Size required for El Capitan USB flash drive?

What is the size of the flash drive USB should have so that it contains a bootable installer from El Capitan?

Intend to upgrade my HD for one SSD and want to restart from a USB key.

The installer for OS X El Capitan takes approximately 4-5 GB of storage, so I suggest you use a 8 GB USB drive at least to create an OS X El Capitan bootable Installer.

    Hello

    You usually have an external USB CD/DVD drive to boot from the Windows XP disc or the Toshiba recovery disc.

    But there is a method that allows you to install Win XP using the 2 GB USB key.
    This is possible because the NB100 BIOS supports booting from USB key.

  • ScanDisk USB Flash Drive problem after upgrade to El Capitan

    After the upgrade to El Capitan, I can't access the vault secure on my USB Cruzer facet flash drive. I have Plug and display files as usual but when I try to open the safe, I get the message ' Scan Disk Secure Access V 2.0 requires San Disk USB Flash Drive. Please insert one. »

    The Flash Player has worked fine before the upgrade to El Capitan and I can still use the files outside of the secure vault but, basically, I cannot now access the secure vault. I'd appreciate any thoughts on how this can be resolved. I only am not an expert so please, keep it pretty simple.

    Sounds like a problem of compatibility with the Secure Access software and the OS X El Capitan of SanDisk.  Try download and install the latest version of Secure Access of SanDisk.

    It seems also be other users having the same problem, you may get better assistance with this through SanDisk.  Someone else said that upgrading to the latest version of Secure Access has solved the problem.

  • You are looking for a SIMPLE, EASY to USE, USB flash drive password protection

    Hello everyone,

    I scoured the Internet looking for a SIMPLE, EASY to USE, method of Word to PASS-PROTECT my flash drives TOGETHER.  I don't mean something that protects just individual files & folders (such as MS Word, Excel & can do).  Or I'm looking for a program that involves having to read page after page of instructions on how to ENCRYPT the drive.  ENCRYPTION is a topic that is really beyond my ability to understand.  I'm sorry.

    Programs like Truecrypt, Axcrypt, etc. are simply much too complicated for me to understand... a lot less!

    My question: are there flash drives available (size 8-16 GB preferably) who have a means of securing the disk with a password?

    The USB key remains in my USB port at ALL times!  I have no other computers here and live alone, so that no one else could access the flash player (or computer).  Otherwise, I would be willing to consider a VERY SIMPLE, EASY to UNDERSTAND AND USE application, either free or something that does not cost me dearly.  (I subsist on a limited monthly disability income).

    Thank you for your time and any recommendations!

    It seems that the solution for you would be to purchase a secure Flash drive.   Security is built-in and it asks for your password when you insert your disc into the computer.   Can't get much simpler than that.  They are a little more expensive, but you pay more for practical reasons.   See the following article:
    'USB Flash Drive Security '.
       <>http://en.Wikipedia.org/wiki/USB_flash_drive_security >
    To find one, just Google for "Secure USB flash drive", there are a lot of them out there.

    If you have a non-secure flash drive and do not want to replace, then your easiest option would be a program like Truecrypt which you already have reduced as being too complicated.  Don't let the word"encryption" you scared - it all comes down to "enter a password to access".»  Once established, however, it is almost as simple as only to enter a password so if you can find a computer or a local high school computer nerd literate member of the family who would volunteer to set up for you, then it wouldn't be that hard.

  • Slow data transfer for USB flash drives

    When I transfer a file to a USB flash drive, the transfer is very slow. I checked my USB host controllers and they work very well. There seems not to be of hardware problems. Here is the Dell gx270s, the two XP Professional SP3 running computers. I didn't find any solution on the support site for anyone. Controllers are Intel.

    Anyone who has ever had this problem and figured it out?

    3 are. what transfer speed you now?
     
    Check if the transfer rate is the same on another computer. Also, try using a player different flsah on this computer and compare the transfer rate. I would ask you to update the drivers for the chipset on the Dell site.

  • USB Flash drive problems

    I have a USB key that does not work. It's a drive 8 GB flash USB 3.0 which has been formatted and works on my Macbook Pro. The problem comes when I try to use it on a Windows device.

    When I format it under OSX Extended it appears under Windows but is empty.

    When I format it in FAT, under Windows it says that the device must be formatted first

    Either way, when I go to format the device on Windows it says that is only 200 MB space

    Any help would be appreciated.

    If you want to use a USB flash drive on the cross-platform (Win, Linux, OSX) computers you have the next chance:

    -MS-DOS (FAT) format:

    If you want to start the drive on a PC or use it with older versions of Windows, you may also need to set the partition to the Master Boot Record (MBR) for full compatibility Windows scheme:

    • Click the drive, and then select the tab "partition".
    • In the "Layout of the score" dropdown, select "1 Partition".
    • Click on 'Options' and choose "Master Boot Record" as the type of partition, then click 'OK' and 'apply '.

    Format discs very quickly, although the total time required will depend on the size of the drive.

