Removing HDD Partition Without Reformatting

DATARECOVERYUNION.COM01 mins

I have Windows 7 Ultimate 64 bit and Im gonna get an extra hard disk, question is can I delete my partition on the old hard disk without reformatting so that I can make that whole drive for programs and the new hard disk for storage?

There are programs that are supposed to be able to do this like partition magic. What you want to do is format the new data drive and backup all your important files to it. Once you have your back up safe, go ahead and run your partition program. They *SHOULD* work, but in case it doesn’t you have your files safe. I don’t know of any free ones, try a google search.

WD Data RecoveryWD 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?

Platter Scratch Repairing

Hard Disk Drive Crash
Take the case of computer systems. We become so used to working on the computer on a regular basis that we are rarely ready to face the consequences if things go wrong. This is truer of a computer hard disk drive crash than of anything else. Hard drive malfunction can be divided into two types: one is the so called Firmware Level malfunction that can be repaired using relating software or factory commands; the other one left is the Physical Level malfunction caused by physical hard drive components damage. As to the latter Physical Level crash, the typical case in data recovery practices is that the head crash and serious platter scratches caused by direct contact between the head and the platter surface; such drives manifest themselves as undetected, staying BUSY, besides an ominous scratching sound may start to emanate from the disk. This is a serious problem. It is indicative of nothing less than a crash of the hard disk drive.

Functioning of a Hard Disk Drive
In order to understand the problem of a hard disk drive crash, it is important to first understand the mechanism of a hard drive. Only after knowing how the disk drive functions can one understand the nature of the problem.

Components
Read-Write Head: The read-write heads of the hard disk drives are those mechanisms that, as the name suggests read or write the data from the magnetic fields of the platters.

Hard Disk Platter: A hard disk platter is a circular disk within the hard disk drive. It is circular in shape and the magnetic media of the disk drive is stored on it. Generally multiple platters are mounted on a single spindle of the hard disk drive.

Lubricant Layer: This is the topmost layer of the platters and is made of a substance similar to Teflon. Carbon: There is a layer of sputtered carbon just below the lubricant layer. Magnetic Layer: This is below the layer of carbon.

Functioning
The magnetic layer of the hard disk drive stores all the data. The two layers of carbon and the lubricant like material saves this magnetic layer from coming into accidental contact with the read-write head of the disk, we can say they exist as the protection layer of the magnetic layer (of course, another important function of them is to maintain the stability of the flying read-write head)
