Hard Disk Drives

a hard drive is hardware (stuff built into a computer). the hard drive is a disk that stores a massive amout of computer memory. my computer hold 140 gigs of memory. so in other words a hard drive is just one amazing disk.

Asked the same question myself. Positive answers, one being to clean the dust out of hard drive. So I undid the side panel, and proceeded to hoover and remove the thick dust. Was very careful not to touch anything inside the hard drive. Cleaned the motor fan, put panel back on. Switched on PC and joy of joys, a quiet running hard drive, a pleasure to be in the office now and work on computer.

1. When data is recorded onto magnetic tape, it is written in blocks with inter-block gaps between them. The rate at which data is written or read determines how the tape drives will have to cope with the rate at which data goes on and off the tape as well as the rate at which data is supplied to or demanded from the host.

Files can be transfer from one PC to the next using either by setting up network or using a removable storage device. Using a removable storage media like flash drives is the best solution where computers are not very far apart geographically.

Depends on the hard drive capacity. A typical 500GB hard drive can contain a lot of data. The typical user wouldn't fill that much space. Text documents and even pictures barely can make a dent, operating systems (such as windows vista) take about 10 gb. Hard drives have a pretty much unlimited size at this point, you could make a huge one that holds hundreds of terabytes (1000 gigabytes). a standard hard drive is around $100 and would hold between 300 and 500 gb, depending on the manufacturer and the speed of the drive, the faster you go the more expensive.

It depends on the type of file you are talking about.

If you back up your documents (Word, Excel) or photographs then you can certainly delete them from your computer hard drive once they're on the external hard drive. If you need them again you can simply plug the external hard drive to the computer in order to access them.

If you're talking about program files than you have to consider whether or not the external hard drive will always be plugged into your computer. If you move a program file and then unplug the external hard drive then you should not delete the files unless you plan on plugging the external hard drive in (or leaving it attached) every time you want to use that program. If you don't mind accessing a program from the external hard drive every time you need to use it than you can certainly delete it from your computer hard drive. Otherwise, make a copy to the external hard drive as a backup in case you have computer problems and leave the original version you want to run regularly on your computer.

Ram is used for temporary storage. Ram stands for random access memory.

If you succeed doing so, your computer will still have its BIOS, of course, from which if you insert any OS CD / USB Drive , you will be able to install it. So if you thought your computer will die... Well, no it's still have something that you can't really delete, unless you break it somehow.

Yes, It usually depends on how much the CD storage. Cds hold more data, pictures, music and other stuff. A floppy disk can only hold kbs and mbs of files. That is less than the cds hold, and floppy disks are getting obsolete. CDs, DVDs, and USB flash drives are the latest to save things on.

Oh, dude, freeing up disk space on Ubuntu is like decluttering your room but with less physical effort. You can start by removing old unused packages with the 'sudo apt autoremove' command, then clean up cached files with 'sudo apt clean'. If you're feeling adventurous, you can hunt down large files with the 'du' command and delete them. Just be careful not to delete anything important, like your collection of cat memes.

An internal hard disk drive has its advantages and disadvantages. Here are the advantages: large storage capacity, stores and retrieves data much faster than a floppy disk or CD-ROM, data is not lost when you switch off the computer, usually fixed inside the computer so cannot get mislaid, cheap on a cost per megabyte compared to other storage media, hard disks can be replaced and upgraded as necessary, can have two hard disks in a machine, one can act as a mirror of the other and create a back up copy.

The advantages, on the other hand, are as follows: hard disks eventually fail which stops the computer from working, regular 'head' crashes can damage the surface of the disk, leading to loss of data in that sector, the disk is fixed inside the computer and cannot easily be transferred to another computer.

Most commonly it is C drive but Hard drives can use any letter in the Alphabet (A-z. Usually when a floppy drive is available it makes itself A drive. and a dvd/cd player usually makes itself D or E. but these are automatically assigned these letters and you can change the letters of the drive (not by renaming won't work like that).

That's a bit like asking how many ounces a glass can hold - there are many different sizes of hard drives. However, the rule for data size conversion is that there are 1024 megabytes (MB) per gigabyte (GB). If it's important to go further, the same rule applies for kilobytes: 1024 kB/MB.

