I've been reading the thread about backing up hard drives with interest. I have a similar question. I have a 4 TB external USB hard drive that I've been doing backups on. Unfortunately, it's starting to get a little flaky -- not being recognized by my laptop, etc. The problem got better when I changed enclosures, but now I'm a little paranoid that it might continue to degrade. So... I'd like to copy the data to a new USB external hard drive. The drive is about 96% full. I have tried plugging the old drive into a USB port, plugging the new drive into a USB port and simply doing a cp -Ruav from one to the other. It goes gangbusters for awhile, but after about 5 or 10 gigs, it slows down to almost nothing. At the end of 8 hours of copying, it's plugging along, but I only have about 400 gigs copied. I've searched the intertubes, and it seems that this is a problem people have asked about across multiple distros. It is apparently associated with some sort of cacheing issue in the kernel. Is there some solution to this? I tried rsync, but it was even slower. I haven't tried dd, which was mentioned in the other thread; I might give it a shot this weekend. But if there's a known fix for this, I'd love to hear it.
