Used Disk Space under EOS 4.61

Hi,

i'm new here and have a question about how my E 4XT Ultra is counting used Disc Space. I bought my XT Ultra on ebay, it has a 20 GB Harddisc. When i got the sampler the harddisc was empty. The HD has a discspace of 19616 MB. A while ago i copied a Sample CD to the HD, Folder has a "Total size of all files" 427,1 MB.
Some days ago i made a new folder to save other Banks, Presets and Samples there.

What i'm wondering about is this:
Folder 1 has a "Total size of all files" 427,1 MB
Folder 2 has a "Total size of all files" 16,2 MB
But when i get info about the whole Harddisk it says "Used 576 MB". When i add the two foldersizes i only get 443,3 MB. What are these 133 MB more discspace?

these are the actual sizes after making my last savings. Before this the situation was as i can remember:
Folder 1 has a "Total size of all files" 427,1 MB
Folder 2 has a "Total size of all files" 15,7 MB
But when i get info about the whole Harddisk it says "Used 560 MB".

So Folder 2 is about 0,5 MB bigger, but Disc Info says 16 MB more used (560 to 576).

What is this? can anybody explain it please? Maybe A Harddiskerror? Or is it typical for the EOS to work like this?
My HD has the Filesystem E-Mu 1 (info about the HD). Is there another Filesystem available, something like E-MU 3?

Hello!

The own Emu Format divided every harddisk into 1024 clusters!

For example:

1 GB harddisk - each cluster is around 1 MB
10 GB harddisk - each cluster is around 8 MB
20 GB harddisk - each cluster is 16 MB

So, if you save a 4 MB bank, it needs 16 MB on the harddisk.
So optimize your banks to 16, 32, 48 MB ......and so on.....

Or far more better, install EOS 4.7 and format the harddisk in FAT.

Hope this was helpfull!

thanks a lot for your answer, this clears my question.
so on the other hand there is always the limitation that you only can save maximum 1024 Banks - if formatted in E-MU 1 Filesystem, right?

Is it recommended to format in fat32 the internal "boot" hard disk?

I have read on this forum that fat32 is recommended for backup disks, i.e. for exchange with PCs,

but that EOS-formatting is recommended for quicker and more efficient loading and management of data by the sampler.

Is that correct?

Does fat32 on the main disk entail just a minor decrement of performance (e.g. slower loading),

Or is it risky for data (corruption, glitches, crashes while playing/editing, etc)?

Or is all oif that just a urban legend, and one could easily format everything to fat32 and still work smoothly?

thx

@virtulant: Yes, maximum possible banks are 1024.

@ozy: The internal harddisk isn´t a "boot" disk! The Operating System is in the Flash CPU Ram. It is your turn to do what you want with the internal harddisk.
I have two Ultras. One with a 20GB IDE HD in Emu Format, and the other with a 40GB IDE HD and Fat Format.

Never had any problems with both of them.

I think for Live Situations, a little Emu formatted HD has the advantage of faster loading, but in the studio I have time to wait a few seconds longer for "Fat" instead of "Emu".

just my 2cents

What! this is the max number of banks irrelivent to HD size/format type? :cry:

Hi!

I think so. But this is only for the "EMU" Format!

Andrew Longhurst (one of the best at Emu) had written an email to me (very long time ago......1996), where he had described, that each harddisk which is formatted in the "emu" format, is divided into 1024 clusters.

In the early years of sampling, E-mu had the advantage of faster loading and saving with this system.
But later, this format wasn´t up to modern standards....

so you have a maximum of 1024 banks on an "emu-formatted" HD.
