Fastest USB stick/key

I need a fast USB flash drive to offload rendering video. Would this be the fastest USB flash drive around: http://www.newegg.com/Product/Product.aspx?Item=N82E16820220253 ? That one says 200x but what does that translate to in MB? I'm guessing at least 30MB.
This is the same model number but notice it says 180x: http://www.amazon.com/Patriot-Xporter-Boost-High-Speed-Flash/dp/B000W1RV0Y/ref=s r13?ie=UTF8&s=electronics&qid=1239196687&sr=1-3 . Anyone know the true speed of this drive?
I use an iomega eGo now with USB. Its transfer is 480Mbits/s. It makes rendering video amazingly fast vs not using it. The main benefit is having an external drive to offload the rendering. I'm guessing the USB flash drive will do just as well since the flash drive should be faster than the eGo, although both will be limited by USB 2.0.

Die Marken (bis auf Sony) kenne ich nicht; ich wuerde sagen wenn is meist nur bei grossen Datenmengen passiert, dass es was mit der (geringen) Transferkapazitaet des USB zu tun hat. Ich wuerde mich nie auf USB verlassen wenn es sich um grosse Datenmengen dreht. USB ist langsam und der Port bekommt nur soundsoviel power; waehrend ein richtiger hard drive erstens seine eigene power hat (und sich deswegen nicht auf den computer port verlassen muss) und zweitens firewire was mindestens 2 - 4 mal so schnell ist.
Also wuerde ich sagen Sie sollten es mal mit etwas versuchen das seine eigene power (elektrischen Anschluss) hat und ausserdem firewire. USB sticks sind mehr fuer kleinere transfers gedacht.

Detect USB Stick insertion

I am trying to write a LabVIEW app that will be able to detect that a USB stick/key has been inserted into the computer. I know that I can get the names and serial numbers of all the drives that are currently mounted. However, I do not know how to check to see if one of them is a USB mass storage device, more specifically a USB stick as opposed to a USB-attached optical drive.
I could just check the size of the device and if it is under 4GB assume that it is a USB key. But if there is a more elegant way of doing it that I can be more sure of, I would like to do it.
Using LabVIEW 8.2.1
Kyle

Thank you. I think I am just going to go with the polling with the list directory VI every 100 ms or around that. Just compare the new list of drives to the old ones, if there is a new one I will take the action that I want.
I think the environment is controlled enough that we won't have issues with that. No one will be swapping drives out like mad (or at least they shouldn't be!).

[Guide] Windows 8.1 PRO RTM clean install on Yoga 13 from a USB Stick

Hello everyone,
I recently installed Windows 8.1 Pro RTM successfully so I thought it may be useful to share the steps here.
Disclaimer: Please proceed with caution. I'm not responsible for any gain, loss, or harm done to you, your device, or your data.
Link to picture
Pre-requisites:
1- Windows 8.1 RTM ISO image. (Available on the internet)
2- Windows 8 Pro license key. (Yes, It works with 8.1 also)
3- Windows 7 USB/DVD Download tool
4- Lenovo Yoga 13 Windows 8 Drivers
5- USB Stick or HDD with at least 4GB space. (Note: All data on disk will be erased)
Steps:
1- Important: Take a full backup of HDD.
2- Plugin the USB disk then open Windows 7 USB/DVD Download Tool.
3- Point to WIN8.1 ISO image path and wait for the wizard to finish.
4- After the wizard completes succefully, keep the USB stick plugged in and then restart the device in UEFI mode.
( + C -> Settings -> General -> Advanced -> Restart now -> Use a device -> USB UEFI Device).
5- It shall boot from the USB device and begin Windows setup wizard.
6- Specify the preferred language and enter the license key and choose advanced installation.
7- In disk allocation wizard, delete partitions with the following labels: LENOVO, WINRE_DRV, SYSTEM_DRV
(Warning: Don't erase partition labeled PBR_DRV as this will erase the Lenovo recovery drive).
8- Select the resulted unallocated space (should be around 106 GB) and click next.
9- Now wait until Windows completes installation.
10- Customize Windows, install Windows drivers downloaded earlier and restore your backup.
11- Voila, shall you encounter any problems don't hesitate to ask me.

Solved!
Go to Solution.

Sorry, forgot to mention that in order to boot from UEFI the flash drive must be formatted as FAT32. Windows USB and DVD tool supports only NTFS, So after creating the bootable image, copy all the files from the flash drive to the HDD then format the flash drive as FAT32 then copy the files back from the HDD to the flash drive. The flash drive will still be bootable.

