16GB USB drive [Solved]

Postby Snowman » Tue May 27, 2008 2:49

I've recently purchased a 16GB USB thumb drive. Sabayon doesn't recognize the drive no matter what. Does anyone else have this problem? What is really odd is that no Linux distro is able to read it. Only Windows seems to read the drive. Any ideas?

I guess the pendrive is formatted in ntfs. If that's the case, you have two options:
1. Format it in ext3 (which is faster and more secure than ntfs) and add a driver for read ext3 in your windows.
2. Configure your fstab or hal.
Of course, my suggestion is the first option. :P

It has something to do with the size. I have my 4 GB thumb drive formated as NTFS and Sabayon automatically recognizes it.

Nonsense. Sabayon fully supports NTFS.

Do this:

Attach the USB, then get some info as root:
Code: Select all
dmesg | tail

and
Code: Select all
lsusb


P.S. are you testing Sabayon 3.5? Then i must move this topic to testing forums.

Thanks for all the answers.
Fitz, it's not a problem with automount since my other usb works fine.
DHalens, the drive is formatted as FAT32 so it's not an NTFS issue.
Joost, Yes I'm using 3.5 on my laptop but I also use 3.4 on my desktop and the problem is the same. I think Stupot has the same idea I have that it's due to the size. Here is the info you requested. It does the same thing in Knoppix as it does in Sabayon so I don't think it's related to Loop3. I ran the commands with both my 4 and 16 GB USB drives in.

Perhaps you misunderstood me (or I misunderstood you)? My problem was with the USB pen drive, not automount per se. The firmware in some pen drives has a bug in it. Low-level formatting the pen drive, then re-formatting it (high-level formatting) as FAT32, NTFS, etx2, etx3 or whatever you want, allows Linux to access it.

Sorry Fitz I misunderstood. I tried doing a format through dos and windows and it still didn't help. I'll try by booting off a LiveCD next but so far no livecd has recognized the drive. :(


Edit: I tried a format through several partition managers on Hiren's Boot CD and still nothing.

I think you've been performing high-level formatting, not low-level formatting? You need to use a different type of formatting software to low-level format a drive; see the SL Wiki article I mentioned earlier for details of a low-level formatter. GParted and other partition managers, MSDOS and Windows only offer high-level formatting.

I really thought that the Ranish partition manager and Partition Magic would be able to do a low level format. I guess not. I downloaded the utility on the page you suggested. Bad news is the software only works on Windows. Took a long time to do the format but it works now. So ..

Thanks Fitz.
