Nuvi 650 SDHC card writing bugs
Bruce.
written when connected to a PC. I started with an empty 4GB SDHC card and
tried to transfer 750 songs and a playlist to the root of the card. It
quickly started to fail as the copy passed about 400 files or so. The card
reported "full" and would not take any more files despite being less than
half full. While a FAT32 has no maximum limit on root files, I decided to
try a subdirectory next anyway assuming the Nuvi might have a root file
limit not inherent in FAT32.
Sure enough, starting over and writing files to a subdirectory completed
instead of erroring out.
But then problems quikly developed trying to use the gps mp3 player. It
would only play the first 32 songs over and over in shuffle mode. I
couldn't get it to access the remained of the card.
In the meantime, a new SDHC card reader I ordered arrived, so I decided to
start over again using that card reader instead of a gps, and the card
reader is MUCH faster writing cards than the gps is. I could write 2GB in
15 minutes instead of 90 minutes.
When I tried to just delete the files already on the SDHC card, the windows
explorer went nuts and started displaying numerous copies of the same files.
No matter what I tried, I couldn't get those stuck files to delete.
Something was damaged on the card, which would explain the player problems.
So I then used the Windows reformat to reformat the card.
After that I copied the same 750 files back to the root directory again,
this time with my new reader, and this time completing without reporting
errors. All 750 now play normally in the gps. No problems I can detect.
The moral I take from this is don't use the gps to write SDHC cards. It can
screw up the card contents. A separate card reader works much better. My
guess is the bugs don't happen until you get in to the higher file counts,
near the 1000 limit of the gps.

That's not true of FAT32. It was true under FAT16 but FAT32 eliminated the
maximum root size. It can now take up the entire disk. The SDHC cards are
formatted FAT32.

Yes, while the Windows explorer uses the actual file names, the gps MP3
player displays the ID3 tags from inside the file. That's common for music
players.

In my case, when I use my reader, it's limited by the write speed of the
SDHC card more than anything else. A faster card would write faster. The
gps is another story. It just has a slow write speed to memory cards.

It's 100% idle. No other tasks comsuming resources. I have a 2.4GHz CPU.

Reformatting using Windows and my card reader fixed it. Only writing it in
the GPS memory slot corrupted it.

Me too. NTFS doesn't have the root directory problem either. In the past,
smaller flash memory cards used FAT16 so they would have had the root
directory limit. But these new cards exceed what FAT16 can do so FAT32 is
used instead.

Me too. At that time I will see the filenames. However, when I use the gps
mp3 player, it doesn't display the file names but rather the internal ID3
file tags instead.

My card is class 6 as well which works out to be 6MB/sec maximum. At that
rate 4GB will take 716 seconds, or 12 minutes assuming 100% bandwidth
utilization, which seems unlikely. It can't get faster than that. So the
15 minutes for my card reader is not far off the mark.
What is very different is the write speed of the gps. That's MUCH slower.
It took me close to 90 minutes to fill a card using the gps and the same USB
hub and interface.

Yep, almost 50 GB.
> Interesting! but as long as it works will do.
Yes, I got MUCH better results with my card reader than using the 650 to
write the card. I will never again use the 650 to write an SDHC card, at
least not anything bigger than a few files at a time.

[card writing issues on the nuvi]
Unless you bought your new card reader quite a few years ago, I suspect
it's usb2.0 high-speed capable.
The nuvi 650 is only capable of usb1.1 full-speed operation -- many times
slower than usb2.0 high-speed. So it's hardly surprising that your card
writer is faster than using the nuvi as a writer.

Yes. It's only a week old and is USB 2.0.

Thanks for confirming that. I did a lot of searching but couldn't find any
place where Garmin said 1.1 or 2.0.

