Hey, I'm new here, so sorry if I leave any important information out. I'm on a 13.3" MacBook Core 2 Duo 2.0 GHz 2 with GB RAM that's around 7 months old, running Snow Leopard. Lately (past week or two) I have had a lot of trouble using Finder, getting the 10810 error that a lot of users have been experiencing. If I am copying a large file (more than 1 GB) or if I have just attached an external hard drive, sometimes the beachball starts going and it won't quit. Relaunching finder is unsuccessful. I've had to use a hard restart 3 times recently because nothing else will work. Since Finder was giving me so much trouble, I decided to run OnyX. OnyX told me that I needed to repair my hard disk, which sent me into extreme panic and a Google Search frenzy. From two threads (http://forums.macrumors.com/showthread.php?t=359837 and http://forums.macrumors.com/showthread.php?t=614295), I'm thinking that things will probably be okay (fixable, no lost data), but I'm still pretty worried since this is my precious MacBook we're talking about. I made sure all my data was backed up, and then I used Disk Utility to verify and repair permissions. Then I verified my disk, coming up with these error messages: Missing thread record (id = 1098151) Missing thread record (id = 1293146) Missing thread record (id = 1303328) Invalid volume file count The volume [Hard Drive Name] was found corrupt and needs to be repaired. Unfortunately, I can't repair the disk right now, as I don't have the Snow Leopard disc on me at the moment. I did run SMARTReporter, and everything looks good--no eminent failures. So for my questions: 1. If I run Repair Disk with the Snow Leopard disc, will things most likely be okay? Will I experience any data loss? 2. Is there anything I can do other than Repair Disk or after I Repair Disk to help fix things? 3. Any idea why this is happening? (I like to understand the situation so I don't repeat anything I did wrong) 4. Is it okay to keep using my computer until I get this fixed, even though a corrupt hard drive seems like a pretty big problem? Everything seems to be running smoothly, other than the occasional bug with Finder. Thanks in advance for your help, and let me know if you need any more information.
