Just a heads up.
I'm running Ubuntu Server install 9.0x (x64) and I was getting the following problem.
I tried running HDsentinel with:
but it gave the following error message:
"sudo: Unable to execute ./HDSentinel: No such file or directory"
Seems you need some x86 libraries to run HDSentinel on a 64-bit OS.
$sudo apt-get install ia32-libs
This will install 142 MiB worth of x86 libraries HDSentinel needs to run.
After installing HDSentinel works like a charm.
A 64bit recompile would save us some space
