Question about Western Digital 500GB My Book World Edition 500 GB Hard Drive

Computer suddenly not reading external harddrive

Up until yesterday, my Simpledrive 500 GB harddrive was working just fine. Now, no matter what USB port I connect it to, my computer isn't reading it. The light lights up and the harddrive boots up when it's connected, and it seems as though it would work, but my computer can't detect anything from it. I've tried rebooting and unplugging it many, many times, but it makes no difference. My other smaller Simpletech 160 GB drive is still working, but the larger one isn't. The 500 GB harddrive is much newer as well; I've only had it about 2 months.

My computer model is an HP a1110n.

I managed to fix it by unplugging the harddrive from the main electrical power source.

I have several computers at home, and none og them can recognize this portable device. Hitachi 250 GB Mod: SDM/250RW


1) Power:

It may be the problem that occurs with a lot of USB powered devices jrherrer. Not enough power provided.

The USB cable plugged into the computer, provides signal wires for transferring information back, and forth, and also provides 5 Volts DC for power. (Two D cell flashlight batteries produce 3 Volts DC)

http://en.wikipedia.org/wiki/USB

[ Below shows the Signal pins, and the Voltage pins of the USB B Mini style connector, (Male), used to connect to the SimpleDrive Mini external harddrive,

Pin 1 is for the 5 Volts DC Positive (Wire color - Red)
Pin 2 is for the D- Signal (Wire color - White)
Pin 3 is for the D+ Signal (Wire color - Green)
Pin 4 is not connected. (Or sometimes joined to Pin 5 with a Resistor)
Pin 5 is for the Ground (Wire color - Black)

Just added info in case you wanted to know ]

From what I see the SDM/250RW has a USB port on the side, and a DC Power Jack, used for an AC adapter, also.
(Round port with a pin in the center)

http://www.hitachigst.com/tech/techlib.nsf/techdocs/0C876B7AB91B23988825773F006BEA02/$file/SD_Mini_DS_final.pdf


From what I see stated from Hitachi, and sellers on the 'net, the AC adapter may not be provided.
Many of those who provide a review state that both the USB cable, and the AC adapter is needed to provide enough power. Seems to be a power hungry external harddrive

It's a 2.5 Hitachi SATA laptop harddrive inside that external case. (The Harddrive is 2 and a half inches across in Width. Common size used for laptops)

When using an external device powered by a USB cable there are general guidelines to follow,
A) The USB cable should not be more than 2 feet in length
B) Connect the device directly to your computer, instead of through a hub, or other device, unless the USB hub has it's own power.


2) USB cable:

Could be a faulty USB cable, although I imagine you have tried different ones by now.


3) Interface Circuit Board:

The Hitachi SATA 2.5 harddrive inside the SImpleDrive Mini SDM/250RW, plugs into a small circuit board located inside that external case.

Components on the circuit board may be fried, or the Harddrive may have come loose from the interface.

Loose from the interface
To explain;
The back of the harddrive has connector pins sticking out.
The interface has socket holes which the pins insert into.

Faulty circuit board
The external case of the SimpleDrive Mini SDM/250RW can be carefully opened up, and the Hitachi SATA 2.5 harddrive extracted out.

Another inexpensive external case for a 2.5 SATA harddrive can be procured, and the Hitachi harddrive put in it.

Example of a 2.5 SATA external enclosure,

My external Harddrive just up and stopped showing up on the computer. I mean the lights (red and blue) are on, it just doesnt show up. i even plugged both cables into my comp, and still nothing. I noticed...


First make sure usb cable connected to harddrive is working fine. try it in different usb ports. Press windows key +R key so you can see run then type in run "devmgmt.msc" then press ok so you can see device manager uninstall all usb drivers then it automatic install usb drivers. then check. Also you need to change registry for that type in run "regedit" then press ok then you can see registry editor then locate below key. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11 CE-BFC1-08002BE10318} And remove upper filter and lower filter.Then restart computer then check. Try your harddrive in different computer if it is not recognized on another computer too then power adapter of harddisk or your harddrive has internal issue.
Let me know if you need further assistance. Thanks for using FixYa

External hard drive read only on my mac?


That's a very strange occurrence, I agree with you. The good news is that one of the standard administrative applications included with Mac OS X will doubtless fix what's happened on your disk, which is that a folder permission has somehow been messed up.
The program you need is Disk Utility and you can find it in Applications --> Utilities --> Disk Utility. Then simply select the drive you want to fix:

You better check with the Seagate people. This seems to be a problem with the casing. And since you're under warranty, you can get a replacement.

Turn off your computer and then plug in the FreeAgent external drive. Then try turning your computer on, it should read.  If it doesn't I would go to the Seagate website for troubleshooting.
