Do NOT create disk partitions of 2GB and then format them.

Take ages and ages and ages... well you get the picture.

Still waiting,

unless you really think you need them.

(who has quite a number of 2Gig partitions)

They take a lot of memory though.

I tried to attach a 2GB partition to WIN1_ and a 1776MB partition to WIN2_ and got an out of memory error.

I currently only have one 4GB DoM, waiting on a batch of CF IDE adaptors, so I was going to re initialise and repartition the DoM into 8 512MG partitions. That may give me a bit more flexibility and lower the RAM usage.

How much memory does a 2GB partition need?

From the QubIDE manual -

Here is a little summary of different FAT size requirements regarding block sizes used :
 8 KBytes per 1 MBytes of storage with 1 Sec/Blk
 4 KBytes per 1 MBytes of storage with 2 Sec/Blk
 2 KBytes per 1 MBytes of storage with 4 Sec/Blk
 1 KBytes per 1 MBytes of storage with 8 Sec/Blk
 1 KBytes per 2 MBytes of storage with 16 Sec/Blk
 1 KBytes per 4 MBytes of storage with 32 Sec/Blk
 1 KBytes per 8 MBytes of storage with 64 Sec/Blk
A partition of 2 GBytes size with 64 Sectors/Block may be made with a 256 Kbytes FAT size only, but
the smallest file with 1 Byte per example will take a whole block of 64 sectors (32768 Bytes) of
storage

I used a 64 sector block size to get the smallest FAT.

So, I really am going to reinitialise my DoM. There would be far too much wasted space in a 32KB block size.


Whopper

I didn't see you were doing this on a QL - That's really a waste of memory there.

128 to 256 MB sound a bit more reasonable.

Tobias

How much memory does your QL have?

I have the standard 128KB plus the 512 from the QubIDE, so 640KB. believe me it doesn't last long.

Whopper

Huh.... 640K isn't enough? Should be enough for anybody.

We'll have to do something bigger....

Yeah, 640KB is too small.

I'll download some from the internet,
