5 Tips for Audio Recording Hard Drives

Hard drives are hard.

You want to record audio in the modern age? You don’t have a Zildjillion dollars to be able to record to tape? Even so, it all ends up digital. You need some hard drives.

Five Audio Recording Hard Disk Drive Tips

Hard disk drives aren’t all the same. Picking out the right one can be tough. Here are some things I’ve learned — sometimes the hard way.

1. Heed the DAW makers’ suggestions.

If AVID says that Pro Tools doesn’t support it, don’t expect it to work. Legit DAW makers will post the system requirements for their software/hardware. Look them up. Follow their recommendations and instructions. Spoiler: You’re probably going to have to spend more than you had planned for.

2. Faster is better.

A faster drive means it read/writes faster. And faster read/writes means more tracks and/or higher quality.

Traditional hard disk drives have platters that spin. A hard disk drive that spins at 5200 rpm really isn’t fast enough — it’s like red-lining a Geo Metro. 7200 rpm is better. 10,000 rpm better still.

And then there’s flash drives, which are way faster than hard disk drives.

There are also seek times to consider, for which lower numbers are better. Seek time is the baseline amount of time in milliseconds that it takes for a drive to fetch data.

I have found that drive manufacturers don’t always make these stats readily available. When in doubt, assume the drive doesn’t meet spec (because it likely doesn’t).

3. Data interfaces matter.

Hard drives have come with lots of data interface flavors: PATA, SATA, USB (1, 2, 3), FireWire (400, 800), Thunderbolt, Ethernet, and some are even wireless. The data interface dictates bandwidth, which roughly translates to how many tracks you can record at once and how much latency your playback will suffer. More bandwidth is better, which translates into better recording and mixing experiences. Again, check your DAW maker’s system requirements and choose the drive with the fastest and most forward-compatible data interface.

Also make sure your computer can handle the data interface type you’re choosing. And find out if the data port you intend to use on your computer is sharing a bus with any other peripherals in your computer. That can adversely affect your bandwidth, causing a data bottleneck.

4. Bigger isn’t better.

For tracking and mixing, you don’t necessarily need a 3 TB drive. (Unless, of course, you’re recording a 10-piece prog-rock group with 40 minute “works” at 32-bit 192kHz.) Save the big, slow drives for backups and archiving. Use smaller, faster drives for works in progress. If you have more than one project going at a time, consider using a small drive for each project, so the different project files are not interleaved with each other on the drive. This will speed up read/write times, as the drive will not be jumping around on the platters trying to find the files for the current session. This also saves money, since really fast and really big drives are expensive.

5. Always have a backup.

Have a backup plan, because hard drives fail. All the time. More so than any other part of a computer. Make sure to always backup your work after every session, whether recording, editing, or mixing. And make sure you have an extra drive ready in case one goes down during a session. I can’t stress this enough. Millions of ones and zeros (i.e. your priceless recordings) can go poof at any time — and there’s never a right time for that. Buy more hard drives. Make backups like a chronic. Sleep well.

FIX: Pro Tools An unexpected authorization error 14051 occurred.

This might be the solution.

An unexpected authorization error 14051 occurred.
ID: ePAY : 14051 / Dngl : 1595

I got this error a few days ago. It’s a new one for me. What caused this? Good question. I have no idea. Pro Tools wouldn’t really start after this.

As usual the Avid forums weren’t very helpful. Which led to this tweet…

For the record, at the time the error occurred I was running OS 10.8.4 and Pro Tools 9.0.6 on a Mac Book Pro with an iLok 2.

The Fix

I had to force quit Pro Tools. Then I unplugged my iLok 2 and plugged it into a different USB jack. Presto. Working again. Not sure what caused it, nor if switching USB jacks was actually the fix, but I did get it working again after doing so. Hope this helps somebody.


I confirmed again that switching which USB jack the iLok 2 was plugged into made the difference. I would think that this is a problem with that particular USB jack, but all other USB devices work just fine plugged in there. Hmm…
