I want a subset of files on a usb to be less likely to corrupt or, have any contact with/ acess to, the rest of the files on the usb.
Q: is there any advantage in putting the subset on a separate partition within the USB drive?
i want the details of how many time and which type of usb stick used into the pc. Because i went to audit the cyber security.

I had a friend ask how he could do his electronic banking without a chance of any information being left on his computer once he is done.
I thought of a Ubuntu live CD but have seen the HD activity light flashing when using one. That leads me to believe that some kind of use is made of the HD and that makes a live CD questionable. He wants no information on the HD even in unassigned sectors.
Maybe, better yet would be a USB thumb drive that runs Ubuntu or another distribution that will not use the HD or even require that one be in the computer. A plus with a thumb drive would be that it would only be available on the computer when it is being used so it could contain passwords etc. Of course, it would have to be removed when not in use.
My friend gave me a flash drive with some important files on it that one day didn't work with his windows box. Upon plugging in the thumb drive, Windows gives a "you must format this disk before it can be used" message. I tried running a data recovery program (Easeus) on it but didn't have great results- only recovered some .wav files, a few .avi files and a .exe- none of which were very important, so I figure'd I'd try to mount it in Linux and possibly see the rest of the filesystem. The thumbdrive is a 2GB Lexar JD Firefly I plugged in the thumb drive and it is picked up by the system, but I can't access it. Here is the output of lsusb

The software: Ubuntu Server Edition 9.10.The wetware: A programmer doing his best (read: ignorant, shitty) as an ad-h.When I plug the USB thumb drive in, the install OS gives it a drive letter -- /dev/sdb -- and it pushes the original /dev/sdb down to /dev/sdc. The installation works without a hitch, and GRUB2 installs, dutifully pointing the root at /dev/sdc1 instead of /dev/sdb1.I let GRUB2 start normally ("drive not found"), holding the <shift> key to get to the "rescue>" prompt.From there, I issue "ls" to discover that GRUB can NOT see /dev/sdb, and I can tell that because what is showing up as (hd1) does NOT have three partitions as it should.GRUB2 sees a total of 16 drives, not 26, and one of the drives it sees is "fd0" (there is no floppy drive).Issuing commands like "set prefix=(hdx,y)" and "root=(hdx,y)" have no effect as, I think it's just pointing to the (reiserfs)content drives and this GRUB2 tells me "unknown filesystem".I did try them all in vain, hoping that maybe I'd find a kernel somewhere.I used the "rescue" mode of the Ubuntu installer (the USB thumb drive) to get to a root prompt.From there, I mounted /dev/sdc2 (the "shifted" /dev/sdb2) onto /mnt, I mounted /dev/sdc1 (the "shifted" /dev/sdb1) onto /mnt/boot,and then I chroot'ed to /mnt.I edited /boot/grub/grub.cfg, editing every instance of "root=(hd2,1)" to the appropriate UUID for the "real" /dev/sdb1. Then I issued update-grub2.It refused to work giving me an banal "no such partition" error or something like that.
We originally had this server functioning by putting / and /boot on the SS SanDisk, which caused no problems during installation because /dev/sda doesn't get shifted.We then figured it was a good idea to put our OS files on something with failover capability. And that started us down this crappy "shifting drive letter" path.Can I control which drive letter the USB thumb drive gets assigned during the install process?If I could make it be /dev/sdc then I wouldn't be facing this problem.An alternate solution would be to know the cryptic GRUB2 commands that I can issue from the command prompt post-install, pre-reboot.But I'm wondering if that will ultimately work at all considering that GRUB2 couldn't see /dev/sdb at all.
Saw a reference to putting the swap partition on a separate drive--just minutes after I was considering that approach. Can't find anything recent on the topic, so asking: Is there an advantage to having /swap on a separate HD from data on /home? My thought was that both disks could be active at once, perhaps speeding up a busy application.
View 1 Replies View Relatedone would have to exclude certain folders / directories but would the backup be possible if the system is up and running in its native "live" state ? Which directories could be excluded ? Does swap need to be turned off ? I would like to make incremental backups on a separate partition of the same hard drive. I will endeavour to backup the MBR/ Partition table using dd.

I have a new Giada cube with no hard drive, so my plan is to simply run a Linux/MythTV distro called MythDora from a Patriot 8GB USB stick (this Giada does not PXE boot). I am having trouble figuring out exactly how to make this work. Yesterday, although I have forgotten exactly how, I was able to put a MythDora Live image on the stick and boot up. I went through the initial setup, and then, when I was all done, I rebooted, and..it started all over again...as if I was doing it for the first time. So...What do I need to do to create a proper bootable USB stick?What ISO image should I use? The full DVD? Or the Live ISO? or the Network image?Do I need to partition the stick and load the O/S from one small partition, transferring the installation to another larger one?What utility should I use to create the bootable stick? unetbootin? or similar?Do I have to do anything special to make my O/S and configuration changes persistent on the USB stick?

View 5 Replies View RelatedThe following quote is the sad, sad story of a thumb drive with the partition table nuked, as told by a friend of mine:
Quote:
Data was recovered from an XP system by booting with a BartPC CD and copying onto a USB thumb drive. Nothing unusual.
System was rebooted into the XP install CD.
The first drive that was found was the 16gb thumb drive (AKA flash drive) and the person (re) installing XP didn't catch the fact that XP presented the 16gb thumb drive instead of the 160gb hard drive.
The drive partition function in XP deleted the partition table - on the thumb drive.
A freeware utility in Windows shows the data but can't recover the file names, so that everything is gobbledygook. Does anybody know of a utility or program under Linux that can help? I have a laptop running F 12 and can do the work if needed, but don't know what program to use.
I am looking for OpenVMS distribution on a thumb drive for a PC. I image it would be a Linux system that automagicly starts a VAX simulator then boots OpenVMS on that. Either it would run live off of the thumb drive or it would install to the system's hard drive.

I gave the USB drive a unique label with e2label. I added an entry for it in /etc/fstab. This works in the sense that if I run "mount -a", the drive will be mounted. However, it still isn't completely automatic. Am I missing something? What else do I need to do?
