Security – How are pseudorandom and truly random numbers different and why does it matter?

DATARECOVERYUNION.COM3 years ago3 years ago032 mins

I’ve never quite got this. Just say you write a small program in any language at all which rolls some dice (just using dice as an example). After 600,000 rolls, each number would have been rolled around 100,000 times, which is what I’d expect. Why are there websites dedicated to ‘true randomness’? Surely, given the…

Tips for WD Data Recovery

DATARECOVERYUNION.COM13 years ago4 years ago03 mins

WD Drive Data Recovery
If the drive is spinning and shows up in Disk Management (Windows), or Disk Utilities (Mac), but you can’t access it, then the drive’s partition table may be damaged or corrupted. It may be possible to still extract the data utilizing data recovery software. Western Digital does not provide data recovery software, however, there are several kinds on the Market. If you do a web search for Data Recovery it will yield plenty of data recovery software options.

If the drive does not show up in Disk Management (Windows), or Disk Utilities (Mac), and you have tried all the troubleshooting options relevant to your drive, then your drive has most likely failed and you will need to contact a data recovery company to retrieve your data.

Western Digital does not provide data recovery services. However, They have a list of recommended preferred data recovery partners that you can use for data recovery services.

WD Drive Circuit Board
Western Digital does not sell or replace circuit boards for our hard drives nor are we aware of any other companies that sell them. Replacing the circuit board on a hard drive is not a recommended method for recovering data or drive functions as this will void the warranty on the hard drive. For every hard drive model that Western Digital manufacturers, there are many firmware changes that would make it very difficult to find a circuit board with the same firmware of the defective drive. If you attempt to install a circuit board with a different firmware than the original, this may damage the hard drive further. HDDZone.com is a recommended shop which can helps to find a matching western digital pcb for your dead drive.

WD Drive Repair
Western Digital does not repair or recommend repair services for our drives. Any repair services performed on a WD drive will void the warranty. If your drive is under warranty, please see How can I replace a product under warranty?

How do I determine what type of hard drive you have?

DATARECOVERYUNION.COM15 years ago7 years ago04 mins

The following methods can help determine what kind of hard disk you have inside your computer.

1. Seatools For Windows

Seatools for Windows can detect all hard drives connected to your computer.

2. Device Manager

a) Users running Microsoft 2000, XP, or Vista

Microsoft Windows users can easily determine the type of hard drive that is currently installed in their computer by following the below steps.

Right click on “My Computer”.
Select “Manage”.
Click on “Device Manager” in the list on the left.
Select the “Disk Drives” entry.

Note: This will not show the serial number of the drive, just the model number.

b) Users running Apple’s Mac OS X

Follow these steps to open Disk Utility.

Open a Finder window
Open “Applications” (if necessary).
Open “Utilities”.
Once Disk Utility is open, it will show all of the connected hard drives on the left. It will show capacity and model number.

c) IBM-compatible users

Users of IBM-compatible machines can usually enter the computer’s CMOS to view additional information about their hard disk drive. Commonly, the CMOS will list the drive’s serial number and/or model number, cylinders, heads, sectors, and/or the size of the drive.

If the CMOS is not configured to auto-detect the drive, it is important to note that the drive values may not be correct. All modern drives should be set for automatic detection.

3. Disk utilities

Many disk utilities designed to setup the hard disk drive will properly detect and setup a drive; in addition, they may also provide the user with some basic additional information about the drive.

For example, using the FDISK utility, you can display additional information about the size of the hard drive and partition information.

4. Other methods of determining the type of hard disk drive

One of the best methods for determining additional information about a hard drive is to check the sticker or label on the drive’s top. The majority of hard drive labels will list not only the RPM of the hard drive but other useful information, usually including the model, kit, serial, and/or part number(s). Turn off the computer and physically open it to see if this information is visible on the drive label. If you are unable to locate the information you need through software, it is recommended you open the case and remove the drive to get the information you need.

Determining the speed or RPM of a hard disk drive

To determine the speed or RPM of a hard drive, you must first determine the manufacturer and model of the drive. Once you’ve determined this information, you can lookup the drive on the manufacturer’s website to determine its RPM.
