where is the upstream fix ? if the relevant upstream lists dont have a fix, we're not going to come up with one here. I found the disk does not announce it is 4kb formatted. So, there is no problem with Gentoo except the fact that util-linux-ng is named sys-apps/util-linux while the SRC_URI links to the *-ng sources. But this bug report is not about that. http://inkhornnet.wordpress.com/2010/04/03/westerndigital-wd10tpvt-advanced-format And from communication with Tejun Heo, linux kernel developer I can quote: <quote> On 08/21/2010 01:44 AM, Martin Mokrejs wrote: > > Hi Tejun, > > I read a number of docs on the net and it seems I bought WD Scorpio Blue 1TB > > drive which does not report 4kb physical size.

Some BIOSes puke when they see 4KiB logical sector size so drives lie about logical sector size. :-( > > # fdisk -l -u /dev/sdb > > > > Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes > > 81 heads, 63 sectors/track, 382818 cylinders, total 1953525168 sectors > > Units = sectors of 1 * 512 = 512 bytes > > Sector size (logical/physical): 512 bytes / 512 bytes > > I/O size (minimum/optimal): 512 bytes / 512 bytes > > Disk identifier: 0x96df8562 > > > > Device Boot Start End Blocks Id System > > /dev/sdb1 2048 1953525167 976761560 83 Linux Your partition size is properly aligned. As long as it's properly aligned, everything is fine. Thanks. -- tejun </quote> |
