Persistend device in disk/by-path disk/by-uuid but no in disk/by-id
I have a cell phone with embedded memory and a memory slot with Memory Stick Micro (M2).
Embedded memory is 'connected' as sdb and MemoryStick as sdc.
Both of them appear in /dev/disk/by-path/ and in /dev/disk/by-uuid/.
But not in /dev/disk/by-id/ which would be most suitable for me.
$ ls -l /dev/disk/by-path/

when you insert a device, it gets a device name,. i.e sd[a,b,...][1,2,...];
this is an automatic name dependent on the order of insertion/detection.
a fs / disk label, is embeded into the partiton's filesystem, so when you insert the device, it can be detected and the device is avaialble
by that name under /dev/disk/by-label
e.g
e2label /dev/sda13 ZeroSpace
would result in /dev/disk/by-label/ZeroSpace when the device is inserted.
so you can mount it by that name every time, instead of having to figure out where the device
-node(sda13) actually is

Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)
Hello,
I tried to re-install de OS from windows 7 to windows 8.1 and when the bios update driever was installed and the laptop was restaring it appeared the folowing window and message:
Boot Device Not Found Please Intall an Operating system on your hard disk. Hard Disk - (3F0)
After that i tried a lot of different ways to get to boot device select ...but i couldn't do anything. I removed the HDD and i put it back, i've tried with holding in the same time windows +B and pressing the power button in the same time for 1..2 seconds and then i've waited for at least 1 minute..and it didn't appeared anything on the screen. I've done the hard drive check and it passed. The weirdest thing is that when i want to select a boot device to re-install again the OS, i can't see any boot device to select. I need to mention that i've formatted the HDD in another computer. I dont care about the informations from the HDD beacause i saved all the informations on another device storage.
Please help me repair this problem!!! thanks a lot!
Have a nice evening.!!!Whenever you get a message stating that the boot device not found it could be because of bad sectors on the Hard Drive. Its not necessary that the Hard Drive Test should fail to determine if the Hard Drive if its faulty or not. Sometimes even if the Hard Drive Test passes the Hard Drive will still not work because of the bad sectors in it.
Best way to find out if its the Hard Drive you can try the Hard Deive on a different Notebook which would help you determine if it's faulty or not.
Could be due to Application or driver conflicts, virus issues, file corruptions due to incompatible applications, improper shutdowns, update failures due to conflicts, sudden power surges, if notebook is dropped etc..
HP will provide a replacement Hard Disk Drive if the Notebook warranty is Active, If not you need buy a SATA Hard Disk Drive from a retail shop nearby
Please make sure you are getting at least equal capacity as the original one in order to use Recovery Disks. If you need you can buy a larger, but not smaller capacity Hard Disk Drive. For example if you have a 500GB Hard Disk Drive you can upgrade it to 750GB Hard Disk Drive but not 320GB Hard Disk Drive
Please try the below shown troubleshooting steps once:
Step 01. Remove the battery and unplug the AC/Power Adapter
Step 02. Press and hold the Power button for more than 30 Seconds
Step 03. Plug in the AC/Power Adapter (leave the Battery out for now)
Step 04. Press the Power button and check if the Unit works normal
If the above mentioned steps does not help, then you can try reseating the Hard Drive on your Notebook
If the issue persists again please Contact HP if your HP Notebook is under warranty, HP would replace the Hard Disk Drive and provide you a Recovery media to restore factory operating system after replacement (if you've not yet created Recovery Discs/USB Media)
Note: Back up all the personal data to an external drive if it's possible. Otherwise you could connect the failed HDD via SATA to USB adapter with another PC or same PC after replacement of HDD & re-installation of OS and try copying /recovering the files.

Backup DB with dynamic sql - want to substitute in dbname and disk file path
Re: Backup DB with dynamic sql - want to substitute in dbname and disk file path
Hope I can explain this. Below is a small snippet of code. I want to set @SQLTemplate_TSQL once at the top of the script and then execute the SET @SQLCommand and sp_executesql in a loop that reads a list of databases. It all works, except for the

WS-C6509-E not supporting 256 MB disk. upon inserting message pops up but "no such device" error comes when runing "sh disk0/1:"

