Question about Hitachi PC Desktops

2 Answers

My external hard drive (HD) simply stopped working, should be no disk reading/ writing problems, the power is getting to the HD, but not to the drive as it does not spin, so from my own personal knowledge on the subject, I believe the problem is one of two things; firstly it is either the logic board on the drive itself has stopped working or secondly that the platters in the motor of the drive are jammed/ stuck. Can you help me? ps~ already contacted Hitachi and retailer.

    Thanks for your help, I've done a quick google of the "usb drive data reader kit" - it brings up a few suggestions here and there, but have you anything in particular that you could recommend, a link to this info would be great! Also, I'm not sure if this would affect the device recommended, but I am using a mac based platform.

    Many thanks for your help... it truly is invaluable!! :)

If it's not spinning most likely it has fried PCB or bad enclosure.
You can try to remove the internal drive from it and connect it directly to PC. If still not spinning then the problem is with logic board. Try to find another drive of the same model and replace the card. But as far as I know most often it doesn't work.

Sorry, but no spin, no win! Your hard drive enclosure has encountered a sever knock to cause headslap in the drive. You can rescue the data by purchasing a usb drive data reader kit. You take the drive out of the enclosure, attach the cables and plug it into a usb 2 port. You should be able to read the data no problem. Make sure you connect all cables to the drive, and it should be problem free for you.

How to Install an Operating System on an External USB Hard Drive:



You may have an external hard drive you want to use for more than just document backup.
In this situation, you can install an operating system onto your external hard drive. By doing so, you will be able to run your external hard drive as a fully functional operating system.
If your primary hard drive ever crashes, you will have a backup option unavailable to those who simply use their external hard drives as file and document backup.

1) Plug your external Hard Drive into your Computer using the USB cable. Insert the installation disk for your Operating System into the CD/DVD Drive. Turn on or restart your Computer.

2) Boot from the installation disk. You may have to press a key once prompted to boot from the installation disk.

3) Accept the license terms and conditions. Read through these carefully if you wish to understand your legal rights as a user. If you disagree with these terms and conditions, you may want to purchase a different Operating System.

4) Choose your destination drive. Your external Hard Drive will likely be the E: or F: drive. By default, the C: will represent your main Hard Drive and the D: will usually represent your CD/DVD Drive.

5) Begin the installation. Your external Hard Drive will install the Operating System. You will now be able to run that Operating System off of your external hard drive.


Hope this helps.

Cant detect hdd


Hi Martin...

The problem is being caused by the Logical Disk Manager
Administrative service and possibly the logical Disk Manager service
not being started or the services might be disabled. to solve the
problem, click on the "Start" menu, click the "Run" command, and then type
in the box: services.msc , scroll down until you see both the above services.
right click on each of the services about and select properties, on the
general tab, change the startup type to "automatic" and click the start
button under the service status. do this for both of the services, and
that should will fix your problem."
-------------------------------------------------------------------------------------------------
For Windows 2000 and XP:
Right click on My Computer.
Choose Manage (This will open the Computer Management window).
Go to the Storage category and select Disk Management
Right click the new drive (usually listed as Hard Disk 1) and "initialize"
You now have the option to partition and format the drive.
The default settings of Primary Partition and NTFS- Quick Format are recommended for most users.

-------------------------------------------------------------------------------------------------
External hard drive can not be recognized, are more common on computer
failures, what's the reason caused this failure?
1, Setting the CMOS parameters
If you never used the USB external device, there may occur the case:
The system can not detect USB hard drive even if the driver is properly
installed, which was mainly due to the motherboard CMOS default port is closed, if not set to
open state, it naturally Windows can not detect the external hard drive. In order to solve this
problem, we can re-boot into the CMOS settings, and set "Assign IRQ For USB" to "Enable" in
"PNP / PCI CONFIGURATION" column, now the system can be assigned to the USB port available
interrupt address.
2, Power shortage
As the USB drive need to consume some power when it at work, if directly through the USB interface
to take power, the power supply may be not enough. Thus, almost all of the external hard drive
comes with a separate external power supply or a PS2 keyboard to take power transfer interface,
at this time you should connect external power supply or through the transfer cable ps2 connected
to keyboard to ensure that it have provided adequate power to the external hard disk,
recommended that you should ensure the external hard drive have adequate power supply when you
use it, otherwise, the external hard disk is likely to be damaged due to insufficient power
supply.
3, USB extension cable fault
USB interface type does not match the external hard disk interface ,this case caused it can not
be used. For example the standard USB interface of the computer configuration is 1.1, while the
external hard drives purchased are USB 2.0, which requires the cable connected computers and
external hard disk must support USB 2.0 standard. Because high-speed mobile device plug in a
low-speed hub, the device may not be properly installed, and some people use external hard disk
while using USB flash drives, For convenience, they directly used USB 1.1 standard cable that
supplied by USB flash drives, as a result, the USB 2.0 standard hard drive not be recognized
correctly. Just replace it by the USB 2.0 standard cable can solve this problem.
4, Windows version is too low
Pre-Windows 98 operating system does not support USB peripherals, so in any case to install the
driver, set the CMOS parameters are unable to make normal use of external hard disk. In this
case, one solution is to upgrade the operating system up to Windows 98, another way is to
Microsoft's official site, download the appropriate patch to make it can identify mobile hard
disk.
5, The system is set incorrectly
When installed driver, the external hard disk icon will be seen on the Device Manager for some
Windows 98 users, but the Explorer does not include the corresponding letter identification,
which is improper system settings. In the Device Manager, double-click the Hard Drive icon, and
click the pop-up window in the "Properties" button, and you could see disconnect, could be
deleted, synchronous data transmission and Int 13 unit four options, of which "could be deleted "
is no tick in front of the system, and simply check this option to restart your computer, you can
see in the Explorer, the new external hard disk drive letter.
While the failure of the external hard disk does not recognized are more the reasons, but
generally not the USB interface or external hard disk's own fault, so it requiring us to consider
some more from around the association when exclude it, I believe you can successfully use the
external hard disk.
--------------------------------------------------------------------------------------------------
Hi I had the same problem and solved it like this assuming that you are running windows xp

