What are three ATA hard drive interface standards that do not use a 40-connector hard drive cable?
ATA/ATAPI -4, ATA/ATAPI -5, ATA/ATAPI -6, ATA/ATAPI -7 (SATA)
Where can one buy an external hard drive USB?
The best solution to this question is to visit your local computer store such as best buy or staples. The company will be able to help you purchase an external hard drive for your computer.
List two advantages of the SATA drive over the PATA drive?
a SATA hard drive can be connected to and controlled by a SAS hard drive controller
Can you plug sata discs into sata 2 connectors on motherboard?
Yes. You can add as many hard drives, or other sata devices (DVD burners etc) as will fit into your case, or until you have no more sata connectors free.
Is a hard copy data transmitted by email?
No, hard copy means a paper copy. e-mail transmits electronic information not paper.
How do you remove the hard drive from a Gateway M305CRV Laptop?
Shut down the laptop. Turn over the laptop and you will find a small panel with a Hard drive sign with 2 screws on the panel cover. Unscrew the cover carefully and pull out the HD very carefully. It's very simple.
Can i use an operating system on an external drive?
Yes and no. It depends on the operating system. Windows XP can be made to boot off of an external drive by following a guide at ngine.de. Linux and OS X can boot of external drives. Some machines can boot using eSATA hard drives depending on the controller used. The ngine.de guide is for USB hard drives, Linux can run on USB and Firewire, same with OS X. Vista nd Windows 7 cannot be run off of a USB or Firewire Drive, but can be run off of eSATA under the conditions from above
In what kind of machine is a floppy disk used?
The floppy disk, both the original 8 inch size and the later 5 1/4 inch size were used in all sorts of relatively early computer equipment.
- To distribute and load firmware in a model of the IBM System/360 mainframe.
- For software distribution as well as backup/restore media for the IBM System/38 and various other model midrange computer equipment.
- For software distribution and data storage on a Digital Equipment Corporation (DEC) PDP-11 system.
- For data storage and various word processing machines.
- As system devices and data storage for the original IBM Personal Computer and other similar personal computers.
Its use was replaced by the 3 1/2 inch diskette when it became available.
How do you completely wipe a hard drive with command prompt or MS DOS?
Well, there are several ways:
Getting Rid of the Data Physically and Destructively
One, if you don't need the hard drive after the "wipe," is to hammer a nail or two through the unplugged drive, rendering it unreadable to all but the most dedicated data recovery team. If you have an extremely powerful magnet, you could run that over the drive a couple times, too.
Starting Over With a Hard Drive
If you are simply trying to start over with your hard drive, you can use Windows' built-in formatter to erase and reformat the drive. In "My Computer," right-click the drive, select format, use all of the default settings (save for the label of the drive), and hit "Format." This will not work if the hard drive you are trying to wipe is your only or main hard drive, though, and is not completely secure for those of you who are trying to purge data permanently and securely.
If it is your main hard drive, then you can simply reinstall Windows or any other operating system on your computer. This is done by popping in the recovery CD's or installation CD's that most likely came with your computer. Doing this will wipe all data and start you off anew, though the nature of the reinstallation means that this method is about as secure as the previous method (read: not very secure).
Wiping Sensitive Data
One last option, for those of you who want to wipe your drive securely and do not want to reinstall Windows, is to use a third-party program to erase your hard drive for you. The technique that these programs use is to write a large file to your hard drive over and over again to get rid of any residual stored data. These programs will probably cost money, and should really only be used by those who are either selling their current hard drive, and want sensitive data off, or those who really need to remove all traces of their files. To find a program capable of this, Google "Hard Drive Eraser" or "Secure Hard Drive Delete."
One could possibly do the same thing for free by deleting all of the sensitive files by reformatting, reinstalling the OS, or just deleting them in Explorer, and then writing large files to the hard drive until it fills up. This method would rewrite all of the hard drive, and render all of the data almost completely unreadable.
I hope this was helpful. Good Luck!
In my opinion, it depends on what you use most on your computer. Most users browse the internet, so it would be the Temporary Internet Files group. Another is Recycle Bin because it has a bigger file/size capacity.
How do you make your external hard drive your main hard drive?
I think you would press F2 or some other key to enter the BIOS, Satellite Toshiba press the right arrow during boot up. Normally there is a message on the monitor saying what to do. Once in the BIOS set the boot order to boot from the USB drive, if the OS is on that drive. Some versions of Linux will boot from the CD and do not have to be installed. This is a big help if the hard drive does not work of if you just want to boot from a different OS. Linux and Wndows applications are compatible for all I have seen.