Its working fine with 128 MB Diskbut my 128MB disk is working fine in both SUP and both slots..
And this only proves that the PCMCIA slot is not at fault. So this means that:
256mb PCMCIA card is dead; or
256mb PCMCIA card is not standard (non-Cisco)
I do not believe the 256 mb PCMCIA card is not working because it's not formated. Even if it's not formated properly the error message would've been different. -
Server 2012 RC. I'm using Storage Spaces, with two virtual disks across 23 underlying physical disks.
* First virtual disk is fixed provisioning, parity across 23 physical disks: 10,024GB capacity
* Second virtual disk is fixed provisioning, parity across the remaining space on 6 of the same physical disks: 652GB capacity
These have been configured as dynamic disks, with an NTFS volume spanned across the two (larger virtual disk first). Total volume size 10,676GB. For more details of the hardware, and why the configuration is like this, see: http://social.technet.microsoft.com/Forums/en-US/winserver8gen/thread/c35ff156-01a8-456a-9190-04c7bcfc048e
I'm copying several TB from a network share to this volume. It is very slow at ~12MB/sec, but works. However, three times so far, several hours in to the file copy and with plenty of free space remaining, the 10,024GB virtual disk is suddenly taken offline.
This obviously then fails the spanned volume and stops the file copy.
The second time, I took screenshots, below. The disk (Disk27) is marked offline due to "This disk is offline because it is out of capacity". And the disk in the spanned volume is marked as missing (which is what you would expect when one of its member disks
is offline).
I can then mark the disk (Disk27) back online again, and this restores the spanned volume. I can then re-start the file copy from where it failed. There doesn't appear to be any data loss, but it does cause an outage that requires manual attention. As you
can see, there is plenty of space left on the spanned volume.
Each time this has happened, there are a few event 150 errors in the System event log: "Disk 27 has reached a logical block provisioning permanent resource exhaustion condition.". Source: Disk.

This error seems to be related to thin provisioning of disks. I found this:
http://msdn.microsoft.com/en-us/library/windows/desktop/hh848068(v=vs.85).aspx. But both these Virtual Disks are configured as Fixed, not Thin provisioning, so it shouldn't apply.
My thoughts: the virtual disk should not spuriously go offline during a file copy, even if it was out of space. And in any case, there is plenty of free space remaining. Also, I don't understand the reason for why it is marked as offline ("This disk is offline
because it is out of capacity"). Why would a disk go offline because it was out of thin capacity, rather than just returning an "out of disk space" error while keeping it online.Interesting Thread, I've been having the same issue. I had a failed hardware RAID that was impossible to recover in place, so after being forced to do a 1:1 backup, I find myself with 5 2TB hard drives to play with. Storage Spaces seemed like an interesting
way to go until I started facing the issues we share.
So my configuration is A VM Running Windows Server 2012 RC with 5 Virtualized Physical drives using a SCSI interface, 2TB in size that make up my storage pool. A Single Thinly provisioned Disk of 18 TB (using 1 disk for parity)
Interestly enough, write speed has not been an issue on this machine (30~70MB/s, up from 256k on the beta)
Of note to me is this error in my event log 13 minutes before the drive disappeared:
"The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time.Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied."Source: volsnap, Event ID: 25, Level: Error
followed by:
"The system failed to flush data to the transaction log. Corruption may occur in VolumeId: E:, DeviceName: \Device\HarddiskVolume17.(The physical resources of this disk have been exhausted.)"Source: Ntfs (Microsoft-Windows-Ntfs), Event ID: 140, Level: Warning
I figure the amount of space available to me before I start encountering physical limits is in the vicinity of about 7TB. It dropped out for the second time at 184 GB.
FYI, the number of columns created for me is 5

Burned DVDs won't mount/read but seen by Disk Utility as containing data
Hi,
I've got a problem. I have about 200 burned DVDs which were created using my LG VHS/DVD recorder/player. I have used these same DVDs to burn from my external LaCie DVD buner with my PPC G5 running Tiger and my LG Blu-Ray burning with my MacBook running Leopard and those burns plays fine on all 3 devices. However, neither the LaCie DVD burner nor the LG Blu-Ray burner seem able to read/mount the DVDs created with the LG VHS/DVD recorder/player although the G5 and the MacBook, both using Disk Utility, can see that there is data and the size of it on each disk. I am also unable to create a disk image for some reason as it begins but halts saying there's an I/O error. I need to get the content of these disks onto Hard Drives to rip and encode. How do I get the computers to mount these disks which they clearly see are not blank?
Thank youTry opening them with mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you may also need the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/
which is a mere $20.
You should be able to convert them to mpeg2 which is the standard format of a video DVD. -

Csound1, William & Sig .... thanks for taking the trouble to reply. I fear you are right - I'll need a new disk. I'm booked in at the Apple Genius Bar in Bordeaux, France on Wed ... quite a challenge as my French isn't great! The current internal disk is 500gb, does anyone know whether I can upgrade my 21.5" iMac (circa Oct-2009 vintage) to a larger size internal disk, 1Tb or even 2Tb? I already have one external 2Tb drive and another one on order (I have masses of media stored and more planned as I've just taken up photography). Seems a bit of a pain managing with only 500gb internal storage. OR, can you advise me on how I can store all my photos on my new 2Tb external drive - I can't seem to figure out how to set the path for iPhoto to see them (I can't even figure out where they are stored right now!). Same with iTunes, how do I set the default storage to the external drive (I moved everything manually and then imported them all from the new drive - it worked but seemed very convoluted). Any advice on how to manage multiple drives gratefully received. And thanks again for previous replies.

