FDC error retry

I want to add a read/write retry to my FDC software on my 8080 CP/M 2.2 machine. I'm using a 8272 FDC chip. The read command will return these errors should they occur;
1. Sector not found, Status Register 1 Bit 2
2. CRC error in ID field, Status Register 1 Bit 5
3. CRC error in DATA field Status Register 2 Bit 5
I figure that these errors are 'soft' errors and are worthy of a retry. Is my thinking right here? The other errors that the 8272 finds seem to be related to equipment or other stuff. Comments? Thanks Mike
