on DVD-Ram disks from my old Dual 450. I have to retrieve some files pronto but suddenly the DVD-Ram disk won't mount. The drive spits out the disk as soon as I insert it. It will mount CDs but not these DVD-Ram disks. Please help. I need to back these up off of thse old disks. But more urgently I have pending sessions that require I get some files from these disks. This happens both under OS 9.1 and 10.2.8 the last revisions of this computer I did. But it used to work until a year or so ago.
I have so far repaired permissions, used Disk Warrior and sprayed around the dusty drive with compressed air. It seems that perhapos a mechanism is loose springing the disk out when it's not immediately recognized as a CD or DVD-R.
Help!Probably your best bet is to dismantle the drive and try manually cleaning the lenses, which has made a difference for some users.
Other option is to replace the drive with a new one capable of reading (but not necessarily writing) DVD-RAM media. LG-4163B is one such drive, Pioneer DVR-110 can also read DVD-RAM. These drives are under $40 online in the US. -
Hi.
I am looking for information about RAM disks. How big they are, costs, performance etc. Where can i find such information. Is there somebody here, which have information about RAM disks (virtual disks).
My problem is that i need big disks (70 - 80 GB) and need real fast access.
Reg
JohanYes. A real peace of hardware. I.e. harddrives with RAM performance and functionallity. I would like to have 72 GB Data in RAM memory for fast access.

Disk Utility to format DVD-RAM disk
I have swapped out my Combo drive and installed an LG GSA-4163b so that I can burn, write to, DVD-RAM disks.
I have installed Patchburn which now allows me to burn CD's and all manner of DVD's but DVD-RAM disks will not mount.
DVD-RAM disk is recognized by Disk Utility but I cannot figure out how to make Disk Utility format the DVD-RAM disk. How do I do this.
Thanks,
DougHi Douglas,
should work pretty straight forward:
* Open Disk Utility
* Select the disc in the column on the left
* click Erase (select Quick Erase if you don't want to zero out the disk)
* Click Erase to start the process
