U727 - SDHC Memory

Any reason an 8GB microSDHC wouldn't work in the U727's reader?

I'm thinking about getting the Sandisk.

Too bad 3GStore doesn't have it. =(

I don't know anyone who has used an 8GB microSD card in their 727. Largest I have used is a 4GB...let us know if it works!

Sprints specs on the 727 say "This device has a microSD slot that supports up to a 4G memory card" so not sure if it will take an 8 or not. States the same thing on Novatel's site, 4 gig max.

Yeah, I was hoping they state 4GB because either 1) Sprint doesn't carry 8GB microSD cards or because 2) 8GB cards didn't exist when the spec was written.

The reason I posted that was not long ago several PDA's were NOT taking over the identified size of SD and MicroSD they advertised. They weren't compatible for whatever reason. I'd try one if I had something else it would work in if it doesn't work in the modem is all. The U727 is a relatively new device as well. Not like it was made a couple years ago. Would be interesting to see, but I'll let soembody else try it lol! Smile

I think it depends on the "Speed performance rating", example, "Class 4" that the SDHC is rated. There were other threads up here where people had problems with different SDHCs, so make sure there is a return policy before ordering.

I will try to find out what the specs are from Novatel directly.

Cool, thanks Michael!..... Quick question as I scratch my head here... can the Sprint software be loaded to the SD card versus your hard drive? I've had some very weird happenings since I loaded the Sprint software. No problems running in the NDIS mode at all though.

In the non NDIS mode I get an error where the software must shut down and sometimes get a quick flash of the blue screen of death (XP Home) and the system reboots. After reboot it says system recovered from a serious error. Of course I look at the error and it look like ancient Greek lol. thought I'd try loading it to the SD card maybe. If I un install though the 727 will keep it's NDIS cionfiguration right? As long as I disconnect it before uninstalling the connection manager. This may all be a mute point too as I suspect once I get my CTR350 Friday it may not be an issue!

Michael - Did you get any info from Novatel yet? I'm anxious to fill that tiny little slot and I'm debating whether to bother trying an 8GB card or not.

Are all 4GB microSD cards now microSDHC? Or, are the non microSDHC ones the old school "TransFlash" labeled ones?

Thanks!

I can confirm that this model does work, but with a catch-22. http://www.amazon.com/SanDisk-MicroSDHC-Memory-MobileMate-Package/dp/B000WPDKRI/ref=pd_bbs_sr_5?ie=UTF8&s=electronics&qid=1206533953&sr=8-5

DO NOT, AND I REPEAT, DO NOT TRY TO USE THE MINI READER THAT'S IN THE PICTURE/PACKAGE! The reader I'm talking about is in the pic that's on amazon. I tried looking for the original pic at compusa (where I bought it at) or sandisk's site, but it isn't on there. I inserted the micro card into that specific reader and the fit was so tight that it wouldn't release it. I tried as hard as I could to pull it out with my fingernail, but it wouldn't budge. I could have used something harder, but I didn't want to dent, smash, or scratch the micro card. I ended up cutting up and destroying the reader in order to get the card out. I suggest a different type of reader like this setup(fortunately, I had this from when I bought a 4gb card previously) (I can't seem to find a 8gb micro sdhc with the sd card and usb adapter, like the pic. They might need to be purchased separately if available). http://www.amazon.com/PowerLab-SDSDQ-4096-A11M-Sandisk-Micro-Sdhc/dp/B000UZVKO0/ref=pd_bbs_sr_7?ie=UTF8&s=electronics&qid=1206534776&sr=8-7

That reader works fine in my macbook and I tried the old 4gb micro card inside the sd card adapter in a high def, flash based camcorder and it worked great. The old 4gb is a class 2 and the new 8gb is a class 4. I didn't try the bigger card in the camcorder yet. As for performance, both the 4gb and the 8gb are dog ass slow (writing was the only test I did with the 8gb). I tried copying a 870mb movie file to the card inside the u727 and the speed was about 2mb per 3 seconds. I did the same thing with the 4gb card and got the same results in speed. I found this somewhat unacceptable for normal use but I guess it will just have to do for backup usage for now. It almost acts like usb 1.1 speeds in my opinion in the u727. Trying it out in the sd card adapter, inserted into the white usb adapter (pictured in the above second link), it was nice and fast! I don't remember the boost in speed time measurement but it was a night and day difference.

So, in closing, the Sandisk 8gb class 4 micro sdhc does work in the u727, but don't use the little black and red reader that might come with it. My suggestion for a reader is the sd card + usb adapter setup. It might be kinda bulky but it works great and can be used in things that can use sdhc sd cards too!

I just bought the same thing at Best Buy. Here's what I've found...

When inserting the brand new card into the U727, Windows Vista prompted me to format it, and Format said the maximum size was just under 4GB formatted. So, I guess it doesn't read 8GB cards.

Then I used the bundled reader, and used that to format the card to almost 8GB, then put it back in the U727.

At this point, Windows reads the card fine, and thinks there's almost 8GB free, but when trying to copy 7 GB of content over, everything past about 3.5 GB fails...

The bottom line is that the 8GB card works, but only as a 4GB.