Apple/Mac/MBP install from USB stick.

Hi,
I am having trouble starting the installation process from a USB stick on a MBP (8,1). I followed the instructions at
https://wiki.archlinux.org/index.php/Pu … n_Mac_OS_X
to prepare the USB stick, but am unable to convince the MBP to boot from it. I have tried both using the "Startup Disk" pane of Mac OS X's System Preferences, as well as restarting and holding down the "option" key; I just get the option to boot from the internal hard drive.
Any help would be much appreciated. Thanks!

katelman wrote:https://wiki.archlinux.org/index.php/Pu … n_Mac_OS_X
If I'm not mistaken, the USB drive has to be formatted a certain way for a Mac to boot it.
I couldn't get it to work either, but I'm trying (right now, even), to see of another method will work. I'll get back to you if I have anything noteworthy.
EDIT: Yeah, I'm getting nothing. If anyone else has input on this, I'll be happy to listen.

Macbook Air Won't Boot from USB Stick

I'm having an issue all of the sudden with trying to restore Lion on my Air. I've been messing around with partitions and setting up triple boot (linx,windows,mac). I had it working but wanted to remove it all and try again. Ultimately if I can just fix the partitions that's all I'd need to do, but I couldn't figure out how to do that so I figured if I just re-installed Lion completey it would fix it.
The current status of my partitions looks like this:
/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *121.3 GB   disk0
   1:                  Apple_HFS Macintosh HD            90.4 GB    disk0s1
   2:                        EFI                         209.7 MB   disk0s2
   3:                  Apple_HFS TMP                     30.3 GB    disk0s3
I can't seem to merge disk0s1 and disk0s3 because the EFI partition is in the middle and can't be changed.
When I boot my air, and try to boot from a USB stick that has the Lion installer on it, I get a picture of a circle with a line through it. Kinda like a no smoking sign except no cigarette.
So I have a couple questions:
-Is there a way to fix the partitions?
-Did something I do to the partitions effect me being able to boot from another device?
-Is there anyway to do target disk mode with a macbook air? (if so can I do that erase the drive and install Lion on it?)
Thanks!

Restart your Mac while holding Command+Option+R until you see a spinning globe appear along with a message about the recovery mode. If you have a Mac with a wireless keyboard you should wait a few seconds before pressing and holding the keys after you first see the light grey boot screen.
This will force your Mac to launch Internet Recovery. You’ll know that you are in Internet Recovery when you see a spinning globe and a meter running underneath it.
Lion Internet Recovery only works on WPA and WPA2 networks.

?move app-created files from ipod touch to standard usb stick via pc

Hi,
I would be grateful if anyone can help with this question:
How do I
backup app-content-files-I-created to a standard usb stick
which may involve locating where they are on my pc
remove app-content-files-I-created from iTunes and from my pc
(the app in question is the adorable DM1 by Fingerlabs)

App data is included in the backup that iTunes. The backup is located here. Yu can copy to USB stick and then delete the file from your computer.
Where iTunes backups are stored on your computer
The folder where your backup data are stored varies depending on the computer's operating system. Make sure the backup folder is included in your periodic data-backup routine.
iTunes places the backup files in the following places:
Mac:~/Library/Application Support/MobileSync/Backup/
Windows XP:\Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Note: To quickly access the Application Data folder, click Start, and choose Run. Type %appdata% and click OK.

Note: To quickly access the AppData folder, click Start. In the search bar, type %appdata% and press theReturn key.

No usb sticks show up on my mackbook pro

Hi,
I have a big dilema, any usb stick that i insert does not show on my macbook pro. Card readers work, Usb Drives (backup drives) work but USB Sticks don't work at all. I have tried about 3 or 4 different ones. Some error happened about a week a go when I was transferring some .f4v files to some USB Sticks, it worked on one but when i transferred to another it gave me some error and it all stopped working since. Also, now when i put a USB Stick in, the whole desktop freezes.
I have the latest software installed.
Can someone offer some support?
Thanks

SMC reset for MBP:
1. Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
2. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
3. Release all the keys and the power button at the same time.
4. Press the power button to turn on the computer.

USB security key not working with Mac

Hello! I have a windows compatible medical program that I am trying to run on parallels on my mac. The program uses a USB security key to work. Mac nor parallels (i have win XP running on it) is detecting my security key. The key is recognized on a different windows XP PC though. any thought??? greatly appreciated!

