I have an external Hard Drive that I leave turned on all of the time. I recently heard that external HD's are constantly spinning when turned on. Is this true? It seems like a lot of wear and tear on the HD.
Just a few weeks ago I had the HD in an external HD crash, I'm wondering if this might be some of the cause.

Thanks,
JTN

All hard drives are usually spinning all the time. That's one reason that they access data so much more quickly than CD-ROM's--they don't need to "spin up" to get up to speed. The exception would be if you had settings in Power Options to shut down the drives after a certain idle time. They are designed to withstand this usage, but just turn it off when you are not using the computer.

Before the days of reliable shutdown options, I had hard disks that ran for years. This is not a significant issue. However, I also recommend turning off externals when they're not in use, since another issue is heat buildup in the small external cases. I have four NAS drives here, and all of them have auto-shutdown after a period of inactivity. They stay on 24/7, and run quite cool. The measured power usage when they're powered off is from 7-10 watts, but it jumps up to around 25 when they're spinning the drives and accessing data.
