Win XP wont recognize the 400GB USB external HDD

I just bought a external 400gb hdd from toshiba,
usb 2.0
no psu
says plug and play right on the box and windows xp wont recognize it.
The little blue led comes on, but nothing works at all.
The only thing that happened once, is I THINK xp recognized it as an MTP device.. which I got updates for, but still nothing.
I updated all my drivers, nothing seems to be working at all.
Please let me know how I can go about making this work.
Thanks

> The only thing that happened once is I THINK xp recognized it as an MTP device which I got updates for, but still nothing.
What MTP means exactly?
Did you check if the external HDD needs an additional power supply?
Did you test it on different computers/notebooks?
Did you try to remove the HDD hubs and controllers from the device manager and rebooted the notebook in order to reinstall this devices??? If not -> do it

HT204350 Why won't my MacBook Pro recognize the connected USB external drive when trying to 'Transfer Information to this Mac'?

I recently bought a second-hand MacBook Pro (mid-2010, i7, I'll call this New Mac). I want to transfer my accounts and data from the first MacBook Pro (mid-2010, i5, I'll call this Old Mac). I took a Time Machine Backup of the Old Mac, using an external USB drive. After erasing the drive and installing Maverick on the New Mac, I attached the USB drive to the New Mac and began the setup.
At the step "Transfer Information to this Mac", the Mac just gives me a nice spinning icon next to "Looking for source...". Apparently it cannot find the USB drive.
How do I fix this? I don't want to setup a new user on the New Mac, I want to migrate my old users from the Old Mac.

See if you can inherit the backup.

Another option would be to clone your old Mac and copy the clone. That would leave your old Mac with a backup and you can start a new one with the new Mac.

I upgraded my imac to OS Mountain Lion and now the Seagate Goflex external HDD is not recognised

I upgraded the iMac to Mountain Lion and it does not recognize the Seagate Goflex External HDD that I was working from earlier. I do not want to buy a special program since the Goflex HDD was working on both mac and Windows without any problems before the upgrade. The Goflex HDD is still working on my Macbook pro so there is no problem in the HDD. Is there something that needs to be activated... Please help

A bit more info for those of you reading this.... the problem seemed to be in iTunes. For each connected device , if I clicked on the Photo option I could no longer select the second radio button for limiting the photos by Events, Albums, etc. It was an all or nothing deal. But selecting all would cause the error.
So I had read the other forum posts about the "&" symbol being the cause of the problem. I went through iPhoto and made all of the changes. It did not work. I then looked at iTunes, using the AlbumData2.xml file listed in the other forums as a reference. I found one album with the "&". I edited that one. Still would not work. So then I spent 3 hours on the phone with AppleCare last week. I talked with 4 different advisors. None of them had heard about the "&" error from the forums. We tried everything in iPhoto including repair and rebuild. Finally we created a whole new library and reimported my master photos from my original one. Using this option would allow me to now check off that radio button in iTunes. BUT... I now lost all of my albums and events and would need to rebuid them. I was not happy. They agreed and we set up time to talk this week.
So today I talked with AppleCare again. They now have more info and said the problem has to do with iTunes and the new iPhoto 9.4. It does not like the "&" symbol anywhere in either iPhoto or iTunes. So they now have me going through everything in my iTunes library. Genre is OK but any other item cannot have " & ". I have several dozen to edit and will do it over the weekend and then restore my original iPhoto Library and see if I can finally get it all to sync. I will let you know how I make out, but apparently you need to eliminate " & " from every entry in iTunes and iPhoto.
Quality control is not up to par with Apple these days.

So I formatted a brand new hard drive to MAC OS (Journal), I then could save on the hard drive. Not two days later Im back at square one, the program wont recognize the hard drive again.

So, hard to beleive, but I am having some trouble with Final Cut Pro X.
This last week I formatted a brand new hard drive to MAC OS (Journal),
so that I could save on that hard drive.
Well it went great.
I saved my project on there and copied a few others over as to free up space on my Laptop.
Then, not two days later Im back at square one,
the program wont recognize the hard drive.
It wont even open the events up off my hard drive,
as to jog the program into reqcognizing the scratch disk (which worked twice before).
What happened?
How do I get the program to re-recongize my newly formatted hard drive?
Please help!

The name of the drive, or the name of some folders inside the drive, may fool FCP X into believing it is a camera.
Also, you should not use the drive for time machine backups.

Without providing details on exactly what you did it is hard to provide an answer. It's like me saying, "This chocolate cake I made tastes wrong," but not providing the recipe for review. Maybe it was the garlic in that particular recipe.
If iTunes is successfully using a previous library which you rename to iTunes Library.itl then that is now the current library.
Have you restarted your computer and then tried emptying the trash?

