I'm copying a 31GB folder of pdf books from my hard drive to my 2gb Hitachi USB 2.0 external drive. I did a copy n paste of the whole 31gb folder to the Hitachi. Boy is the file transfer too slow! The info screen says it's transferring data 875kb/sec - that it'd take me 1 to 2 days to transfer everything!
Anybody else experience slow backup on USB 2.0 external drive? How did you ever make file transfers go faster. Transfer smaller folders step by step to be faster?
So its a lot of little files? That'll kill your speed. Try copying a single big file, timing it, and doing the math. You should get around 20MB/sec if the drive and everything is working up to spec.
I'm assuming you mean zip or rar all the pdfs to one file, right?
He could zip them all into one or more big file before transferring, but that would take a while too. What I want to see is how fast the drive is transferring any large file to determine if the drive itself is working OK. Another tool I use is a program called HD Tach wich can be downloaded for free. If a drive test out abnormally slow, I know there's a problem.
Oh yeah, my mistake - it's a 2 TB Hitachi drive. I'm copying 13,830 items [mostly pdf] from my hd to the Hitachi, and it's getting slower as time goes by. Now it's at 791 kb/sec - 9151 items to go.

The other thing is I think PDF are highly compressible so that 31 gigs over 13800 files can be converted a 20 gig single file. May be a lot faster.
Utilize a multithread file copy util like Richcopy for best results. I've never used it but I hear it's much better than robocopy which is my tool of choice, next large file copy I have to do I'm going to give it a shot and to compare to robo. If you have multiple files or large files to copy you should never use the built in copy tool, it doesn't offer restarting/bit level comparison/and is just slow.
What OS are you in? If it's XP, it will work at an absolute snail pace with the new advanced format drives.
