• Windows 7 Pro Backup can not see my USB external hard drive.

  This seems to be an old problem, maybe someone has a solution:

  I have a Toshiba 150 GB NTFS USB 2.0 external hard drive I used as backup when I had XP, but now I have W7 Pro 64-bit (SP1), and the backup program is unable to see the player.

  It shows in Explorer, it works very well, has write permission, but is not in the list of Backup Options.

  Player is 18 months old. W7 found and installed the USB driver for it.

  It is wired, I don't have a network.

  In addition, Windows cannot format the drive.

  I changed the drive letter of that W7, named F to Z, no go.  All I see in the backup is C and the DVD player.

  It has been suggested that I have uninstall all the drivers USB and reboot and let Windows reload them, but I have a keyboard and a mouse USB, so if I do that has no way to control the computer.

  How can I make the visible external drive for the backup program? Any help is appreciated.

  I use Ghost on my 8 month, Toshiba Satellite L755 and have never seen a conflict.  I also have it on 3 desktop computers.  For antivirus I use AVG free on 3 systems, Symantec SEP on that and Norton Security Suite on the laptop (which I get for free from Comcast).  The only thing related to security, I see in the menu start from Ghost 15 is a small window to give people access to Ghost.  He also built in the feature called Threatcon, which I've never had any message of.  Here's the info of the construction in the help.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  On Symantec ThreatCon

  ThreatCon is threat of Symantec early warning security system. When Symantec identifies various threats, the ThreatCon team adjusts the level of threat. This adjustment gives people and adequate warning systems to protect against attacks and data systems.

  When you activate the trigger of Symantec ThreatCon to a selected backup job, Norton Ghost detects changes in the threat level. Your computer must be connected to the Internet, at the time. If the ThreatCon level is reached or exceeded, the backup operation in which you have enabled Symantec ThreatCon is started automatically. You have then a recovery point to use to recover your data to your computer should become affected by the latest threat.

  Note:

  If your computer is not online, then it is not sensitive to online threats. But if you connect your computer to the Internet at any time, it becomes vulnerable. You don't have to enable or Disable Symantec ThreatCon when you go on or off line. Works if you're online, it doesn't matter if you're offline.

• Computer laptop (Vista) does not take account any new working USB external hard drive

  Hello, I'm under the latest version of Windows Vista Edition Home Premium on a Dell XPS M1210 and spin in the problems with the connection of my second USB external hard drive. In other words, when I plug the drive (a Seagate expansion 1 TB), nothing happens. Literally nothing, no notification of installation of the driver, no sound is played stating that the system recognized the device, no new entry in post working or disk management. I connected this drive on another computer running Windows 7 and it worked without a problem, so I do not suspect the problem to lie in the hard drive, but with my computer. My other external hard drive USB, a Maxtor Basics Portable 250 GB, works perfectly, but there more than two years. I bought the 1 TB Seagate as a backup and an upgrade, but I plan to go back now that there is nothing more than a big black Clipboard with a green LED clear too much room. What can I do about it?

  Hello
   
  Most likely, there is not enough power for the USB port of your machine to the external device do recognize. As a test I would have you test the issue on another USB plug.
   
  I recommend you contact you either OEM (Original Equipment Manufacturer) or the manufacturer of the motherboard if it is a machine of casting House and get the latest chipset drivers for your motherboard.

• Response speed - USB external hard drive

  Hello

  I have W7 Professional (32 bit) installed on an Acer Ferrari 5000 with 4 GB of RAM. I have a 1 TB WD My Book USB external hard drive connected via USB.

  When I access the drive to play an Explorer of W7 film shows my folder & first screen load files instantly, but then the green progress under the full path bar direcory slowly starts to move across the screen and may take up to 3 minutes to stop. Durning his time my pc performace Marc everything stop. The video load but Windows Media Watch does not respond and the hourglass (or a circle in W7) shows the application as it is busy. Finally, video begins to play but jumps several images at once, even if the sound is fine. After about a minute the video started playing at double speed, befire the entire process repeats itself until it catches up with the sound and the video will play very well for about 10 minutes.

