Can't get more than 2 partitions on 16gb Flashdrive using Deneb

[save2600]

A flashback to the days when we had bad luck using greater than 4gb HD's on our Amigas. BUT... I'm running OS3.9+BB2, NSDPatch and cannot get the Deneb card to fancy the 16gb flashdrive I just bought. For starters and very odd, (HDToolBox from OS3.9) after installing and partitioning the flashdrive as an Amiga hard drive and re-boot, the NDOS: icons do not come up that would normally allow me to format and be done with it. So... I go into the CLI and manually format what I know is really there. Great, so the 1st two partitions (6gb or less total) I can get icons for, but when trying to format a partition beyond UDH1 or a larger than 5gb partition, the card pauses for a long time before I finally get the error that it's not a valid DOS disk.

I've tried editing the NSDPatch.cfg by inserting the usbscsi.device in place of some other lines. Nadda. Does something have to be inserted in startup-sequence in order for Deneb to like larger GB flash drives?

TD64 claims that usbscsi.device already supports the TD64 commands  :-(
Anyone have any other ideas?

Thanks for the tips fellas. I tried HDinstTools and that allowed a DOS format on the partitions that HDToolBox would not, BUT even if I didn't get checksum errors... same result. Icons never pop up and even the CLI does not recognise them. It's as if my OS thinks it's an older version or something!

Monkeying around with the settings in Poseidon through all this, I even lost the ability for ANY flashdrive icons to pop up! Same with the CLI. They just don't exist anymore. I have no idea what I changed that yielded this worthless result, but it doesn't matter as that was on a different drive.

Anyway, I'm starting to think TD64, NSD, etc. needs to be flashed to the Deneb...

I did and found it was no smarter than FFS   :-)

Tried every combo suggested so far. Deneb or Poseidon does not want to properly deal with a flashdrive larger than 6gb apparently.

No PeeCee's here my friend!  But to answer your question... I have had in the past, had to format a flashdrive using the Fat system (on my Mac) before it would work on the Amiga. Getting the Amiga to recognise the flashdrive enabled it to be formatted then. ALL of the flashdrives I've ever worked with were 4gb or smaller though.

I'm currently formatting the entire 16gb flash the slow way and it seems to be taking. For now anyway. I have already gotten bad checksums on other partitions when going slow, but so far so good. I've even gone into the setup of the drive and changed values there. For instance, HDToolBox thinks this Flashdrive has 5 heads while HDInstools says 1. I rearranged the values to make more sense ala HDInstools, but not sure if that made any difference.

ROTFLMAO! Fake memory sticks?!? What's next? lol    I purposely bought this one because it said it was a U.S. sale and the feedback was good...

ePay linky to the one I bought and might have been duped by!

-edit-

Sure enough, the full format failed too. I'm testing it on the Mac right now... stay tuned to see if I've been gypped! lol

Are the TD64 commands built into the architecture of the Deneb then? I tried placing it in the flashrom, but Poseidon speared me and said it probably wasn't a valid application or didn't have a PSDROM tag or something like that...

@Platon42:

Thanks for the info and tips Chris. Glad you never tire of re-writing some of this stuff. lol  I did see a relatively recent discussion where you were talking about TD64/large GB usage with the Deneb, but thought it strange I couldn't get mine to work.

@Marc & rest:

Looking at the envelope it came in, stamped with ink is a Max Fong of Oakland Gardens, NY. Package was sent from Flushing N.Y., but it's really starting to seem as if this particular flash drive *IS* counterfeit or junk. I'm even getting flaky results writing/reading from it on my Mac now. Journaled or Fat, doesn't matter. I copied 14gb worth of data to it from my Mac and then stuck it in the Amiga. There were some files that were clearly missing on the Amiga end, even though OS3.9 properly recognises its purported size and remainder of disk space. I then tried to dump the 14gb contents back to my Mac and got a "you don't have enough privileges" after a while and then the Finder tanked. Had to reboot. If I format as Fat and leave it empty, the Amiga sees it as a 16gb flashdrive. I'm still putting it through some tests though to see if I will be able to use it as a simple flashdrive that way (not a "real" HD) and keep my 128mb Flash as just my bootable 3.9 disk. But again, the evidence here is proving that I was duped. lol

I have asked the seller for my money back. Failing that, I guess I could always scratch the '1' off of '16gb' as 6gb seems to be the usable legitimate space  :lol:
