500 Questions

How many movies can a 500 gb external hard drive hold?

User Avatar

Asked by Wiki User

This question is far too general to be answered specifically, but I'll give it a shot! The short answer is... "It depends." The verbose answer is...

It depends primarily on the length and general quality, which directly affects the size, of each movie file you intend to store. For example if you have a 105 minute movie file that is the same resolution and encoded/compressed in the same manner and quality as a DVD movie (MPEG2) then you can count on each file being approximately 2.8GB in size. Using this as a baseline you should be able to store approximately 357 DVD quality movie files on 1TB of storage. However if you have files with a lower resolution (as is often the case in digital cameras and internet videos) or a higher compression ratio (as there is in MPEG4 files) than a standard DVD then you'll be able to fit more files onto the drive, quite possibly many, MANY more. Of course this means that if you have higher quality files, like HD movies, then you won't be able to fit nearly as many on to 1TB of storage.

In summary, the question you should be asking yourself is "What number, type and quality of files to I want to store?" Answering this will tell you whether you need a 16GB thumb-drive, a RAID-0 array of eight 2TB drives (16TB total storage) or, most likely, something inbetween.

I hope this helps, good luck and take care!

How do you format a blank hard drive?

User Avatar

Asked by Wiki User

If you mean "completely erase" it, the term is "Format" and you can perform it from DOS using the command "Format c:".

I think it is beyond formatting. I read today in the New York Times that John Jay College in NYC has adopted a program that covers the free space with zeroes.

The program your probably talking about is evidence-eliminator.com. This program erases all forensic evidence that remains on your hard drive after you format it, and believe you me it's alot. You can recover the entire contents of a formatted hard drive with the right tools. But EE prvents this and effectively "Zero's Out" you hard drive.

Formating a hard drive prepares it for use and deletes previous file names so Windows can't see them. They still exist and can be recovered with several Undelete programs. However, if you wish to remove all data from the drive, just formatting is not enough. "Zeroing" a drive rewrites over the entire drive, replacing previous data with simple 0's. There are several 'Zero' filling programs available on the web and some drive manufacturers include a zero utility on their support sites.The previous answer is pretty good, however it is argued that you can recover a zeroed hard drive. It is possible to retrieve "some" data however "fully recovering" a zeroed hard drive hasn't been done as far as i know.simply doing a "1 zero pass" will invert all the "1's" to "0's" (remember there are only 1's and 0's) hence "zeroing" however there is software available that can detect newly magnetized "0's" it simply re-inverts the "0's" to "1's" if you do a "7 zero pass" it's pretty much impossible to retrieve any information off the hard drive. look into the "DoD 5220.22-m" standard or "gutmann".hope this is useful.

As long as you wipe the drive and reinstall the OS. This is because the drive has settings compatible with one computer that differs from another's settings. Unless both computers are identical.

How do you recover your deleted files from a Wii?

Asked by Wiki User

Ok, I deleted my Wii's mario game file, but you can't retrive it. However, if you find someone who has a higher level/close to you, you can switch files, or copy. In Super Mario Galaxy 2, I used my deleted file for my brother's, and I used my brother's and put my face on it. So now my brother has the one with 0 stars but you can do that, if that helps.

How do you recover a deleted file on mac?

User Avatar

Asked by Wiki User

There was a period when if files got deleted and Trash directory was emptied, all the data would be disappeared completely with no opportunity of return. For nowadays Macs, on the other hand, there can be many of file undelete options. You will need to install a proper backup service in place to resolve this kind of commotion.

Apart from the apps that Apple itself can provide, a couple of additional applications that can be selected that can offer same services also exist. This short article includes a look at data recovery as a whole along with cool advise.

When your system deletes a document, the thing the operating system really does is label the storage on the hard drive that the data takes as free space. The information is still present there, but your Mac is fully happy to put new data over of it, at which point the recovery process will be much more complex. This shows you should do as little actions as possible before you find the information you are looking for, since each time you download a new file, or each time the system writes something to your hard drive, your chance of undeleting the data decreases.

