Force erase/Format an external hard drive

I spent $ 140 on an external hard drive Seagate Backup Plus. As you can imagine, the instructions are crap. None of the software that are supposed to be installed on my external hard drive is there, and I am not given the choice of formatting a Mac.

So I thought I could just open disk utility, erase the hard drive, then format for Mac.

But when I click on the delete button, I get the message "failed the erase process.

Is there a way I can replace the error messages and force to erase an external hard drive?

Thank you.

Have you tried the tab partition in disk utility? This will erase the disc and give you the ability to format in Mac OS extended (journaled).

  • External hard drive does not work. Is there another way I could solve the problem without formatting the external hard drive?

    My external hard drive works. I tried to plug and when I tried to open it, it says to format the drive until I could use it. Everything works well as when I plugged the USB icon shown on the screen. When I check the disk management, it showed that the partition of the drive is there.

    I tried to change the drive letters, but still having the same problem. I also tried to run the disk check on the command prompt and the properties of the drive, but it still can not because there is error popping up saying that the disk check cannot be performed because Windows cannot access the disk.

    Is there another way I could solve the problem without formatting the external hard drive?

    I tried the first step in troubleshooting the hard drive, but it gives a
    error in saying that "hardware changes might not have been detected.

    So I tried the second method, and when I click on the "Check now" button his
    gives an error saying that "the disk check cannot be performed because .
    Windows can not access the disk".".

    So is there any other way or option?

    Thank you

  • Formatting an external hard drive to FAT32 using vista

    Hello

    I own an Xbox 360 and a Windows Vista-based computer.  I wanted to store music and movies on an external hard drive and connect it to my Xbox 360 so I can make use for more then just a game.  I first tried this using a 2 GB USB key and it worked better then I could have hoped.  However, given that 2 GB does not go very far, I went out and bought a FreeAgent 1.5 TB drive external hard.  I can use it in Vista and works very well, but it does not recognize the Xbox 360.  I read in a forum that the 360 requires the external hard drive to FAT32, but Vista cannot format the disc in all except exFAT and NTFS.  How can I get the external drive in a format that can recognize the Xbox?

    Thanks in advance.

    Hello, Durandal95

    Please use the Forum for answers.

    You can format a drive using the FAT, FAT32, exFAT and NTFS filesystems using the format command-line tool.

    WARNING: Formatting your drive will completely erase it, exercise caution when you use the format features.

    To do this, go to start, all programs, accessories, click with the right button on command prompt and choose Run as administrator. In the command prompt window, type the following command and press ENTER: format X: / FS: FAT32 / q
    Note: Replace X: the good reader.

    You can find help on the XBOX on both, the help and the community pages:

  • Question: How can I format an external hard drive

    I am trying to use an external hard drive with Time Machine.  He tells me that my external must be formatted in a format "journaled". I can't find any way to do it and the Mac is do not do it either. Can someone tell me how to proceed so that Time Machine works to put in shape?

    If Time Machine is not reformat the disk itself, choose Utilities in the Finder Go menu, open disk utility, select the drive in the sidebar and delete it.

  • Impossible to format an external hard drive?

    So, I am trying to format a 1 TB WD My Passport external hard drive but get the error messages.  I recently completely wiped out this player because he was running extremely slow and when I try to create a simple format through the disk management I get an error message "request cannot be performed because of an i/o error".  He also sees the drive, in disk management, but there is no associated letter and he said that all of the disk is not affected (931 GB).  How do I get this problem?

    In cases where the Disk Manager does not work, I use a 3rd party application EaseUS Partition Master Home Edition (freeware @ easeus.com). It allows to create a partition in the unallocated space, and then name it and assign it a letter then put it. Then, Windows will recognize the newly formatted disk.

    I don't know why Windows won't do, but I had this happens on two external drives, and it works.

  • Format an external hard drive (1 TB) FAT32 in NTFS file system

    Please I need answers to my doubts.

    In Windows Explorer, right-click on the drive and select Format. Choose NTFS as method in shape.

    You will have 930MB after formatting. The rule is that you have 7% less space than the nominal capacity, which allows the difference between the ability of manufacturers of discs (1 GB = 10 ^ 6) and the ability of Windows (1 GB = 2 ^ 10) and space unusable, drawn upward by the method in shape.
  • How to format an external hard drive

    I have a Seagate 0.5 to drive and I want to format using an iMac. It was previously connected to a PC and is probably implemented in FAT16 or FAT32.  When I select a folder on the disc, working in "Finder", I find that I can not remove it so I have no way to make space.

  • Formatting an external hard drive after use on NSLU2

    I have a Western Digital 1 TB my book I am recovering for use on another windows system.

    When I plug it into a Windows 7 system, it is unable to find the driver HID - but I think this might get fixed by downloading the right driver.  Seems to work without the driver HID anyway, so I continue.

    The drive is not visible in Windows Explorer, so I open Manage and go to storage-> disk management.  A window pops up which informed me that "you must initialize a disk before logical disk manager can access it."  I select the disc and use the MBR partition style, and then click OK.  A new pop-up appears with the title "Virtual Disk Manager" and the message 'the system cannot find the file specified.'.

    Right, I'll fix that.  Time to get out the heavy artillery.  I run DISKPART, the command line process.  "LIST DISK" shows me what number of disk I need.  'SELECT DISK 1' makes it active.  'CLEAN' it erases.  'CREATE PARTITION PRIMARY' will activate I... Oh. "DiskPart has encountered an error: the system cannot find the file specified. '. Check the log of the events system for more information. ».  Not good.

    Any ideas?  The drive was used as backup - disc 2 of a set of two motor external - drive and were reported although the last backup.  I did a lot of research for this and found nothing so far, no idea why the NSLU2 product disk unformattable?

    I managed to find a solution to myself.  It was an oversight on my part.

    Once I have had reconnected the drive for the system, I started Manage-> Storage-> management of the disks, and then deleted the current partition on the WD My Book.  Then I could add a partition and reformat to NTFS.

    I don't understand - if you force quit smoking, launches the application, or you can not force it quit?

  • How can I change the permission of my external hard drive from tours and write "without formatting?

    My Toshiba external hard disk format was automatically replaced Windows NTFS after I had plugged on a Windows PC. Therefore, the permissions of the drive changed to 'read only' to "read and write" after that I used on my Mac. It happened once before and I remember the engineer on duty in an apple authorized service center had solved the problem without format the external hard drive. This is not an option for me now as well, but all the solutions, I looked to say online that the formatting of the disc is the first step. Help, please!

    Install software such as Paragon NTFS on the Mac.
