Kada izbrišete sve iz bljeskalice i ponovno ga formatirate, mislite da bi ga trebalo "prikazati" kao potpuno prazno kada je označeno, no to možda i nije uvijek slučaj. Imajući to na umu, današnji SuperUser Q & A post ima odgovor na pitanje zbunjenog čitatelja.

Pitanje

SuperUser čitač Andrew želi znati kako se može koristiti prostor na prazan i svježe formatiran bljesak voziti:

I recently purchased a SanDisk Cruzer CZ36 16GB USB 2.0 flash drive with FAT32 as the default formatting. I need to store files that are larger than four GB on this flash drive, so I decided to reformat the flash drive as NTFS. The flash drive also had some SanDisk SecureAccess software preloaded on it that I did not want. On my Windows 7 system, I right-clicked on the flash drive in Windows Explorer and selected Format. I did a full format by deselecting the Quick Format option.

After reformatting the flash drive, Windows tells me that it is not completely empty. If I right-click on the flash drive in Windows Explorer and select Properties, Windows gives me this information:

Why is this the case even though I just formatted the flash drive? Is this to be expected or are there some files still lingering on the flash drive? When I open the flash drive in Windows Explorer, no folders or files appear even though my system’s settings are configured to show hidden items. I find it worrisome that there is a total of 91.7 MB somehow being used on this supposedly “empty” flash drive.

Odgovor

David Schwartz za SuperUser ima odgovor za nas:

This is normal. An “empty” NTFS file system has a number of internal files such as the master file table (“$MFT”), the log file used for file system recovery (“$LogFile”), the volume descriptor file (“$Volume”), and so on.

The largest one is probably the cluster allocation bitmap (“$Bitmap”) that keeps track of the space that is used and the space that is free. This is pre-allocated when the file system is created.
