Mandriva 2010.0 (kernel 220.127.116.11) with a new WD10EARS as disk /dev/sdb. It was partitioned with fdisk, set “u” to get it to show in blocks, and set up the partitions this way:
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Disk identifier: 0xcd895c82
Device Boot Start End Blocks Id System
/dev/sdb1 * 64 1044223 522080 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sdb2 1044288 1953525167 976240440 5 Extended
/dev/sdb5 1044351 9432958 4194304 82 Linux swap / Solaris
/dev/sdb6 9433022 109433021 50000000 83 Linux
/dev/sdb7 109433085 1953525167 922046041+ 83 Linux
wrote the partition table with “w” and it created /dev/sdb1 and so forth. Put file systems in them with:
mkfs -t ext4 /dev/sdb1
and so forth. Could read/write files. Everything looked good.
But it didn’t stay good.
Reboot and - /dev/sdb1 etc. are all gone, only /dev/sdb is there. No such problem for /dev/sda1 etc. (old Seagate 40GB disk.) Went into fdisk, “u”, “w”, and bingo, the special devices were created.
So it looks like udev has some issue with this disk. There is nothing in dmesg to show what went wrong, the lines for sda are equivalent to those for sdb. Here is sda, for which the special devices are created:
ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata1.00: ATA-6: ST340014AS, 8.12, max UDMA/133

sda: sda1 sda2 < sda5 sda6 >
sd 0:0:0:0: [sda] Attached SCSI disk
and here is sdb, where they are not:
ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 310)
ata2.00: ATA-8: WDC WD10EARS-00Y5B1, 80.00A80, max UDMA/133

sdb: sdb1 sdb2 < sdb5 sdb6 sdb7 >

Nothing jumps out at me to indicate a problem.
Anybody know how to fix this??? I want to make the WD10EARS the system (and only) disk, but this is a bit of a showstopper.
