Use a third-party utility, like "FAT32 Format," to format larger USB drives with FAT32. Alternatively, launch PowerShell as an Administrator and run "format /FS:FAT32 F:" in the Window to format the "F:" drive as FAT32. Swap "F:" for the drive letter assigned to your USB drive.
Formatting with this tool is much quicker than the command line method described in the next section. This tool took a few seconds to format our 64GB USB drive that took us about 40 minutes in PowerShell.
One thing to note here: you'll need to close any open File Explorer windows before you format the drive. If you don't, the tool will interpret the drive as being used by another app and formatting will fail. If this happens to you, just close the File Explorer windows and try again. No need to relaunch the tool or anything.
The quickest way to find out what letter is assigned to the drive is to open up File Explorer, go to "This PC," and just look. Alternatively, you could run "diskpart" in PowerShell, Teriminal, or the Command Prompt, then run "disk list" to get a list of disks attached to your PC and the correspodning drive letter.
The screenshot below shows a known good 4GB, properly formatted FAT32 USB stick.EaseUS Partition Master recognizes as FAT32, Windows 10 Disk Management sees it as RAW.Partition Master however cannot read the disk contents.If I try to re-format the drive (or smaller drives) to FAT32, it fails.
Please !!!This computer will not read any FAT32 drive, USB, internal or external.The drives I try are all correctly formatted, and readable.I plug in a known, good drive, and the computer reports that it needs to be formatted.Trying to reformat to NTFS works fine, but a format to FAT32 fails, and the machine wants to format it again... etc etc.
It is possible that your windows might not be assigning letters to the drives properly. You should open run (windows + R), and then type 'diskmgmt.msc'.If you can view your drive there, just simply assign a letter to drive by right clicking on the partition of your usb drive and assigning it a letter.
There are lots of comments and explanations regarding this problem around the internet. However, if none of them work for you, and you already DISMed and SFCed the crap out of your Windows, then this is the answer for you.
You need to make sure that your Windows does not use the wrong support partitions. If you have e.g. more than a single hard drive installed in your computer and you re-installed Windows a couple of times already, then it may happen, that at one point Windows installed its secondary partitions to the wrong drive. So, when you re-install Windows, the new Windows may refer to the wrong partitions and this is exactly what is causing this issue.
If you remove the non-fitting partitions or the entire storage media having the non-fitting partitions, then your Windows 10 will start to recognise all FAT16 and FAT32 storage media, as it should, immediately after a reboot.
You may rest assured, that all the solutions implicating that your Windows "must" be corrupted in such way are simply not correct in your specific case, especially if you are finding this answer as a last resort.This issue can happen without any corruption or similar 3rd party issue -- like e.g. hardware problems or 3rd party drivers -- whatsoever.
Recent windows versions do include startup optimizations that involve caching disk data somewhere different than that same disk, which causes the behavior that you found when the disk is accessed by a different OS.
You can use the Group Policy Turn Off Boot And Resume Optimizations (located in Computer Configuration\Administrative Templates\System\Disk NV Cache) which should make Windows only store the files that on their partition. There are also some other Nonvolatile Caching settings available, but that one should fix your issue.
The problem also happens on Windows 11*, and it's not limited to FAT32 partitions or even to the partitions being on the same Drive. Apparently Windows does this to all the internal drives it can access (I tested it with FAT32 and exFAT partitions on both the same SSD as Windows itself and different internal drives).
Other caching options seem to only apply to external drives and don't really solve the problem for internal drives (an SSD and an HDD in my case), but if that's the case, the other answers to this question cover that.
* Funnily enough, with Fast Startup on, Windows 11 didn't seem to notice even drastic changes, such as reformatting the whole drive and changing its partition table. I didn't dare test what it'd do if it tried to write to the drive in that state.
In Windows 10, when you want to format a partition specifically as FAT32 (for example an SDcard that is going to be used in your phone) when you right-click the disk and choose format, only NTFS and exFAT are shown as possible format options.
While LPChip's answer is 'correct' and should work in most cases unless the partition is over 32gb. I typically use a bit of third party software from ridgecrop that does the same thing but handles larger partitions. I've used their command line fat32formatter extensively over the past few years.
