Default dd: end of device

I'm trying to UFS-format a disk, but whenever I try to use dd, I get this:

Code:
$ sudo dd if=/dev/zero of=/dev/da0 bs=1k count=1
dd: /dev/da0: end of device
1+0 records in
0+0 records out
0 bytes transferred in 0.000768 secs (0 bytes/sec)
It's a PATA drive connected via an IDE-to-USB adapter. What could be wrong?

First of all, why are you trying to zero the device in the first place? that's entirely unrelated to "formatting" a partition with a UFS file system.

As for the dd issue, seems rather obvious... are you sure you're using the correct device node? post your dmesg.

I'm trying to zero the device because that's what the handbook says adding disks:

I see now, didn't notice the count argument... it's removing any existing MBR/PBR data.

Regardless, I ask again, are you sure /dev/da0 is the device node you should be using... if it is, it could be a defective USB->IDE controller, I've seen quite a few of them in my time.

Hmm. Could it be defective even if I'm able to use it well under Windows?

Potentially, some hardware manufactures design their hardware to be supported with vendors implementation of standards, not the standards themselves.. which results in "quirky" hardware.

On OpenBSD, one the first USB enclosures I bought didn't work.. I could read, but not write to devices attached to it.

It did however, work fine on a OS X system.. and the enclosure I bought after, with a JMicron chipset - worked fine.

Again, best post the dmesg... just to be on the safe side.

But it also states 0 bytes were transfered, which sort of leads me to believe the write was unsuccessful.

Agreed? be a little nicer.

Most likely. It could really be a defective adapter.

What do you mean by "be a little nicer"?

That was related directly to me. (I removed post because of my stupid reading mistake).

Oh, nice, my stupidity can be found in google cache .

Oh. OK. I'll try getting another adapter, or get a drive enclosure and see if it works.

First, test if it works in linux, or in some other unix clone - just to make sure that it is not FreeBSD bug.

Are you sure you don't need /dev/da0s1 or something?

What happens if you vary the size of the block (bs=512) or the count (count=2)? It could just be that the block size you specify doesn't match with the block size of the USB transfer and/or the SCSI/atapicam transfer and/or the block size of the HD.

In the various gmirror how-tos, it specifies bs=512 and count=10, which overwrites the first 5 KB of the disk. Lots more than the MBR and boot blocks.

However, you don't really need to zero those out to add a new disk to a system. Just slice it (and/or partition it), and format it as needed

I haven't tried that yet. It would take me two days to get to that adapter again, but yes I'll try your suggestions. I'll post updates as soon as I get to it.
