How do you get the floppy disc out of the Macintosh classic?

To eject a floppy disk from a Macintosh Classic, first ensure the computer is powered on. Then, locate the "Eject" button on the front of the floppy disk drive and press it; this should release the disk. If the disk doesn’t eject, you can also try dragging the disk icon to the Trash on the desktop, which serves as an eject command. If all else fails, you may need to gently use a paperclip to press the manual eject button located near the disk slot.

What does No ID address mark was found on the floppy disk mean?

The message "No ID address mark was found on the floppy disk" typically indicates that the floppy disk is either damaged or corrupted. This error arises when the disk drive fails to locate the necessary header information that identifies the disk's format and data structure. It can also occur if the disk is not properly formatted or if there are issues with the drive itself. In such cases, data recovery may be difficult or impossible.

What storage media is not a replacement for floppy disks?

Optical discs, such as CDs and DVDs, are not a direct replacement for floppy disks due to their different usage scenarios and storage capacities. While floppy disks typically offer limited storage (1.44 MB for the standard 3.5-inch disk), optical discs can hold significantly more data (up to 700 MB for CDs and 4.7 GB for DVDs). Additionally, floppy disks were often used for booting and transferring small files in older systems, while optical media has become more associated with audio, video, and large software distributions. Thus, although they serve some overlapping functions, they cater to different needs and contexts.

Something is a magnetic disk storage device that has maore capacity than a floppy disk?

A magnetic disk storage device with more capacity than a floppy disk is typically a hard disk drive (HDD). Unlike floppy disks, which generally hold 1.44 MB, HDDs can store vast amounts of data, often ranging from hundreds of gigabytes to several terabytes. They use magnetic storage to read and write data on rotating disks, making them suitable for storing large files and applications.

What is the intervertebral disks are composed of?

Intervertebral disks are composed of two main components: the annulus fibrosus and the nucleus pulposus. The annulus fibrosus is a tough, outer layer made of concentric rings of fibrocartilage, providing strength and stability. The nucleus pulposus is a gel-like center that absorbs shock and allows for flexibility and movement between vertebrae. Together, these structures help maintain spinal integrity and facilitate movement.

What disk can store up to 680 MB of data?

A standard 3.5-inch high-density floppy disk can store up to 1.44 MB of data, while a CD-ROM (Compact Disc Read-Only Memory) typically holds up to 700 MB of data. However, if you're specifically looking for a disk that can store up to 680 MB, it would be a writable CD-R (Compact Disc Recordable) or a CD-RW (Compact Disc Rewritable), both of which can typically hold around 650-700 MB of data.

What is the function of floppy disk drive?

Answer--In the purest sense, the function of a floppy disk drive is to provide a means of writing/reading data on/from floppy disks in an industry standardized method. Floppy Disks were invented as an improved means for storing/transporting data on/from computers.

The universality and standardization of disk storage technologies was important to the personal computer industry. By standardizing these complex technologies, computer manufacturers were able to, over time, inexpensively source drives and disks, thus reducing the cost of the computer systems. This made PC's more affordable for everyone.

Ok, lets say you type something up in a word processor want to save it, but not directly on the computer. You can buy 3 1/2 floppy disks (you can find them in most kind of computer/department store - assuming it has an electronics department). You put this disk into the floppy drive and then click 'save as' on your document [click on FILE on the top left-hand corner]. You bring down the top box (you click it, and there'll be a list of places on your computer - eg; 'Desktop', 'My Folder' etc). Near or underneath 'My Computer' in that box, click 'Floppy Drive A' or whichever icon has a little picture of a floppy disk on it, and it will load up the disk you put in it. You then hit save, and you're done!

If you want to open up a file on a floppy disk, you put it in, click on 'My Computer', look for the icon with the Floppy Disk on it, double click, and there should be your file - ready and waiting.

ANOTHER ANSWER

To add to that, since then, floopy drives have been replaced by flashdrives. IN some cases a CD replaced the floopy disk.

What is hard sector and soft sector in floppy disk?

A hard-sectored floppy disk (5.25") has timing holes (typically ten) drilled through the disk at evenly-spaced intervals around the disk at the same radius as the index hole (which is one hole drilled between two of the timing holes). The timing holes indicate to the disk reader / writer / controller where the sectored are located on the floppy disk.

