How to fix “Cannot copy file. The Parameter Is Incorrect” error


Had a head-scratcher today whilst migrating some data from a 500GB External USB HDD to a new 1TB External USB HDD, both attached to a client server.

Some of the data refused to copy across, throwing up a “Cannot copy file. The Parameter Is Incorrect Error” each time. Same error when the copy was attempted in DOS, RoboCopy or XCOPY.

Upon investigation, each of the problematic files were 10GB+ in size – and suddenly the realisation dawned – that the new external HDD was formatted as FAT32 and not NTFS, and thus suffered from FAT32’s 4GB file limit.

A quick format to NTFS on the drive, and I was able to copy those large files across without issue.

Obviously, I have become so used to working with large files nowadays that sometimes I forget things weren’t always this way!

  1. FAT32 may have been OK back in your atari days, but today it just doesn’t cut it. :)

  2. How weird is that…had a conversation with a customer this week over the same thing
     
    Pointed him to this: http://support.microsoft.com/kb/314463 
    Reformatted the drive and all sorted!

  3. FAT32 didn’t exist in the Atari days – it was FAT16

    I use 7-Zip to split any files larger than 4GB into 650MB Chunks. (7-Zip limitis what size you can split them into but, anything under 4GB works.) I then use Robocopy to copy each chunk down and use 7-Zip to reassemble the chunks back into the file. It even works with SQL Backup files. I haven’t tried to automate this yet as I don’t have to do it too often.

  5. GSCopy Pro v6.0 (RoboCopy Alternative) with Open File Agent
    GSCopyPro is a single command-line tool (CLI) that can copy, replicate and move files from one folder to another. This folder can be on the same machine/ server or another server elsewhere. What makes GSCopyPro stand out from other competitors is the fact it works on 32-bit as well as 64-bit systems and has no restrictions. It can easily be scheduled to run as a scheduled task and fully automated. GSCopyPro also comes with an open file agent which can copy files that are locked/ opened by other processes. This feature is supported in all windows versions from widows XP/ 2003 and later.

  6. Thanks! Richard, I’ve had a real AHA! Moment just now, after hours and hours of frustration before I read you post here. AHA! Of course I should have known that – because I did – but I just didn’t think of it like that. Thank you, thank you for making your post here! By the way, the free tools sound good, and the 7Zip split is another interesting idea too. Cheers, everyone!

  7. There is a free tool at

  8. Thanks – free tools are always good to hear about! :-)
