UDF on a "non-removable" disk

I apologize in advance if I've posted to the wrong forum, or have missed something obvious.
I am trying to mount a UDF hard drive created in Linux on a Solaris 10 SPARC workstation (and will also need to do so on a Solaris 8 SPARC workstation). According to the Sun documentation (http://docs.sun.com/app/docs/doc/816-0222/6m6nmlt3m?a=view), I should be able to do this. However, when I try to issue the following command, I get the following errors:
mount -F udfs -o ro /dev/dsk/c0t8d0s2
mount: I/O error
mount: cannot mount /dev/dsk/c0t8d0s2
As far as background information is concerned, I'm using an IDE disk with a SCSI adapter on it. The hardware is not a problem, because I can put a Sun label on the disk, along with a UFS filesystem and everything is happy. If I try to create a UDFS filesystem on the disk, with or without a Sun label, the operation fails.
I think the problem is coming from the fact that the hard drive is not seen as a "removable" drive by Solaris, and so it never allows the use of the UDFS driver. I was going to try the old PPSD driver (http://fy.chalmers.se/~appro/ppsd.html) to fake it into thinking it was removable, but I can't find the source for it, nor have I received a response from the author yet.
Is there a way to set this up so I can mount the UDF disk? It has to be this way because my datasets are too large for DVD.
Thanks.

Thanks Miheal,
I had done the following and now it is resolved:
1. srvctl config database -d <dbname> -a
2. From the dependencies I found that this diskgroup is listed.
3. Took the list of diskgroup (from dependencies), removed this diskgroup entry and ran the following command:
srvctl modify database -d <dbname> -a "data_dg1, data_dg2, data_dg3"
4. started the instance and it worked

Receiving non system disk error when trying to install Windows 8.1 full version on Mac Mini

The windows partion has been created but when the mac mini reboots I receive a Non System Disk error. Press any key to continue
Please could someone assist with my problem

Thanks for that information, I removed all the external devices except the Superdrive.
Ran Boot camp again, created the MS Dos partition, and the mac restarted.

"Non-System Disk" Boot Camp Windows 7 on 5K iMac

I've been trying to install Windows 7 as a Boot Camp partition on my 5K iMac for a few days now. It's driving me crazy.
I've tried:
Installing from multiple different USB devices – all USB 2.0, 16gb or 32gb. I've tried 4 different sticks now. I just tried a Sandisk 16gb as someone here pointed out none of theirs worked except their Sandisk drive, but no luck with that either.
Using multiple different ISO's, all x64 – all Windows 7 but different versions (Home Premium, Professional, Ultimate). These are all downloaded from the Digital River sources.
I contacted Apple Support and they advised attempting the Boot Camp setup while in Safe Mode. With this method, I was unable to even begin the process as the error message 'Must be Windows 7 or higher' comes up instead. I'm pretty sure this is just because I can't mount drives in Safe Mode.
Here's what happens:
Format the USB drive with 1 partition, set it to Master Boot Record, FAT32.
Run Boot Camp Assistant.
I leave all three options selected: create USB, download Windows software from Apple, and then create the partition.
Select the x64 Windows ISO.
Select the USB drive. Actually, there are no other drives connected, so it just auto-selects.
Hit 'go'. Let it do its thing. It asks for a password twice during the process, and takes about 20 minutes.
I then create a partition. I've been using 96gb, but have tried going up to 128gb to see if that makes any difference. Nope.
iMac reboots when that's done. It sits there for a little while with the backlight on and a black screen, then shows "Non-system disk. Press any key to restart.".
I hit my head on the desk a few times.
I try restarting the iMac and bringing up the boot manager to see what disks are available. There's only one: Macintosh HD. No recovery HD, and no 'Windows' drive I've seen on some other posts.
I restart the iMac and let it try booting normally again. This time, and all subsequent attempts, I get a "No bootable disk" error.
At this point I find some sorta-relevant post that recommends trying something else, so I remove the partition and try that – a different USB, a different ISO (of the same thing). I do not have a disk drive of any kind and cannot use Windows that way.
I've updated to the latest version of Yosemite, but that changed nothing. I've also tried inserting the bootable USB in my rMBP 13", but that doesn't show it as a boot disk either.
Not sure if maybe I'm missing a step? I've been following Apple's step-by-step guide in their Support pages.
If anyone has any experience with this problem, any advice would be greatly appreciated.