    The file system resulting is compatible with all versions of Mac OS X, Windows 95, 98, Windows XP, Vista, 7, Windows 8, Windows 10, is one of the most widely recognized and usable file system formats. What makes FAT ideal of the file system to use for external hard drives or USB flash drives that are designed for use in environments with multiple operating systems.

    ATTENTION! The main drawback to the use of FAT32 is the file size limit, which limits the files on the drive to be 4 GB in size or less. If you need single files to be larger than 4 GB, use exFAT, even if you lose compatibility with older versions of OS X and Windows.

    -Format in NTFS and use a program like Paragon NTFS on your Mac ($ 15/20).

  • Laptop HP 17 p100: how the usb flash drive big that I have to create a system of 10 Windows Recovery?

    How the big usb flash drive do I need to create a system of 10 Windows Recovery?

    Yes

    Hello;

    Let me welcome you on the HP forums!

    There is really no way accurately guess in advance, with one of the reasons being that the options are available when you do this.  An option creates a recovery drive minimum with what is needed to repair the operating system.  Another option creates an image that is able to completely restore the operating system and its partition.  Thus, the size can vary from 4 GB to the size of the partition to the OS.

    Myself, I found as build-in recovery to be unreliable, especially those of Ms.  So instead, I use a third-party imaging/restoration solution known as Macrium Reflect.

    What I recommend is the following:
    (1) download and install Macrium reflect (MR)
    (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
    (3) use the option to create a CD or a USB startup key

    My experience is that SIR, when you use the option of Compression high, typically allows to compress the image file recorded at about 50% of the space USED in the OS partition.  This means that if you have a 40GB and 80GB OS partition is used, MR must only about 20 GB to store the image file.

    I use all the time and it usually takes less than 10 minutes to make the backup of the image and at the same time or less do a restore.  In addition, MR has the ability to add a recovery Boot Menu entry.  This then allows you to boot into Windows re, and then you can use it to do a restore - when you cannot start Windows!

    NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.

    Good luck

Is it possible to use the freespace (3 GB) to scratch partition? I created a FAT16 partition with the space (3 GB).

    The device must as well be greater than 5 GB, but also be a physical hard disk for scratch partition to be created. If on USB, there is not a scratch partition little matter the size of the USB unit.

    I would you ask my camcorder recorded videos, currently stored in Photos, iMovie, and the camcorder on a USB flash drive SD card so I can read in my car on the navigation screen. How can I upload videos to a USB key?

    Yes, you can store movies on your USB.  Probably the easiest way is to drag the movies.  USB drives which are formulated FAT 32, as most of them, are limited to 4 GB in size for any single file.  Would be good to try with a movie just to make sure that your USB will play your

  • Some USB flash drives REFUSE to work in this 40TL963B

    Hi all. I recently bought a new 40TL963B and so far I have found nothing wrong with her.

    Except that... when I listen to it all the Satellite channels, I noticed thay were very different from my FreeSat box. Duplicate the layers, randomly arrested... etc. It made me want to not use the built-in satellite feature.

    However, I found a program called ToshibaEdit which allowed me to manually change all the digital channels on the TV. Grand... I though. Until I met this problem-->

    Inorder to change the ads, you must copy the TV channels on a USB flash drive, you can edit them on your PC. Now, it took me AN HOUR to do, because of two flash readers I used, none of them worked... I kept getting a "Write Fail" error. WTF?

    The disks are formatted in FAT32, one is a 8 GB is 2 GB.

    Finally, I tried an external 2.5 "USB 120 GB hard drive. Even if the disc is defective... This WORKER. I expect flash drives to work, to be honest, but all of them... the external USB hard drive worked.

    In any case, I spent another hour sort channels, until I was ready to transfer the data back. And. Yes... the same problem. This time, I received an error "failed to read". Again, tried the external USB HDD... worked the first time.

    Now, this HARD drive is faulty, so he'll be thrown... so I'm going to need a flash player to do it again if something happens.

    And then... can ANYONE tell me why on Earth two appropriate, fully working almost brand new USB flash drives REFUSE to work in this TV, but a former, fairly well defective USB external drive MADE? In addition, the same flash drive that I tried to copy the data from digital channel with was also used for a backup of the Firmware... and it WORKED perfectly. It works also for use with the media player.

    While this TV has a hatred of Flash drives all of a sudden?
    Anyone can shed some light on this?

    In addition, very quickly, TV seems to lose its TV settings every time that I bring the TV out of Eve. I'm going to the TV Dynamic and adjust all the settings, but he returned to AutoView and all settings back to 0. Is it a fault or is there something I need to do to 'save' the settings per channel?

    Any help at all will be appreciated greatly.

    Hello

    > And then... can ANYONE tell me why on Earth two appropriate, fully working almost brand new USB flash drives REFUSE to work in this TV, but a former, fairly well defective USB external drive MADE?

    AFAIK the 40TL963B TV supports a common HS USB 2.0 interface and memory flash can be formatted in FAT16 or FAT32 file system. So there is no specific requirement for USB flash memory
