Is USB2/Firewire enclosure independent of computer BIOS?

Archived from groups: comp.sys.ibm.pc.hardware.storage (More info?)

Hi,
I've been discussing some external enclosure problems here and
elsewhere recently. These have been mainly related to the full
capacity of large hard drives not being recognised when used in some
enclosures.

Some clearly knowledgable people here have indicated that the case
electronics are often deficient where large HD's are concerned,
particularly for USB2 .

In attempting to resolve the problem with the case supplier, there has
been a tendency on the supplier's part to fault the computer BIOS.
So, I tried the external case on 2 other PC's that had no trouble with
large internal HD's and the same problem occurred.

To help establish clearly where the fault lies, can anyone please
explain what role, if any the computer BIOS has in running hard
drives fitted in this type of external enclosure?

Regards,

    Your system BIOS only supports the IDE&SCSI adapters on the mainboard.

    The USB/Firewire chipset&firmware in the enclosure is the only thing that can
    impose a 137GB limit.

    Thanks, I did get the distinct impression that this was so from your
    previous explanations. I just wanted to confirm it to support my
    response to the suppliers stance on the matter.
