We live and die by hard drives for music. There’s no substitute for redundancy and backups (hey, you could be Matthew Dear and have a drive stolen during your set). But it is helpful to know whether a drive is healthy or not. S.M.A.R.T. monitoring features built into drives can help.

Lifehacker today points to a free Windows utility for the job called CrystalDiskInfo:

CrystalDiskInfo Monitors Hard Drive Health and Uptime [via gHacks]

But that got me thinking about other tools. There’s quite a range of choices for Mac, Windows, Linux, and even some obscure operating systems. The only bad news: generally you’ll only be able to monitor internal drives, unless your external drive is eSATA rather than USB or FireWire. (eSATA is where I’d like to go generally – it’s quite a lot faster, and frees up your USB and FireWire buses for other things — but that’s a discussion for another day.)
