Hi, I lost MBR and Partition Table values, but I know all the values in LBA. My HDD is 186.31Gb (geometry: 125231 cylinders, 65 heads, 48 sectors): 6 partitions (3 primaries + 3 logicals in extended partition). All partitions are NTFS. I think if I edit partition table with correct entries I can see all partitions again, but I don't know how to translate LBA addresses in right hexadecimal values, because of 48-bits LBA addressing (HDD is larger than 137Gb limit). Example: the first (primary active) partition starts at sector 63 and it's 16595081 total sectors, how to translate this in hex values to entry in first record (01BEh to 01CDh) of partition table? Start sector (3 bytes): Head (8bits), Sector(6bits), Cyl(10bits) End sector (3 bytes): Head (8bits), Sector(6bits), Cyl(10bits) Start offset sector (4 bytes) Total sectors (4 bytes) I don't understand how can I translate 48-bits LBA addressing in 24 bits addressing? The data I lost are VERY VERY important for me. Thank you very much | ||

Simply use the partition table template in WinHex, where you can enter the numbers in decimal. For each partition concentrate on start sector number (LBA) and total number of sectors. You can probably forget about the C/H/S values. |
