Siz, there are several documented problems with the 1541 ROMs. Save with replace bug. Buffer allocation bug. Block-read and block-write commands (B-R and B-W). Block-Allocate sometimes allocates a whole track instead of one block. Reset command bug. (Source: Inside Commodore DOS, pages 206-208)
Also, many 1541Cs do not have the track 0 sensor functional as shipped from the factory; the user had to disassemble the drive and attach it. Commodore later removed it from the specifications altogether.
