Default Transferring 250GB of data

One of the external HDs is almost full (about 240 GB) so I bought this external HD to, back it up, also to use the remaining ~250GB. My question is, is it OK to transfer the whole lot in one go. Kindly keep in mind that both have fans for cooling.

While we are at it, any thoughts on the Buffalo drive linked above.

Thanks

Copy it over rather than "moving" it. If something goes wrong, you've got the original still and can do it again.

Test random files after the copy. Once it's verified, go ahead and delete the original data.

Personally, I do it in chunks. If the copy fails, you're never quite sure where it stopped in Windows. You can manually compare but it's a pain in the butt.

I use Buffalos at both home and work. No issues but you should realize that it's NOT a Buffalo drive inside. It's whatever they want. Not sure what the flavor of the month is now.

Cheers, Brian

My first question is about copying the 240GB in one go, meaning the whole amount in one copy operation. Is that OK? Copying (not moving) in chunks will be very messy for me, hope to avoid it.
Btw, why would I delete the source, the whole idea is to back it up.

As for Buffalo...ouch. Hope they put something decent in this one.

use a program like allwaysync.
It can do the whole lot, but it keeps checking ifr there are no write errors.

Trying to move it in 1 big lump sounds scary. Besides probably taking forever, with windows there are so many chances for the files to corrupt along the way.

Any reason you wouldnt just burn them to dvd's? (the large 9gb size if you can)That way they are truly backed up. Just pick up a stack from a store like bestbuy and slowly transfer them to disc for security?

I know, I'm very nervous about it. That's why I'm asking the experts here.

DVDs? Ouch. 240/4=60. That's 60 DVDs to burn. That's not feasible, imo.

Thanks Douglas for the suggestion. Oh, and have a karma on me.

For starters in Windows XP or even Vista if you start a transfer for 240gb and there is like what 100,000+ files or 500,000 (I forget how much files) windows starts the initial transfer by doing something that seems to take for ever. ie preparing to start copy, if I recall what it says. Also it will 100% fail at some point and then you will waste hours figuring out where it stopped so you can continue.

So I recommend one folder tree at a time assume of course that all your 240gb are not in one tree.

I usually transfer like 1-10gb at a time only.

NOTE: if you are trying to backup the 250gb drive (external) you may want to try a cloning program that makes a mirror copy of the whole drive onto another drive. It should be faster then doing a file-by-file copy using windows copy/paste or Copy-To-Folder

"Transfer" is not a backup. "Transfer" is a move.

If you're just backing up, ie not going to use the data actively, use a backup utility, a sync utility like Rense mentioned, or ntbackup (included with Windows 2000, XP, Vista, etc..). Set it to back up and verify. You can let it run overnight with no problems.

No issues with my Buffalos. I would think you'd be fine.

I'd look at using rsync for that number of files and volume of data. you can always stop and start and it'll pick up where it left off if you have any problems.
