I've just had to delete a number of files from my unit as I was down to only 32GB of free space. Having done this, I noticed that my Hummy is showing the following (approx) stats - used space ~ 250GB, free space ~ 175GB and reserved space ~ 75GB.

Can someone tell me what this reserved space is and what it's used for? 15% of my unit's HDD seems like an awful lot of recording space unavailable to me.

hmmm...I meant RESERVED disk space

I think this is for the recording buffer i.e. the box is always recording whatever you're currently watching and stores up to the last 2 hours so you can pause/rewind.

That's way more space than is required for the recording buffer. Even being generous a HD channel using 10mbps will only use about 9GB for 2hrs recording. 75GB would give you a buffer of around 16hrs. I don't have the freeview+ box but the freesat+ version uses a seperate partition for music and photos (at least on the Foxsat-hdr you can change it's size)

Any more for any more? Someone must know what this is for?

Yes, I too would be interested to know. There is even more reserved space on my 1tb machine.

I would imagine it is for the OS (Linux). Some of the info will be stored on the flash rom but I would think that some is stored on the drive.

Also, TV Portal needs somewhere to buffer BBC iPlayer (if you watch your network activity when a programme is streaming it stops after a few minutes and the programme continues to play of the disk).

No OS on the drive which is why you can simply swap it for another.

The Humax would barely need 10% of the amount of space reserved, even for buffering a live HD stream.

Just checked and 114GB is reserved on the 1tb version. Can't imagine what all that is needed for.

I dont have one of these boxes but would assume that it is the space set aside for recordings that are scheduled but not yet made. So does the box refuse to set a timer for a show if there is insufficient disk space at the time of setting it, or does it set it and warn that there may not be room?

If the recordings are for series recordings how would the box know how much space will be required for the full series ? The series/accurate recording crid codes don't have any information as to number of episodes and in case series recordings for shows like Corrie and Eastenders have an almost infinite number of future recordings.

Just the episodes it knows about i.e. whatever is in the guide.

I doubt this is the answer because a friend of mine, who has the same 500GB product, has completely different timers set to me yet his also shows the same amount of reserved space.

114GB is a huge amount of recording from a 8 day epg.

46hrs or so SD material, in any case the reserved portion is fixed and seems to be a percentage of the installed disc size.

Where does the EPG get cached? In memory, or to disk?

I can't answer this for certain but on the freesat+box it's on the hard disc in a totally seperate partition from the recording one. I would imagine it's the same on the freeview+ box, indeed recent firmware upgrades for the ancient 9200 now stores the epg buffer on the hdd.

Could it have something to do with auto-delete so it has more than enough to play with as it records and deletes when the box becomes full.

Raydon has done some investigation on this. The actual reserved space is about 25GB made up of about 1GB for EPG cache, 14GB for buffers for pausing live TV and 10GB which is probably used as cache by the Portal. The rest of the reported reserved space appears as though it might be a fiction to cover the difference between the disk manufacturers usage of GB to mean ten to the power nine and the operating system using GB to mean two to the power 30.

1GB for the EPG cache? Does 8 day's worth of programme listings and descriptions really need that much?

I'm not questioning what Raydon found, but just find it quite shocking!!

I find that unbeliveable...1MB would seem ample to me
(based purely on how much text a 1MB Word document contains).

1 GB is probably the smallest practical partition on a 500GB drive.

No but there is a partition of size 1GB reserved for EPG data; in Raydon's case 35MB was being used.
