Just bought a maxtor 160gb disk and it shows upt as a 137gb disk. I thought this might be the system board's ide chipset limitation so I put a scsi->ide adapter on the drive. Same situation occurs. I'm looking at what the kernel reports when it finds the drive. /proc/partitions shows this drive as:
8 0 134217727 sda
/proc/scsi/scsi shows:
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Maxtor 4 Model: G160J8 Rev: GAK8

I tried kernel 2.4.14 and 2.4.18. Any ideas?

Hi,

There was a thread on this 2-3 months back.
IDE in 2.4 doesn't have a 48-bit block address interface IIRC, although Andre has some patches for this.
This is necessary to go above 137 GB.

Wasn't some of that merged into one of the early 2.4.19-pre kernels?

ERM,

Why is it showing up under SCSI ?

If you are using a 3Ware adapter, you will need to upgrade the firmware to enable 48 bit lba. Ditto other RAID controllers.

True, but some cards will require a firmware upgrade.

It's not on a raid controller. The machine has a PIIX3 ide controller and a AHA-2940UW scsi controller. Both exibit the same problem.
