The Problem:

For a couple months now, my girlfriend has been receiving Disk I/O errors on Skype that cause the application to crash. She has tried quite a few solutions available online, but none have rectified the problem.

Interestingly, the crash does not occur on login, as many users have reported, but seems to occur sporadically, happening a few times in a day before disappearing altogether for another week.

The error itself looks like this:

Disk I/O Error

Is there anything else that can be done to stop this error and the resulting crash?

Things we have tried:

  • Restarted Skype

  • Restarted Computer

  • Uninstalled and Installed various versions of Skype including 4.2, 5.6, 6.1, and 6.11

  • Tried deleting all user files following this guide.

  • Tried deleting user files, and rebooting

  • Tried deleting user files, uninstalling Skype, and rebooting

  • Tried deleting user files, uninstalling Skype, deleting the entire Skype folder under appdata/roaming, and rebooting

  • Tried running Skype as administrator as per this answer

Additional Information:

We also tried running CrystalDiskInfo in the case that it might shed more light on the computer's hard drive itself. The info may not be pertinent, but here is a screenshot of all the information:

And the text copied from the program:

Note: I will update the question with a log file from Skype when I have one. Till then we have to wait for a crash as it can't be reproduced and we only just enabled logging.

    run chkdsk /F to detect and repair NTFS issues. Does this fix it? – magicandre1981 Dec 13 '13 at 5:04
  • I assume you have contacted Skype customer support as instructed in the message. What did they say? – user261217 Dec 13 '13 at 6:57

The first thing to do when there is an I/O problem, is to run a thorough disk check, including a scan for bad sectors.

There are more strange behaviors. Something is wrong with Skype.
