The following article troubleshoots in the event that a "ERROR! Card Busy", "ERROR! Card Read" or "ERROR! Card Write" message appears.
- The CF memory card may be fragmented. Follow the steps in the article below to defragment the CF memory card:
BR-864: SYMPTOM: Receiving "ERROR! Card Busy, Card Read or Card Write" Message - Be sure that the CF memory card being used is compatible:
BR-864, BR-600, BR-900CD, BR-900: Compact Flash (CF) Card Compatibility Guidelines - Be sure that only a BOSS PSA-120S or PSA-120T power supply is being used. 3rd party power supplies can cause the product to not operate properly:
https://www.boss.info/us/products/psa_series/ - Try a different compatible CF memory card. Note that most manufacturers of Compact Flash (CF) cards stopped producing this type memory years ago and we no longer have a resource for where to acquire one unfortunately.
- If the problem continues, there may be an issue with the BR-864 unfortunately. Due to the age of the product and the fact that parts are no longer available for the BR-864, our service department no longer services these. You may try contacting a local service center here:
