unable to format usb stick ?strange things happening as well!!!
Hi all,

I have a pendrive that is fat formatted...
It was being detected so far on solairs...but now during the re-installation of solaris ,i did not remove the drive and guess i screwed it up...
since then , i am unable to use it...guess its now not formatted or is corrupt...
but the irony is ,when i insert it into xp,it says "not formatted"...
when i insert into soaris through a usb hub its not detecting....
nothing in /media/
but if i connect it to the physical port then it works ,and i can look into its contents...
again here also i am unable to install many pkg that i have in it...
get an I/O error!!!

First of all, how can this be possible?
secondly i tried formatting this using the rmformat and this is what i got!!!

bash-3.2# rmformat -l
Looking for devices...
    1. Logical Node: /dev/rdsk/c0t1d0p0
        Physical Node: /pci@0,0/pci-ide@6/ide@0/sd@1,0
        Connected Device: TSSTcorp CD/DVDW SH-S182D SB03
        Device Type: DVD Reader/Writer
        Bus: IDE
        Size: 681.6 MB
        Label: <None>
        Access permissions: Medium is not write protected.
    2. Logical Node: /dev/rdsk/c4t0d0p0
        Physical Node: /pci@0,0/pci1043,8234@2/storage@4/disk@0,0
        Connected Device:          USB FLASH DRIVE  PMAP
        Device Type: Removable
        Bus: USB
        Size: 984.0 MB
        Label: <None>
        Access permissions: Medium is not write protected.
bash-3.2# rmformat -F long /dev/rdsk/c4t0d0p0
Formatting will erase all the data on disk.
Do you want to continue? (y/n)y

bash-3.2# mkfs -F pcfs /dev/rdsk/c4t0d0p0

Device /dev/rdsk/c4t0d0p0 was assumed to be a diskette.
A diskette specific operation failed on this device.
If the device is a hard disk, provide the name of the full physical disk,
and qualify that name with a logical drive specifier.

Hint: the device is usually something similar to

/dev/rdsk/c0d0p0 or /dev/rdsk/c0t0d0p0 (x86)
/dev/rdsk/c0t5d0s2 (sparc)

The drive specifier is appended to the device name. For example:

/dev/rdsk/c0t5d0s2:c or /dev/rdsk/c0d0p0:boot


What does this mean, and why am i not able to format the usb stick?

it means you forgot to specify which partition to format, it seems that solaris is slightly different to what i've used but it seems to follow the syntax, computer (dev/)/ hub(rdisk/)/ USB drive (c4t0d0p0), i'd be willing to bet that it requires a specification of which part of the drive to format, also if windows recignises it, why not format it there?

Windows does recognize it but i want to try formatting from solaris....
As soon as i plug it in ,xp promptly detects and says it needs to be formatted...
Guess we should port the same thing over to solaris as well ;)

The error message is trying to tell you to specify a partition number and the manual page states it too.


mkfs -F pcfs /dev/rdsk/c4t0d0p0:c

thats what i was saying

jlliagre 06-03-2008 03:31 PM

Indeed. Your reply was missing the precise syntax though.

Person_1873 06-04-2008 08:48 AM

this is because im a linux user, not a solaris user ;)