Hi OGELTHORPE,
My USB stick was originally formatted as MS-DOS (FAT) as default and out of the box. As I understand this is the same as FAT32 on Win (?)
MS-DOS (FAT) configuration was however what led to all of my problems stated above.
That is why I'm confused.
Before writing to the discussion board, I reconfigured the stick to ExFat, based on some similar research, but an article discussion advised the ExFat not to be a stable nor reliable configuration. I do not know why this issue was mentioned, but several users logged this as an issue of the ExFat.
If you have a USB stick meant for Mac use only, not cross-platform, do you alter configuration from MS-DOS (FAT)?
(Primary use is for Mac backup only, I'm willing to give up the cross-platform requirement)
I also don't understand why my Mac didn't detect a second USB stick, prior used on a different Mac.
Thanks!

I don't understand how to put the core files on usb stick

I read the instructions here http://wiki.archlinux.org/index.php/Ins … _USB_stick but I am not sure how to do this I tried this way ( using cmd prompt on winxp x64) dd if=C:\Documents and Settings\Administrator\My Documents\Torrents\archlinux-2008.06-core-x86_64.img=/dev/sd[F]
but I get an error saying that dd is an unrecognized command, I have also downloaded Flashnul but I am not sure how to use it if I type in anything I cannot execute it because as soon as I push the enter key Flashnul quits. so could someone explian to me how to do this please

jo3 wrote:

I have not used flashnul in a while so IIRC first plug in your usb stick and type "flashnul -p" at a command prompt to get a list of devices. Then type "flashnul flash_device_number -L archlinux-2008.06-core-x86_64.img" to copy the img to the device.
HTH
-jo3
hank you for your reply.
Well Iguess flashnul isn't working properly because when I type in "flashnul -p" it just quits.
I installed Cygwin and have tried to install it that way but I was getting errors saying no such file or dir.
Well it ended up being that my usb stick was "f: I kept trying dd if=archlinux-2008.06-core-x86_64.img of=\\.\f:Kingston"and not "f: I kept trying dd if=archlinux-2008.06-core-x86_64.img of=\\.\f"
I am thinking that the The Cygwin Way
Make sure your cygwin installation contains the dd package.
Place your image file in your home directory, in my case it is:
C:\cygwin\home\John\
Run cygwin as administrator (required for cygwin to access hardware). To write to your USB drive use the following command:
dd if=image.img of=\\.\[x]:
where image.img is the path to the img file within the cygwin directory and \\.\[x]: is your USB device where x is the windows designated letter, in my case "\\.\d:".
Note: This will irrevocably delete all files on your USB stick, so make sure you don't have any important files on the stick before doing this.
should say that for noobs like me

USB sticks get disconnected after a few seconds

Hi guys!
I got a problem with 2 of my 4 USB-Ports on my new iMac 21" (Mai 2012). To the first 2 USB-ports I hooked up my printer and my TimeMachine-HDD. The other ones I use for pluggin' in USB-datasticks . For some time now either one of these problems occur:
The USB-Stick doesn't show up at all - or: it connects for a few seconds, but then the warning appears which says I hadn't remove a disk safely. Apparently this only happens with usb-datasticks. My external harddrives work fine on them.
As long as they appear for some seconds they are also regocnized by the Disk-Utility program. Once I even managed to run the Volume-control; said the stick was fine...
This is what I already tried:
- made sure that the sticks plugg in right (they do)
- formatted the sticks (formatted to Mac OS Journaled extended)
- rebooting the imac (sometimes helps for a few minutes)
- I reset the SMC by shutting down, removing the powerplug for sometime and then booting up again (didn't change a thing)
- I tried to connect other external devices to these USB-ports (USB-keyboard) - most of them work fine!!!
- Thought that maybe it was a problem with MacFuse/NTFS-3G; but I have the same config on my macbook. There the problem doesn't show.
I really do not know what to do next! I rely on the transfer of data per USB-Sticks enormously.
Do you guys have any idea?
Any help would be deeply appreciated.

How to recover notebook with Recovery DVD's instead of USB-stick?

I've ordered a Recovery kit from hp.com for my Compaq Mini 110c.
Apperantly HP sends DVD's to recover notebooks... I don't know if they know it, but there is no DVD-player in a notebook.
To order a recovery kit, I had to fill in a sheet with my model number and serial number. So they should know what kind of system I have. But OK, let's get to the point.
First of all, my keyboard doesn't work, my trackpad only works when I didn't touch my keyboard after reboot. If I press any key the trackpad doesn't work anymore and I have to connect my USB mouse. And I cannot connect to my wireless network.
I've had a stupid virus on this notebook and I think that's why its acting strange.
Before ordering the recovery kit, I tried formatting my system with a default Windows XP disk (after copying it to a bootable USB stick). I managed to get to the setup menu in XP, but apperantly the SATA-disks in my notebook are not recognized by the WinXP setup.
I don't have a legal Windows Vista or higher version available.
So I've ordered the recovery kit from HP. When I try to make a bootable HDD with the recovery DVD's, I get a warning that some file on the DVD was not found.
I'm a bit out of ideas to recover my notebook.
Any help or remarks would be great...

