DiskWarrior frozen — "lack of memory"

holdmusic · Aug 31, 2012

Sorry if this is in the wrong forum board.

I have a macbook pro with SL. I'm trying to run DiskWarrior from a thumb drive that has SL installed on it. Whenever I start the "rebuild directory" cycle, everything goes fine and dandy until step 5. The window then says "Speed reduced by lack of memory". Soon after that, the cursor freezes. I left it alone for 15 hours, but nothing changed and I had to do a force restart.

I booted up again from the thumb drive, opened Activity Monitor, and checked on the memory. It says I've got about 570 mb of free RAM, so I don't understand why DiskWarrior says it doesn't have enough memory.

I'd very much appreciate any help you can offer!

Might be due to page outs. How much space left on the thumb drive?

The drive has 3.62 gig capacity, and it has 440.8 meg available.

I think the 440 MB on the boot drive is all that Disk Warrior has to use as temporary file storage space - it uses temp space for the re-created directory for the larger disk. (I think the page-outs described by cradom fit into this)

So are you saying that I need to free up space on the thumb drive? It's strange, because my dad uses the same thumb drive to run DW on his computer, and it works fine. Though it is a newer macbook pro.

Disk Warriors cache is dependent on how much stuff you have on your drive. the more stuff, the more space it needs for directory information.
Also, if the OS needs more memory for a task, it will write portions of memory in use by other things to disk so it can use that memory.
With the combination of the two, there might not be enough space on the flash drive for it to do it's thing.
All that being said, it could be something totally different causing the problem. Anyone else want to chime in?

Do you not have DiskWarrior on a DVD? The best option is to boot from that and run the program.
