It is possible that your DVR+(CM-7500) has suffered an operational failure. You can watch live TV but you will not be able to record programs, watch existing recordings or pause/rewind/fast forward live TV.
Please try a power cycle on your DVR+ (CM-7500). This will start a recovery process on the DVR+ storage which may cure the problem. To execute the power cycle you'll want to remove the power cord from the back of the DVR+ or the wall outlet(which ever is easiest to access) for 10-15 seconds. Then reconnect power, and allow the DVR+ to boot back up to live TV.
After the power cycle has completed and your DVR+ is back at Live TV, if you are still seeing the same error message please run a Check Disk on your DVR+. Navigate to Menu>DVR>DVR Setup>Check Disk. Once you select that option Check Disk, allow the DVR+ time to complete the check and see if it completes successfully or if it runs into an error. If it completes successfully and does not give an error message please skip the steps below and test/use the device as you normally would. If the error goes away you can continue using the DVR+ as you normally would. If you continue to see the same error message please complete the following steps below:
Please Re-initialize the storage of your DVR+ by going to Menu>DVR>DVR Setup>Re-Initialize HDD>OK to confirm.
NOTE: Re-Initializing the DVR+ storage will result in loss of ALL currently stored data.
If you continue to experience the storage error, please continue troubleshooting below.
Default Factory Reset
1. Please disconnect your External hard drive and Wi-Fi adapter prior to the default factory reset. (If you are using one)
2. Next you'll perform a default factory reset by navigating to Menu>Settings>Factory Reset>Default Factory Reset. This will erase your personal settings, series schedules and passwords. This will not erase your previously recorded programs, though they may have been lost in previous steps.
3. Follow the on screen setup wizard and allow it to boot-up to live TV.
4. Now you can reinstall your External Hard Drive.
5. Now you can reinstall your Wi-Fi adapter and begin using as normal.
If you continue to experience the storage error, please continue troubleshooting below.
Testing your Internal/External Storage
You can not perform this test if your DVR+ is currently recording or you are playing back a recording.
1. Please navigate to Menu>Settings>Technical Info>STB Health. Once you are in the STB Health window, press the number buttons 3, 1, 7, 9 and you'll see a diagnostic screen appear.
2. Select DST Short Test and the test will begin shortly--displaying blue and red light on the front of your DVR+ while testing. You will also see the DVR+ screen during the test, and once the test has complete, the DVR+ front panel light will either blink blue or it will blink red (Pass or Fail). If you see blinking red this indicates the storage has a problem and will not operate normally. You will need to unplug from power to end the DST. The test results are also documented in the DVR+ internal log.
Recommended Storage for use with DVR+
If failed and out of warranty, you can use an external hard drive by connecting it to one of the USB ports at the rear of the DVR+. This is the replacement storage that we currently recommend, and we cannot recommend anything over 2tb in size.
