What happened to floppy drive support?
by n2xssvv.g02gfr12930
I've been using a floppy boot disk as reserve if my HD boot fails, But
it appears floppy support as now been removed. Why? Then how can I
create an emergency media that is flexible enough to be updated as required?

Question on shredding a terebyte drive
by Dean S. Messing
I have a terebyte sata drive that I need to securely wipe clean. It
originally had 2 partitions. I deleted them using `fdisk', rebooted,
and then as root ran
shred -vz /dev/sdd
The drive is capable of about 60MB/sec, but shred is only "shredding"
about 25MB every 5 seconds according to its output. Since the default
number of passes is 25, this works out to about 5 days.
The `shred' process is running at 100% CPU, presumably computing
the special random patterns for erasure. Since I have 4 CPUs
would creating 4 unformatted partions on the drive and then running
something like:
shred -vz /dev/sdd1
shred -vz /dev/sdd2
shred -vz /dev/sdd3
shred -vz /dev/sdd4
in parallel cut my time? Would be just as secure?
Thanks

Alpine will not show attachments
by Tom Diehl
Hi,
I am running alpine-2.00-1.fc10.x86_64 on an F10 box. If I get a message with
an html or file attachment and I try to open it, I get an error that
"Firefox can't find the file at /tmp/img--46112.htm" The correct program opens
up but I always get the can't find file errors. If the message contains a URL
then it comes up and displays properly.
Does anyone know how to troubleshoot this problem?
Regards,

Upgrading : give me strength ...
by Beartooth
I've tried all the tricks on this list a/o the troubleshooting
site, over and over. I finally gave up : downloaded and burned a DVD --
and *still* hit the catch-22 error, with too little space in mnt/sysimage/
boot.
Now what?
Can I simply delete all of /boot, or everything in it? All of
grub.conf? Or what? It's going to be a royal pain if I have to burn all
my data to media, and then sneakermail that back onto each machine,
instead of just upgrading f11 ....

Enabling Airport wireless on Macbook Air with F12
by Colin Paul Adams
Thanks to Chris Smart, Peter Danenberg and others, I have been able to
install Fedora 12 as the sole O/S on my Macbook Air (first
generation).
However the wirless networking is not enabled.
I am following the instructions in
http://docs.fedoraproject.org/wireless-guide/f12/en-US/html-single/#chap-... .
There was no wireless device shown in the network Configuration, so I
clicked New and added a device for hardware Apple Airport.
I also tried adding wireless device on the Hardware tab (eth0), but although
it allows me to do this, after I save and then reopen the Network
Configuration, the hardware only shows a device pan0 of Type Ethernet
(which was there from the start). It does appear on the Devices tab
(it didn't originally until I added it), but has staus of inactive,
and no means to activate it.
However, even after restarting the computer, the wireless icon on the
panel says there are no network devices available.
So I tried removing the device from control by NetworkManager, and
activated it manually. But then I get:
Device eth0 does seem to be present, delaying initalization.
What do I need to do?

Problem with an external usb HD - slow usb
by Luigi Castro Cardeles
Hi list,
I use fedora 12 on a dell inspiron 1545 laptop.
(2.6.31.12-174.2.22.fc12.x86_64).
i have a external usb hd and i can't make it connect like a usb 2.0 device.
this device is ntfs format
I check if the device is using ehci (dmesg after i plug the device)
[root@localhost ~]# dmesg | grep USB
usb 2-2: new high speed USB device using ehci_hcd and address 2
I check if this device is connected on a usb 2.0
[root@localhost ~]# lsusb
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 015: ID 0471:2021 Philips
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I mount the device with this options:
/dev/sdc1 on /media/hd_backup type fuseblk
(rw,nosuid,nodev,allow_other,blksize=4096)
but when i use cp, mv or rsync, the max speed i get is max 6MB/s (a lot
800kB/s).
If i use this device on Windows (tested with Vista and Seven), i get much
high transfer rate.
I read about sync and async options, but if i put sync or async on fstab, it
does not alter the transfer rate.
Is this the normal upload transfer rate? I am doing something wrong?

Kernel boot problems or is my hard drive failing ?
by linux guy
If I power down my laptop via the usual KStart->Shutdown means, it can
take up to 4 restart attempts before it fully boots.
It has no problem launching grub and the kernel selection screen. That
it does reliably every time. After that, there are issues.
Twice I will get a back screen with a flashing cursor. Then I will get
an ehci -19 error. Then it will boot properly.
My fscks are fine. I had a block error once, about two weeks ago, but
that was with an older F12 kernel after completely crashing during a
resume from suspend to RAM.
Is anyone else experiencing a problem booting ? Does this sound like a
kernel problem or is my hard drive failing ?
Thanks
