Are there any risks for renaming files on hard disks?
There really are not many risks. There are only two risks I can think of:
- If using an advanced program or the system shell (like command prompt on Windows) one might accidentally remove or change the file extension, which tells Windows and Mac systems what to do with the file. So if "Document1.doc" is renamed to "My Document" it will become unrecognized data. To use the file, the .doc will need to be replaced ("My Document.doc"). However, there is not permanent harm if this happens, and most GUI operating systems hide the file extension altogether.
- If a storage device is failing, and you go on a renaming spree, you could in theory, cause portions of the drive to fail making data irretrievable. However, the drive would need to be in very bad shape, any you would need to rename an awful lot of files. In my opinion, this is not even a consideration.
What command is used to prepare a hard drive for first use?
FDISK allows you to establish one or more partitions on the hard drive, so the drive will be ready to accept an operating system.
Do all computers contain a removable hard drive?
From the point of view of construction, yes. At some point the hard drive had to be put in the machine and integrated into the system. It's a separate component of computers. Whether or not that means it can be removed and replaced is another matter, and the techie who looks at your machine may or may not be able to R & R the unit. Certainly as a user you'll have to weigh your skills and abilities against the difficulties associated with removing the drive yourself. If the consideration is one based on "portability" of data, grab an "add-on" or external hard drive to store data you need to truck from point A to point B. It only takes a small application (software package) on a given machine to get the external drive to work with that PC. These portable units are getting cheaper and more robust every year - or every 18 months, if you believe Moore's law (as it's stretched to apply to hard drive capacity as opposed to semiconductor density, which it originally addressed). The "remove-ability" of the hard drive says nothing at all about software considerations. Far and away the most common residence of the operating system (OS) in a computer is the hard drive. No hard drive, no OS - and there's no way your machine can come up and run.
Where can one purchase a network external hard drive?
External hard drives for Mac can be found for a low price at Amazon. They have excellent reviews and for a cheap and low price that anyone can afford.
What are basic and dynamic disks?
Basic disks use normal partition tables supported by MS-DOS and all Windows versions. A basic disk contains basic volumes, such as primary partitions, extended partitions, and logical drives. If you have any volume sets, stripe sets, mirror sets, or stripe sets with parity, you must back them up and delete or convert them to dynamic disks before you install Windows XP Professional. A basic or dynamic disk can contain any combination of FAT16, FAT32, or NTFS partitions or volumes. The disadvantage of a basic disk is that you are limited to creating only four primary partitions per disk or three primary partitions and one extended partition with logical drives. Windows NT based systems can support striping and software RAID sets for basic disks but Windows 2000/XP/2003 do not.
Dynamic disks are supported in Windows XP Professional, Windows 2000 and Windows Server 2003. Dynamic disks do not use partitions or logical drives. Dynamic disks were first introduced with Windows 2000. With dynamic disks you can create volumes that span multiple disks such as spanned and striped volumes, and you can also create fault tolerant volumes such as mirrored volumes and RAID 5 volumes. Dynamic disks offer greater flexibility for volume management because they use a database to track information about dynamic volumes on the disk and about other dynamic disks in the computer. Windows Server 2003 can repair a corrupted database on one dynamic disk by using the database on another dynamic disk. With dynamic storage, you can perform disk and volume management without restarting Windows.
Dynamic disks are not supported on laptop computers or on computers with Windows XP Home Edition installed. The number of volumes that you can create on a dynamic hard disk is only limited by the amount of free space available. Windows XP Pro, Home or 64 Bit Edition does not support mirrored or RAID5 volumes.
You can use both basic and dynamic disks on the same computer system.
Adding external protrusions to a wing would be useful but what could be one drawback?
the air molecules would not flow easily around object
Is there a way to wipe a computer hard-drive without destroying programs or program data?
The 'format' command will appear to erase the hard-drive HOWEVER - ALL it does is erase the reference track. The data will still be on the drive (and can be recovered). There are programs that will physically write either random characters or just zeros to every sector of the drive - over-writing all the data that was stored.