With your external casing powered-up (it does not get power through USB does it?) and your WinXP
PC running, plug in the USB.
You should hear 'chime', what happens then?
If harddisk is recognised here, but does NOT have a drive-letter and cannot be seen in Windows
Explorer, the answer is in Windows Disk Management
...
Go Administrative Tools > Computer Management > Disk Management. ( on left column)
Maximize this page. Physical Drives appear at the bottom; Logical Drives at the top.
Hopefully your drive will appear at the bottom (physically), you must then 'import' it into the
Windows installation
; Windows will put its 'signature' on the drive and assign it a logical drive letter :^)
you can try to format it here if it is new and has no info on it , check back to My computer and see if present.

When i login my computer I just get black screen try to reset or confiuate says primary and scondary drive 1 not found


HI Dear,

This is a hardware related issue. This might be due to following problems :

1. The data cable that connects your hard-drive to the mother board might have picked up some fault.

2. The mother board is not working.

3. The Hard-drive might be corrupted.

To see what exactly is causing this. Remove your Hard disk and try to on your friends computer. If its working fine then its the other two issues.
To check for the mother board and the data cable. remove the hard drive aand try t with another one. If the motherboard reads this hard drive then it is sure there is no issue with the motherboard and the data cable.

Now if trying above you see that HD is not detected. then replace the data cable and then try the HD on your computer. If it reads then there is no fault in *********** board. So replace the data cable and get a new one.

And if it does not reads then the motherboard have some issue. In that case i would suggest you to take your comp to nearest service station.

hope this works out. If it does not and if you have more queries that need to answered then please do write to us once again.

Have a nice day.

Emachines pc keeps saying hard drive is failing


What kind of resources are you pulling on the pc everyday? For example are you doing heavy writing to the drive everyday such as video editing, ripping etc and how much air flow is your pc getting. If the case gets too hot or warm for long periods of time it can cause the hard drive to fail quickly. Lastly check your power supply male sure its pputting out the proper voltage to the computer specifially the connection to the hard drive. If its not stable the nit will cause your hard drive to fail.

Hard Drive Install gone bad!


Unplug the slaved hard drive.

Restart the computer. If you get the same results.

Pull out the cmos battery on the motherboard. Most look like shiny nickles, be carefull not to damage the board. Make sure you unplug the computer first and let it sit a minute or two afterwards before putting it back.

That will set the bios back to defaults and you should be able to get the computer up and running from there.

As far as slaving that drive to be used as extra storage, you might want to consider an external enclousure instead.

Best of luck.

Hello. It sounds like your external hard drive has crashed, or is getting ready to crash. If you can back up your data, you should do it now. If not, you should get your drive to a professional as soon as possible.

I'll monitor this thread. If you have any more questions, please feel free to ask.

I have a iomega mdhd500-ue for about past ten months.when switched on it useually whirls into action but now it is just making a repeated clicking sound and it is not connecting to my laptop


I have a MDHD500-N Iomega external HD that had the same issue - clicking at startup and flashing power LED. I noticed that the supplied power transformer for the unit is 12V 1A and the sticker on the HD enclosure says 12V 2A. I hooked up the HD enclosure directly to a power supply - at boot up, the HD draws 2.5A, more than double what the provided power transformer can output. HD enclosure runs beautifully on an external PS.

I am shopping for a external hard drive; I am not sure I understand the difference beween 5400 rpms and 7200 rpms. I have an xp home opperating system that might be slowed or stopped altogether.


rpm = revolutions per minute
meaning, the number of rotations a disk makes
the higher the number the faster the disk rotates.
which translates in to faster writing and reading of data.

If you can afford it, I would recommend getting an 7200 rpm drive.
