Default YH J70: replace harddisk

Hello everyone,

Having noticed that in the last time, several threads were started containing photos of disassembled YH J70s and people stating that they disassembled their own, I wonder if anyone has ever tried to replace the harddisk with something with a higher capacity.
I have a YH J70 with 20GB and I'd like to replace the harddisk with a harddisk with at least 30GB (60 or 80 preferably). I checked Toshiba's site to see what drives are available. From the photos in this forum I can see, that the J70 doesn't use the LIF connector (flat foil cable) directly but instead uses an adapter to some 50 pin connector similar to those found on 2,5" laptop harddisks (though they usually only have 44 pins and are female). Toshiba seems to not build high-capacity disks with those connectors, only the non CE products have those connectors (e.g. MK6006GAH is not a CE drive and has the pin connector, MK6008GAH is a CE drive and uses LIF-connector).
On the drives, the LIF connector is roughly in the middle, while the J70 seems to have it near the right edge of the device.
In addition, the 20GB and 30GB drives are available in heights of 0.2" (5mm) while some (e.g. the MK6006GAH) are 0.315" (8mm) high.

My questions:
1. Has anyone successfully replaced the harddisk of his J70?
2. Is there enough space to fit in one of the 8mm high harddisks??
3. Is it possible to connect the foil cable to harddisks with LIF connectors?
4. Is there some 32GB limit or similar on the J70's controller or firmware? Can it access 40, 60 or even 80GB without problems?
5. Is there anything vital stored on the harddisk that does not appear in the filesystem and needs to be transferred to the new harddisk or is it sufficient to create the directory structure and that's it?

Thanks for your help!
