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
  Type: Direct-Access ANSI SCSI revision: 02
     
I tried kernel 2.4.14 and 2.4.18. Any ideas?
