Hello Guys, has anyone worked with RayScan Before? They were getting this Warning here, preventing them from taking any CTScan. The data is being stored in C:. and this is only 145 GB, and it had only 42 GB free. I had worked on it and could increase it to 51 GB free, but wouldn't it be better to perhaps move the data to a D: drive that is 700 GB and has 698GB free, or to the server, maybe?

@Anthony can consult us about this

Tech B 2025-02-03 21:09

where is the software installed? the server or aqc PC?

Tech A 2025-02-03 21:10

AQC PC!

Tech B 2025-02-03 21:10

@Anthony can this be moved to the server instead?

Tech C 2025-02-03 21:14

I have not done that setup before, so I dont want to say for sure. We would want to get Ray involved since these AQC PC's comes pre configured with the Machine itself.

# Resolve RayScan Alpha disk space warning preventing CT scans

## Problem

RayScan Alpha software (v2.4.4.4 / THU v2.4.2.9.752) displayed a CAUTION dialog stating "The system may not operate properly if the disk space is less than 30%." This warning prevented CT scans from being taken. The system was storing data on the C: drive (145 GB total) with only 42 GB free space remaining. A larger D: drive was available with 698 GB free out of 700 GB total capacity.

## Resolution

1. Free up space on the C: drive as an immediate workaround - in this case, space was increased from 42 GB to 51 GB free
2. For a permanent solution, contact the vendor (Ray) before attempting to relocate data storage, as AQC PCs come pre-configured with the CT machine
3. Do not attempt to move RayScan data storage locations without vendor consultation, as this could affect the integrated hardware-software configuration

The immediate disk cleanup resolved the warning temporarily, but vendor involvement is required for any permanent data migration solution.
