Copying a 300 Gig file between two ext. hard drives via laptop

Question

I have two external hard drives and a laptop.

I want to copy a single very large file, which is around 300 GB, from one of the external hard drive to the other.

What is a practical way to do that? Any tool that can help?

Desired features, it would be great if:

• the tool/method can recover from interruptions (I do not have UPS, and blackouts are somewhat likely in the area where I live).
• it were possible to suspend and later resume the copy process (I may not be able to leave my laptop running for 8-16 hours straight, which is the time I expect the copy process to take in real-life).
• there's a realistic estimate of time remaining while copying.

Answer 1

This is not part of the question, but I was wondering exactly how long it would take: USB 2.0 has a transfer rate of 480 MBit/s, or 53.248 MB/s. 300 Gigabytes is 307200 Megabytes / 53.248 MB = 5769 seconds = 96 minutes

This free software reviews great and seems to fit your need:

richcopy, by one of microsoft's local offices does pretty much everything you mention on the list. And yes, the file is called Hoffmansutilityspotlight.

to steal the feature list on that link

1. More powerful, faster and stable than than any other file copying tool.
2. Create several profiles to assign special settings with a specific profile.
3. Copy files from multiple and different locations and save in a single destination.
4. Filter the files based on the date, time and choose to either copy or opt those files.

6. Suspend and resume file copy at any time.
