I'm CC'ing linux-ide... looks like the disk which you say is 20GB is misdetected by the IDE layer as being 2GB. Ok, so we have: > >> Probing IDE interface ide0... > >> hda: WDC WD800JB-00FMA0, ATA DISK drive > >> hdb: IC35L020AVVN07-0, ATA DISK drive > >> hda: Enabling Ultra DMA 4 > >> hdb: Enabling Ultra DMA 4 > >> ide0 at 0xf139c000-0xf139c007,0xf139c160 on irq 19 > >> ide1: Found Apple KeyLargo ATA-3 controller, bus ID 0, irq 20 > >> Probing IDE interface ide1... > >> hdc: PIONEER DVD-RW DVR-111D, ATAPI CD/DVD-ROM drive > >> hdd: IOMEGA ZIP 250 ATAPI, ATAPI FLOPPY drive > >> hdc: Enabling MultiWord DMA 2 > >> ide1 at 0xf139e000-0xf139e007,0xf139e160 on irq 20 > >> ide2: Found Apple KeyLargo ATA-3 controller, bus ID 1, irq 21 > >> Probing IDE interface ide2... > >> Probing IDE interface ide2... > >> hda: max request size: 128KiB > >> hda: 156301488 sectors (80026 MB) w/8192KiB Cache, CHS=65535/16/63, UDMA(66) > >> hda: cache flushes supported > >> hda: [mac] hda1 hda2 hda3 hda4 hda5 hda6 hda7 hda8 hda9 hda10 hda11 hda12 hda13 > >> hdb: max request size: 128KiB > >> hdb: 4128768 sectors (2113 MB) w/1863KiB Cache, CHS=4096/16/63, UDMA(66) Here the drive claims to be 2GB, not 20GB (or is detected as such). > /dev/hdb > # type name length base ( > size ) system > /dev/hdb1 Apple_partition_map Apple 63 @ 1 ( > 31.5k) Partition map > /dev/hdb2 Apple_Driver43 Macintosh 56 @ 64 ( > 28.0k) Driver 4.3 > /dev/hdb3 Apple_Driver43 Macintosh 56 @ 120 ( > 28.0k) Driver 4.3 > /dev/hdb4 Apple_Driver_ATA Macintosh 56 @ 176 ( > 28.0k) Unknown > /dev/hdb5 Apple_Driver_ATA Macintosh 56 @ 232 ( > 28.0k) Unknown > /dev/hdb6 Apple_FWDriver Macintosh 512 @ 288 > (256.0k) Unknown > /dev/hdb7 Apple_Driver_IOKit Macintosh 512 @ 800 > (256.0k) Unknown > /dev/hdb8 Apple_Patches Patch Partition 512 @ 1312 > (256.0k) Unknown > /dev/hdb9 Apple_Free 262144 @ 1824 > (128.0M) Free space > /dev/hdb10 Apple_HFS Apple_HFS_Untitled_2 39924976 @ > 263968 ( 19.0G) HFS > /dev/hdb11 Apple_Free 16 @ 40188944 > ( 8.0k) Free space > > Block size=512, Number of Blocks=40188960 > DeviceType=0x0, DeviceId=0x0 > Drivers- > 1: @ 64 for 23, type=0x1 > 2: @ 120 for 36, type=0xffff > 3: @ 176 for 21, type=0x701 > 4: @ 232 for 34, type=0xf8ff And here you can see that the partition map tries to use about 20GB... so there is a discrepancy between what the partition map says and what the IDE driver says. I suspect old kernel just ignores the later, while newer kernels enforce the limit which causes your problem. Bart, I'm a bit at lost as to why the device size would be misdetected, do you have an idea ? Might be worth getting a dump of the ID block... Mike, can you send us a dump of the binary file /proc/ide/hdb/identify ?
