Corupted 920T Help Please

Hi,
Was downloading speed cameras last night and PC had a fit which in turn caused the 920T to lock up, I have done the reset etc and get to the start up screen and DOS like features. The PC can see the two TomTom drives but when right clicking and going to properties the drive shows as used space 0 bytes and free space 0 bytes. I have all the required backups but cannot access the 920 hard drive to put these backups in any ideas/solutions would be much appreciated
Thanks

Sounds like the File Allocation Table is messed up.

As you have Backups, I would think you could try a re-format of the Drive.

You mention 2 TT drives, so assume that you also have an SD Card. I would take it out while you recover the Internal Memory, and do it separately.

Hi Oldboy,
Thanks, I have removed the SD Card, however when the 920 is hooked up to the PC in my computer it shows two drive letters even without the SD card in the 920, I am unable to re format the hard drive because when I right click on the drive I am told to insert disc. On properties it shows as 0 bytes used and 0 bytes free. I am told that I might be able to run diskmgmt.msc?

Do you have a Card Reader? If so you should be able to work on the SD Card first.

If you can get that working then it might be enough to flash the TT, and give you access to the Internal Memory.

Now put app and map on the SD card, the device goes one step further to the start up screen but no further.
Think I will have to playwith it more later on
Thanks for your help so far.
If anyone knows how I can get to view what is on the drive now the thing is corrupt or how I can get to format it and start again please let me know
Thanks

Hi Andy,
Thanks for the info, this is a fairly new unit (December) if I cannot reformat and use the internal drive it may have to go back for repair, any experience of repair times with TomTom? Although I suppose as it came from Dixons I will go down that route first.
The other issue I have noticed on various posts is the issue of map updates and transfering them to a new unit. I have paid for a year of updates from TomTom which are tied to this particular 920

On my PC the forst drive letter is the SD card slot, the second one is the internal memory. If you have no SD Card in the device and try and format the first drive letter then it will promnpt you to insert a disk.

Can you format the second drive letter allocated to the TT?

If not it is foobahed!

It is a very sick 920, both the first and second letter ask for a disk to be inserted. When the SD card is in the device it can be read as you say with the first drive letter, the second is having none of it so I cannot format the internal memory. The thing does work now I've put the backup on the SD card so it is useable, back to the PDA for now
Thanks for help so far

Repair times are quite quick for TOM returns, once they have agreed that the unit must go back for repair after working with u to resolve. My 920 has been back twice once for a faulty tmc aerial and the other for a brightness issue recently.

In both cases the turn around was a day - so in one day - fix another - and return the next. All postage and packacking is supplied by tom tom.
I doubt you will have any luck with Dixons.

Have you tried connecting the unit with tom tom home operational? Check for updates and it may reload the application. Or try a TOM TOM home restore if you have a backup taken via this option. I have just resored a backup to mine as TOM TOM repair returned the unit with a much older MAP than the unit went in for repair with Evil or Very Mad

and they had also wipped my own POI's etc.

Thanks for all the responses, I have tried a number of combinations and used it today via SD card which is OK. Learned a lesson or two as well I didn't set up the warn when near POI and the TMC was in no rush to update traffic 176 miles and still trying, never mind. Will check tomtom account and plug in 920 once more, I doubt it will work because the FAT has disapeared

I have indeed been in touch with Tom Tom support and have been asked to try a number of options, I can only do a couple of them because the internal memory of the 920 is not recognised. The PC knows there is something there and calls it 920 but the FAT is missing so the computer only knows there is 'something' but showing as 0 bytes free and 0 bytes used. So at this point I don't think there is much I can do other than continue with the Tom Tom support route.
I will have to wait until Monday now to see what there response is.
I have Windows 4 Windows backups (which are also backed up to another drive as well) and a Tom Tom Home backup as well

Clive,

Cannot comment on the problem you are experiencing, but I can give you feedback on warranty repair.

Last year I took a faulty 920T back to PCWorld who returned it to TT for repair. They decided the unit could not be repaired, and replaced it with a new 730! At that stage the 930 had been withdrawn Rolling Eyes

I had to be firm that even though the 730 was a newer model, I was losing too much additional functionality. After some negotiation with PCWorld they replaced it with a 920T from another store.

So if you do go down the repair under warranty route, make sure you get a like for like replacement Wink

To transfer the map update service, you will probably have to provide evidence to TT that the unit has been replaced under warranty. This may take some time. They will allow 1 new device on TT home in 6 months.
