    My drive has also crashed, however it can't even be read as an external drive. This is actually the second Seagate drive that's crashed. Is it just bad drives or is there something else in the PC that can be causing the drive to crash?

If your PC can detect the harddrive as an external drive there is a possibility to recover your files. try using stellar-phoenix, download it at, register first then you can use their search facility to browse files. I am using stellar-phoenix for a long time, it works well. Good luck

I've bought a hard drive to put music on for my car and every time I plug my seagate hard drive in its says error 23. Never had any problems with usb sticks.

Is it a portable External drive ?
If it is the type with a 2.5" spinning disc in it, I would not use that in a car if you paid me a fortune.
They can withstand large shock when they are not 'running'
However when 'running', even a small bump (or bump in the road), can allow the floating heads to hit the surface of the spinning drive platters, and it may never work again.
One alternative is to -
Get a portable SSD (Solid State Drive), as they have no moving parts, and should let you drive over footpaths, when running.
Or use a USB stick like you used to.
Hope this helps,

Is ther anythng I shud be worried about if my pc fell off the top shelf and is stil working properly

Check to see if your pc has a SSD drive (Solid state Drive).
If it does and it still works.... you should be good.
Reason: SSD units have no moving parts.

Non-SSD drives have spinning platters.
Any hard drives listing rpm's (Rotations per minute) spin at high speeds. Example: 7200 rpm's
A drop like that could cause the heads to crash into these platters.
Just watch to see if data starts to disappear or the pc acts really slow. The good news, most hard drives with rpm listing made recently park the heads to prevent damage from drops or sudden bumps.
Good luck and hope this helps

Dropped my portable WD Passport, now Windows won't recognize the hard drive

Suggest you remove the harddrive inside the case of the WD Passport, and install it in an inexpensive external enclosure.

However if the harddrive was on, and in use when dropped, you need not bother.

Inside that plastic case of the WD Passport, is a regular harddrive. There is also a small circuit board.
Interface Board.
The harddrive connects to the small circuit board directly, or there are cables (Wires) that come from the circuit board, and connect to the harddrive.

This Interface Board is damaged very easily.

Harddrives are measured by their Width. How wide across is it.
A laptop size harddrive is 2.5 inches across in width. (6.4cm)
A desktop harddrive is 3.5 inches across in width. (8.9cm)

There are two styles usually used in an external harddrive.

The harddrive in the WD Passport 250GB external harddrive is a 2.5 SATA harddrive.

This is an example of a 2.5 SATA external enclosure,

Why do I state forget about repairing if the WD Passport was on when dropped?
The resulting internal damage.

Bear with me, I'll try to make this short;

A) Inside the case of a harddrive as used in the WD Passport, are Platters.
These resemble a CD or DVD disk.
Usually made of metal, or glass.

The top surface, and bottom surface is coated with a magnetic medium.
(Ferrous substance)
There are usually 3 to 6 Platters.

B) There is a Read/Write Head for the Top, and Bottom of every Platter inside the harddrive.
One on top, one on bottom.

The names imply just what the portion of the Read/Write Head does.
The Read portion reads whats on the Platter. The Write portion writes to the Platter
(When writing the magnetic medium is arranged. Arranged in 0's and 1's.
1 being ON, 0 being OFF. This is changed into computer language)

C) There is an Actuator Arm for every Platter. Holds the top Read/Write Head, and the bottom Read/Write Head.

The Actuator Arms are moved back, and forth across the Platters.
The Actuator Motor moves them.
(When the harddrive is operating, the arms can move back, and forth across the Platters, at
Hundreds of Times a Second)

D) There is a Spindle Motor that spins a Spindle. The Spindle goes up through the center of the Platters.

The Read/Write Heads are parked away from the Platters when the harddrive is not activated.
When activated the Read/Write Heads have a VERY close proximity to the surface of the Platters.

If memory serves it's around .0003
Three ten-thousandths of an inch.
An average human hair is .003
Three thousandths of an inch.

With the close proximity of the Read/Write Heads to the Platters, and the extremely fast movement, the Read/Write Heads actually float on a cushion of air.

If dropped while activated, the Read/Write Heads will crash into the Platters.
Retrieving information, would require a professional data retrieval shop to remove each Platter, and install them one at a time in a harddrive setup they have.