Installation of Windows 7 via USB External HDD (Boot Camp Assistant)

How do I mount Windows 7 Ultimate disk image (.iso) onto my USB external HDD so that I can boot using that USB external HDD? I have tried reEFIt, but it doesn't work for me. It may be because I did something wrong. I would appreciate a comprehensive guide. Thanks.

i suspect you haven't prepared the USB drive as a boot volume.
You can absolutely do this. It is detailed on CNET in the following article: http://reviews.cnet.com/8301-31012_7-20020513-10355804.html

Automount of SD card & USB external HDD with strange KDE pop up msg

Today I reviewed lots of threads posted over the last year and some bug reports too about this issue, but it's happening for me too. Both SD card and USB external HDD have autodetectable filesystems on them because I can mount them by hand with "mount /dev/mmcblk0p1 /mnt" and "mount /dev/sdb1 /mnt". But it would be nice if I didn't have to do that.
Although I didn't notice which explicit install that I did pulled them in as dependencies, I do have udisk2 and polkit installed. Also installed udiskie as a wrapper. I've been mounting these volumes by hand before now because I feel like I'm still learning the ropes of The Arch Way and guessed (apparently incorrectly) that mounting volumes by hand was just part of "The Arch Way". But based on some threads here and some bug reports, I guess this used to work in Arch but has been causing some problems for some people lately when they upgrade. I just installed Arch for the first time (using the 2015.02.01 iso image), so I don't have any background to go on.
So what is The Arch Way for automounting external drives? I've skimmed the wiki article for this and because "Development of udisks has ceased in favor of udisks2." it seems that udisks2 is preferred. But it got installed and the daemon is running for me. The user is in the wheel group. dbus is running (though like one person who filed a bug, I too have several instances of dbus in my ps -aux output and I'm not sure if that is as it should be or not). I've done no special configuration ("not wittingly" anyway; I promise, my name is not James Clapper) that I think would have affected this.
So for a newb with no special preference, how should automounting be configured in a new Arch system? In other words, what should be my first steps in trying to solve this problem for myself? I know there are lots of different ways to skin this cat, but I'd prefer the simplest and most elegant solution that does not depend on KDE or GNOME or other unnecessary tools. I've just (with this Arch system I just installed) begun using i3wm and I think I'll be sticking with it. That said, however, it's clear that I inadvertently/unwittingly managed to get some elements of KDE into memory as the following http://gamonics.org/img/2015-02-26-1731 … _scrot.png shows. This popped up both times, when I plugged in my SD card and when I plugged in my USB drive. Any thoughts on what's going on here? I did install okular explicitly because I think it's one of the best PDF viewers, but I don't understand why KDE is reporting anything to me when I'm running i3 and insert an SD card or a USB disk.
And in the terminal, I get this output (apparently from udiskie):
[root@archippocrates archie]# Failed to show notification: The connection is closed
not adding /org/freedesktop/UDisks/devices/mmcblk0: unhandled device
mounted /org/freedesktop/UDisks/devices/mmcblk0p1 on /media/3532-3338
Failed to show notification: The connection is closed
Although the volume does get mounted automatically.
Thanks for any thoughts.

I personally can't answer the question of "simplest and most elegant" way of mounting devices. It all depends on what you want. If you expect more exotic functionality, say correct unmounting of devices if they were disconnected during a sleep cycle, there's probably no way around udisks2. For that you get a complex piece of software prone to... unexpected behaviour. Mind you some of it is related to front-ends like GVFS.
As to your KDE issues, last I checked mount handling was disabled by default there, but you can control it manually (see man kcmshell4). Though I haven't followed up on KDE 5 developments. If going with udisks2, I'd recommend using devmon from the udevil package as a front-end (more details on the wiki udisks page).
PS: multiple dbus instances are expected, check the user names and specified arguments in the ps output.
edit: grammar. :X

USB External HDD Enclosure with a 500GB HDD!!

Hi All,
I was just wondering if anyone has come across using a 3rd party USB external HDD enclosure with a hard drive (mine is 500GB HDD). What I am trying to do is to format the HDD so both PC and MAC can use it but it will be mainly connected to my iMAC. I have tried by using PC to format the HDD to NTFS but MAC will not show the HDD on the desktop when I plug the USB to the back of the iMAC.
I have done some researches and it seems the only way to do make this possibe is to format it into FAT32. So I have tried to use FDisk to make the partition but it doesn't seems to support anything bigger than 120GB, now I am really stuck. If anyone knows any quick and painless solution, please spare me some advice.
Headache!!

Windows can use, but not format, large FAT32 partitions. Microsoft wants to discourage using FAT32 for portable storage (for marketing reasons).
The solution is to use Mac's Disk Utility to format the disk as FAT32 (misnamed MS-DOS in Disk Utility). The disk will then be read/write by both Mac and PC.
Also, it's worth pointing out that you can read and write NTFS disks using MacFUSE with the NTFS-3G plugin. Albeit, this is very awkward to do unless you've got some UNIX shell experience.

