2nd hard drive BIOS capacity recogniton

Sony / Pcv-rz32g
October 5, 2009 at 19:35:34
Specs: Windows XP
I added a 40G Maxtor D540X-4K (from a Tivo) as a second slave drive in a Sony Vaio desktop. The BIOS is only seeing the drive as having 10Mb capacity. I can't edit the drive size in the BIOS as it's ghosted.
Any ideas? Thx.

"I can't edit the drive size in the BIOS as it's ghosted. "

You can't edit the drive size in the bios yourself in any case. The bios detects the total size of the drive whether it has data on it or not, if the drive detection settings are correct.

If it's the Sony Pcv-rz32g you installed the drive on, it would not have a drive size limitation bug in the bios version that would prevent the 40gb drive from being detected as it's full size - it came with an 80gb drive.

Go into the bios and make sure the connection the drive is connected to is set to Auto detect by the method Auto or LBA.

Make sure you have the jumper set on the drive correctly:

I had that same problem with a Tivo drive in a PC. I think I just assumed it was bad and set it aside. If the above doesn't work you might consider a low level format. It's kind of risky with a drive that large but since the drive is unusable as is I guess you have nothing to lose. If you need it, I uploaded a version of disk manager which has an LLF here:

I paid for and downloaded the software without reading the notes and now have to find a Floppy Disc. Who knew that when I actually need one of them I can't find one anywhere! Will revert once I find one.
