There used to be a cool utility called OOLED which used to display the activity occurring on different drives/drive partitions. Anyone know where I can find it or any other software which does the same thing?

+1. I liked the nice touch of allowing to set a minimum bp/s threshold for disk activity. – A Dwarf Oct 4 '09 at 14:13
Be aware, does not work when performance counters are disabled. Program will loop into error message. – Erwinus Feb 14 '15 at 5:58

DiskMon, which is part of the Sysinternals suite (semi-official Microsoft software), is quite a nice tool.

DiskMon is an application that logs and displays all hard disk activity on a Windows system. You can also minimize DiskMon to your system tray where it acts as a disk light, presenting a green icon when there is disk-read activity and a red icon when there is disk-write activity.

See DriveGLEAM:

DriveGLEAM is a fabulous hard drive utility which shows read-write activity for your hard drives in the system notification area (tray). It also supports output via parallel port so that you can for example have a red led for write and a green led for read access. Features: Monitor physical disks or partitions (or both), Allows for CPU, RAM, VRAM usage display in tray. Read / Write / ReadWrite and Idle status indicators, Indicators in tray or the parallel port, output directly to LED's, Just place some LED's on top of your monitor and enjoy real monitoring of read/write status realtime ;) (no special hardware required), Uses very few resources (cpu usage). Does not "hook" into your system. Failure in DriveGLEAM can't "freeze" your drives. Configurable start with os delay. Configurable poll rate.

You could try gkrellm, which supports this feature and many more.

I’d like to recommend Moo0 System Monitor. Besides other things this program monitors various HDD stats too.

This program allows user to customize the look of the interface freely.

I moved the main stats window on my taskbar. Here’s how it looks:

You can enable auto hide function, so when you move a cursor over the stats meter it disappears and reveals the taskbar. When you remove the cursor from the taskbar area, the stats meter is showed again.

Moo0 System Monitor is highly configurable, but it takes a little time to understand how to customize the program for your needs at first.

I think it’s worth a try.