Ok. I've created a Boot Camp partition, and WININSTALL is the USB drive I've created via Boot Camp Assistant.

Thanks for taking a look at this. I haven't been able to find a Windows 8.1 ISO to try as I don't have a license for that, only Windows 7.
Also, the USB stick I'm using now is a Sandisk Cruzer. I've seen it used elsewhere here with success, so figured it must be a suitable device.
Any ideas of what else to try?

Disable monitoring for non-system disks.

Hi all,
Our backup server dynamically mounts disks (with drive letters) when it's backing up a Virtual Machine.
These disks are giving a lot of alerts in our monitoring that we don't need, therefore we want to disable monitoring for these disks. What is the best way to disable monitoring for these non-system disks ? As I said, these disks are dynamically mounted and
unmounted ...
Any experience with this case ?
Kind Regards,
J. Monnens

This is a bit surprising, since the logical disk discovery only runs once a day, plus it's not supposed to discover network and removable drives.
That means that your disks are mounted when the discovery runs and that they appear as "real" logical disks...
Unfortunately there is no "sync time" parameter for this discovery, which would have allowed you to specify the time of the day at which the discovery runs; thus allowing you to set a time at which you know the drives are not mounted.
Is there any other parameter that could help identifying these specific disks, besides their letter, so you could add them to a dynamic group?
Otherwise, what you could maybe try is to create your own logical disk discovery based on the native one, but with specific settings that would exclude your drives and then disable the native discovery.
But this again implies that you have something that would let you identify specifically your mounted drives... Also the native discovery is a quite complex VBS, I wouldn't actually recommend disabling/modifiying it.
Maybe I could have another idea with more details about your environment...

Removed disk in Time Machine, now can't reselect to get my old backups back

I accidently clicked Remove Disk in Time Capsule on my MBA. Now when I try to reselect it in Time Machine (using the Time Capsule disk listed) it doesn't find my old backups.
I don't want to start again as there is all my old backups sitting on the Time Capsule taking up space. Any advice to get my backups back?
One thing I have noticed is the icon for the Time Capsule used to be the Wi-Fi 'fan', but now it's got the people holding hands icon instead. Sorry if they have correct names for the icons but that's the best description I can use. I also have no idea if this is important or not.
Thanks.

If you mean the TM Preferences window shows "None," it just hasn't updated the window yet. See #B3 in Time Machine - Troubleshooting

Ipod 160GB showing in Windows Vista OS as Removable Disk, not appearing in iTunes (latest version). How can I resolve?, Ipod 160GB showing in Windows Vista OS as Removable Disk, not appearing in iTunes (latest version). How can I resolve?

My Ipod 160GB when disconnected is showing without any files, but no room available. It appears in my 'Computer' screen as 'Removable Disk (though the icon is a little iPod). It does not show up in iTunes at all (I have the latest version).
When I right-click the icon on the 'Computer' screen it does run incredibly slowly. I was doing this to consider if I should try formatting it (only NTSF and exFAT formats were showing) but I wasn't certain if that would be a good idea.
I have thus far:
Hard Reset iPod
Verified the Apple Mobile Device USB Driver was installed correctly via Device Manager
Checked the device in 'Computer Management' > 'Disk Management - showing as a RAW file with only format option as exFAT or NTSF
Ran iPod in Diagnostic Boot Mode - IO > HardDrive > HDSMARTData* - stats revealed 'Error' (did this twice to confirm error). Reset iPod from here.
After this it actually came up in iTunes but said it needed to be restored - ran Restore iPod. Error message said 'iPod cannot be restored. Uknown error occoured (1415).
Tried Solution 1 (http://support.apple.com/kb/TS1539) - Reregistering the .dll files. Was unable to complete step 11 as the iPod did not appear in iTunes.
Verified that Apple Mobile Device Manager was installed.
Restarted the Apple Mobile Device Service.
Checked for third party conflicts - couldn't find any.
Changed the drive letter and restarted the computer.
Put into disk mode - unsure what that achieves.
Downloaded the HP USB with no luck running the program. I believe that Windows Vista doesn't allow formatting drives to FAT32 at all, and even previous editions of Windows wouldn't allow formatting above 32GB so certainly no suitable for me. If I got hold of a mac computer - could I format on that? Or is there a FAT32 Formatter that works for 160GB?
So I am at a bit of a frustrated loss. If you have any suggestions or know what I should do - I am all ears or eyes as it were. I will be on standby to give you more information if required.
Thanks,
Ashley