A soft-sectored floppy disk has a single index hole and no timing doles drilled in it. The spacing of the sectors is determined by set time intervals from the passage of the index hole as it rotates. For example if there are ten sectors each would be spaced at 1/10 of the time it takes the disk to rotate. The controller for a soft-sectored disk drive must be able to control speed and measure time more carefully than a hard-sectored disk drive. A soft-sectored disk can't be read or written by a hard-sectored disk drive (and vice versa) unless the disk controller has been written to deal with the different number of holes.

What floppy disk hold more info 3.5 or 5.25?

3.5" and 5.25" were available in a variety of capacities. 3.5" disks maxed out at 2.88 MB, while 5.25" topped out at 1.2 MB. It is quite possible for a 5.25" disk to hold more data than some 3.5" disks.

What was the original size of the first floppy disk ever made?

The the original size of the first floppy disk ever made, was 8 inches and stored 80 kilobytes.

What is the smallest amount of storage CD hard drive floppy disc or ram?

In order of least to most, the storage capacities are:

floppy disk, CD, RAM, hard drive.

3.5" HD floppy disks normally have a capacity of 1.44 megabytes. Older disks had less.

CD's used for data storage have a data capacity of about 700 to 900 MB, depending on the type.

Most computers now have a few GB of capacity in RAM.

Typical hard drives now have capacities of hundreds of GB - although terabyte drives are now available too.

Notes:

  • Some computers (especially older ones) have very limited ram and may actually have less storage capacity than a floppy disk, but most of them currently have much more.
  • When CD's were first introduced, they had more capacity than computer hard drives common at the time.The reverse is now true.
  • A single-layer DVD-ROM can hold 4.7 GB of error-protected data, more than 6 CD-ROMs. This exceeds the RAM in many computers.

Can files saved onto floppy disk only be accessed by other users without the disk?

Short answer to this. No, the data can't magically jump from one computer to another (providing the computer's aren't networked. If they were however, it would be unlikely the files would be stored on floppy)

short answer: no, not normally. long answer: maybe. if the file has a backup copy written on the harddrive somewhere, and someone knows where to look, then, yes.

take the screws off and throw a bucket of water on top of it and then get a blow dryer and dry i did that and now iam in hospitel and pepol are feeding me ice cream and chocolate EVERY MINIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The files cannot be accessed unless they are stored somewhere else on the system or they are in temporary files. in short; no.

NO.

In fact, your question has a false answer. Files saved onto a floppy disk cannot be accessed from the disk unless the user uses the disk in the computer. The only way to access the same files without a disk is to have a backup on another disk, hard drive, or other medium.

Is a rescue disk the same thing as a floppy disk?

No. A 'rescue disk' is any media that is used to recover a corrupted or damaged system. it can be in the form of a floppy, CD, DVD, or perhaps even a USB flash drive. A floppy disk can be used for other purposes besides a rescue disk.

How do you upgrade a toshiba satellite t2130cs to win98se even though it only has a floppy drive and no CD drive?

Yes. There are a couple ways you could do this.

1. You could purchase an external CD-ROM drive that connects to the parallel port. Using a special DOS boot floppy and driver, you could then launch the Windows 98 setup CD.

2. You could remove the laptop's hard drive, plug it into another computer, install Windows 98, and then place it back. It will likely be missing some drivers, but you can supply these on floppies.

What is used to record information from the computer onto a floppy disk?

That would be a floppy drive. Information is passed from the software and/or the operating system to the drive controller. From the drive controller, it is passed to the logic circuits on the drive and to the drive heads. The logic circuits also turn on the drive motor for an appropriate amount of time.

If you have 2 internal hard drives Drive A having OS and Apps on it and Drive B having music and data on it would reformatting Drive A affect Drive B in anyway?

You need to be sure you actually have two physically separate hard drives, and not just two partitions. If you do have 2 drives, then the second drive shouldn't be affected. However, I can't stress enough to BACK UP YOUR DATA before you do anything that could risk data loss. Formatting a physical drive will not change another physical drive directly, but the support files (dlls,libraries) that get loaded into the OS on drive A are gone and a lot of programs (even if the executables aren't deleted) will not work without a complete reload into the new OS.
