I used a C400 64GB USB2 Flash Drive EMTEC green to record digital MP4 using a converter of VHS tapes and transferred them to a PC. This has worked very well. But a moment after I deleted one by one all the processed files, I found that by viewing the properties, approximately 2GB of the space remained occupied when no files were reported.

That had already been the case with key 8 or 32GB, because recording ended badly, and in this case I proceeded to reformat to recover all available space.

So I reformatted the default key with exFAT 64B and 32 kilobytes. But since then I can no longer use the key on the converter. As I do not know what the characteristics of this key were before reformatting, I sent a request for information to EMTEC to be able to reproduce the initial format that worked correctly.

But I received no response. I tried to format in FAT32 but can not do it because I have such options as exFAT or NTFS for reformatting the key. Who can help me find my intitial formatting Flash Drive

Could it be the $MFT? – Jerry Sweeton Jan 18 '13 at 14:02

Its not the machine ... Its the flash drive that has exfat which is replaced with fat32 ... the difference is:

1.exFAT allows for higher drive capacities than FAT32. 2.exFAT has a larger file size limit than FAT32. 3.exFAT uses a free space bitmap while Fat32 doesn’t. 4.FAT32 has greater support than exFAT. 5.FAT32 doesn’t have file number limits while exFAT does.

the easiest solution would be to find another machine and use it to format the USB drive to fat32.
