View Full Version : Recurring problem since OSX update - I/O error

08-26-2007, 05:46 PM
I'm having a recurring problem backing up my mac. One specific file seems to be causing the problem, but I can't find it anywhere on my mac, and I can't seem to fix it.

I use SuperDuper to back up regularly to an external hard drive. I often get an "input/output error" from a specific file on my mac (diff each time), which I easily fix by just deleting the offending file from my mac, assuming the file is corrupted). This usually works fine for me.

But now I'm getting errors on this file:


Which I can't find anywhere on my mac OR on my external HD.

Just yesterday I did an "archive and reinstall" of OSX 10.4.8, and then updated to 10.4.10. I tried erasing the external HD and doing a fresh backup, but today I get the error below. I've tried erasing and reformatting my external hard drive, but I get the same error over and over again. Help?

It could be due to a problem on the destination. Drop me a line at support, OK?
