6 gig ISO file XFer from win7 to external drive says it's too large?

I am trying to use a 500 gig sata drive for storage transferring data through a USB to hard disk tool/cable.

The tool is a Vantec USB to IDE/SATA adapter. Vantec ? Vantec SATA/IDE to USB 2.0 Adapter - CB-ISATAU2 - 2.5"/3.5"/5.25" SATA/IDE to USB 2.0 Adapter

I bought it to be able to have more storage for my laptop and at 20 bucks it was cheap solution cus I already had a new 500 gig drive.

I haven't really used it much and this is the first time I tried to transfer something with large file sizes. I do not know if it's the tool, hardware limitation but I suspect it's the file system on the external drive?

It's Fat 32. I Can format it with NTSF and try to recopy the data.. ( luckily as I had not moved. only copied it)

I don't remember now but there was a reason I left it as Fat 32. Does this sound like it should fix the problem or should i try another solution first?

Edit:

I remember why I wanted to leave the drive Fat 32. That was so I could also use the device and drive to copy data over from my Linux and BSD operating systems. Bummer unless I find a way around this.

File Allocation Table - Wikipedia, the free encyclopedia

"The maximum possible size for a file on a FAT32 volume is 4 GB minus 1 byte or 4,294,967,295 bytes."

Looks like your suspicions are correct.

I'd think the solution is to make 2 partitions on that 500 GB drive: a FAT32 partition for Linux/BSD and an NTFS partition for Windows. Or two entirely different drives.

Yeah that was the problem. Good idea, to partition the drive each with a different file system. I might just pick up another drive anyway though, as I see they are getting cheap.

Thanks.

Is this why I can't transfer some avi files via usb 2.0 to a thumb drive ? I have a thumb drive that is 14 gb's. My large avi movies can be 5 gb's or more. Error says it's too large a file.

You should have started a new thread rather than appending to one that's more than a year old.

Yes. Format the USB flash drive as NTFS, and that'll fix the file size limitation. (eFAT might be OK too, but I have never tried that.)

Some OSes (DOS, for example) don't natively work with NTFS, but the versions of Windows that descend from NT (2000, XP, Vista, 7, and 8) do.

Can't transfer large file to external drive
I'm trying to do a simple back up. One 12g folder transfer to an external hard drive. Drag and dropping will will stop working about 1/4 of the way through. I tried TeraCopy and that gets through about 6g before it stops working. Any idea what is wrong?

Why do files moved to an external drive not behave the same as those same files in an internal drive? I noticed that if I do anything to a file that is in an external drive, that file can not be saved under the same name (read only). In order to do so one must save it internally and then copy or...
