Windows 7: Memory fills up to 90% and never goes down with Truecrypt - on or off!

Memory fills up to 90% and never goes down with Truecrypt - on or off!


first post!

I have been using truecrypt on my win7 ultimate x64 with 4gb RAM, usually I have 15%-30% memory used when idling or with firefox open.

When I mount a truecrypt volume, the memory hits 90% and everything slows down. Even shutting down truecrypt fully doesn't help.. a full reboot is the only way.

Checking memory usage in task manager shows no application using much memory, just that 90% is being used..

It's a strange problem.. does anyone have any ideas?

Is volume in a "container" (or TrueCrypt file) on an otherwise normal NTFS drive? Is drive an external - USB, whatever? Is the TrueCrypt volume very large - say larger than 1 TB and nearly full?

It is either a too large volume with too many files or due to the external drive driver interacting with TrueCrypt. An internal drive with a 1TB volume and 2/3 full of files causes no problem here. An external USB 3.0 drive with a 2.5 TB volume and 3/4 full gets the same results you are getting, especially when copying or backing up for long periods.

All memory used when copying files from Truecrypt container
I'm in the process of moving data from a WD 3TB USB drive to a larger WD 5TB USB drive, so there is a LOT of data to move around. While this is in all probability a Truecrypt (TC) issue, it doesn't hurt to ask anyway! I have a quad core i7 pc with Win 7 Home and 16GB RAM, which is the limit for...

Cached fills up physical memory
From the moment I turn on my computer the cached memory slowly goes higher and higher until it gets to 90%+ physical memory usage and I have to restart. I'm really not good with computers so I have no idea what's going on.

Physical memory suddenly fills up, computer slows down
My HP desktop suddely slowed down for no reason -- to a "snail's pace" -- and I opened windows task manager and saw that the memory was 99% full. Restarting solves it for a few minutes, then it happens again. I've run Anti-virus (Avira says I have "multiple hidden files") -- and I need another...

Cache memory fills up RAM so I can't play performance heavy games
Hello, I have a really powerful gaming rig with Intel Core i7 2.8 GHz, Crucial C300 64GB SSD and 8 gigs of RAM which most would think is more than enough to run even the most performance demanding of games. I was playing COD: Blackops the other day and Windows told me it had to close some...
