Format takes VERY long time
Hi all.
I'm tring to format an external USB hd on my Sun Blade 2000 WS.
The disc itself is attached to a USB 2 PCI card and the format says:
"Formatting cannot be interrupted
and takes 9188 minutes (estimated). Continue? yes"
My question is: have you ever experienced such a long time to format a
disc?
I believe this is a "low level format", but,... it is a LONG wait!
Thanks.
Kind regards.

For scsi disks the format command does nothing but data erase and test.
The format command is retranslated by the disk, one thinks a format is
executed.
I think it's the same for an ide/sata drive.
Low level formatting is no more, except for floppies.

How big is the disk? 9100 minutes seems a little extreme but if the
disk is 900 GB, it might just take that long to do a low level format.
It's rather unusual to have to do a low level format; it's usually done
at the factory and need not be repeated.

Saw something like that once on Windows, where the USB 2 flash disk was
plugged into a motherboard USB port, and those were restricted to USB 1
speeds.
In other words, it may be that for some reason your system sees the
disk as a USB 1 device. You say it's a USB 2 PCI card, does Solaris see
it as such?

Actually, the whole thing is very strange.
The disc itself is a normal 320Gb Lacie disc, and I used it for a long
time without any problem with this WS (my Blade 2000).
BUT, last week I unplugged it from the Blade 2000 because I needed to use
it on my Windows PC.
I had to reformat it to create an NTFS filesystem; after this
operation, I can no more format it with Solaris.
It is seen by the kernel, and indeed I can create a ZFS on it (it is very
fast, BTW) but I can no longer have it working via UFS + the automounter.
I don't know what to think.
P.S. I believe it is seen as a USB 2.0 device, in fact dmesg shows:

Format on M$-Windows is equal to newfs in unix, not format in unix.
The format you did for ntfs, just created a new filesystem not formatting.
Modern disk do not allow low-level format !, they try to fool the OS.
