Hard Disk Drives

Hard disk is more popular than floppy disk because hard disk can store huge amount of data in term of mega byte to giga byte. It stores the data safely compared to floppy disk. External hard disk are portable so they can transfer the data from one computer to another . But floppy disk has low capacity and are vey slow compared to hard disk . It can be easily damaged when exposed to heat and dust. Files can be easily corrupted and data transfer rate is slow compared to hard disk. Nowadays, computer are built without floppy drives which is needed to read floppy disks.

No, that is why many people are complaining. You have to buy an external hardrive. (seperate)The best deal you can get is the sony PS Vita starter kit on playstation.com (it retails 34~ish dollars on amazon)

Depending on the model you are using, it depends on what you mean.

Typically, most models have primary storage as the Hard Drive (or now, Solid State drive may be as well), a type of nonvolatile storage whose data does not disappear if it is unplugged or loses power.

Secondary storage usually refers to things such as CDs, DVDs, Floppy, Zip, and Tape drives. However in some textbooks it may just mean a second HDD/SSD.

Tertiary storage pretty strictly refers to CDs, DVDs, etc.

Deleting or formatting won't make the data in memory card erased permanently.

Those deleted data is still stored on the memory card, it's just invisible or inaccessible. Only the FAT or NFTS table is erased (the information about where those data were saved), but the real data are still intact there in sectors of the hard drive.

So as long as those data are not overwritten by new data, it's highly possible to recover them. And the MOST Effective way is to rely on some format recovery programs.

Note: before the data is recovered, never attempt to put more files to the disk. As saving more files may cause original data overwritten. Once overwritten, it's impossible to recover the lost items.

it's either:

seek time,

computer virus,

data transfer rate,

rotational delay,

setting time,

magnetism,

Due to limitations imposed by DOS back in the '80s, ATA (the proper name for ide) and SATA drives can only hold 4 partitions. To work around this, extended partitions were invented. Extended partitions can hold 4 more partitions, any of which can be more extended partitions. Thus the number of partitions is effectively limited by the size of the disk. These limitations aren't imposed by the disk itself, rather the PC architecture. Intel macs, which don't need to maintain compatibility with DOS or old versions of windows use EFI, which allows for 128 primary partitions.

In the current market, there are usb hard drives that have a storage capacity of up to six terabytes (TB) of storage. In the future, it is possible that newer technology may surpass the storage capabilities of the present.

A read/write ____ is the mechanism that reads and writes items in the drive as it barely touches the disk's recording surface

If you are losing disk space constantly for no good reason, then you have a old type virus that a simple anti-virus scan will detect and remove Music and Video can chew up memory like nobody's business. Those files should be sorted through and non-used files deleted. The next big culprit is how your computer is saving files. If you haven't run a disk defragmenter before, now is the time. On a Window's based operating system, select Start Menu > Search > Files and Folders > type in "defrag". Then, when you see "Disk Defrafmenter" appear in the search terms, select it. Click on the "Analyze Disk" feature and in a minute you'll have a picture of how messy your disk drive is. Likely, your computer will reccommend that you proceed with the Defragmentation and you should start this process. The whole process should take 30-90 minutes. Upon completion, you should see a vast improvement in performance!

40 gigabytes=

40,000 megabytes=

40,000,000 kilobytes

They are terms used for how much data you can store on an item. One well known item is a camera.

GB= gigabytes

Yes it is removable media. It can store all sorts of data, but can you remove it while the computer is still on? Yes, removable media is a part of a computer that can be removed while the computer is still running.

It depends on how large the flash drive is, and how large the files are.

Take the size of the flash drive in GB, divide by the average size of the files in MB, and multiply by 1000.

So for example if you are storing photographs that are 2 MB in size on an 8 GB flash drive, you could store approximately 8 / 2 x 1000 = 4000 photos

==========

It also depends on the file structure in use. Most flash drives come pre-formatted with either FAT32 or exFAT - although most of them can be re-formatted to use other file structures. Both FAT32 and exFAT allow some flexibility in the size of the clusters used. Since storage is allocated by cluster - with enough clusters allocated to accommodate each file, the maximum number of files is also limited to the number of clusters.

As an example, theoretically if you had an 8 TB flash drive (wouldn't that be sweet) formatted with FAT32 using 32 KB clusters the maximum number of files would be 268,173,300. For smaller total capacity and/or larger cluster size, the number of files will diminish proportionately.

A normal delete does not actually delete a file, it just marks the hard drive space as available for later use. All the data are still there, and there are software programs that can bring it back more or less intact.

Even after a real deletion, or after the disk is reformatted, traces of magnetism remain on the hard drive, and with special equipment it is possible to read those traces and reconstruct what was there before deletion. This is true even after the deleted content has been overwritten once or twice.

It is not only FBI that can read deleted files, there are commercial companies that offer similar services, for example to businesses that accidentally reformatted the hard drive containing all their customer data.

Some programs offer a "safe delete" option which overwrites deleted files 20-30 times with random noise, to make sure that the data are really gone. This is now the standard option for emptying the waste basket in Mac OS X, for instance.

The drawback of "safe delete" is that it is much slower, especially if you delete a lot of data. And of course it means that even the companies that specialize in retrieving deleted data cannot help you if you accidentally delete something you shouldn't.

Usually only one.

"What kind of hard drive..." How do you define "kind": ATA, SATA, SCSI? Or do you think of the capacity? Or manufacturer? You will get a lot of information, when installing a small tool called "AIDA32". It is freeware and can detect a lot of your hardware. Try Google for AIDA32, download and install it. You will be astonished what it has to tell you. Or just open up your system, watch closely and search on the Internet for the drive model. But I think, you don't know what to look for, otherwise you would not have asked this question ... :) AIDA is here : http://www.majorgeeks.com/download181.html Good luck.

there are 2 type of hard disk

1)internal hard disk

2)external hard disk

there are 5 kind of hard disk in each hard disk

1)ATA

2)firewire

3)SCSI

4)RAID

5)fibre channel

ya you can fix it just open the drive and back side of the laser light you will get a screw type component on the chip then take a thin screw driver and just turn a very very little bitt hat screw clock wise. if you turn it more than it need that will not be able to read a bad disks so turn just a bit just a bit get what i want to say just a bit

Temporary storage is usually referring to RAM -- Random Access Memory. Data stored in RAM only exists while the computer has power (nothing is saved).

The main thing that will determine if your computer is slow or fast is the hardware that it has. The faster the hardware the faster your overall computer speed will be (generally). The main that slows down your computer is the the operating system. If you have used Windows XP in the past and made the move over to Windows Vista you would have noticed a dramatic decrease in computer performance. The reason for this is because Vista is actually slower than XP. The main reason for this is because Vista has a lot of fancy things on in that are designed to make it look pretty which are of no use to you when it comes time to actually use the computer.

So the two main things that you have to consider are your computers hardware specifications and the operating system that you are running.

what is the difference between a file system and a database system?

A normal hard drive consists of a disc that is constantly being written and overwritten, whereas a solid state drive consists of flash memory, like a USB drive. It has no moving parts and is all in one piece, therefore, solid state.
