You need to check for the inode which identifies the file and its attributes on a file systems using the following command: $ df -i
$ df -i /ftpusers/ Sample outputs:Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda8 6250496 11568 6238928 1% /ftpusersSo /ftpusers has 62,50,496 total inodes but only 11,568 are used.

The first page is never mapped, so it's ok if you read the file sequentially, but not suitable for a database process that seeks directly to the middle of the file.
On Linux, here's a method that doesn't require any prior setup and generates an unusual error (not EIO “Input/output error” but ESRCH “No such process”): cat /proc/1234/mem where 1234 is the PID of a process running as the same user as the process you're testing, but not that process itself. http://www.cyberciti.biz/datacenter/linux-unix-bsd-osx-cannot-write-to-hard-disk/ Sign In Apply for Membership Categories All Discussions4,369 Uploadify ↳ Implementation Help - Uploadify3,124 ↳ Bugs - Uploadify738 ↳ Feature Requests - Uploadify195 ↳ Showcase - Uploadify74 UploadiFive ↳ Implementation Help - UploadiFive133 ↳ Bugs - UploadiFive66 ↳ Feature Requests - UploadiFive33 Sorry...
