comment Is there a tool like dm-crypt/luks using RSA encryption?
Would it be possible to save the encrypted symmetric key first?

comment Is there a tool like dm-crypt/luks using RSA encryption?
Is your concern that it should be possible to restore parts of the data if the system is interrupted, but only with the private key? If not, encrypting unmounted volume files or archives with e.g. GnuPG seems like an easier solution. I wouldn't mind a tool that locks on power loss while allowing appending data over a long-ish time frame though, so +1 for the question. (Asymmetric cryptography is usually used to protect an attached random symmetric key, since it's apparently very inefficient (cycles/key strength) compared to the latter. A sym. key in memory while it's mounted would work here.)

comment Truecrypt using up all the disk space during decryption
You should be fine just zeroing a bit... but then it could expand again when that space is overwritten. The reason you need to zero it in the first place is that it's currently filled with random data that is close to impossible to compress. (I also assume compacting will cut out only parts that are zeroed.)

comment Truecrypt using up all the disk space during decryption
According to the SDelete page it will run on the guest, whether compacting the volume file from the host will work depends on the Raid5 checksum for (0, 0). If it's 0 there's no problem but I couldn't verify this with a quick search. (I would assume it is though.) Still, I recommend making a backup before modifying anything on that scale.

I'm pretty sure you can just shrink it with Disk Management once you've made enough free space. Any files on the spare drive should be relocated automatically.

comment How to install 2 encrypted instances of Linux Mint on the same SSD, both with different encryption passwords?
If there's a system that allows secret volumes à la TrueCrypt, you could set up some boot forwarding volume that way, but updating it from the wrong system would wreck the other one... Otherwise I think you can set it up to give you the choice first and then ask for a password, but I know no existing solutions that choose automatically by password alone.

comment Hide files without attributes
I worked around the problem for now by symlinking Dexpot's desktop directory to a subfolder in a synchronized directory. It should be possible to create a general solution for making files unlisted in specific programs with a file system minifilter, but unfortunately I don't know enough C to implement that.

comment Hide files without attributes
The links you posted only deal with encrypting or renaming a file. If you read the whole question text you will see that I probably can't move the file. I'm really just asking for a method to hide the file in Windows Explorer that does exactly that. I know this question is a bit narrow, if you have a workaround that solves my problem but doesn't answer the question feel free to post it as comment.

The addition is even farther beside the point though...

comment Hide files without attributes
I don't want to hide all hidden files. The file is already marked as hidden and I can't change the attributes to include system as explained above. This question is about finding a different way.

Ok, the drive seems to be failing. Thanks for your help.

comment Sporadic registry file failure on startup
I'm doing a "short" self-test with ESWin right now, but the progress bar has stopped at 80% two hours ago (it's a 1TB drive). The SMART data is completely fine though. The read error rate is slightly elevated at 0x1AF, but still far away from the 50% warning. (If I'm reading this right it's less than a tenth of a percent.)

comment Sporadic registry file failure on startup
@Brian It wasn't overclocked - I even looked up the stepping on the maker's site. I'm rather sure it's a problem with the memory addresses: The screen corruption I got a few times moved pixels in an irregular pattern to the right while keeping the colors. (I made a screenshot when it happened.) This seems to be unrelated though, as the error is always the same and occurs when the computer is still cold...

Testing... I already though I'd have to write a DOS floppy to use Samsung's disk tools. Then I found their S.M.A.R.T. utility in the external drives section wich leads to a 404 when accessed from the internal drives page...
