Hitachi external usb storage drive comes up fine when turned on, but then after a few minutes "detaches" - then it spins back up and shows up - then after a few minutes detaches again. kind of comes and goes - this happened with 2 different drives on 2 different PCs so I'm guessing its the drive - thoughts?

I agree - it sounds like your drive is failing. I highly suggest backing up any important files on that drive before it loses them - I had a similar problem with an external USB drive and only managed to recover 80% of my files before it totally broke down. If it is still under warranty the manufacturer might replace it. If not, it's worth a few bucks in parts. :(

I have a Packard Bell Imedia desktop not sure of the model. It was working fine until recently, I switched on my pc and after the boot screen "NTLDR is missing Alt Ctrl Del" message appeared....


Remove the hard disk and attach it to an USB hard drive adapter and then connect it into the USB port of a working computer. This computer will detect the hard drive as an external storage device, then you can open the various folders and files to copy your files to this computer or burn your data to a CD/DVD disc or USB flash drive.
Return you hard disk back to your Packard Bell so you can reinstall Windows.

Computer not recognizing external Hard Drive


Aren't usb drives fun? Anyway, there are a few points where this can break down. Your external drive is actually made up of a few parts. It has a normal hard drive, and either what is called a "SATA to USB Bridge" or a "IDE to USB Bridge". If it is a full desktop size hard drive, it will come with a power supply that you plug into the back of the drive. If you have a laptop hard drive it can be powered through the usb port.

When you plug it in, the computer should recognize that you plugged in a new device and show you a message saying found new hardware, found usb to ata bridge, found disk drive etc. in that order. If you get these messages and still no hard drive shows up in my computer, then you may need to assign a letter to the drive or even format it. Right click on the "My Computer" icon, then select "Manage". On the right hand side of the window that appeared, double click storage, then disk management. It should list all drives attached to the computer. Your TB drive should show up as a removable disk, and should already have a partition. If it does not have a partition, you will have to partition it. Just right click on the rectangular part (on the right side) and select format. If you cant format it, try right clicking on the left hand side, the square bit, and select initialize. Then format.

If you just need to set a drive letter, right click on the rectangular part and select 'change drive letters and paths"

Here are some other things that can go wrong:

Not enough power, the drive isn't getting enough power and cant mount. Try plugging in the power adapter that came with it or try a different usb port. If it came with one of those funny looking Y shaped usb cables, plug both ends into the computer, so that it can get enough power.

Bad hardware, either the hard drive or the bridge is bad.

Then you need to return it to the store you got it from. If that is not possible you may be able to pull the drive out of the enclosure and use it as an internal drive.

Bad USB ports.

This can be hardware or software. If other usb devices work fine then this is probably not the case.

New Dell desktop can't recognize external hard drive


I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

Assuming that you have installed a fresh windows installation after crash, you might not installed the usb drivers.

to make sure that the usb drivers are installed and correct drivers go to controlpanel->system->device manager.
and check in that no yellow icons are present in the usb.

you said that the red light is on. that is power indicator and no data transfer.

green light indicates power and data transfer is on.

check your drivers and try to update or reinstall if the drivers are already present.
CAUTION: before reinstalling or updating see that you uninstall the previous drivers.

It's possible something was damaged on the interface board inside the case, or on the drive itself. If you listen to the drive and it sounds like it's spinning up normally when you turn on the power, it's probably the board. I haven't had it happen yet on my WD external drives (I have two), but I have seen 3 Maxtor brand external drives with that problem. The drive itself was fine when put into another external case.

I have seagate free agent 500gb when i plugged it 1st time everything was fine, now windows vista is telling me that cannot recognize it


Power cycle the drive itself; once the interface is reset or the power restored to the external drive, Vista will be happy with it again (I rather expect.) Don't forget to put vibration isolation mounts under your drives if summer construction/excavation is coming.