Try Resetting Your iPod while it's connected to the computer.
Hold down the Menu and Select buttons until you see the Apple logo (or Menu & Play/Pause in older models).
This will often get it recognized. It may take several attempts.
Also see these (if you haven't found them already):
Your Windows PC doesn't recognize iPod

The message means that your internal hard has been damaged. This message always comes up when the file system is corrupted. I suggest to remove it, connect the hard drive into a different computer as an external drive (use usb caddy), perform a backup if possible and the format the hard drive and restore the factory settings. I'm afraid that you have to reformat the hard drive, a checkdisk scan won't help..
The error message means that the Boot Sector is corrupt or has been damaged. It does not mean that the hard disk is damaged.
This is a fixable issue. There are a few command line tools that can be used.
You will need to make an appropriate version (32-bit / 64-bit) of the Windows 7 repair disc from a working Windows 7 installation. You will need either a USB or CD to create your rapair CD/USB. Follow the instructions on this video to create the repair installation of your choice..You will will be using the manual boot sector repair that is described in this video to repair your Windows 7 Boot sector. Use the Windows 7 repair disc or repair USB thumb drive that you created earlier to accomplish the repair.

IPod nano being read by Windows as "Removable Disk"

I have a 4gb nano, current firmware 1.1.1. Now, I've updated it before to the music on iTunes (back when it was on 1.0), but then one day, the iPod suddenly showed the exclamation/folder icon. So I restored the iPod with firmware 1.1 (it recommended I update, so I did), but my computer couldn't recognize the iPod. It kept showing a little baloon (I'm using XP) saying that the device could not be written to (only when I unplugged it, however). So, I thought that maybe it was just trying to write to it very slowly, but after leaving it there for a day, supposedly "writing" to the iPod, there were no results. I updated to 1.1.1, thinking that maybe 1.1 had a bug that caused this, but then I was confronted with the problem of nothing recognizing it at all. Windows now shows the iPod as a "Removable Disk", and when I double click it, it shows the loading mouse for about a minute; until it says
"E:\ is not accessible.
The Files or directory is corrupted and unreadable."
NOTE: I have NEVER used any third party software like linux or "hacked" my iPod.
So, after looking around, I followed the method here:
http://docs.info.apple.com/article.html?artnum=93716
Because I could see the device in My Computer but couldn't open it, and iTunes didn't recognize it.
However, it was not a success, so I tried the method here:
http://docs.info.apple.com/article.html?artnum=301343
But that also didn't work. I am now at a loss for explanation, can anyone help me? This is my mother's iPod, and she's leaving on a business trip in two days; I'd like to get her music back on it so she can use the iPod on the plane. Any ideas?

It wasn't being recognized by anything... including the updater. But after searching through other threads, I found that other people have had this problem as well; it seems the firmware is the prime target for the scre-up. Thanks, Benoa, for the steps! Although you've probably heard it enough times already.

