- partitioning - What is the difference between LBA and non-LBA IDs . . .
Modern OSes are usually able to determine on their own how a drive is supposed to be addressed Even back when LBA addressing was young, and disks were accessed via the BIOS, it should have been possible to simply probe for the availability of the appropriate interrupt 13h calls and fall back to the CHS version if they are absent The additional partition IDs therefore seem redundant What was
- smart - How to interpret this LBA number? - Super User
0 How to interpret this LBA number? The authoritative source is the ATA ATAPI Specification, which is the basic command set used by SATA devices According to Section 3 1 37 LBA (Logical Block Address), an LBA is the 'value used to reference a logical sector'
- hard drive - LBA and sector size - Super User
7 LBA itself can apply to any sector size, but hard drive sector sizes have been 512 bytes since the start of the PC, and all hardware and software has been hard-coded with that assumption So rather than wait for new systems and operating systems to support 4K sectors, the drive will appear externally as a 512-byte sector drive
- How to move G-List bad sectors into P-List and reassign LBA
Here is the trick…During manufacturing, the layout of the LBA blocks occurs by shifting the LBA block sequence past the “Bad” sector The LBA layer simply skips over the identified “Bad” location in the “P” list and continues sequentially in LBA order
- Linux and Windows report different physical sector size for Intel . . .
I would guess that your disk uses the default LBA Format 0, so it advertises itself as 512 bytes Meaning that the Linux utility you use is entirely right about it However, the Windows utility looks deeper and reports in addition the real physical sector size Both utilities are right, but if the Linux disk driver also allocates disk units of 512 bytes, then performance will be affected a bit
- diskpart - How do select FAT32 CHS vs LBA - Super User
When I try to format a new SD Card with diskpart: format fs=fat32 I always end up with partition ID 0x0c, aka FAT32 with LBA Addressing I tried boot with this but the embedded device is apparently not compatible with LBA Is there a different diskpart command for creating FAT32 with CHS addressing?
- Hard drive LBA Error: How to proceed? - Super User
Well, that, and perhaps wave our hands wildly in the air for emphasis LBA is an acronym for Logical Block Addressing In this case I assume it is just another, possibly more technically accurate way of referring to a "bad sector" Unless your hard drive is very old, the file system of your OS probably didn't even know anything had happened
- How does Logical Cluster Number to LBA translation happen in NTFS?
Yes If we assume traditional drive then no LBA to anything conversion takes place But even if we consider SMR or SSD drives in which LBA addresses are dynamically mapped to physical addresses, from the perspective of the OS nothing changes as that part is handled by the drive's firmware NTFS uses logical cluster numbers (LCNs) as storage
