I have an external usb hard drive (WD Passport 1 TB) formatted (encrypted) for my Mac. Even before I encrypted it, I could only read but not write from my linux pc. After encryption not even that.
I need a new external HD for my linux pc, the one I am currently using is getting too old and is FAT32 formatted (from when I was still using Windows).
Questions:
If I want to encrypt an external usb HD which filesystem should I use?
Will I be able to use it on a multiboot linux (no windows) pc when encrypted? (Will I just be asked for password before use?)
Are there brands that are recommended or that I should avoid?

thanx

TrueCrypt is best for external drives as it is available for Linux, MacOS and Windows. Using an OS-specific encryption system may cause you problems at a later date.

Some good out of the box thinking.

What would be the best filesystem to use? Especially for use with Mac OS X and linux and being able to write files larger than 4 GB?

Anyone experience with UFD as filesystem for external USB hard disks?

UFD? I'm not familiar with that one, but I'd stick with TrueCrypt as it provides everything you need in one cross-platform box.

Yes, truecrypt to encrypt, but which filesystem that is read- and writeable by linux, mac osx and windows? NTFS, no because I hardly use windows. FAT32, no because limit of 4 GB filesize, ...
Someone told me to try UDF, the universal disk format, I wondered if anyone here has experience with it.

It's been a while since I used Truecrypt and I thought it included the filesystem, but it doesn't. Hardly is not te same as never, so I would still use NTFS for maximum portability, although exFAT is looking more interesting these days.
