Hi and thanks,
This is about trouble reading files from a particular partition. The volume is my home directory from the prior (now deleted) Fedora 9 system. Linux doesn't list the partition in /dev/disk/by-uuid. When I try to fsck it, I see a report that there are problems and a check is forced. Then after a while fsck asks to make some changes and after making them it seems to finish successfully. But when I mount the volume there is gibberish for file names. Now the first time fsck reported errors I was surprised. The drive had been closed down properly I thought and had been working in the prior system. So I booted Knoppix and saw similar gibberish when the partition was mounted; and I ran fsck there for the first time. It forced a check and when it was done, I mounted the partition and all the file names appeared. But when I mounted it in the new distributions both had the problem as described above. When I reloaded Knoppix again, the files were there without fsck.
Originally I was running Fedora 9 and decided to try Fedora 10 and Ubuntu 8.1. Also I've reinstalled Ubuntu 7.1 which I used before Fedora 9 and the same problem appears there. So Ubuntu 7.1, 8.1 and Fedora 10 have problems with the partition but not Knoppix??
My hardware is an Asus M2n-SLI. It has the nforce 570 chipset. Lspci reports it as MCP55 SATA controller. This board also has a JMicron 20360/20363 hot-swapping controller and I've gotten the problem with both. The hard drive is a SATA I Maxtor-Maxline III Model 7L300S0. The drive is in a Supermicro hot-swapping box.

Why does fsck know /home/antbat?
Hoping you can help with this. Thanks!