How many films can a 1 tb external hard drive hold?
It all depend on the length of the film and the format which is used.
A typical film in "VOB" will be 4Gb, whereas in AVI it can be 700mb.
Using a non compressed format of 4Gb per film, you will be able to get around 256 films on a 1 tb disk.
Where do deleted files go when they are permanently deleted from the recycle bin on the Macintosh?
They don't go anywhere, they are still on your hard disk (or fragments of them). When a file is deleted, some or all parts of it are still retrievable in Microsoft Windows. The subject of much anger amongst users who value privacy and security, including me. Go here for more information... http://www.microsuck.com/content/ms-hidden-files.shtml You'll find out all sorts of frightening things about the ubiquitous Windows operating system. It's a real eye-opener. Even if a file is deleted properly, it can still be retrieved using specialist software. Forensic and data recovery specialists are used by large corporations, governments and law enforcement agencies to retrieve valuable data lost by human error, physical disaster, or mechanical failure. So-called deleted files are really not deleted. The pointer to the file's blocks on the hard drive is added to the free-space list in the file directory, and this space, ''may'', eventually, be re-used for new files. Note the "eventually" part: forensic tools can easily recover deleted files with little or no damage. And you thought they were really gone. Nope. There are programs you can use to securely delete specific files or the free space on your hard, such as * Eraser, * BCWipe (http://www.tucows.com/preview/195710.html), * PGP, * Norton Utilities' WipeInfo, or * Cerberus System's Document Security Manager (See http://www.cerberussystems.com/INFOSEC/products/docusec.htm, especially ). Make sure to empty the Recycle Bin first before running these utilities. Oh, and don't forget the '''swap file'''...full images of anything you have run or viewed may still be in the Windows swap file. You need to securely clean that, too. Cerberus has a good tutorial on that: http://www.cerberussystems.com/INFOSEC/tutorial/leaks.htm
No, a hard drive is "permanent" or non-volitile data storage. It is designed to retain data after it is turned off. RAM (random access memory) is used by the processor for quick but temporary access to data or code. It is cleared when the power is shut down.
How does a flash drive retain memory?
i want to know the programming details about(how does flash memory store the data received) and the tracks that the date move in. it would be great if u could get some pics 4 that..... thanx a lot
How much data can 1TB hard drive hold?
It is obvious that 1 TB(Tera Byte) = 1024 GB (Giga Byte)
so 1TB is larger and has double more space than 500 GB.
It may be noted that 1 bit is 0 or 1
8 bits = 1 byte
1024 Bytes = 1 KB
1024 KB (Kilo byte) = 1 MB(Mega Byte)
1024 MB (Mega Byte) = 1 GB
1024 GB = 1 TB(Tera Byte)

What can you do about a fragmented drive?
A fragmented drive results in slow read and write operations as the files are scattered all over the hard disk. Microsoft Windows provides defragmenter utility to defragment the hard drive. Go to Start --> Programs --> Accessories --> System Tools --> Defragmenter
You need a CD-ROM because then you can acess its read only memory
How much hard disk space does windows xp use?
The Capacity is not dictated by the software, but more along the lines of your hardware. Windows is capable of storing up to 26 drives with Letters A-Z but usually 3 of those letters is in use by Peripherals such as CD drives and Burners along with floppy drives or removable media. Hypothetically you should be able to store numerous terrabytes of information. There really is no set limit that I know of.

What are 6 common storage devices?
There are many storage devices that are used in everyday computing. If you mean storage devices as for what you can use to store data and save then I believe the following are very common:
* Hard drive * DVD * CD * USB Thumb Drive * Compact Flash Drive (the small flash drives you put in camera's) * Network Storage Server (If you save files online this is what is used) RAM is another storage device but it is only used by the operating system on your computer. So you really have no ability to save information on them.
Where do you connector the red edge of 40-pin ribbon cable to an IDE hard drive?
The red edge of a 40-pin ribbon cable is connected to pin one on the IDE hard drive. If you fail to do so correctly, it may result in the hard drive being completely unable to communicate with your system.
Is it cheap tobuy parts of a PC and assemble or buying a complete assembled PC nowadays?
It is much cheaper to buy parts and build it yourself. Plus you choose the parts that you want, not the manufacturer.
What hard disk interface that can support up to eight or fifteen peripheral devices?
SCSI interface would be what you're looking for.
What is the most important reason PATA connectors are present?
The most important reason the PATA connector is present is the PATA connector can be used for EIDE drives such as a CD or DVD drive.
Permanent storage locstion for a set of instructions the computer uses when turned on?
I would like to tell you that ROM stores the programs that are executed when the computer is switched on. It has a program thatactvates RAM and RAM starts its work. Its work is to take small and important information about the software that is running or the operating system to be loaded. Hope you understanded what you wanted.
