it has jumper positions and I tried it. But it does not help. But the description of WD is a bit vague about the jumpers on newer drives.

OTOH if it would be a 4k drive only I think I couldn't partition and use it on OS/2 anyway, right?

Is there any possibility to force MiniLVM to create partitions on 4k boundaries? Maybe DFSee?

Some say that it is possible using a dummy partition and the right math. Remy had a similar issue and opened an issue about it. The conclusion from Arca Noae was that it was not possible.
Simplest would be to get a USB drive, perhaps 1TB. Format it under OS/2 as JFS and copy under OS/2 everything to it and then copy it from Linux. This would be the safest but some USB enclosures actually force 4KB sectors. I have a 1TB and a 2TB USB drive that work fine under OS/2 and Linux and this would work with them.
Looking on the Internet, I found https://superuser.com/questions/679725/how-to-correct-512-byte-sector-mbr-on-a-4096-byte-sector-disk which suggests using a loopback device to force 512 sectors, might be save enough if you only use it as read only.

Andi B.:
I never could get USB working fast on OS/2. Maybe on my new system USB3 would work but not on my old one. Would transfer over LAN instead. But our samba is not that stable too IMHO. And FTP is terrible slow with a lot of small files. Seems I've to rar it and then FTP over LAN.

Dave Yeo:
Still weird that Puppy Linux could mount the volume. If the problem is sector size, I'd expect all Linux dists to fail.