Right click on the volume and choose Shrink Volume..., then shrink it to 4GB or less. After that, both FAT32 and Quick Format options will be available in the Format... dialog.
FAT32 file size limit is 4GB, and Windows will not allow you to create/format a FAT32 partition larger than 32GB. CrimsonKidA is correct, if you need to work with it with macOS, ExFAT is what you are looking for. macOS can access NTFS, but as read only.
You might want to give R-Drive Image a look. Supports many different filesystems and pretty affordable at $45 for a single machine, perpetual license. I have used this for many years, very easy to use and has never let me down. The link below is to their page which outlines the filesystem support.
I would use NTFS. It can be read on both systems. If you need additional write access to the drive through OS X, there are third party drivers you can use, or even some terminal trickery. Overview here
Go into Control Panel and view by either large or small icons. You should then see Backup and Restore. I have used it and it is decent but as others have mentioned, a third party software like Veeam would be a better solution.
But at home I trust Acronis True Image 2019 on my system. Been using it for years. It gives me peace of mind especially since the inception of crypto malware. Pricing is pretty good. @francis-spiceworks is offering a 50%. Not too shabby.
Uranium Backup Free is a good product and includes a scheduler if that floats your boat - Not a perfect solution but I have used it for years and been able to restore when required - I like the fact that the backup can be a good tree replication of your source drive (within a zip if wanted but not if not) and it can handle incremental backups also.
You probably formatted it on X os and it did it a different way, (not really good at explaining it lose for words) but I re-imaged a drive within Ubuntu and the way it did it, in windows it showed the drive being smaller. I would connect the drive to windows and format it via CMD
Formatting a drive is the same as if you buy a new hard drive since the process erases all the data in one fell swoop. With this method, you can clean internal as well as external storage media. In this tutorial, I will explain steps to format a hard...
Formatting only cleans the drive of contents so to speak. Partitioning is what selects how much space that partition has. If the drive is 6TB then the partition needs to be that size to be a viewed as 6TB. Are you creating the partition using Windows or MAC? If in Windows go to control panel, Administrative Tools, Computer Management, and check Disk Management. It should show the size of the drive and what partitions are assigned to the drive. I would be curious if it sees the drive as 1TB total or sees it as a 6TB and only has a 1TB partition set. If the drive shows as 6TB but only has a 1TB partition set you can extend the 1TB to use the remaining 5TB of space.
Also windows 10 has the windows 7 style drive backup too - you have to access it though the control panel. You may need to configure the drive mount type as non-removable before it may be considered for inclusion as a selectable backup drive.
I'd like to setup a Windows 98 SE system that boots into the included MS-DOS 7.1 command line, and which can also run Windows 3.11. I've seen various disjointed posts online that suggest this is possible without using multiple boot partitions, and that all 3 OS's will support a large FAT32 partition and Long Filenames (LFN).
NOTE: I'm doing this because I want the convenience of a single large drive/partition that can run most of the software from the 1990s for DOS, Win3, and Win9x. And I'm hoping DOS 7.1 is also backwards compatible enough to run some 1980s software too.
I'm going to post a frame challenge answer and say that if your goal is to run MS-DOS and Windows software from the early 90s and before then you don't want to do what you propose. Instead you're better off just installing Windows 98 SE and booting (or rebooting) into MS-DOS mode for the few applications that need it. In particular trying to force Windows (for Workgroups) 3.11 to work under MS-DOS 7.1 requires various hacks and will likely result in something that's less compatible with applications.
Microsoft has always taken backwards compatibility very seriously (even today, the 32-bit version of Windows 10 will run many old 16-bit Windows applications), and Windows 98 wasn't an exception. It's predecessor, Windows 95 wasn't the revolutionary new operating system that it superficially appears to be. It was just an evolution of Windows 3.11, with a lot of new features but also with a lot of the same code. The most likely reason for an old Windows applications not to work is because of new hardware. Things like drives being bigger than the software assumed possible, or the CPU being 10 or 100 times faster. Problems that your proposed setup wouldn't fix.
