A standard high density double-sided floppy disk holds about 1.44 mb.
Single Sided, Double Density This is a floppy disk format.
Computers made today generally do not have any floppy drives at all. PCs traditionally had 2 floppy drives (A: and B:) but might have only one of these. The original Mac had 1 floppy drive. Early microcomputers could frequently have as many as 4 floppy drives. (I had one with this capability but I never connected more than 3 floppy drives, these were 8 inch double sided double density drives).
Depends on the floppy:Original IBM System/370 microcode 8 inch floppy - 80K bytesShugart OEM 8 inch floppy (single sided, FM recording) - 128K bytesShugart OEM 8 inch floppy (single sided, MFM recording) - 256K bytesShugart OEM 8 inch floppy (single sided, MFM recording, half width head) - 512K bytesShugart OEM 8 inch floppy (double sided, MFM recording, half width head) - 1M bytesShugart OEM 5 inch floppy (single sided, MFM recording) - 110K bytesApple ][ 5 inch floppy (single sided, GCR recording) - 140K bytesShugart OEM 5 inch floppy (double sided, MFM recording) - 220K bytesApple ][ 5 inch floppy (double sided, GCR recording) - 280K bytesIBM PC 3.5 inch floppy (MFM) - 720K bytesApple Macintosh 3.5 inch floppy (GCR) - 800K bytesIBM PC 3.5 inch floppy (HD MFM) - 1.44M bytesApple Macintosh 3.5 inch floppy (FDHD) - 1.6M bytesNote: many more floppy types and formats than are listed above are omitted because of limited usage or obscurity.
The most common ones most people are familiar with were 1.44MB, but there were many sizes of "floppy disk" from about a hundred kilobytes to a couple hundred megabytes. Nowadays, the answer is 1.44 for a double sided high density 3.5" floppy disk. This answer is quite different for other types of floppy disks. There are single sided, double sided, single density, double density, high density , 5.25", 3.5", and 8" floppy disks just to name a few of the many, MANY variations. * low density capacity: 360 kbytes * hi density capacity : 720 kbytes * double hi density: 1.44 megabytes There are other (rare) formats that can hold more.
Modern 3.5" floppy disks were/are double sided. Earlier 5.25" floppy disks started out single sided but you could cut out a read only slot and flip them over and use both sides, no guarantees though. Even earlier 8" floppy disks were also single sided but could likewise be cut and flipped over. This is from my own experience not from research.
A double-sided high-density 3.5-inch floppy disk can store up to 1.44 MB of data. This capacity is achieved by using both sides of the disk, with each side able to hold 720 KB. Floppy disks were commonly used in the late 20th century for data transfer and storage, but they have since been largely replaced by more modern storage solutions.
There have been three formats of 3 1/2" Floppy disk: - 3½-inch HP (single sided) - from 1982 - 280KB - 264KB Formatted Storage Capacity - 3½-inch DD (double sided) - from 1984 - 1 MB - 720KB Formatted Storage Capacity - 3½-inch HD (double sided) - from 1987 - 1.44 MB - 1440KB Formatted Storage Capacity
Sorry here is a better answer: Single-sided, 8 sectors/track: 160 KB (1981) Single-sided, 9 sectors/track: 180 KB (1983) Double-sided: 360 KB (1983) High-Density: 1.2 MB (1984)
I know there are double-sided wrap skirts.
A roll of tape or double-sided tape.
Possibly with another Hard drive or with a good amount of double sided dual Layer DVD's. Depending on the size of the hard drive. basically you use a backup program.
