Downgrading a 16gig flash to 4gig

[dranreb]

Hi guys, so I recently bought 2 16gig flash drives. I have a Logic car media player but it only reads up to 4gig flash drives, higher than that it does not even "see" the flash drive when I plug it in. So I was thinking is it not possible to format the 16gig flash creating a 4gig partition that the media player will read? I googled it quite abit but cant find anything that seems to be able to do that... Has anyone ever tried this and is it possible? Any advice would be appreciated

I've never tried it, but this link might help.

You should be able to partition the drive in Windows, using Computer Manager -> Disk Management.

Here's a guide on how to do that: http://techpp.com/2010/01/19/how-to-partition-a-hdd-hard-disk-in-windows-7/

Find someone to swap with or just buy another. 4gigs are really cheap now.

Yep. I'll swap a 4GB. You near the /\/¯¯¯¯¯\/\ ?

Thanks for the advice guys, following the ehow instructions now. Will test it out tonight on the player. hehe lol i know a few people that will swop a 4gb for a 16gb. if it really doesnt work il just go buy a 4gig, one can never have too many flash drives... because i loose them really fast...

I think it does not pick up the drive because its SHDC, or high density. Not sure if formatting will work.

@Nerfherder - You might be right. I thought it can't read it because it can't address that much space with its limited processor or something(could be talking total crap) anyway i did some more digging and found this walk through (http://www.nokiausers.net/forum/sof...-your-memory-card-also-works-flash-disks.html) I followed it and now my flash reads as a 4gb flash... pretty cool. will check out tonight and see if it actually makes a difference to the media player. holding thumbs!!

You could be struggling with two possible causes to your problem:

1) The default allocation size must always be set to 512kb, otherwise you will have compatibility and performance problems.

2) larger size flash drives may require more electricity from the 5v USB port, in which case it won't read if there isn't enough power. This has mostly been sorted out now, but older flash drives will still have similar issues.

As for the 4GB limit, my radio MP3 player will only see up to 2GB officially, but 8GB works just fine. All depends on the flash drive, I suppose.

IME windows won't let you delete the partition on a Flash drive. I had to use linux to do that last time I tried it.
