hello guys
recently i have buy a Transcend 320GB external HDD. My problem is that when iam copying any 4Gb above .ISO file from my internal HDD to external HDD, it's actually copying 3.99GB everytime. Can anyone tell me what kind of problem is this?????????

What is the File System of your external hard drive, is it Fat32 or NTFS? Also are you able to open the iso file that you stored in your external hard drive? Repartition your hard drive rather than reformatting the whole thing. Resize existing partition to something like (currentsize - 10)GB, leaving the existing data intact. Create a new partition in the remaining space and format it to NTFS. Save the iso to the new partition.

You need to format the drive in the NTFS format. If you are only getting 3.99GB (~4Gb) then your drive might be formatted to FAT16 which has a 4GB limit. Fat 32 has a 127GB limit.

NTFS has a limit that far exceeds anything we will need in the next 5 years.

I think this is not the problem whether it copies 3.99 GB, 4 GB file might be only is of 3.99 GB but it would be showing you 4 GB, I will suggest you to check whether the file you are copying get stuck anywhere when you run the content of that file, if it is working properly then there won't be any problem, the problem in this arises when you are downloading file from the internet and it copies only certain amount of file size and it does not work. This same issues you could also see in the 4 GB pen drive, it reserves 1mb for its file system, it never copies 4 out 4 Gb It allows only upto 3.5 to 3.8 GB file size.

You need not format to convert from NTFS to Fat32.

You can only copy large files if and only if your hard disk is of NTFS file system.
