Okay, what's the deal here....why doesn't CHKDSK, even with additional attributes added, work in repairing disk file problems. I have 2 SATA's added to my system, and both are additional storage only at the moment. I'll switch over to installing the OS on one later. For now, however, I only want to convert them both to NTFS. For some reason they've both begun to deny my access to certain folders, with the system rendering the following error message "The file or directory is corrupted and unreadable." The names of some files and folders have become truncated; and not all have long path names so I doubt that's it. I'm at a loss with this one... Is there a utility someone could suggest, or know of something else I could try? I'd appreciate it. I also own SpinRite - Steve Gibson's awesome HD recovery utility - but I don't think that applies here to this sort of problem. Thanks greatly in advance! Eis!
