I am using Vaaman Vicharak, and I have connected an SSD using the VAAMAN SATA HAT. After powering on the device, the SSD is sometimes not detected. The red LED on the SSD keeps blinking continuously, and the read/write LED remains off.
After restarting the device multiple times, the disk eventually gets detected. Based on my observation, when the board has been powered off for a long time and then powered on, the SSD is not detected on the first boot attempt.
