Major I/O write bytes on the Spotify Desktop app. It will kill SSD drives in record time (fixed)

Status: Closed

EDIT: According to Spotify this issue has been fixed in the 1.0.42 version so the case has been closed. Personally I have no more issues with this anymore on any computer. Thanks everyone for making this happen !!!


original post:
Major disk write activity detected on the Windows/Mac app. Does not behave like that when using the browser player.

Please look into this thread, more details there:


Attached readouts from a Win7/64 PC during one hour and ten minutes. No offline playlist syncs and zero songs were played during that hour, only the spotify app tray active in background!

No disk drive, SSD or standard HDD can take that rate for a long period of time.




Thank you for bringing this issue to our attention. As some of you have noted, the prior version of the Spotify desktop client may sometimes have caused unnecessary data to be written to storage devices. This issue has been fixed in the current version of the desktop client (1.0.42), released November 11th, and rolled out to all our users. If you try to run an older version, you will see it automatically restart and update to the new version shortly after you log in.
If for some reason you should encounter problems with the auto update, just follow these steps to perform a full reinstall.

If you're running a deprecated OS (Windows XP, Vista; OS X 10.7, 10.8), don't worry. A fix has automatically been rolled out to you too. To ensure you're running this version, just close/reopen the desktop app twice.

Again, we greatly appreciate your help here, and hope that you will continue to flag issues for us when they arise.

You can use Process Monitor by Sysinternals to exactly see what Spotify is doing with your hard drive.


Now you event get bad publicity because of this bug:

Please FIX THIS!

No reinstalling will not fix it! At first it may seem better but it gets worse with time. Problem is that as you use Spotify the mercury.db is growing. Since for some reason it appears that every 5 min the db gets rewritten, the huge data writes will come back eventually.

You can try to change the 'VACCUM;' String with a hex editor.

On macOS it is located in /Applications/

Windows it is inside the libcef.dll

As suggested in this thread

I just cancelled my sub, maybe they have to learn it the hard way

No heavy usage on Android 7. I used simple system monitor to get these information. Please confirm, that this is no but on Android.

The MOST ignorant company ever. I am paying you for frying my SSD and I have to fix it with a F**** HEX EDITOR?!


Deleting this bull**bleep** from every computer in our family & canceling the family subscription. 


Keep it up!

We've seen some questions in our Community around the amount of written data using the Spotify client on desktop. These have been reviewed and any potential concerns have now been addressed in version 1.0.42, currently rolling out to all users.


I can't reproduce this issue... did this get fixed already?

my spotify writes about 3MB/Song according to process explorer, not really much actually.



It has been almost half of a year since this problem emerged. Unfortunatelly I still encounter those issues. I am sorry but I am swithing to Apple Music.