Is it possible to make OSX see the internal and external HDD's as one large drive?

Is it possible to make OSX see the internal and external HDD's as one large drive? For instance, hypothetically, could I have a Mac Mini Server with 2TB of internal storage and 2 external 4TB Thunderbolt HDD's, and make the OS see them all as one large 10TB drive?

Yes it is possible to do this, but this is not recommended since a disconnection of the external drives would lead to a destabilized system. Its best to do this only with internal drives, or secondarily with only external drives that are set up separately from the boot drive.
However, if you do wish to do this then you can combine any local set of volumes into one large "spanned" hard drive using Apple's CoreStorage volume management service. It does take a few steps to set up and requires use of the Terminal and Disk Utility. Here is a tutorial on how to do this: http://reviews.cnet.com/8301-13727_7-57550128-263/how-to-make-a-custom-corestora ge-drive-in-os-x/

Windows 7 64bit doesn't recognize the USB External HDD Stor E art 3.5"

I purchase the External HDD Stor E art 3.5" and pass a few days the windows don't recognize the HDD. Try to connect the drive to other 2 USB ports and nothing happen. Use a USB pen drive to see if was a problem with the USB ports but all 3 are OK. Try it on the Asus notebook and windows 7 recognize the HDD. I formated the HDD in FS NTFS. In the disk managment don't show the external HDD. What can I do to resolve this problem?
My notebook is a Qosmio F60

One last thing you can do about that.
Install OS again using original Toshiba recovery image. After doing this you will have clean preinstalled OS and everything should work well again.
If the same will happen again you should contact nearest Toshiba service and try to clarify the situation.
I know it is pretty radical solution but, believe me, most effective to check notebook functionality.

ZEN MICRO, USB wont recognize the device

Hello, I recently bought a Zen Micro, and I plugged it in via the usb cable, and installed the drivers for it. After installing the drivers, I clicked on Zen Micro Media Explorer, and it said to please plug in your zen micro. The player functions, I can go through the menus and things, but my usb will not recognize the device.. HELP? I also went on the site and got the latest drivers. I also tried it on a different computer, with the same result. Did I forget to install something? 

what i did when I first got my zen micro, as the instructions said, to insert the installation CD and install everything before plugging in the zen micro.
maybe you can try deleting everything, then reinstalling the software from the installation CD then plug in your micro to see if that works...

Toshiba 500gig usb external HDD disconnects at the drop of a pin

Hi,
I have one of the new USB powered portable usb drives from Toshiba. It is a 500gig unit. It has worked flawlessly up until about the last couple weeks. Since this time is disconnects very easly and sometimes is not useable because it disconnects too much. Is this a common problem with these smaller drives that connect with the regualr usb cord, and is there any fix for it?

Some people find that these types of drives need more power than a single usb cable can supply. The Western Digital Passport also has this problem. Using a Dual USB cable helps a lot in this situation by drawing power from two USB ports instead of one.
Addendum Friday 1:30 PM CDT: Just make sure that the dual cable you get has the correct plug for your external hard drive. The one I linked to above works with the WDC Passports, but I do NOT know if it has the correct plug for the Toshiba External Drives. I would advise against using one that works as an extension to the existing cable as the additional connection combined with the additional length would probably defeat the purpose due to the power loss they would bring into the scenario. You need a cable that attaches directly to the USB ports on the laptop and the external drive.
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

DV8000 Hard drive issue - wont recognize the hard drives

This is my first post so please let me know if I do anything wrong!
Ok so the other day I was working on my dv8000 when it just powered down. I turned it back on and instead of booting properly it told me that it could not find the operating system. Knowing that the machine had two drives in it, I swapped the primary with the secondary and still got the same result. I then went out and bought an external drive bay and attached the primary hard drive to my desktop. The drive was bad and kept cycling the heads. I have now bought a brand new hard drive and the laptop is currently configued with the new drive in the primary slot and the other original hard dirve that I checked and is good in the second slot. Here is my problem - when I go into the bios the computer recognizes the two hard drives for boot options but when I try to load XP from a cd to the laptop, it tells me that there are no hard drives installed... what am I missing? I have checked the drive for errors via the bios and the test come back passed. I thought about formating the drives but the the bios does not have a format feature in it that I can tell. for all intense and purposes, the bios sees the drives but the operating system does not. Any ideas>
Please help as this is my business machine and I cant keep borrowing my wifes laptop, she thinks I am gonna break that one too!
Thank you.
This question was solved.
View Solution.

That did it! I had to turn off the Native Sata Drive support in the Bios! now the machine is up and running. HP has told me that I need to purchase a replacement drive from them as the replacement drive that I bought from my local store does not have the HP restore partition on it. I can still access the original drive and I do see that it does still have the HP restore partition on it. is there a way to just create a partition on the new drive and copy the files across?
