Help Phone crashes when copying a lot of data from PC to SD card

Anyone knows of a bug that causes the phone to reboot when copying a lot of data from PC to the SD card?

My Spectrum rebooted while synchronizing music from Windows Media Player (Win7x64) after copying about 2GB of about 12GB. For my wife's phone I used Windows to copy from backup and that also crashed after a couple of GB went over. I eventually pulled the card, reformatted (FAT32 table was corrupted from the crash) and then copied all the data using a card reader.

Synch'ing smaller amounts of data seems to work fine so I'm curious if there's a problem with the I/O drivers on the phone or if the SD card that VZ puts in there (Kingman brand) has a problem with large data transfers.
 
I've never had a problem, but then to be honest, I've never tried to move that much at once.

Try using the SwiFTP server download from the Market installed on the phone and FileZilla or another FTP client on the PC. Maybe it's speed related.

I'd be weary, very very weary of using the card if it wasn't formatted in the phone, with the phone's Format option. If I formatted with a PC, I'd use nothing but SDFormatter.

YMMV.
 
when i got my phone i copied about 3 gb over form my Ally sd card through windows
with no issues. It doesnt seem like I have seen anybody with this issue. Itf i have time tonight ill play and see if i can similar results. I have been wanting to add some music to my card, ill add 2 or 3gb and see what happens.
 
again I don't use the stock sd card but I've moved over 16GB off the phone onto my pc and back onto the phones sd without a hitch.
 
Are you talking about a drag and drop of data or some kind of Windows sync?

If you're using a sync and the data amount is large enough, the phone might go into standby with the screen off, especially if the sync is through wifi and you have don't have persistent wifi enabled in settings; it kills the connection after the screen turns off.
 
I have not had issues with data over 2GB transferring via USB to a 32GB class 10, but oddly enough had a reboot during a copy of the V6 Nandroid while on BO3 while simultaneously recopying BO3 and Eclipse v0.2 Roms to another location on the SD.

USB connection to Win7x64. One phone crashed when synching through Windows Media Player, the other with drag-drop. I believe the card that came with the phone is Class 6, Kingman.

I've frequently copyied 15GB back and forth on my old LG Ally so figure there's something funky about the SD driver/interface of the Spectrum for it to happen to two phones. Workaround is to use a card reader when moving lots of data but with the Spectrum's design, pulling the card out on a regular basis is not an easy task.
 
Hmmm. I can see why a sync would do that, but drag and drop shouldn't. I've had reboots when I tried to upload 5gb through a wifi app, but the phone overheated.

Well. I'd still try drag n' drop FTP. I would not be cycling the connector on the microSD port. No way, no how. Don't care how critical the data is. That's a sure fire way to make the phone become unstable doing reads/writes. They just were not designed for many insertion / removal cycles.
 
I forgot to add, when I have a lot of stuff, I just pop the SD card into my laptop and do the transfer there. I did that after the phone timed out on me during a transfer.
 
Last nite, I transfered about 9.x GB to a 32GBsd card from my laptop with no issues whatsoever. I'd try a different SD card for sure
 
Thanks for sharing your test results. I'm planning to get a Class 10 32 GB at some point so that will be a good test when transferring the data over.
