Today, tenth episode of season 3 of our Sunday quiz. And a change in the game: this will be a question for the Nostalgeek. Indeed, find photos of devices that are not referenced by Tineye and Google becomes complicated...
The scale remains the same: 2 points for the first correctly responds in comments, 1 point for the other. The question will be asked Sunday, an index will be posted on our Facebook page Monday.
The issue: Pierre branch a 1 GB (formatted in FAT32) key on his computer. He began by copying a file to 200 MB (depending on the OS) on the key from a computer under OS X Lion. Then he then copies a 400 MB file (depending on the OS) since Mac OS X Leopard. Then it runs under Linux and adds a file of 200 Mio (depending on the OS). Then, it runs under Windows 7 and adds a file of 100 MB (depending on the OS), a 1 MB file and a file of 3 KB. In the end, the key indicates that there are 799 109 120 bits on the key. What is the actual capacity - bytes - the 1 GB USB key.
Good luck.
Important: to avoid the "spoilers" place your answer between the following tags. [# ffffff] Your answer [/ # ffffff]. The answer will be written in white, which will avoid to see the responses of other competitors "without doing so express". Comments giving a response without being placed in these tags will be not taken into account.
As to habit, an index on the Facebook of Tom's Hardware page.
A somewhat complicated quizz correct, some being gone further than expected cash data and including the size of the directories created by some operating systems. Explain the calculation first.
A USB 1 GB formated in FAT32 by default clusters 4 KB (4096 bytes), which therefore implies that all files must be a multiple of this number (and rounded above for problem) but as the free space indicates, the clusters are here 512 bytes, there was a trap.
For OS X Lion, 1 MB is worth 1 million bytes, as recommended by the International System. 200 MB is therefore file 200 million bytes, or 200 000 000 bytes.
For Mac OS X Leopard, 1 KB is 1024 bytes (which is false) and therefore 400 MB worth 419 430 400 bytes, a multiple of 512 bytes.
Linux follows the standard and 1 KiB is 1024 bytes and thus 200 Mio worth 209 715 200 bytes, a multiple of 512 bytes.
Windows 7 does not follow the standard and 1 KB is 1024 bytes. 101 MB are therefore worth 105 906 176 bytes, a multiple of 512 bytes.
3 KB file is over the size of a cluster and therefore requires 3072 bytes on the hard disk.
The remaining capacity is expressed in bits and after conversion, therefore obtained 99 888 640 bytes.
The total capacity of USB stick, in bytes, is therefore of 1 034 944 512 bytes (1 034 MB instead of 1 000 MB expected).
