Cannot copy file. The Parameter Is Incorrect

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!

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

    Pointed him to this: http://support.microsoft.com/kb/314463 
    Reformatted the drive and all sorted!

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