Hard Disk Drives

Foreign drive

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.

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.

Hard disk drives

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

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)

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

External drive bays

You need a CD-ROM because then you can acess its read only memory

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.

can anyone help me????????

my pendrive is asking me to remove write protection

i tried making reg values to 0 but no0 use, i downloded a usb format tool but that doesnt wrk at all

any body help me plse.........................

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.

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.

It is much cheaper to buy parts and build it yourself. Plus you choose the parts that you want, not the manufacturer.

SCSI interface would be what you're looking for.

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.

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.

Let's see:

Harddrive

Solid State Memory (RAM)

Optical (DVD / CD / Etc)

Memory Cards? (SD Memory / CF Memory / Etc)

Technically the last would be the same as RAM, but it isn't used the same. RAM is used in most computers as temporary memory. This memory only retains information while power is provided to it. Once the power is removed then it loses everything. With a memory card type of memory such as NAND type of memory, information stored in the memory card is retained even when the power is removed (USB memory sticks / SD memory / etc).

The best and most trusted back up would be to do it yourself onto discs or external hard drive. Symantec is a very good data solutions company with a good reputation.

The drive interface that uses an 80-conductor ribbon cable is IDE. IDE stands for Integrated Drive Electronics, an interface commonly used to connect hard disks and optical drives to computers.

Because alternative media won't boot with alternative operating systems.

Read only memory (ROM)

You remove the hdd from the laptop, write down the model number, phone your IT supplier but an identical hdd and fit it to your T41. Then recover using the recovery disk. Your old password'ed hdd is good to use as a paperweight.

Look at the front of the machine beside the activity LEDs. You'll see a panel. Turn the machine over and unscrew the panel, theres only one screw holding it on. Now, it takes some working to actually get this cover off, but it will come off eventualy. Inside there you'll find the harddrive, its just a simple matter of unscrewing it and pulling the cradle out.Refitting is the reverse of removal.
