This could indicate a failing hard disk, or at least a damaged one.

Well, I've not received errors like this while using FreeNAS; however, it looks like it's having a problem writing. The message you are getting says as much.

Upon looking at the code that triggers this particular error,

"// Creating temporary directory to mount CDROM.
if (1 == mwexec("/bin/mkdir -p {$mntpath}")) {
write_console("Error: Failed to create directory '{$mntpath}'!\n");
return 1;
}"
It appears that it is failing to be able to create a directory on the HDD in order to facilitate the mounting of the CD drive, so it's a hard drive write issue you are experiencing for sure. You may try doing a quick format on the drive (if there is no data on it or that you are worried about) and try to do the install again.

It looks to me like you've either got an unusual or damaged hard drive. I would recommend downloading a FreeBSD liveCD (http://livecd.sourceforge.net/) and see how well that boots. Once you're there, try using the disc utilities, and see how well you can mount / partition / format the drive.

That will give you an idea of what's going on in a more interactive environment, and because FreeNAS is based on FreeBSD, you'll know for sure whether your drive works in that OS well.

Bad drive, CRC error=cyclic redundancy check, LBA=Logical block address
Basically the drive is reporting it's failed due to bad blocks. Replace it if under warranty.

Try wiping your hard drive with a free utility called UBCD. Remember to back up all data first!
www.ultimatebootcd.com can be downloaded and burned to a CD
It contains the vendor diagnostic tools and other tests for almost all hard drives.
