Edit: This problem has been solved with AtvCloner 0.1.4b ! Am happily using the problem child and it works perfectly!

Of the six or so drives I have tested and used AtvCloner on, one drive is indeed my problem child. My Western Digital 750GB Studio Edition external triple interface drive has never worked quite right when attached to my atv whether using the old manual command line method or using AtvCloner. Now AtvCloner actually uses the same system utilities that the command line uses so it makes sense that the problem exists with either method. This issue has been experienced by others, I also heard about it in a response to
my eSata AppleTV Mod on the HandBrake forums.

The issue is that the last step of formatting the Media partition in hfs+ and the volume name “Media” fails with this error (note, it shows up manually in terminal with that method as well as in the activity window in AtvCloner) :

newfs_hfs: /dev/rdisk2s4: partition size not a multiple of 4K.

which means that step has failed. This results in a diskutil list like this:

/dev/disk2
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *698.6 Gi disk2
1: EFI 34.0 Mi disk2s1
2: Apple_Recovery 400.0 Mi disk2s2
3: Apple_HFS OSBoot 900.0 Mi disk2s3
4: Apple_HFS 697.3 Gi disk2s4

Note that partition index 4 is indeed Apple_HFS but is not correctly named “Media”. The resulting behavior when attached to the Atv is that the drive boots up just fine, works fine and in fact can update its atv software just fine, however a Factory Restore will fail. I have run this drive just fine, but it bugs me that it’s “not quite right” so using a bit of google-fu I found a few items of interest that point to the problem, however nothing as a workaround yet for these problem drives.

Update: A new version of AtvCloner is in testing, it seems to fix this problem as I have successfully restored my problem child and updated it successfully. Its a bit of a kludge but works. More to come …..
