I just bought two of the WD Green 500GB drives to be used in a hardware RAID (Adaptec 2610SA, aka Dell CERC SATA1.5/6ch) on my Ubuntu-based server. I was going to format it in ext3. Will this problem affect me?

You should be immune. It seems that only >640GB drives have this problem. See the affected drives.

WD Align software aligns partitions on the Advanced Format drive to ensure it provides full performance for certain configurations.

Yes, certain configurations: XP. According to WD, Linux is not affected by this (but that's been proven to be false).

I'm happy to see that you saw the stalling disappear as well, it gives me confidence about the cause.

Time will tell if the the lock-ups were caused by the 512b partitioning (I wasn't able to repartition my drives until a few days ago), but it's a bit reassuring to know that I wasn't the only one experiencing these annoying as fsck freezes.

The affected drives on my end are WDC WD10EACS-00ZJB0 and WDC WD10EADS-00L5B

I noticed both a performance hit AND stalling for a minute at a time when there was a lot of HDD activity, so I can confirm part of your experience. After going with 56 sectors per track as well, the freezing seems to be a thing of the past. The speed is definitely greatly improved.

The problem is that WD doesn't tell the system about the sector size.
dev/sdd:

Model=WDC WD15EARS-00Z5B1, FwRev=80.00A80, SerialNo=
Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=50
BuffType=unknown, BuffSize=unknown, MaxMultSect=16, MultSect=16

It looks to me that this should *really* be fixed by WD with a firmware update

.

Solution: Instead of fdisk, call it as fdisk -H 224 -S 56 as per Theodore Tso's blog.

This is OT, but:

man depmod

depmod - program to generate modules.dep and map files

If you mean you want the modules in the .deb file, use the --initrd parameter as well as a script, such as
/usr/share/doc/kernel-package/examples/etc/kernel/postrm.d/initramfs
/usr/share/doc/kernel-package/examples/etc/kernel/postinst.d/initramfs

...as is mentioned in /usr/share/doc/kernel-package/README.gz