AppleRAID enable: The target disk must be an existing volume, not a whole disk
I have a Samsung 750 which failed to spin up a time or two the past year. Scrounging I found a Seagate 750. Seeing as how I have plenty of drive bays I think the right thing to do is bind the Samsung and Seagate into a mirrored RAID. This volume is used for Time Machine.
Did similar to my Mac Mini Snow Leopard Server when it was new without wiping the original filesystem. But can't get there from here today following similar instructions.
The Samsung is disk2, Seagate is disk1. In Terminal.app I start with:
% diskutil appleRAID enable mirror /dev/disk2
The target disk must be an existing volume, not a whole disk
Blah. Perhaps this helps? Is essentially the same as the 320GB system drive as formatted by Apple:
% diskutil info disk2
Device Identifier: disk2
Device Node: /dev/disk2
Part Of Whole: disk2
Device / Media Name: SAMSUNG HD753LJ Media
Volume Name:

Is it so hard to follow through? you were to have backup already, clones are best, then erase/format and restore.
Then partition.
Some have been able to use Disk Utility booted from OS X DVD or another drive, and repair the drive.
You have to use Boot Camp Assistant (99.9% anyway) to create and achieve a proper Windows Master Boot Record partition. -
System Image Restore Fails "No disk that can be used for recovering the system disk can be found"
Greetings
- Our critical server image backup Fails on one
server -
Two 2008 R2 servers. Both do a nightly "Windows Server Backup" of Bare Metal Recovery, System State, C:, System Reserved partition, to another storage hard drive on the same machine as the source. Active Directory is on the C: The much larger D: data
partition on each source hard drive is not included.
Test recovery by disconnecting 500G System drive, booting from 2008R2 Install DVD, recovering to a new 500G SATA hard drive.
Server A good.
Server B fails. It finds the backed-up image, & then we can select the date we want. As soon as the image restore is beginning and the timeline appears, it bombs with "The system image restore failed. No disk that can be used for recovering the system
disk can be found." There is a wordy Details message but none of it seems relevant (we are not using USB etc).
At some point after this, in one (or two?) of the scenarios below, (I forget exactly where) we also got :
"The system image restore failed. (0x80042403)"
The destination drive is Not "Excluded".
Used diskpart clean to remove volumes from destination drive. Recovery still errored.
Tried a second restore-to drive, same make/model Seagate ST3500418AS, fails.
Tried the earliest dated B image rather than the most recent, fail.
The Server B backups show as "Success" each night.
Copied image from B to the same storage drive on A where the A backup image is kept, and used the A hardware to attempt restore. Now only the latest backup date is available (as would occur normally if we had originally saved the backup to a network location).
Restore still fails. It looks like its to do with the image rather than with the hardware.
Tried unticking "automatically check and update disk error info", still fail.
Server A SRP 100MB C: 50.6GB on Seagate ST3500418AS 465.76GB Microsoft driver 6.1.7600.16385 write cache off
Server B SRP 100MB C: 102GB on Seagate ST3500418AS 465.76GB Microsoft driver 6.1.7600.16385 write cache off
Restore-to hard drive is also Seagate ST3500418AS.

"If your destination disk has a lower capacity than the source disk, you need to go into the disk manager and shrink each partition on the source disk before restoring." Doesnt apply here.
http://benchmarkreviews.com/index.php?option=com_content&task=view&id=439&Itemid=38&limit=1&limitstart=4
for 0x80042403 says "The solution is really quite simple: the destination drive is of a lower capacity than the image's source drive." I cant see that here.
Thank you so much.Hello,
1. While recovering the OS to the new Hard disk, please don't keep the original boot disk attached to the System. There is a Disk signature for each hard disk. The signature will collide if the original boot disk signature is assigned to the new disk.
You may attach the older disk after recovering the OS. If you want to recover data to the older disk then they should be attached as they were during backup.
2. Make sure that the new boot disk is attached as the First Boot disk in hardware (IDE/SATA port 0/master) and is the first disk in boot order priority.
3. In Windows Recovery Env (WinRE) check the Boot disk using: Cmd prompt -> Diskpart.exe -> Select Disk = System. This will show the disk where OS restore will be attempted. If the disk is different than the intended 2 TB disk then swap the disks in
correct order in the hardware.
4. Please make sure that the OS is always recovered to the System disk. (Due to an issue: BMR might recover the OS to some other disk if System disk is small in size. Here the OS won't boot. If you belive this is the case, then you should attach the
bigger sized disk as System disk and/or exclude other disks from recovery). Disk exclusion is provided in System Image Restore/Complete PC Restore UI/cmdline.
5. Make sure that Number and Size of disks during restore match the backup config. Apart from boot volumes, some other volumes are also considered critical if there are services/roles installed on them. These disks will be marked critical for recovery and
should be present with minimum size requirement.
6. Some other requirements are discussed in following newsgroup threads:
