HD has support

[rebom]

hi, i would like to know if a hd has support for LBA48 what does it mean?
as in the image in the text at the top right
Thank you[ATTACH type=“full”]9169[/ATTACH]

The information in the image you suppled is not a hard drive it is a compact flash driver.

What is the issue that you are having with the flash drive?

https://www.linuxquestions.org/quest...-lba48-174457/
48-bit Logical Block Addressing (LBA) extends the capacity of IDE ATA/ATAPI devices beyond the limit of 137.4 GB. This limit applies to IDE ATA/ATAPI devices only and not to SCSI interface devices. The original design specification for the ATA interface only provided 28-bits with which to address the devices. This meant that a hard disk could only have a maximum of 268,435,456 sectors of 512 bytes of data thus limiting the ATA interface to a maximum of 137.4 gigabytes. With 48-bit addressing the limit is 144 petabytes (144,000,000 gigabytes).

The kernel, motherboard BIOS and the IDE controller needs to support LBA48. AFAIK the 2.6 kernel shouldn’t have a problem with LBA48.

yes maybe English is not my strong point, but I understand that it speaks of hd higher than 137, but what does compact flash have to do with lba in question?

[Rustys]

Nobody knows what is meant by certainty?

Meaning for the the LBA48? answer in previous post.

[rebom]

yes i had seen the thread, and indeed it explains a lot, but it doesn’t clarify about the 64gb cf card

Basically, it is just the way the system counts the sectors for storage devices.

see if this put it into perspective

https://en.wikipedia.org/wiki/CompactFlash

CompactFlash IDE mode defines an interface that is smaller than, but electrically identical to, the ATA interface. The CF device contains an ATA controller and appears to the host device as if it were a hard disk. CF devices operate at 3.3 volts or 5 volts and can be swapped from system to system. CompactFlash supports C-H-S and 28-bit logical block addressing (CF 5.0 introduced support for LBA-48). CF cards with flash memory are able to cope with extremely rapid changes in temperature. Industrial versions of flash memory cards can operate at a range of −45 °C to +85 °C.

I have read everything but I did not understand if this cf card says that it has lba48 support, understood as being recognized as an lba48 or not? (hd higher than 137 gb)

[Rustys]

Yes it can be if they system that it is being used in can.

[rebom]

I bought one without asking myself too much, then I legitimately had doubts

[Rustys]

With the advancement of technology some of the old information like that is no longer valid.

[rebom]

become obsolete I would hope not so quickly

[Rustys]

Things do get obsolete over time.

Is there anything else covering your initial post we can assist with?

[rebom]

I think I’m okay with that. Thank you

[Rustys]

any time

Happy computing