You likely need to get a high quality recovery apps if you do not use one currently.

Check out the following:

Data Rescue II offers a neet graphical interface that will help you with your information recovery needs

photorec.png: this tool can be operate via terminal or command prompt.

Following the installation of the application that you wish to use to unerase the lost document, you have to start scanning the HDD for the lost file or files.

This procedure varies and depends on the tool you have, but the main principle is identical for most of them: simply direct the application at the hard drive or place that was holding your erased information and commence the search.

As soon as the search is complete, you are going to get a huge list of various file names.

Generally files on the list are no more than temporary cash that your system used for common operation, and you do not need to think about them. You are just looking for the file type and name that corresponds to what you deleted.

As soon as you find the information you were searching for, save it to a different disk.

The section below lists a couple of of various programs that can be utilized if you by accident wipe document.

Mac Recovery: To unerase the documents that has been erased after drive formatting, use a previous backup or run a Mac File Recovery app.

Macintosh Recovery remains one of the known apps that can restore wiped files from Mac HDDs.

This app works on most OS variations.

It is a simple app that includes a variation of complex recovery principles.

TimeMachine: All Macs purchased after November 2007 already have with the up-to-date OS, the Leopard.

Time Machine is part of this OS, which is a application that can undelete your files with ease.

Simply bring up the app and go back to the point where you want to access your file; then click Restore, and it will automatically be placed in its original folder like before being removed.

MacKeeper: among lots of different MacKeeper capabilities, the Undelete utility is a powerful data restoration solution used to undelete deleted files even after trashing.

Undelete can bring back a wide range of file types from disk.

FileSalvage: this app lets you to back up and retrieve lost documents easily.

Bring up the tool and choose the settings to your liking; after that it will be possible to navigate back and see where the needed information is.

How do you fix the hard disk file from a ps3 system when its corrupted?

User Avatar

Asked by Wiki User

PS3 uses proprietary file system. And if you do no have tools that came with your PS3 I afraid there is nothing you can.

Overall damaged files are next to impossible to recover or restore. There are exceptions but not that many.

You might want to call the manufacture and ask for help. Also try to use Google, I have not found any helpful information.

Will magnetic fields damage hard drives?

User Avatar

Asked by Wiki User

Computer disks (hard drives or older floppy drives) store their information by creating a magnetic charge on a tiny spot of the disk for each little bit of information, which can be read again later. Passing a strong magnetic field over the disk changes the saved charge and it can't be read again as organized information.

CDs and DVDs don't store this way, so are safe from magnetic fields.

How do you format a hard drive with Windows 95?

User Avatar

Asked by Wiki User

For any disk OTHER THAN THE ONE YOU BOOT FROM, simply open a command prompt and type:

format d: (where "d" is the designator of the disk that you want to format)

OR

open windows explorer, select "my computer" then right click on the drive you want to format (again, it can't be the disk you boot from"

If you want to format your C drive you'll need to boot from some other medium, such as the installation disk or a floppy.

What scsi standard has a maximum transfer rate of 80 MBps?

User Avatar

Asked by Wiki User

SCSI (Small Computer System Interface) transfer rate is specified as mbps which is: "MegaBits Per Second". Note it is not "megabytes" per second. This can be somewhat misleading, since a higher number is derived from using the "megabit" rating rather than the "megabyte" rating. Obviously there are 8 bits in a byte, so specifying the rate in "mega bytes" would result in a 5 megabyte transfer rate specification.

Why is a hard disk known as a storage device?

User Avatar

Asked by Shohailuzzaman

A hard disk is known as a storage device (and vice versa) because the terms are interchangeable. Your hard drive on your computer is known as secondary storage (RAM is primary storage). This secondary storage is where nearly everything (music, documents, pictures, videos, etc.) is stored on your computer. It goes by the name of Hard drive, hard disk, storage device, and many other names.
