A Sandisk Thumbnailscrew

OK, one may presume, for embed or dedicated applications.

Applications you can reach around and stick your hand into for, say, a
fanny-packed handheld device;- I haven't one, actually, to speak of,
but rather a simplistically engineered, psycho acoustically-chipped,
shirt-pocket radio. Midnight Cowboy at the drugstore corner stuff for
the twenty-first century digital revolution: You need to know what
the hell you're doing to play.

Behold woe, though, should you even remotely expect Sandisk's SD TF
Flash Memory, MicroSDHC class cards, its controller, specifically, to
be so forgiving if placed even remotely near a PC environment proper.

They'll break like hell;- Hell, literally, means what Sandisk is about
when you'll seek resolution from their warranty qualifications. Yes,
that means they even want photo JPG images to qualify considering
10-year or lifetime warranty card stipends.

To visit the Sandisk hell is easily accomplished. I suggest buying
anything above 16GB in their Class4(-10) SDHC offerings.

Question: How, too, can I get to see Sandisk's hell.

1) First you want to spend your money in order to do so.

2) Then you'll need a USB adaptor to format it, on your Personal
Computer, thereby rendering it qualifiedly* useless and irrevocably*
broken. Please to note: Sandisk as well provides their own format
utility, which equally will run, upon their products, to render them
no better than as useless as from a PC-formatted environ.

* It is strongly upheld, that you visit Sandisk's friendly automated
Warrantee Consideration Department for further, in-depth perspectives.

Best take it straight from the horse's mouth: An aftermarket industry
for compact memory is rife with relatively easily hacked controllers
on compact cards reporting larger memory capacities, than, in
actuality, a smaller quantity of physical memory rewriting over
itself, over potentially established data prematurely, in order to
achieve that degree of exploitation.

Just buy another copy.

First I bought a 16G MicroSDHC - a Sandisk.

Then I bought a 32G offbrand: Welcome to after-market, hacked and fake
controllers. (Cards which begin to rewrite themselves, over
established data, prior to the card's stated capacity.)

So I went back to Sandisk. AKA, still a 32G "4K card" or FAT32.
(Larger, 64G cards, use FAT extended, FATExt.)

I also downloaded Sandisk's website utility for formatting their
cards.

I killed every one of the above cards. They're useless now. I'll
send you them for filler for the bottom of your favorite trash can.

The 16G card still works perfectly. I did not manage to kill that one
by reformatting, initiating the disk it with either Easus, AOMEI, or
Windows' native Disk Manage. The 16G was also my initial impression,
a favorable and normal one, for this class of memory storage. Now
qualifiedly with a touch of fear.

These cards are for handheld devices, e.g. Google's latest
Candy-Coated Android for a handheld, camera medium, in other words
something not quite ready for Prime Time, such as an actual Personal
Computer.

My latest Singapore wonder, a $10 MP3 chipped radio uses MicroSDHC.
The engineer only speaks Chinglish and hangs on Amazon. Bad choice,
implementing MicroSDHC, when he's recommending specific brand names
he's only tested (across a field rife with fakery & hacking, with even
known brand names operationally inconclusive). I also wrote a few
comments, fairly neutral for based on the logistics of laying in
MicroSDHC file formats, according to the logic of how the perceives to
order a play list. Perhaps he mentioned what I wrote, in his own
particular explinations, after deleting my post for an unrelated
technicality.

In any event, I've ordered another one of his products (in another
variation, this time, though, encompassing both USB and MicroSDHC). I
can presume that when the item arrives I will be able to correct for
the engineer's shortcomings for implementing MicroSDHC in a situation
where a real computer is needed to handle a better class of storage
solution.

That's the plan. Delivery is slated for later today.

Got it.

Nice and shiny, shiny unit in a Candy Apple Red.

Picked up my USB 64G flashstick fine. Sequenced buffering of file
copies evidently conflicts with NAND controllers, as well and
similarly as it does to MicroSDHC thumb cards. This in turn causes
the MP3 unit to misidentify direct keypad input to music tracks.*

Now, if I can format a USB flashdrive, then I needn't follow your
suggestion and throw away mo' money into the micro-card flash
industry, or any other industry, we may hope, not up to prime time.

Besides, with that 16G MicroSDHC I'd laid about 2000 song tracks;-
with the 64G USB thumbdrive I should have 8000 song tracks available
from a unit, no bigger than deck of cards, that fits in my shirt
pocket.

*Basically, it plays by the sector/cluster format, sequentially, e.g.
song1 being located on HDD device sector1, and song9999 on HDD
sector9999. That means patience every time 8000 songs are copied to a
computer HDD, modified with additions and so forth, whereupon to copy
back in a final format to the thumbdrive's controller (at odds from
that manipulation): A special HDD optimizer progam is required, which
I have (it's commericial), that is then capable of ordering file
[re]placement according to the logical ordering of a thumbdrive's
format, by ascending numbered clusters corresponding to ascending
numbered file names.

Got it?

That may likely be interpreted for a thumbdrive controller's
hardwired "wear leveling" implementation;- The file copy buffer I'm
sending it certainly is not out of sequence.
