Surely it is not a real Hard disk, but solid state memory - 32GB, with 2GB RAM, presumably directly on the Motherboard, since there is no mention of upgradeability for this tablet convertible. Its partitions may not be modified by usual means, perhaps?
Good point, you might be correct. My Nextbook Windows tablet with 32gb eMMC, though, is 100% just like an SSD or HDD, I can delete everything down to unallocated space.
What Fafhrd says rings a bell. My son's Asus Transformer T100 has 32 GB eMMC but also a separate fixed eMMC of 8GB to store a factory restore image on it exclusively. That 8GB can't be recovered for alternate use - however, the 32 GB is completely malleable as on NavyLCDR's Nextbook.
Looks like you install to the 21.9 GB unformatted space.
Here's a lengthy thread over at Acer Community that may give you some insight on the issue, has to do with WIMBOOT setup on this machine: http://community.acer.com/t5/Legacy-...on/td-p/316526
One of the articles that thread links out to: https://blogs.windows.com/itpro/2014...-boot-wimboot/
If all else fails download any LINUX live CD disto -- probably Linux Mint is the easiest for beginners and then delete the partition using Linux PARTED command -- just GOOGLE for Linux PARTED command.
It's probably better to investigate what type of partition this acer recovery partition (partition number n=4, maybe 3, I guess) is - Diskpart list part should tell unambiguously:
Probably a type 27, hidden, diag type
They usually can be unhidden simply by assigning a drive letter (below, X= drive letter of choice, something not in use)
sel disk 0
sel part n
or to change type to normal ntfs type 07
sel disk 0
sel part n
set ID=7 override
But if other diskpart commands are not working, perhaps these will not either.
It's a GPT disk with non empty partitions, presumably, hard to crack, it seems.
If you can get hold of the factory recovery disk contents, there will be cmd scripts, or even batch files which show exactly how the partitioning is performed, if other Acer recovery partitions I've seen are anything to go by, often hidden in multipart Wim (SWM) files.
(It should also be possible to assign letters to all partitions, except the unformatted space)
as found for an ASUS Transformer T100TA like my son's and mentioned in the Acer thread I linked to.Code:rem === 4. Images partition ========================create partition primary format quick fs=ntfs label="Images" assign letter=m set id="de94bba4-06d1-4d40-a16a-bfd50179d6ac" gpt attributes=0x8000000000000001

Also, in that same Acer thread, a couple of posters reported that once they were able to force delete that partition, the system was unbootable and had to be restored. If completely reformatted to go generic and not have WIMBOOT intact, they ended up actually losing ground on space remaining for use on these 32 or 64 GB drives.
