USB Flash drive not recognised

I'm currently at my daughter's place in Melbourne (actually I'm back in Perth, but I wrote this post while still in Melbourne). She has a '3' 3G USB modem, but I was unable to get it to work with Puppy. Perhaps I need the APN, which I can't find documented anywhere.

So, I am using her computer to access the Internet. I downloaded a couple of files and saved them on her Kingston Datatraveler 4GB Flash drive, but got a surprise when I plugged it into my laptop --- Linux does not recognise it, not at all. There is no kernel uevent generated when it is plugged in. Same situation with alpha9 and 4.1.2. I plug it into my daughter's laptop, Windows recognises it.

Hmmm. I still have XP installed on my laptop, will try that... no, it still isn't recognised. That sure is weird. I have a 2GB Datatraveler at home, that works fine.

I have brought a 2GB Lexar Flash drive with me to Melbourne, but it has a ext2 partition. So, I reduced the size of the partition and created a fat32 second partition.
Booted XP, but Windows has dissappointed me (again), the fat32 partition is unusable. XP sees a "G:" drive, however assigns that to the ext2 partition and will not assign any letter to the second. I dug deeper and found that it does see the two volumes but I could not make it use the second fat32 partition.

So, can't transfer any files from her laptop. Oh well, I'll email them to myself. These blog posts that I am typing on my laptop will not get actually posted until after I get home.

On a separate issue
Barry, I always thought pupsave backup was rather tedious; as a result it rarely got done. I have cooked up a small mod to the shutdown script that generates a backup copy (and keeps a few older copies) of the pupsave after it has been unmounted. Since it happens at shutdown it takes no more user time. I no longer have to boot pfix=ram to back up my pupsave! If you are interested in this for Puppy 5 let me know.

Tried Gparted?
Kingston Datatraveler 4GB Flash drive.

Just out of interest Barry did you try
GParted....see if it could see those drives...
select Boot and LBA flags
and then see if Windows sees it and also Puppy.

I have had the occasional boot where I
generally pick Xvesa but the computers
I have tested prefer Xorg - and I get
the no drive dramas.

Probably superflious to you but in the
midst of oddities these things can crop
up and the basics are forgotten.

Also some USB ports can act up.
I have a cheapie Asus MB on one computer
and only the rear ones consistently work.

Some Compaq laptops were well known for
poor USB performance.

I've seen the same issue with USB dongles
from 3 Mobile, needed to use 2 ports at
once as not enough power to the USB dongle.

And as is the way I can't find a referance for you today..re this issue. Sorry.

Enjoy your hols Big Fella.

Chris.

Datatraveler
I am running 412 from a 4GB Kingston Datatraveler. I used gParted, formatted to ext3 and marked it bootable. I also have a 2GB and a 16GB Datatraveler and they all work perfectly on an eMachines R3350. However, I once did buy a 2GB Kingston Datatraveler that was dead from the beginning.

FAT
I had that too in the past -- the FAT partiton has to be at the beginning of the drive... yet another example of the great "flexibility" of Windows.

Sony USB stick
Old Fujitsu Scaleo, into which I added a Sony 2G stick. It is only detected when inserted to main PC board that has USB 1.1 capability. If plugged to cheapo USB 2.0 card, inserted afterwards, it is not detected. Now I wish to have 3G dongle work from this cheapo USB card. I foresee that it might be problematic. Look at rerwin's thread on the subject for more.

USB...careful out there
Barry:

Please be very careful with your USB in Windows.
There are some dreadful viruses around helped by the availability of USBs.

“DJ Nikos writes...

hold down shift key and while holding down shift key put in the

That’s handy…….
But then I read in a later post:

I also saw this on Whirlpool about the
Free Panda USB Vaccine

http://forums.whirlpool.net.au/forum-replies.cfm?t=1209692

This only works for Fat32.

“””””””””””
And on the Panda page:

“The free Panda USB Vaccine can be used on individual USB drives to disable its AUTORUN.INF file in order to prevent malware infections from spreading automatically. When applied on a USB drive, the vaccine permanently blocks an innocuous AUTORUN.INF file, preventing it from being read, created, deleted or modified. Once applied it effectivelly disables Windows from automatically executing any malicious file that might be stored in that particular USB drive. “

“Simply and light-weight application that

As I’m fixing XP comps all the time these utilities are very handy.
Gave 5 USBs the Panda fix.
Then scanned them again.
