  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.

  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.

  Your daughter have a Mac and use Photos? If so just copy your library of Photos to SMT, it must be formatted OS X Extended (journaled) with the defined property is ignored. Then she can use the SMT library or copy it on his Mac.

  If she doesn't have a Mac do the following:

  1 - Create a new folder on the external drive.

  2 - Select all photos in the library (in the window of Photos).

  3. Select the file ➙ ➙ export export Original unmodified for XXXXX items menu option.

  

  4. in the format of subfolder select Export window = name of the time

  

  5. in the next window, select the folder that you created on the external drive as the destination of export and export all your photos to this. Photos at every moment in your photo library will be put in a folder with the date of that moment and this issue will be put on the EHD in the folder that you created.

  Recently, I noticed that my CD/DVD stopped working. He turns, but nothing happens; the disc is not read.
  I use Windows 7 Home Premium 64 - bit on an HP Touchsmart tx2z.

  I ran the Microsoft FixIt program through http://support.microsoft.com/kb/982116 and it has identified the following problem: 'HL-DT-ST DVDRAM GT20L periph. CdRom SATA has a driver problem. The driver faces a problem of Plug-and-Play device. »

  I manually uninstalled the driver in Device Manager and then scanned for the hardware changes. The driver was reinstalled, but with the same problems as before.

  Any ideas?

  Also, try following the steps for Windows Vista, which should also work in Windows 7, in the MS KB article:

• 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 recognized as a drive in Windows 7

  My external drive was not functiononing, so I formatted it recently. I gave him a normal speed format, using windows only. It is an external hard drive, 256 GB, connected via USB 2.0, formatted to NTFS.
  After it was over, windows began to recognize the local drive, making it impossible for me to remove it safely (he does not give me the opportunity to do).
  My concern is that it can affect some of my files if I just unplug the unit. I googled but didn't find any results that worked for me.
  Any ideas for what to do? I'm not really good at these things. but I really need my perfectly functional hard drive.

  It is normal for hard drives, they are USB drives physically internal or external, and the "Local Disk".

  • Open the Device Manager (start, type "Device Manager" (without the quotes) in the search box, press enter)
  • Expand the category of "hard drives".
  • Right-click on your external drive and choose 'properties '.
  • Click on the tab 'Strategies '.

  The default value for the drives connected by USB is 'Fast moving' which, as the option explains "disables the cache on the device and in the entry window, but you can disconnect the device safely without using the safely remove hardware notification icon."

  Or you can choose the "Best Performance" which "allows the cache in Windows for writing, but you must use the remove hardware notification icon to disconnect the device safely."

  Make your choice, click OK, and're you good to go.

• 400 GB external hard drive USB (PX1273E - 1 40) is internal SATA or IDE?

  Hello

  I consider burning this external hard drive (PX1273E - 1 40) and would like to know if the disk inside has a SATA interface or an IDE interface, in the case of the latter in I decide to open, take the drive and connect it to the computer internally.

  Anyone know this information?

  Thank you.

  Hello

  Unfortunately, I didn't find all of the information on the interface type of the enclosure.
  In my opinion, it could be an IDE interface but I m not100% sure.

  But never fear, you can buy a 3rd party SATA to IDE adapter and was able to connect the HARD drive if it will support different interfaces.
