 Posted: Fri Sep 23, 2005 1:20 pm Post subject: Strange behaviour of memory stick |
 |
|
i am trying to setup a gentoo box here on a shuttle pc for a pal. the problem is i bought for him a cheap memory stick to use. now the following strange behaviour occurs which is a bit annoying (very annoying to be precise).
i enter the memory stick and after some time dmesg gives the gloriuos message it works. here the output for those interested

now i try to mount... due... /dev/sdb1 does not exist. it exists anything else from /dev/sdb2 upwards and /dev/sdb itself but just not /dev/sdb1. i then do 'mount /dev/sdb /mnt/memstick' which of course tells me it doesn't work as you can not mount the device itself but the partition. but exactly this makes the /dev/sdb1 suddenly appear out of nowhere and i can mount my memory stick and use it correctly. dmesg tells me the following during that actions.
| Code: | SCSI device sdb: 510208 512-byte hdwr sectors (261 MB)
sdb: Write Protect is off
sdb: Mode Sense: 03 00 00 00

sdb: sdb1
SQUASHFS error: Can't find a SQUASHFS superblock on sdb
FAT: invalid media value (0x01)
VFS: Can't find a valid FAT filesystem on dev sdb. |
my /mnt/memstick entry in fstab looks like this btw.
| Code: | | /dev/sdb1 /mnt/memstick vfat noauto,users,umask=007,fmask=117 0 0 |
any ideas why the /dev/sdb1 does not show up after inserting the memory stick but after doing an unsuccessfull mount of /dev/sdb ?

| Maybe the partition table on the memory stick is broken? You could try to make a new partition on it and format it. |

tried it, the same happens. funny is that i can plug in the stick, do a 'touch /dev/sdb' and then /dev/sdb1 suddenly exists...

| FWIW I have the same problem here. Still searching for a good reason for or answer to this. |

I have precisely the same issue with my I-Stick2 Model: IntelligentStick Rev: 2.00
I was using fdisk /dev/sdb and issuing q and it would make the device /dev/sdb1
Touching /dev/sdb is quicker, kinda, but I would certainly like to hear of a fix if one is found... |
