wrong disk geometry short 100 gig on 500 gig Seagate disk , parted, gparted, qtparted and smartctl report same size

Description of problem: new ide Seagate disk 500gig barracuda 7200.10 wrong disk geometry short 100 gig on 500 gig Seagate disk , parted, gparted (0.3.3), qtparted and smartctl report same size systemrescue disk 0.3.6 with gparted 0.3.4 reports correct size Version-Release number of selected component (if applicable): gparted (0.3.3), qtparted 0.4.5-14.fc7,x86_64 smartctl 5.37 parted 1.8.6-4.fc7.x86_64 with debug and kernel debug How reproducible: every time programs execute and access the disk Steps to Reproduce: 1.launch and read reported geometry 2. 3. Actual results: 400 gig size, short cylinders , gparted 377.76 gib and random crashes on menu access 400 gig disks reported correctly, qtparted reported error on partioning/formating smartctl reports 405,618,581,504 bytes for ST3500830A Expected results: 500 gig size , correct cylinders 976769065 Additional info:
Created attachment 157175 [details] smartctl all report with parted p info appended
uptodate fc7 2.6.21.1.3228 x86_64 debug kernel
Could you please also post the output of "cat /sys/block/sdc/size"? Thanks.
while I was gathering info yesterday : 1: ran cat /sys/block/sdd/size as root and it reported the correct number of cylinders( expected : it was okay since formated in systemrescue , as above)( mounted as usb drive , not ide. 2: I deleted the partions and ran it again , size was still ok 3: ran dd if=/dev/zero of=/dev/sdd bs=1M stopped it at 21 gig , size still ok 4: clicked safely remove ( nothing was mounted ) and disconnected usb and power cables. 5: hot plugged virgin 500 gig sata drive on same usb bridge interface and my system locked up usb (keyboard and mouse too ) cpu monitor frowned at me for 5 minutes and I gave up ( not patient enough to wait and see if it would come back - remembered sata hotplug= no ) 6: booted today sata drive correctly seen , even uninitialised ( couldn't find the ide drive when it wasn't initialised on usb) cat /sys/block/sde/size size correct see screen copies of console ) 7: ERRORs reproducible 500 gig ide on /dev/sdc now seen incorrectly again reporting just over 400gig in all software : smartctl , gparted , qtparted , "cat /sys/block/sdc/size , and I presume parted . Allowed gparted to initialise the partion table, attached are screen displays and log files are available note that running the tools from the root console reports errors in gtk stuff for gparted ( touching edit menu, same errors in evolution startup) and qtparted reports attribute errors (in the console)and mkfs_ext3 errors in the application ( screen shots available)
Created attachment 157514 [details] reproduction of original errors will attach app logs from gparted/qtparted if desired
This has nothing to do with smartmontools. There might be something wrong in kernel since it reports wrong size in /sys.
please post the boot log (contents of /var/log/dmesg) after booting with disk attached.
Created attachment 157977 [details] boot dmseg log just ask ,I'll try to do it.
You have an HPA: ata2.01: ata_hpa_resize 1: sectors = 792223792, hpa_sectors = 976773168 ata2.01: Host Protected Area detected: current size: 792223792 sectors native size: 976773168 sectors http://en.wikipedia.org/wiki/Host_Protected_Area If you are sure there is nothing in there you need, either wipe it or boot with the kernel parameter 'libata.ignore_hpa=1'. This will ignore the HPA on _all_ drives -- so may change their size too. http://fedoraproject.org/wiki/Bugs/F7Common#head-65f561a07fdf2889f310f3aac0ab0f984faf3e9c
the usage of the disk is not symmetrical when I mount it as a usb drive , with no other modification, the full disk is available , even in these tools. I wouldn't expect changing a connection point to change the way the system sees the disk- the tools should work the same on the same disk, no matter the intermediate layers. If it does, I would expect a configurable option/warning message. Till you guided me to the hpa information, I wasn't aware of it's existence, and I've formatted and partitioned many disks.
