It sounds like this idea is possible, however whats the point exactly. From my understanding (no one brought it up) the nano has a limited database for up to 1000 songs (for the 4gb). So the nano will only show the 1st 1000 songs...are they also updating the software to support the more songs in the database? Also, what exactly is the actually user compacity of a 4gb nano...someone mentioned about 3.7gb of actual user space...I can't seem to find that 1 out. Anyways, just some more food for thought]]>Mar 26th 2006 10:45AMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/Mar 29th 2006 5:41PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/Apr 4th 2006 12:58PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/

Obviously the ones discrediting these claims are the ones that lack the intelligence or creativity to understand such a concept.

4gb nanos used a couple different revision mainbaord setups including the original 2gb type with two CS (chip select) lines and two tssop locations, the other used a daughterboard and the connector could be removed and the chips located just like the latter version.

The samsung chips are a "stacked package" from the factory. No one is piggybacking chips.....

It involves 'stacking' the RAM chips on top of each other. I guess the logic inside the chips deals with addressing and access over the same bus. Pretty slick.

If you look at his hack he clearly has two of the 4GB chips. Also he mentions it only cost $80 for the extra chip...Not to bad considering how much a 4GB compact flash drive goes for....



I imagine we will hear soon from Apple the 8GB nano and the 16GB nano, remember they get these chips for about half as much as any of us can, $250 and $300 respectivly will be Apple's price point.]]>Jan 12th 2006 1:54PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/Jan 12th 2006 2:02PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/

When you buy a Nano (or any flash-memory device, really), you ACTUALLY get the amount of storage advertised.

and..



The hard-disk based players rip you off with this whole decimal interpretation of what "Giga" means.





In actuality, the reason that there is less than advertised space is because you need to format the storage. This is also true of the flash-based storage devices. My 40GB "Apple iPod Device" actually has a 40GB hard drive in it, but a portion of that is set aside for formatting the drive, leaving something like 37GB available or something like that. The same would happen with a flash player, or any type of flash storage (for instance, my 512MB memory stick actually only has 491MB of available space after formatting).]]>Jan 12th 2006 3:41PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/Jan 12th 2006 3:48PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


- All three 4GB Nanos that I have opened to date use a daughter board that has two 2GB flash chips, one on each side of the board.



- The part number he LINKS to is the same part number that is in all of my 4GB Nanos. It is a 2GB part.



- The part number seen in his pictures is a 4GB part number, which can be seen here: http://www.samsung.com/Products/Semiconductor/common/partnumbersearch.aspx?partnum=K9NBG08U5M&cd1=&x=0&y=0



- If what he claims is true, then that board that he has pictured has FOUR 4GB chips, meaning 16GB of available flash! Don't you think he would have bragged about this if it were possible?

Now if only it were actually that easy. There are very specific processes you have to go through in order to make it work, and I'm sure there are some later generation iPod mini's that will not let you do this due to restrictions they've put into place.]]>Jan 12th 2006 5:09PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


a 40GB drive is 40,000,000,000B - that's how manufacturers measure, as in 1,000B = 1KB

For example, my 120GB WD drive has 120,031,477,760 bytes of capacity. But a Kilobyte is actually 1024 bytes (2^10) and a megabyte is 1024 kilobytes. So that 120,031,477,760 is actually 111.8 GB. But who wants to advertise a 111.8 GB drive. To avoid confusion, drive makers should just give enough capacity so that when you format, the drive actually has the capacity rated on the box.

This just in... byte =/= bit.]]>Jan 12th 2006 9:25PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


Oh, and as for the people saying you should just buy a full-sized iPod, this isn't exactly something the mainstream is going to do, it's more or less something that's just being done because it's "cool" (oh, and the nano is a lot smaller than the full-size iPod, which could be part of the appeal).]]>Jan 12th 2006 9:38PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


16gigabits = 2gigabytes (since 1 byte = 8 bits).



keep this in mind if you plan on buying any flash chips because they commonly refer to their chips in terms of "gigabits" which is aggrivating to people who are used to "gigabytes".]]>Jan 12th 2006 11:54PMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


Figure out your basic binary concepts before you attack.



#23 Used GB not Gb, that's GigaBytes, and he never went to bits, he was only dealing with the differences between the decimal and binary definitions of a GigaByte, so the conflict has absolutely nothing to do with 1 byte = 8 bits.



40GB = 40 x 10^9 bytes = 40000000000 bytes = 320000000000 bits

40GB = 40 x 2^30 bytes = 42949672960 bytes = 343597383680 bits



Why is the latter the way programs see it?



First, you need to realize that a byte is not a quantity at all, it is a distinct combination of 8 numbers. Now you can have a quantity of bytes (i.e. 4 bytes) but these are not sequential digits; 4 bytes means 4 DIFFERENT bytes.



In one particular byte, there are 8 binary digits as you see below:

0000 0000, this offers 256 distinctly different bytes.



At this point, a bit is totally irrelevant since a byte is always made of 8 bits, that never changes and a bit in itself is meaningless datawise.



The nearest approximation to 1000 possible distinct types of bytes in powers of two (since binary is a base-2 counting system, meaning it increments in 10's every 2 digits) is 1024 (or 2^10). Sure, we could have wanted it 1000, but bytes are dealt with by programs that count in base-2, and to them:

1000 = 11 1110 1000. Surely not a squarish number to us.



1000 may be easy for us to compute, but since none of us will ever look at the binary, why not leave it a squarish binary number to make it more orderly?

Thus, it happens that 1024 = 100 0000 0000 = 2^10, called 1 KB.



Hence we need to square the amount of distinct bytes to get to 1 MB, or

2^20 and again to get 1 GB, or 2^30 distinct bytes.]]>Jan 13th 2006 1:06AMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/


For instance, Hitachi drives have (or have at least until recently, I don't have a brand new one) consistently more total storage space than at least Western Digital and Seagate drives. My brother's 120 GB Western Digital is 109 GB whereas my Hitachi 180GXP 120 GB (due for a pension soon) is 115 GB formatted. I'm pretty sure both of these have 2 platters. I've also seen this with some larger Seagate and Hitachi drives of mine, but I forget the numbers.



Note: This is not me advertising for Hitachi.]]>Jan 13th 2006 3:26AMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/

For a hard drive as it comes from the manufacturer, it means 10^9. For an OS, it means 2^30.



So a 40GB iPod uses a 40GB hard drive, which only has 40 billion bytes on it. Divide that by 2^30, and you get slightly more than 37.25, which is the binary gigabyte count. Considering that filesystem boundaries are determined by binary chunks (clusters/blocks ranging from 1024 bytes to 65536 bytes,) the functional capacity really should be measured in terms of binary arithmetic anyway.



Essentially, your new hard drive only has about 93% of its advertised capacity. That number does drop a bit due to filesystem overhead, especially when you have to account for journaling and assorted metadata.]]>Jan 13th 2006 10:43AMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/Jan 14th 2006 2:28AMhttp://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/http://www.engadget.com/2006/01/12/hack-your-4gb-ipod-nano-to-8gb/
