Weird backup problem

[Guest markd66]

Having just had my 3rd replacement SPV in 7 weeks, I've kinda got used to backing up to SD via USBTerm and restoring.

But today was the first time I booted a replacement SPV off the (32Mb) SD card and the restore took about 30 seconds! Thinking that something must be wrong I restarted the phone and, yes, there was the dreaded camper van :cry:

A restore via USBTerm didn't help - giving results like:

Cmd 1>> qfs 9

Restore success :shock:

---------------------------

Still, after an hour or so's installing and copying I got everything back the way I prefer it. So I thought I'd do another backup (to the same SD card). Went through the usual qfs 10/0/2/4/8 process, got the usual responses, looked like everything was ok. So I booted off the card and, yet again, the restore took about 30 seconds (of which 29.9s was spent restoring GSM - pboot, wince and ipsm just flashed past).

Ok, so it looks like I've got a duff SD card. Fired up WinHex and took a look - I can see data on the card. So, reformatted the card in my SD reader and wrote a bunch of stuff to the card and read it back without problems.

So now I'm confused. I don't have another SD card I can play with at the moment so I can't prove or disprove the duff card theory.

Has anyone else experienced a problem like this?

Cheers, Mark.

ebuyer delivered another SD card today. Tried the same backup routine using the new card - same result.

After a bit of experimentation, I discovered that backing up GSM is the thing that screws it all up. Don't backup GSM and the restore of the other three works perfectly.

Furthermore, if I back up GSM after the other three then things work fine as well.

I backed up and restored several times and this behaviour appears to be consistent.... anyone?

Strange. Oh well, at least I've got a spare SD card now....
