Access a USB drive from Linux and Windows

Access a USB drive from Linux and Windows

I want to be able to attach a USB drive to Red Hat Linux 8.3 and
write files to it and then be able to take the USB drive to a Windows
machine and read the files. I have a USB drive and I've been trying
to achieve this goal without success. The drive works because I have
been able to access it from Windows by totally reformatting it. I
tried formatting a 31 MB partition on partition 1 using Windows and
then taking it to Linux. Linux wouldn't let me mount the volume.
Windows wouldn't let me partition the entire drive as a FAT partition.
I tried using Linux fdisk and mkfs -t msdos /dev/sda1. That resulted
in error "Attempting to create a too large file system". Any ideas?

Gonna be tough, since Redhat 8.3 doesn't exist.

Shouldn't be a problem; USB Mass Storage devices that follow specs are
well-supported and so are FAT32 filesystems.

So what happens when you try to mount it under Linux?

What was the output from dmesg when you tried?

If the space is smaller than 2G, it should be FAT16 (type 0x06), larger
than 2G but smaller than 8G, it should be FAT32 (type 0x0b), if it's
larger than 8G, it should be FAT32-LBA (type 0x0c). If you get the
types wrong, 'Doze can get annoyed and randomly scribble on your data.

mkdosfs -F32 /dev/NNN on partitions larger than 2G, since mkdosfs uses
FAT16 by default. HTH,

Thank you. I ran fdisk on the USB drive and changed the type to 0C.
Then, I used the mkdosfs command and I'm able to use the USB drive on
both machines.
