I have 10.6.5 and for the past few weeks it seems to intermittently lose the ability to transfer files to any external drive. It's acting like the boot drive is developing bad sectors...clusters..whatever, it's acting like the harddrive is killing itself, but I've run every test I can on it, and they all come up clean, I've run applejack a few times when I've encountered the issue....no real issues there except it reports a few permissions being incorrect on a bunch of java stuff...
What happens is, I'll transfer a bunch of 16kb files to my flash drive just fine (torrent files) and then when I try to copy the downloads, sometimes it'll get to 62MB, sometimes it'll get to 10.2MB...sometimes 365MB...it's different per file, but once those transfers fail, the original file on the boot drive becomes unusable so I end up having to download it again on another computer. This issue is really annoying mostly because nothing is reporting any problems when I run system self-checks, and something is clearly incredibly broken, and nothing seems to be correcting the issue.
My current plan of action is to just reinstall OS X, but.....this isn't something I've ever had to do with a mac before, only windows machines.
Is 10.6.5 just incredibly awful, and introducing really unstable code into the OS? I've seen OS X do some weird things, but this is weird like....they've just given up on testing their code before release-type of weird.
Any pointers?