The actual number is 1024 (2^10), but it is often approximated to 1000.

Yes, it is possible to protect your hard drive using the lock command. E.g.

Lock sys: on - this will lock your partition Lock sys: off - this will unlock it.

If you wish to lock a drive other than your main partition simply substitute Sys: for the drive name.

I have a question for you: How do you turn ON write protection on your hard drive to begin with? As far as I know you can't. Hard drives were designed to be written on. You can't install an operating system on it without writing to the disk.

The only way to prevent someone from saving something would be through the operating system's security management. Before you can disable what you think is write protection, you need to understand what is protecting it to begin with.

Simple! Click Start Button > Type: Create and format hard disk partitions > Enter > Right click on your drive (the one that's write protected) > Click Offline > Right click again > Click Online. Voila! tnt4real!

Some hard drives have a jumper on them for write protect. You need to check the jumper settings

I just had this issue with one of my external hard drives. It's an internal drive that I installed into an external case and connects to my computer via FireWire. I knew it couldn't be a jumper setting, because the drive has not been removed from the case since it was put in there. I did NOT turn "ON" write protection at any time. I've been writing to this disc with no problems (daily) up until today. I tried copying a file to it, it popped up a message saying that can not write to disk, disk is write protected. I did nothing to cause this. No settings, attributes, etc. After looking around a bit with no luck (not even from here). I tried a couple of my own things. Found I could not change attributes (cause disk is write protected).

I finally unplugged the drive from the firewire port and waited a few minutes. Plugged it back in and let the computer "find" the drive again, and all is well.

The write protect is in your bios. You select "enable" write protect and it will ask you for a password. Note: not all bios versions offer this option.

I'm considering cleaning up my hard drive of all unwanted ware, especially spyware, and then turning on "write protect" for my hard drive to keep the stuff out. I'll be using a flash pen to surf with which can be cleaned much faster than a hard drive full of stuff and zillions of places for things to hide.

The post above said you turn on this feature in the bios. Can you elaborate on this as to how it's done? I have a Thinkpad r40 and can't seem to find anything on how to do it at ibm or google.

Thanks in advance...

I just had the same thing happen. Hard drive said write protected. Not even a floppy at boot would work. Then I realized when I hit delete for setup, both the hard drive and floppy were flipped to write protect in the bios.

I had the same thing happen to an old P III 800mhz computer; "write protected" message. After reading this I looked in CMOS for a setting for hard drive write protect, I have never heard of this as a bios option (floppy write protect yes, but not harddrive), did NOT find a setting for write protect for either floppy or hard, but I went ahead and did a reset CMOS to optimal setting anyway, booted and all was right with the world!

Thank you for the helpful info. I had tried everything, including fdisk/MBR, cloning to new hard drive, trying to do new install of OS on fresh drive... all failed, thought motherboard or IDE subsystem was hosed. Resetting CMOS WORKED.

If you download Windows SteadyState you have the option to limit who has access to what. You also have the option to lock your HDD. Everything you save will be undone the next time you boot. Here is the link to the download for you.

The capacity of a USB thumb drive depends upon the size of the USB drive. If you have an 8 Gb USB drive it means, can store 8192 Megabytes of data. But it can store only 7680 Megabytes of your data; the rest of the storage is used for the system.

Short answer: An external hard disk is a removable hard disk.

Longer answer: A removable hard disk is any hard disk which is designed to be easily removed from the computer. This includes, but is not limited to, external hard disks. There are also internal hard disks which are removable via a special slot in the front of the machine. Flash-based usb thumb drives are also frequently referred to as "removable hard disks." Even though they are not hard disks at all the OS treats them as such, and so for all practical purposes they can be considered removable hard disks.

It is a combination of RAID 1 and RAID 0. It takes at least four disks for RAID 10.

Refer to A+ at Ch. 6 pages 258.

The simple answer is that a computer needs a hard-drive to store the operating system and data, and a motherboard to hold the many components, circuits , etc. So take away any part and the computer won't work!