Hi Thom,
There are Two options available.
1. You can order a replacement set of Recovery Discs using the link below - these will reinstall the operating system, all required drivers and nearly all of the original software ( the exception often being trials of MS Office ).

[SOLVED] Installation on UEFI from usb stick

Greetings,
I'm trying to figure out this uefi thing and install arch on my laptop.
I swear, I've been trying so many times now that I have a headache. My girlfriend too because of all my ranting.
I downloaded the latest arch iso and "burned" it to a usb stick (my laptop lack a cdrom).
I booted with the first option and went through the whole installation progress to the grub installing part MANY times before realizing I was doing it all wrong and I had to start from a UEFI shell.
Now I started from the UEFI shell and I just have no idea what I'm doing, the beginner guide doesn't seem to explain this.
I should probably wait until my headache pass and I'm fresh and ready to start over but I'm one stubborn guyif there is one and I had enough of failing, I want it to work.
What do I do from the UEFI shell?
Do I have to reinstall everything from scratch, partitioning and all or I can just get back to the part where I have to install grub? What do I do?
Thanks in advance and sorry if I'm asking stupid questions or something but, honestly, I failed so many times that my frustration is seriously high.

Hi,
this is basically what I followed and it worked for me:
make an archlinux uefi usb stick (it's a bit different than a normal one). Use a live ubuntu cd or something, so you don't have to use windows:
#format your usb key on /dev/sdXY to fat32 (replace XY with the right device, in the following code too)
sudo su
wget http://mirror.us.leaseweb.net/archlinux/iso/2013.08.01/archlinux-2013.08.01-dual.iso
mkdir -p /mnt/{usb,iso}
mount -o loop archlinux-2013.08.01-dual.iso /mnt/iso
awk 'BEGIN {FS="="} /archisolabel/ {print $3}' /mnt/iso/loader/entries/archiso-x86_64.conf | xargs mkfs.vfat -F32 /dev/sdXY -n
mount /dev/sdXY /mnt/usb
cp -a /mnt/iso/* /mnt/usb
sync
umount /mnt/{usb,iso}
full instructions here: https://wiki.archlinux.org/index.php/Un … B_from_ISO
now you have the instalation usb ready.
When I did this, i could still go to choose my boot device and i had a normal usb key boot option and an uefi shell usb key option, see if you have something like that to be sure you have the uefi boot. you should see an uefi shell and it should boot automatically as a normal archlinux live usb. if it doesn not (happend to me before) run ./start.sh or something like that (it should say in the uefi shell what to run). If that doesn not work, then the uefi usb key didn't work.
okay if you've successfully booted the uefi usb you have to format your drive so it has the uefi boot partition mounted inside the grup folder, so there has to be a ef00 partition on the begining
This is my actuall install script, it will wipe your drive, make 5 partitions (uefi boot, boot, swap, root, home) and then mount them, install arch and then chroot into that
modprobe efivars
#configure this as you wish
SWAPSIZE=4G
ROOTSIZE=50G
DRIVE=sda
#these two lines are horrible, you could manually use gdist and format the drive as you wish, as this will just wipe it clean and make the partion table that I have.
dd if=/dev/zero of=/dev/$DRIVE bs=1M count=1k
echo "2\no\ny\nn\n\n\n+100M\nef00\nn\n\n\n+100M\n\nn\n\n\n+${SWAPSIZE}\n8200\nn\n\n\n+${ROOTSIZE}\n\nn\n\n\n\n\np\nw\ny\n" | gdisk /dev/$DRIVE
mkfs.vfat -F 32 /dev/${DRIVE}1
mkfs.ext2 -L boot /dev/${DRIVE}2
mkswap -L swap /dev/${DRIVE}3
mkfs.ext4 -L root /dev/${DRIVE}4
mkfs.ext4 -L home /dev/${DRIVE}5
swapon /dev/${DRIVE}3
mount /dev/${DRIVE}4 /mnt
mkdir /mnt/home
mount /dev/${DRIVE}5 /mnt/home
mkdir /mnt/boot
mount /dev/${DRIVE}2 /mnt/boot
#this is the magic uefi part for grub
mkdir /mnt/boot/efi
mount /dev/${DRIVE}1 /mnt/boot/efi
pacstrap /mnt base base-devel zsh
genfstab -U -p /mnt >> /mnt/etc/fstab
arch-chroot /mnt
After doing that, you have can install the system as you wish and for the grub I do this:
I had problems a few times if i copy pasted all these lines at once, so now i copy paste them one at a time, (I know it should not make a difference but still, sometimes it didn't work)
# i do this in chmod too, though I'm not sure if it's really necessary
modprobe efivars
mkinitcpio -p linux
echo "installing efi grup thingy"
pacman -S --noconfirm efibootmgr grub-efi-x86_64
grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=arch_grub --recheck --debug
mkdir -p /boot/grub/locale
cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo
grub-mkconfig -o /boot/grub/grub.cfg
and this is all i have in my install script file and uefi works fine. I hope you'll get it running soon

