write permissions on hd

[Captin]

My Gentoo box crashed on me the other night. when I restarted one of my file harddrives was missing. I checked my fstab and changed the permissions to ro after doing this my drive would show up after reboot. If I change the permissions back to rw the harddrive won't even show up in /dev or anywhere else for that matter. Any ideas?

Thanks

Which partition, i.e. where is it normally mounted?
What were the errors on booting it normally ?

You can remount a mounted drive on-the-fly if you need to:

[Captin]

my fstab line is:

/dev/hdd1 /mnt/media vfat users,owner,rw,umask=000 0 0

the boot up errors are:

fsck: Error 2 while executing fsck.Reiserfs for /dev/hda4
modprobe: Can't locate module /dev/hdd1
mount: special device /dev/hdd1 does not exist
some local filesystem failed to mount


I was bit torrenting a file to that hd when it crashed.

hmmm, seems like nobody has any suggestions.

Remounting the drive after boot seems to work fine. I can write to the drive and everything. however thats something else that I have to remember after boot everytime. If anyone has any ideas they would be greatly appreciated.

Thanks again

I do appreciate all your help. The drive in question is /dev/hdd1, the vfat labeled media. normally I have the permission as rw. Anyway here is my fstab:

GNU nano 1.2.1 File: /etc/fstab

# /etc/fstab: static file system information.

# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency). It's safe to drop the noatime options if you want and to
# switch between notail and tail freely.

# <fs> <mountpoint> <type> <opts> <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
#/dev/BOOT /boot ext2 noauto,noatime 1 1
/dev/hda1 /boot ext2 noauto,noatime 1 1
/dev/hda4 / ReiserFS noatime,notail 0 0
/dev/hda3 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 users,owner,noauto,ro,umask=000 0 0

/dev/hdb1 /mnt/media2 ntfs users,owner,ro,umask=000 0 0
/dev/hdd1 /mnt/media vfat users,owner,ro,umask=000 0 0

# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:

none /dev/shm tmpfs defaults 0 0

You did not follow my advice, then.

here once again is my fstab

If you say "users" works then that's how it is, of course; I don't remember it anywhere in my mount man page, oh well.

So does the boot-up mount still complain about the missing hdd1 ?

It's vfat, so fsck wouldn't be able to correct or even check it;

In fact, what it says is that the device node for hdd1 doesn't even exist - which is surely not true.

Or rather, it does exist (these are all sort of auto-generated for all possible HDs up to partition #20 or something), but there is no actual HD partition behind it - or so it says.

Compare it with the output from

O.k. here is what dmesg told me:

Well thanks for your help. I think I've fixed it.
I used scandisk on a window box and everything seems to be working.
I appreciate all the usefully thoughts and suggestions you had.
