Re: 2100: Detection error on HDD0 (Main HDD)

It is telling you that there is a problem with your hard drive. If you know how to get to your bios screen and have a recovery CD you should be able to restore it. That is IF the hard drive is in fact not defective. Otherwise you will need to to take it to someone who does computer repair and either let them replace the hard drive or depending on your ability do so yourself or purchase another laptop

How to fix error 2100: hdd0

The ThinkPad system may experience a bluescreen that may only appear for a very short time, followed by a reboot. During POST, the system will display a POST 2100 error code indicating the drive cannot be initialized. The machine will not boot into the operating system.
NOTE: Powering the system fully off and then on again after 20-30 seconds will usually clear the error, but a warm reboot will not.
IT have personally experienced this issue twice so far, & Lenovo posted an advisory on this in July.
If you have encounter this issue since getting your T440 notebook, it's highly recommended to update your SSD to this new firmware.
The firmware updater is windows based, & is non-destructive (does not affect existing data) so it's easy to update.
To be absolutely safe though, it's recommended to back up your essential data before installing this firmware update.

Also recommended is to use CCleaner registry cleaner which solves the problem temporarily.

Hard drive not working..unable to boot up. Get this error message : 2100: Detection error on HDD0 (Main HDD) Press Esc to continue

Please try re-seating the hard drive.

If you look at the bottom of your laptop, along the edge there should be a screw larger then all the rest which holds a small panel. Remove this screw and panel. Remove the drive pulling lightly, with steady pressure, straight out. Place the drive back in and screw the panel back.

We had a lot of these issues, and they were often solved by just this manner alone.

Let us know if we have to go any further.
Good luck

I can't boot up. it display error 2100: Hard disk drive initialzation error.

This issue is often caused by either an incorrect setting in BIOS or a bad boot device, such as a bad hard disk drive.

Try this:

Verify that your hard disk drive is setup and detected properly in BIOS. You're computer should list a hard disk drive installed either under the main page or the drives page in BIOS. If BIOS indicates the drive is not installed or not detected skip to Hard Disk drive is bad or not connected properly.
Verify the boot options are properly set in BIOS, almost all BIOS setups should contain options specifying how your computer boots. For example, most computers should have their boot options setup similar to the below example.

- Floppy drive
- CD drive
- Hard drive

Rest your BIOS to default values. Many BIOS will enable users to reset the values to the default settings. If you've tried the above options without success try resetting the BIOS.

Boot from either your emergency repair disk, your bootable Windows CD, or your bootable restore CD.
Once boot attempt to repair Windows. If you're able to repair Windows remove the disks and reboot the computer.

If the above fails:

Verify the connections are properly connected to the computer if the hard drive was recently installed or the computer was moved.

If all connections are setup properly and all the above recommendations have been attempted, it is likely that the hard disk drive is bad and it will need to be replaced.

Let us know how it works out.

When i am told to insert disk and reboot..and press and hold f12 or wont boot off the goes to windows start up

Most likely because the array in the bios is set to look at HDD0 which is your hard drive first. If the hard drive has and executable file for loading an operating system and the array is set that way it will not look at your CDROM for a boot file. So look up the F key command on google for whatever model laptop u have to get into the bios. Once your in there you need to change the array to look at your cdrom 1st before HDD0.

My XP will not boot when my Hitachi 1TB External USB 2.0 drive is connected. It gets as far as showing the Pentium screen and stalls.

Its probably trying to boot from your external drive.

Go into your bios and reset your boot setting to HDD0 as your first boot device, Disk drive 0 second and floppy third, unless you want to boot from an external drive. That being the case select an appropriate order.

If the bios shows your external HDD as HDD0, then you have to work out which is the drive carrying the operating system and set that to your first boot device.

To get into the bios, watch the boot screen for a key to hit to enter setup, normally its the "DEL" key.

My ibm thinkpad r51 is not starting up just keeping giving me error message and it doesn't recognize the hard drive in boot. I have to take the battery to stop the system trying restart the window again...

It appears the hard drive is faulty.
Does the hard disk LED flash when the laptop boots up?
Go into the BIOS configuration and see it the hard drive is detected, (then Startup - Boot - and look at IDE HDD0 it should list the make and model of the hard drive).
If the hard disk is detected it still could be faulty. To test the hard drive, remove the hard drive and connect it to an USB hard drive adapter and connect it to a working computer's USB port.
If the computer sees this as an external hard drive and you can open the various folders and files then the hard drive is OK and the fault could be the disk controller on the laptop's motherboard.
If the hard disk is not detected the it is faulty and you need to replace the hard drive in the laptop and install Windows etc. to get it working again.