1)Problems with Fusiondrive 2) Can't start from USB-Stick to repair

I have a big problem witn my self created fusion drive on my macbook pro. For weeks it worked fine and fast. But since the last week more and more errors ocured, such like stopping com.apple.medialibrary service etc. The system ran hot and hanged sometimes or shut down suddenly..
Now, it won't start anymore.
Following message appears after turning on:
panic(cpu 0 caller 0xffffff7f93075b65): *This LVG was created before the fix for <rdar ://11023142>,you must recreate your LVGs"@/SourceCache/CoreStorage-380/core/btree/btree_impl .h:55
Debugger called: <panic>
Backtrace (CPU 0), Frame : Return Adress
....followed by somelines of hex-adresses and further error mesages corresponding to the LVG-Problem...
I tried to start from my mavericks-usb-Stick, which works on my second Macbook (nearly the same settimg) fine and without problems. I pressed the "alt"-key while system start and could choose the stick as startup medium.
But after a few seconds the same error messages appear... The system won't start.
So I can't reformat and create a new Fusion drive. I have erased the NVRAM, which solved the problem, that the startup chime was missing...
I tried also to start with cmd+R, but the errors stayed the same...
Please is there anyone who can give me a hint. I need my macbook and I have only today a little time to fix it...
Thank
Mike

Thank you for your answer. I have put me internal DVD in an external case to make place for the hard disk (the ssd is at the old place of the hard disc).
I can't choose the externalDVD to start when I press "alt"-key...
Any other idea?

Cryptsetup luks boot mkinitcpio usb stick encrypted

Hi,
I am using cryptsetup and LUKS for encrypting my home partition.
Till now i've used ASK for PASSWORD in /etc/crypttab
But i wanted to use a usb stick for storing a key.
Reading https://wiki.archlinux.org/index.php/LUKS
I successfully have created i key, i added it with luksAddkey and everything seems to be ok.
I have a vfat usb stick that i have copied to the keyfile.
I did my tests, and its works fine.
So, i tweaked my /boot/grub/menu with this:
kernel /boot/vmlinuz26 root=/dev/sda3 ro cryptkey=/dev/disk/by-uuid/D74E-9973:vfat:keyfile cryptdevice=/dev/sda4:encrypted
I have edit /etc/mkinitcpio.conf to add some kernel modules and encrypt hook
and created a new kernel image for safety (i want to have a failsafe kernel image too);
base udev autodetect pata scsi sata encrypt filesystems
the problem is that: poll_device "${ckdev}" is failed (line 24 in encrypt hook) and i am reading
"Keyfile could not be opened. Reverting to passphrase"
I've hacked a little the encrypt hook to debug why poll_device is failing, but i cant figured it out.
The rootdelay is 10sec already.
It seems that my usb device cant be recognized from udev hook (Before encrypt) and my kernel image dont seem to find the external usb stick.
Any help would be appreciated it.
PS: Sorry for my bad english

Yes, mkinitcpio will be integrated in the next version of larch, which is gradually taking on form - at present I am reworking the hard disk installer.
As phrakture is working on a live CD based standard arch installer, I am hoping it will be possible to share much of the code.
It would of course be possible to integrate mkinitcpio into the current larch version, but it would require a bit of cleverness and probably some changes outside of the initramfs bit to cope with the limitations of the klibc environment (or else continued inclusion of busybox in the initramfs). Anyway, I think it would be better to wait for larch version 2, which has been designed with all this in mind. The approach used in version 1 works fine, it is just not quite the same as the new standard Arch boot sequence (and there need to be adaptations for live CD booting anyway).
