Then use Disk Utility or another robust disk or volume repair tool like DiskWarrior to check the drive for errors and attempt to fix them.
Any corruption in the table could prevent files from being located because this table is used to convert the filenames to upper case when searching to locate a file. Post them below or e-mail us!
Unfortunately even though there are third-party drivers and workarounds to allow OS X to write to NTFS drives, these features are not supported by default, so such drives will only be mounted read-only.The exfat-utils package also contains a “mi-centre.com” command.
