Portable Harddrive - Works on Newish Lappy, not on old Thinkpad

Got a portable harddrive, PCMIA card USB 2.0 adaptor and the power lead for pcmia card. Drive has enough power, but is not recognised in my computer (running XP). The drive works fine on my desktop and my 3 yr old laptop. The laptop I am trying it on is a IBM Thinkpad X20 - 2001 I think. It only has 64 RAM, waiting on a 256 RAM stick to arrive if that will help.

About 2 months ago I bought a samsung s2 portable 1Tb. It has worked fine until yesterday. It slipped down from where it was laying (while plugged in and running) and was hanging the 20 cm usb-cabel. Now I...


Hanging by the 20cm USB cable?

The cable could be stretched, and wires broken inside.
The cable to small circuit board, inside the case, could have broken solder joints.
The circuit board inside the Samsung's case could be broken.

Inside that small outer case of the Samsung portable is a laptop size Harddrive.
The harddrive measures 2.5 inches across in width.

(6.4cm. In comparison a desktop size harddrive is 3.5 inches across in width, or 8.9cm)

The harddrive is a SATA unit also.

This is a general example of a 2.5 SATA harddrive,

http://www.newegg.com/Product/Product.aspx?Item=N82E16822148591


Inside the outer case (External Enclosure) is also a small circuit board (PCB)
The harddrive plugs into the small circuit board, and the circuit board has a USB cable attached to it.

(Or there is a small cable from circuit board to harddrive. Then a USB cable to the circuit board)


I would suggest removing the 2.5 SATA harddrive, and install it into an economical external enclosure.

Example of a 2.5 SATA External Enclosure,

Basic guidance in removing the Harddrive from a Samsung S2 Portable,

1) It looks as though the outside front is a thick cover like a label. It may be that you peel back the corners, and there will be a screw in each corner.

(For example; Where it states Samsung. Go to the right corner. Does this cover-like material peel back? Is there a screw underneath? Remove it.
Go to the opposite corner. Now above to the left and right corners)

The unit looks to come apart in two halves.

Might just be held together by sticky tape.

Here are some videos performing opening the external enclosure, (Case) of other external portable harddrives,

There are other related videos. In general most are not very professional, but get the job done.

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.

Why can't I access anything that was copied onto my Toshiba 500G external harddrive. The computer doesn't recognize the program that made any of it, even though it's the same computer.


It is very possible the voltage on your computer's USB port is not handling the load. I would buy a "powered" USB 2.0 hub, plug it into your computer's usb port and plug the harddrive into the powered hub.

After a time, Computer not recognizing portable harddrive


Reformatting will be our last option and there are a number of steps that you can try to fix this.
  • Try plugging it in on a different USB port
  • Check the USB cable, try replacing it and see if it works
  • USB ports on your computer makes use of power, so if you have multiple USB devices plugged in, the portable hard drive might not be receiving enough power. Try plugging it in without your other USB devices, except the mouse of course

Please leave me a comment for this.

NOT WORKING OF 120GB PORTABLE HARDDRIVE


I think you are using an 2.5" notebook hard disk drive into this external case which hasn't got an extra power supply.

Since you're using an USB1.1 connection this could be a USB1.1 issue, USB2 returns more power to the connected device, since you connected you harddrive too an USB1.1 port you might need an USB cable which you can plug into 2 USB ports.

By doing this one USB port will provide the power to spin the drive up (which needs a lot of power) and the other cable will be able to focus on the data transfer.

You can also check your disk manager, it could be the drive is requesting a drive letter that's aready in use by another device. Go to start -> right mouse click on My Computer -> manage -> storage -> disk management. If the device is within this list you might attach another drive letter to it by doing the following. Right mouse click on the disk -> Change drive letter and paths and there you change the current drive letter into another one.