What is an organized collection of information stored in computer-readable form?
"Organized" means similar data will be grouped together on the hard drive. This can be done by de fragmenting your hard drive. This is essential because an HDD can process only so fast... if all similar information is grouped together, it knows where to find it and doesn't need to spin extra rotations to find data.
How many pictures will a 320 gb hard drive hold?
A memory card with a capacity C will hold N images approximately, where N = (C-O)/A. O is an overhead figure, accounting for storing names of pictures and maintaining the directory structures, and A is the average size per image. The overhead figure can be ignored, as it is small compared to the totol capacity C and the variation of A. The average image size is a function of the camera's resolution and the subject depicted, and can be anything between several tens of kilobytes to several tens of megabytes. The image size varies with the subject because different subjects compress differently; a photo of a plain white wall will need less storage than that of complex structures in a flower bed, for example. Assuming an average image size of 12 MB -a pretty high value only needed with slightly over-average high-resolution cameras-, one can estimate N as 160GB * 1024MB/GB / 12 MB/image = 13,653 images. For currently available commercial cameras and an average spread of subjects, it is probably safe to say that a 160GB memory part can store at least 14,000 images. Your mileage may vary though.
What are the concentric circles on the disk surface of a hard drive called?
Tracks.
The pie-shaped sections are called sectors.
Groups of sectors make up a cluster.
What are the main differences between EXT and NTFS file systems?
NTFS and EXT3/4 have completely different internal workings to do the same tasks, with the latest versions of EXT being slightly faster. The only real user-visible differences are support for them amongst Operating Systems.
NTFS is Windows native, but has full support in Linux and read only support in OSX. However Linux cannot really repair filesystem damage on an NTFS drive
EXT3/4 are Linux native, and requires a third party driver to be read on Windows.
What does the disk defragmentation utility do?
It rearranges all the parts of files on a computer so the they are all in one place. This increases the speed of a computer and is easier on the hard drive because it doesn't have to do as many seeks.
Is it possible to connect external DVD drive to any tablet PC?
It depends what kind of tablet you're using. I don't know for apple stuff but on android devices you can buy a usb adapter (or you even have a usb port). I guess then it should work!
Why is the hard drive called c?
In the old days, computers had floppy drives. They usually had two, so you could put a program disk in drive A, and a data disk in drive B.
Later computers kept two drives so they could support both formats: 5 1/4 inch, and 3 1/2 inches. By this time, hard drives were universal, and almost always installed as the C drive.
AnswerOriginally, computers used floppy drives. The first drive was called "A:", then computers had 2 drives, A and B.Then... hard drives
What are advantages and disadvantages of a hard disk drive?
Hard disk drives are a highly popular medium of computer storage because of their enormous capacity compared to other media. As a disadvantage, they are more costly and, depending on the type, have a limited lifetime.
How many movies can fit on a 2 terabyte hard drive?
Approximately 2000
(More like 200 or 100 if you rip the whole thing)
I just ripped 105 movies, and they took up 366 gigs. I only copied the main movie, and not any other features or menus on the DVDs. Also, maybe about 5 of them were only about 25-30 minutes long, while most of the rest were full length movies. This is straight ripping without compression.
How is information stored on the hard drive of your computer?
At the most basic level when a computer writes anything to any media, even going back to the old "floppy" disks, it is in bits and bytes which are simply positive and negative images electronically recorded on the physical media. Some are one time only like a CD, others can be rewritten, some information can only be accessed sequentially, others must have an index.
Hard dirves are made up of bits and bytes, sectors,files, indexes and they all inter-relate to store the information.
The disk drive head writes a magnetic pattern onto the spinning metallic disk similar (but at a much greater speed & density), to the way the old floppy disks worked. A modern disk drive has several individual disks contained in one drive, on the same spindle, and multiple heads between the disks to achieve todays mega and gigabyte capacities, and speed. The head does NOT contact the media, but actually flies above the disk, analogous to a jet flying over a runway at full speed without ever landing. A "touch and go landing" of the drive's head would permanently damage the disk.
Does a PC include a hard disk drive?
Yes, most PCs include a hard drive. Any that you buy preconfigured would. Ones that you build yourself, you would have to make sure to order that component. And really old PCs, many of them did not. They booted from disk, or had tape drives sometimes.