  Videos are not damaged (I can play my portable hard drive very well), the device signals healthy in the WD diagnostic tool and the firmare for the device is up to date (on the WD site).

  I see a lot of people in this forum have problems with W7 64 bit, but there is no mention of 32-bit issues. Also there never was problems with the device was detected or is not accessible - gal just access the device. My only job is about from the drive to copy the movie on my laptop and play it from there - which kind of defeated the purpose.

  I left a similar post on the WD website, which so far had no response. Is it a question of W7/USB? Any other ideas would be useful.

  Speed on USB hard drives is relatively slow at first. You are looking at maximum read anywhere between 25 and 32MBs speed if the CPU is not do much else at the time. Supported playback mode tend to transfer bog down over time, as the fragmentation of the file. USB is convenient but firewire and eSATA are faster and faster.

• Satellite 1800-712 does not recognize my USB external HARD drive

  Hello

  I would really appreciate the help. I own a satellite 1800-712. I have receently bought a usb external hard drive for some extra memory (IE Toshiba MK4026GAX USB Device)

  When I connect it to my usb port it records any with the computer. The green light so there is power to the hard drive. The usb ports recognized of other fine features (a modem and memory stick)

  I tried the external hard drive on a desktop pc and it works fine.

  I have downloaded all windows xp service pack updates and updated my bios. Don't know what to do now.

  Please help and thank you in advance!

  Hello

  Although sometimes, I know that the OS is not able to recognize the external USB device, because the device external USB (HDD) consumes more energy than the 500mA.
  The USB ports provide 500mA power and if the device needs more power so it s is not possible for the Windows operating system to recognize the external device.
  You have an external power supply for the USB HDD? You should use it.

  Good bye

• How can I save my backup external hard drive?

  I have a La Cie 4 to external hard drive to back up my MacBook Pro. How do I backup my external hard drive (just in case ceases to work properly or at all)?

  You use this drive as a backup Time Machine?

  You can connect as a second external hard drive and configure Time Machine to use this drive as well. Then Time Machine are displayed alternating hourly between readers. So when one of those falling down, you will have a backup that is more than an hour old.

• Installed new hard drive on laptop with Windows 7 can install Windows XP on external hard drive and plug it into USB?

  Original title: Win7 Pro + HD Ext different OS
  I just installed a new hard drive in my laptop with Windows 7 Pro 64 bit.
  Would it not be possible to install WIn XP or Win 98 + older software (Win 98 or XP) on an external hard drive, then plug it into USB, laptop, in order to run old programs of 16-32 bit?

  It would be best to run Windows 98 or XP in a Virtual Machine, if you need to run older programs.

  You can use a free software such as Oracle VirtualBox or VMware Player:

• Can I use my old external hard drive after replacing SSDS?

  I recently bought a replacement of SSD for my hard drive.  A friend suggested I have get a box for the old man and keep it in a backup or extra.  I was wondering how difficult that would be, and I would be able to run applications from her?

  -Matt H.

  Yes, your friend is good, just buy a USB box for this and then you, it's like any other external hard drive. You can get these 10 pounds and more, but you get what you pay for.

  Simply open the screw in the naked reader, plug, close the case and you are done. It's very simple to do.

  Hello

  Seems that the external HARD disk drive cannot be recognized because of the driver problem.
  What you could do to disconnect the USB of ALL devices and open Device Manager.
  Then choose the display command, show hidden devices and uninstall all devices under USB controllers. Reboot the laptop.
  After restarting again the operating system must install USB drivers again and you could test whether the external HARD drive can be connected as well.

  I have goggled a bit and found a few interesting statement abut Cypress AT2LP RC58. It seems that the HARD drive is ok but sometimes the HARD drive cover and the interface connector would be malfunctions and so this problem would happen.

  But these are only suggestions if you want to try for Cypress AT2LP RC58 goggle and see for yourself.

  Best regards
