Now I am using VeraCrypt (free and open-source) to manage a secure volume (like a 'vault') within my thumb-drive, and FreeFileSync works perfectly with it. Unfortunately I lost it (luckily my data was secure!), and now I'm trying to find a new one with the same software, as I don't know of any other thumb-drive manufacturer that does what I (and you) need, built-in, in such a simple and secure way, without paying a high price. I had a Toshiba USB stick that was much better - it had a Public partition, which was visible when you inserted the drive, and a Private partition that became visible (and accessible as a normal drive) when you unlocked it. So I think that the SanDisk SecureAccess is only suitable for files/folders that you're happy to copy manually - it's no use when you have huge folders that you want to synchronise daily, using FreeFileSync or rsync or anything else. The only automated copying it supports is making a backup, from the USB drive to your PC. The truth is that FAT32 has a theoretical volume size limit of 16 TB, with a current practical limit of about 8 TB-plenty for most USB drives.Unfortunately I don't think it's possible - the SanDisk SecureAccess 'vaults' are only accessible via very limited interfaces, through their software application. Specifications put out by manufacturers on file systems as they pertain to drive size created the myth that FAT32 can only be used to format drives between 2 GB and 32 GB, and that is likely why native tools on Windows-and other systems-have that limit. Every major operating system and most devices support it, making it great for drives you need to access from different systems. The advantage to using FAT32 is portability. If you do need those larger file sizes, you’ll need to stick with something like NTFS or exFAT.

RELATED: What File System Should I Use for My USB Drive?įAT32 is a solid file system for external drives, so long as you don’t plan to use files over 4GB in size. Swap 'X:' for the drive letter assigned to your USB drive.įor whatever reason, the option to format USB drives larger than 32GB with the FAT32 file system isn’t present in the regular Windows format tool. Alternatively, launch PowerShell as an Administrator and run 'format /FS:FAT32 X:' in the Window to format the 'X:' drive as FAT32.

Use a third-party utility, like 'FAT32 Format,' to format larger USB drives with FAT32.