Kernel_data_inpage_error & non-system disk error but everything running OK for a while

Hi,
can someone please help me out since I have a deadline in coming up and need my laptop to work properly!
I have windows 7 64bit running on a HP ProBook 6550b. My PC runs fine for about an hour, after an hour the screen freezes for 10 seconds and then I get the KERNEL_DATA_INPAGE_ERROR. He reboots and then I get the message 'Non-system disk or disk error'
Then I just shut down my PC and start it back up and everything works perfectly fine again for about 45 minutes. Then again the same problem.
I have tried multiple things. I executed a chkdsk /f /r This did find some problems. I tried and followed some instructions about changing the paging file settings. I ran a memtest. No errors with the memtest.
Finally I went in the BIOS and I did a HP harddrive test. This one failed almost immediately but I can just close the BIOS and start my PC and windows runs fine.
What can I do to resolve this problem other then buying a new harddrive. (I intend to buy a new laptop anyways in couple of months after I have passed my deadline and test period has finished. But for short term I really needs this to work.)
Many thanks!!
Johan

Just in case someone else encouters this.
The problem was due to my SSD M4 hard drive. There was a problem with the firmware causing hourly crashes after the disk has been in use for more then +-5200 hours. Upgrading the firmware fixed this for me.

Wow...I never thought there would ever be such a screwy problem like this on such a large scale....has anyone noticed how many similar posts have been posted in the last week or so? Not saying this never happens to anyone--in fact, it's happened to me beofre, but it was simple to fix...but the same problem happening with so many people at about the same time*...I don't know, it's kind of strange...anyway....
Yeah, I'm a Mac/Apple guy to the core, and have been since 7th grade (about 11-12 years now). Yet, I can't help but look at my iPod as if it has self-destructed. I was listening to it (w/ tape adapter, of course) on the way home in the car, then unplugged it for literally five minutes, got into my apartment, plugged it in my dell Latitude, and poof it had been reformatted. So, the moment I plugged it in, its funcionality basically vanished. The 5 R's have been useless thus far, and I can't even reformat using Explorer, because Windows tells me that the 1 GB iPod now has no storage capacity. ***? Strange, strange. Anyhow, sorry for the rambling, but this really confounds and frustrates me. APPLE....HELP US PLEASE!
*Don't get me wrong: I'm not a conspiracy nut; it's just hard to wrap my mind around this right now.

What file system format is the iPod formatted with? FAT32? To check, right->click on your iPod's from under Computer and choose Properties.
Have you tried to reformat it yet to see if that resolves the issue?

Non system disk error or disk error when turned on

I have a BIG problem with my laptop, it doesnt load my operating system! :dead:
I have a 100GB hard drive in my laptop and it was working perfectly fine until a blue screen came up and turned my laptop off!! I turned it back on and it came up with a message saying: ''non-system disk or disk error; Replace and strike any key when ready'' Before that, I have the RAM of 256MB . The RAM themselves had a test and showed no problem at all. When I did go into bios, it didnt give me an option where my laptop hard drive could do a self test, when it should have. So i decided to buy a new hard drive which was 160GB seagate. I put it into my laptop and had my Windows XP CD ready to put into my CD drive to install. BUT...........the same message came up ''non-system disk or disk error; Replace and strike any key when ready'' and didnt read my CD. It keeps doing it now and doesn't read anything from the CD SOMEONE PLEASE...............HELP!!!..................!!!! Does anyone know what I am talking about? If so, please help. Thanks

I kind of know but we really need to know what kind of laptop you are working on here. Seems like it is an old one with XP and 256 megs of RAM.

IPod not showing up in Windows or iTunes? Showing up as removable disk :F ?

I have a 5th generation iPod Nano and I have had it for about a year. I tried plugging the iPod into my computer (Windows), but my computer and iTunes do not recognize it. The first few seconds when I do plug in my iPod, I go to My Computer and I see my iPod with my name beside it, but after about 2 seconds, it changes to Removable Disk :F and then it disappears completely after another second. Last night, when I upgraded my iTunes version, the iPod connected fine, but today, my iPod has not been recognized at all. Help please?

Is this a usb drive?
It will probably never recognise that drive ever again.. Mountain Lion has this little bug where it cannot recognise some USB drives.. I don't understand it.. but it just happened to me and a quick google shows it is not uncommon.
Your backups are not lost.. they are just not accessible.. you need to plug the drive into a computer with a better.. older OS. Find a new USB drive that Mountain Lion can actually read.. and even write to.. and copy the files across.
