• External hard drive USB on Time Capsule

  Hello

  I have an external USB hard disk and plug it into the USB port of my Airport Time Capsule makes it accessible wireless (if on the sidebar of the window under the section 'sharing' I click on the Time Capsule to enter airport name next to his record 'data', I also have a folder with the name of my USB HD and I can access).

  Now the problem. I have a USB external hard drive, I can access normally connect my iMac or iBook portUSB one, but, if connected to the time Capsule... nothing happens.

  So there must be a difference in the two external hard drive. What a difference creates the problem, why and what I can do is my question.

  Can someone help me?

  So far, here is what I found to be the similarities and differences:

  The two serial ATA, 2 to, partition GUID mapped external USB hard drive.

  In disk utility, one that is visible on the Time Capsule is displayed as 'external HARD disk support' physical disk with OS X extended physical volume. One who isn't appears as physical disk 'external media' with logic extended OS X volume.

  Hi Ranmaboy,

  I understand you have two external hard drives USB that you want to connect to your airport Time Capsule via USB, but one who is not recognized by the Capsule from the airport. Given that this player connects to your iMac without problem, I would recommend that you backup all data stored on the disk, and then follow the steps here to re - format the drive using disk utility:

  Backup disks, you can use with Time Machine - Apple Support

  Format a drive connected to an AirPort Extreme 802.11ac or Time Capsule

  If you are using an AirPort Extreme 802.11ac or Time Capsule, you can connect an external drive to the USB port on these devices for use with Time Machine. Follow these steps to reformat the hard disk in the first place, it is ready for use.

  1. Connect the hard drive to a USB port on your Mac.
  2. Open disk utility.
  3. On the left side of the disk utility window, select your external drive (or one of its partitions).
  4. Click the delete or delete button on the toolbar.
  5. On the Format menu, choose Mac OS extended (journaled).
  6. Type a name for your drive, and then click clear.
  7. After that the drive is deleted, close the disk utility window.

  Once the disk has been reformatted, try to connect this back to the airport Time Capsule to see if it is now recognized.

  Have a great rest of your day!

• How to work with files of database on an external hard drive (USB 2.0 or 3.0)

  I have Oracle 11 GR 2, installed on my laptop. I would like to create an instance of the database on my laptop, but putting the data files on an external hard drive (USB 2.0 or 3.0). The external hard drive will be still attached to the laptop, whenever the database is used. This is going to be a development machine, recently developed a prototype. Laptop is limited to 150 GB on the local disk and I want to have a database of 1 to on this subject. Is this possible with Oracle 11 g for Windows XP SP2?
  I assume that a device attached to the network storage NAS would be the best solution, but I can't fix on my local network.

• Iomega Portable hard drive now does not appear under "Devices" after accidentally deleted USB cable. USB

  My Iomega eGo Portable hard drive was connected by USB on my Macbook Pro OSX 10.9.5 cable and I was transferring my iPhoto folder.  Unfortunately, the cable dropped and I got a message on my laptop hard drive had not ejected correctly.   I reconnected it the cable, but now, it does not appear under devices in the search page.  I also checked the disc utilities and it isn't here either.  I tried to connect the hard drive of my iMac, but it does not appear in the devices out there either.

  Although I have been using a Mac since they first appeared on the market and can usually work things, I find it more and more difficult with all the new technology.  Everything that used to be so easy, one of the great things the Mac since MS-DOS.

  If anyone can help I would be very grateful, because I have a lot of files on this disc of old Mac and use the Iomega to backup my most important files.

  The drive may have failed.

  Try different USB cables.

  Remove the naked drive from the iOmega enclosure and test it in a known functional wardrobe.

  Ciao.

• External hard drive USB, not received a drive letter in Vista 64-Bit

  I do not use my BeyondMicro 160 G external hard drive a lot just to make occasional backups, well this time was different.  I have powered the drive, plugged the USB cable into my PC and normal tone was heard, but NO drive letter is assigned to the drive.  In fact I couldn't find anywhere in my computer that the unit was even detected.  I Visa Ultimate 64-bit, I tried to uninstall the drivers in the Device Manager and rebooted and still no external drive, any suggestions?

• External hard drive USB

  Primarily for backup purposes, I have connected via USB, a new external hard drive to my Compaq Presario (using Windows 7) but I don't see how to access or use. Removal and replacement of the plug USB produce noise sound from the PC that I expect.  Start/computer shows no signs of the element. Start/devices and printers displays an icon for the item, but clicking on it gives no response.   Where should I go from here?

  AHA!   I think you're right about that!   The power, I mean.   It ran OK on laptop from a friend and I tried all the USB ports on my PC but with no joy there.   I think the answer will return for an Exchange or a refund and get a different model.

  I return it for an Exchange/refund and get a USB 2.0 in this case.

• External hard drive USB not recognized by Win XP Satellite

  My Satellite S105 running Windows XP Professional SP3 works well with any external SSD.

  Yet my external USB hard drive from Seagate Freeagent is visible sometimes and not others. The Seagate works very well except when it is invisible to Windows. Removing the drivers USB (re-installed by windows) does not change this. The drive is not visible in my computer or elsewhere. Dirve of Seagate Manager does not detect the drive in these moments there.

  What is the solution?

  Thank you.

  I guess that other external USB devices (USB flash drive key, mouse, etc.) are working properly and don't disappear in my computer. Is this good?

  This means that this issue has nothing to do with the laptop or USB ports for s laptop but with your external USB HDD.
  A maybe it's some kind of problem with the USB HDD. ?:|

  It is a sign that the reader reaches the end of his life?

  Thanks for your help

  Hello

  Perhaps the reader reaches the end of the life, but at the moment it is not easy to say...

  Have you tried another cable to the HARD drive? Maybe it's just a problem of cable s.
  In addition, you should check the HARD drive on another computer or laptop. So you can make sure if it s a USB issue or not.