Hmmm. This page says the 350 is USB 2.0. Is that right? My 650 is USB 1.1
but the 350 is 2.0?
"The USB-2 (full version 2 speed capability) port on the side can be used
for map/MP3/Audio Book/image/file loading. "

Actually, in the technical specs section of the very web page you note
[well beyond the line you quote], it says:
"...Interfaces: USB (ver 1.1, No RS232 serial port.)..."
The reviewer's early mention of:
"...full version 2 speed capability..."
is not actually a meaningful description in terms of any of the official
usb.org naming conventions. There is usb 'full-speed' [the fastest of
the usb 1.1 speeds, and still supported by the usb2.0 specification], and
usb 'high-speed' [the fastest of the usb 2.0 speeds, and not supported by
usb1.1 interface hardware]. If we assume the reviewer actually meant
'full-speed' when he says 'full (version 2) speed' [since usb full-speed
is indeed an officially supported speed of usb2.0 devices], then we are
still talking about plain old usb1.1 full-speed.
But actually, the reviewer's later identification of the interface as
'ver1.1' is the most accurate statement.
Equipment makers tend to cover up the fact that they are not actually
selling a 'high-speed' capable device by using terms like 'usb2.0 full-
speed' -- which, while correct, is actually no faster than usb1.1 full-
speed -- and, as noted, is many times slower than 'usb2.0 high-speed'.
Many top brand names have used the clearly misleading 'usb2.0 full-
speed' description while they were closing out devices that used the old
top speed standard [old chip inventory], while making it sound like they
were offering the latest interface hardware.

Other than timing transfers, one way to convince yourself is if you have
an XP machine with both a usb1.1 card and a usb2.0 card. In that
situation, if you plug a usb2.0 high-speed device into the usb1.1 card,
XP will give you a warning that you are using the device at a less than
its' optimal speed, and you will be advised to allow XP to show you a
better place to plug it in. If it's a usb1.1 full-speed device, you will
get no such warning when plugging into either card.

Actually, I think it less forgivable that they don't support Windows
98sp. That'just a software issue. The nuvi hardware is already built,
and that they can't change -- but the software they can -- particularly
as the necessary driver is completely external to the device.
[If you are in need, a google search for 98DRIVER_vDE050512.EXE will
bring up a 98sp driver that supports the usb mass storage spec just fine
-- and allows me to mount my 660 on 98sp just fine -- including giving an
'eject hardware' button in the tray. Your mileage may vary...]

That's a good idea. I wish I had a 1.1 port to try that but I'm all 2.0
now.

I think that makes Garmin the very last company in the known universe still
making 1.1 hardare.

Actually, the quite new zoom h4 multi-track handheld recorder also only
supports usb1.1 full-speed transfer -- despite the fact that the h4,
unlike the nuvi, which has little need for data transfer in support of
it's primary operation, lives and dies on transfer of recorded audio
files [including even uncompressed wavs, which tend to be quite large].
To top it off, they made it almost impossible to remove the sd card to
use in an external reader [unless you slap a piece of scotch tape on the
back of the card to get a grip on it].
The world's silicon folks must just have made many too many usb1.1 parts
that are clogging up warehouses somewhere....

That cinches it. 1.1 it is. Thanks.
The 650 series takes up to a 8GB card. I don't even want to think about how
long it would take to fill that at 1.1 speeds.

> Can it be loaded with a (usb 2) card reader?
Yes, that's what I do now that I have a SDHC compatible reader. And as far
as I'm concerned, the Nuvi card writing has bugs in it and shouldn't be used
anyway to write SDHC cards. I had to reformat mine under XP and use a card
reader to write the card correctly.

All I can think of is manufacturing volume. I imagine a lot more devices
use SD cards instead of CompactFlash cards these days. I think the biggest
remaining CF use is in high end digital SLR cameras.
> And I feel lucky I didn't buy the Class-2
Yes, me too. I had trouble finding reasonably priced class 6 cards and I'm
so glad I didn't settle for class 2.

Uh oh. Unless the 660 is USB 2.0, you shouldn't be seeing that.
