"A disk read error occurred" and its causes

You’ll face a lot of problems and errors when using Windows or any other operating system; nevertheless, there’s always a way to fix those errors. This particular Windows error “a disk read error occurred press ctrl+alt+del to restart Windows” does not display alongside an error code, and it leaves you with a full-blank screen. When you see this message, it signifies that your HDD has stopped working fine.

How to fix it


Method 1: Check hard disk SATA and power cables

When your hard disk cables are bad, it could cause Windows not to read the hard drive; hence, you see the message “A disk read error occurred.” So, you should check and possibly change the SATA cables, plus the IDE power cables, too. A multimeter testing device can be used for this check. If your PC runs with dual hard disks, disconnect the second one and leave only the one that has Windows installed on it.

Method 2: Run a memory test

Sometimes, this error message appears due to memory issues (RAM). Although this is a rare case or if you recently installed a new RAM on the computer, running a memory check can be of help in this situation.

If you added a new RAM, simply remove it and restart the computer with its primary RAM. Also, if your PC has multiple slots for RAMs, try switching your RAM module in different slots and restart your PC each time you change the slot.

Method 3: Fix MBR and run Bootrec

Another possible way to fix “windows disk read error” is by using the built-in Window utility for fixing boot records. If the Master Boot Record files are corrupt and the reason why you’re seeing the “disk read error,” then you can fix it with the steps below.
