Yes, I completely agree that the different sector sizes can cause confusion, so I'd rather check the designed capacity vs the addressable capacity (sector count multiplied with sector size). Reports in such situations always helpful. If their contents are equal, the misadressing occures. Traditionally, older drives 2TiB HDDs not supporting can only be detected in a safe wayīy reading maxLBA and MaxLBA&(log.ANDed with)0x0000FFFFFFFF sector. It would also be nice to show at the HDS reports the logical sector size, DCO and HPA size (if supported and set) and whether offset mode is active.Īdditionally, another thing can influence sector count: Jumper - and this would also be worth to be adviced by a warning. In this case the # of sectors shown by ID cmd is 1/8 of the nominal value relating to 512byte sector size. This might be influenced by logical sector size (normally 512, but meanwhile most of the external disk drives the USB3/SATA bridge controller emulates 4096 as logical size) and can be evaluated by the ID cmd returns. Nominal sector count (MaxLBA) of a drive model can be retrieves from Database. ![]() OK, next time stumbling upon such a problem I will instruct the user seeking for help to do so.Īfter a short meditation I found this is a little bit more complex. ![]()
