I have 2.5 USB HDD Transcend StoreJet 25M (TS320GSJ25M) with SAMSUNG HM321HI Firmware: 2AJ10001 inside.

If the drive is formated as FAT32 - WDTV detects it - everything is fine.

If I format it as NTFS (using Transcend utility or Windows XP) my WDTV does not detect it (No storage present). The USB HDD drive is safely removed from desktop of coarse.

I think, I've found the reason of this. It is nonstandard block size of USB HDD. It is 4096 bytes instead of 512. Many linux programms and distros on desktop (Gparted - for examble) work incorrectly with this block size. Here is a screenshot

(sorry for Russian locale). The problem seems to be on WD side to be solved.
Here is the translation for the first line of "fdisk -l" output
Note: sector size is 4096 (not 512).

Here is a report on the HDD from HDDScan Utility

I have checked NTFS partiotion created in Windows on a computer running Ubuntu 9.10. No problems with it!

I think it is something else what's causing the drive not to be seen.
I use multiple drives 2,5" and 3,5" and all are formatted ntfs, and they work perfectly.

Try a partitionmanager and delete the partition, create a new primary partition formatted ntfs
It might solve nothing, but on the other hand..........what's to lose

I have a Samsung S1 mini 250 GB (has 4k sectors and no emulation mode).
I have the same problem that is described above.
You format the drive with FAT32 it works (but of course with Windows alone you can only format 32 GB and none of the free disk partitioners work with 4k sectors by now and FAT32 only works with file size < 4 GB )
An NTFS formatted drive is not recognised. I guess it is a problem of the WDTV linux being not up to date in this case.

However I found a temporary solution. You format the drive with ext2 and use ExtIFS for Windows then it works in both Windows PC and WDTV.

But still this is quite a serious bug thinking that more and more drives will be 4K sector models. And not to mention that WD was one of the first to introduce them.
So please WD - fix that problem.

Latest version still has this bug.

Team: A simple bugtracker would be nice.