As much information is retrieved as possible.
Once a harddrive is opened up, it is doomed. A harddrive is built in a Clean Room.
A room that is 99.9 percent dust free. The tech's wear a suit, and have to walk through a corridor with air jets, before they can enter the Clean Room.

For additional questions please post in a Comment.

Dropped laptop-IBM Thinkpad X21-display now reads "A disc read error occured" "Press ctrl-alt-del to restart" Bios is accessible but I am a novice in that area.

I don't think going into the BIOS Setup utility is going to help.

If the laptop was on when dropped, one or more of the Read/Write heads probably crashed right into the Platter/s.

To expound:

Inside the Harddrive case are Platters. These resemble CD disks, but are made of metal, or glass.
On the top, and bottom of the Platters a magnetic media is applied. Usually a Ferrite compound. (Read Iron)
There may be 3 to 6 Platters.

EACH Platter has a Read/Write head Above it, and Below it.
The Read/Write head does just what the name applies. Reads from the Platter, and Writes to the Platter.

[The magnetic media is arranged around the Platter, very similar to how information is arranged around on a CD, or DVD disk.
It is arranged in Circles, (Tracks), and segments within the Circle (Sectors)

The magnetic media is arranged by the Read/Write head, (Write portion actually), into a series of 1's, and 0's.
1 being ON, 0 being OFF.
The 0's and 1's are converted into machine language for the computer ]

The Read/Write heads are moved back, and forth across the Platters by an Actuator Arm.
When the computer is in use, (Computer using a program for example), the Read/Write heads can move back, and forth across the Platters at Hundreds of times a Second.

The Read/Write heads are in a stationary position away from the Platters, when the computer is not on.
When the computer is on, the Read/Write heads are positioned above, and below the Platters.
They are positioned VERY close to the Platters.

(So close, that that the movement when using the computer, actually has the Read/Write heads floating on a cushion of air)

Computer on, and dropping it can cause one, or more Read/Write heads to actually crash into the Platters, and wipe some of the magnetic media OFF.

This would mean replacing the Harddrive, AND having the Restoration Disk, (CD. Also may be known as System Restore disk, or Restore Disk)

No Restoration Disk means buying a new, fresh, genuine copy of Windows, and installing it, on the new Harddrive.

On the Platters in one of the sectors, is the Boot Sector for your Windows operating system.
It could be that when the Read/Write head/s crashed on the Platter/s, that part of the Boot Sector was wiped.

It could be by a slight chance that the Harddrive has come loose. Pulled away from the interface in the laptop that it is plugged into. THAT would be a stroke of luck, but advise do not get your hopes up.


2) IBM ThinkPad X21 Service Manual (Free)

Click on X20. This manual covers the X20, X21, X22, X23, and X24 models.

This is a PDF file. Allow a few seconds for the first page to come up, and additional time for the file to fully download. Let the file download all the way before looking through it.
There is a way to save a copy to your computer you are using now, and burn it off to CD disk, if you wish.
If you do not know how, please post in a Comment, and I will tell you.

I hear click sound when open.

The arm that moves the heads over the platters inside your drive is loose. That means your drive is mostly toast. Read this link that I wrote on hard drive failures. It also has a way you can possibly recover a few files.

In mycomputer if i connect 40 gb hard disk. it is not working. if i connect another hard disk it is working. how to fix that defective hard disk

a single speck of dust is bigger than the gap between the platters and read/write heads. If dust/debris does enter the drive, it can have catastrophic results when the heads crash into it. SO OPEN your hard drive's sealed casing to clean the hard drive. clean it and fix it .

YES it sounds just like that what should or can I do to fix my hard drive???

Just a note, instead of making another post, you can just reply to it and I will get back to you just as fast. Well, sorry to say, but you can't do anything to fix it yourself. The problem (sorry if you don't understand) is apparently the fact that the read/write heads for some reason don't park themselves off the platter when you turn your computer off. This causes the read/write heads to stick to the platter, and the platter cannot spin. If you have a warranty, you could sent it back, but if it has expired, then there is nothing you can do except get a new hard drive, and don't get Maxtor next time, instead get a more reliable brand like Seagate.
