Path to main disk drive

when I right click mange on computer it says cant find path to HP (C:) drive?

Hi,
I offer, going to run menu and type this test "compmgmt.msc" or Enter this part in your Address bar : %windir%\system32\compmgmt.msc /s
If don`t open any things, I offer :
1- restart your system
2- press F8 key on keyboard
3- Enter to windows by LAST KNOW GOOD CONFIGURATION...
ALSO, you can use Backup and Restore system!
Good luck!
Future is mine!

Cloning a bootable disk drive

Hi.
I'd like to know if there's any way to clone my main disk drive (the one which contains the operating system) in order to have a backup of all my data to use it when necessary... I've been thinking about using a dd in single user mode, but I'm not sure if this will work, so I'd like to know if there's a better way to do this. I'd really appreciate any help, thanks in advance.

Hello,
As mentioned by mlhardwicke :
Ufsfump
/usr/sbin/ufsdump 0uf - $ROOT | (cd $BACKUP; /usr/sbin/ufsrestore ryf -)Install boot block on root partition :
/usr/sbin/installboot /usr/platform/`/usr/bin/uname -m`/lib/fs/ufs/bootblk $BACKUP

How do I restore from time machine backup onto unmounted disk drive "disk0s2?" :-(

In trying to restore my MacBook Pro after a strange freeze, I seemed to have unmounted the main disk drive. So, I have no drive on which to restore my computer using my time machine backup. What do I do now???

Give this a try:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
See if you are able to get the partition to mount. If not select the Terminal from the Utiilities menu. At the prompt enter:
sudo mount disk0s1
Press RETURN and authenticate. Your password will not be echoed. Press RETURN again. I'm assuming you have a disk with one partition. If that's not correct, then do not use the above command.

How do I make a bootable hard drive clone of my main disk in my mac pro?

Hi everyone,
How do I make a bootable hard drive clone of my main disk in my mac pro?
My main drive has bad sectors and I want to replace it.
Thanks in advance

Also your Mac's Disk Utility can make a bootable clone;
http://macs.about.com/od/backupsarchives/ss/diskbackup.htm
Consider though, if your internal HD is failing and defective, then any clone however made, may carry that defect.
Perhaps it would be better to copy your personal data, photos emails etc, to an external drive as well, just in case the clone did not work because of the failing hard drive.

SATA hard disk driver

hi
i got a SATA1 hard disk from toshiba model mk2555gsx and when i try to install any operating system it says it cant find any disk installed, my laptop is gateway model m-6804, i´ve donwloaded SATA drivers for my laptop ad it doest work, and i dont find hard disk driver from toshiba, please a dont know what else to do. thak you

First go into the bios and verify that the hard drive is recognized by the bios. If it isn't, then you either have a defective hard drive or a defective motherboard controller. According to the specs on that Gateway model it uses the same chipset that a lot of Toshiba Laptops use so it should support that hard drive. Please note that while Vista and Windows 7 have built in support for SATA hard drives, XP and Windows 2000 do not and will require integrating the SATA drivers into the XP install disk. ME, 98, and all previous versions of Windows do NOT have ANY support for SATA and will NOT work with SATA period.
Next, Toshiba's Hard Drive Support is located at http://sdd.toshiba.com/main.aspx?Path=ServicesSupport/TechnicalSupport This forum is ONLY for Toshiba Laptops and Projectors.
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

Comparison of SSD with hard disk drives

Attribute or characteristic
Solid-state drive
Hard disk drive
Spin-up time
Instantaneous.
May take several seconds. With a large number of drives, spin-up may need to be staggered to limit total power drawn.
Random access time[45]
About 0.1 ms - many times faster than HDDs because data is accessed directly from the flash memory
Ranges from 5–10 ms due to the need to move the heads and wait for the data to rotate under the read/write head
Read latency time[46]
Generally low because the data can be read directly from any location; In applications where hard disk seeks are the limiting factor, this results in faster boot and application launch times (see Amdahl's law).[47]
Generally high since the mechanical components require additional time to get aligned
Consistent read performance[48]
Read performance does not change based on where data is stored on an SSD
If data is written in a fragmented way, reading back the data will have varying response times
Defragmentation
SSDs do not benefit from defragmentation because there is little benefit to reading data sequentially and any defragmentation process adds additional writes on the NAND flash that already have a limited cycle life.[49][50]
HDDs may require defragmentation after continued operations or erasing and writing data, especially involving large files or where the disk space becomes low. [51]
Acoustic levels
SSDs have no moving parts and make no sound
HDDs have moving parts (heads, spindle motor) and have varying levels of sound depending upon model
Mechanical reliability
A lack of moving parts virtually eliminates mechanical breakdowns
HDDs have many moving parts that are all subject to failure over time
Susceptibility toenvironmental factors[47][52][53]
No flying heads or rotating platters to fail as a result of shock, altitude, or vibration
The flying heads and rotating platters are generally susceptible to shock, altitude, and vibration
Magneticsusceptibility[citation needed]
No impact on flash memory
Magnets or magnetic surges can alter data on the media
Weight and size[52]
The weight of flash memory and the circuit board material are very light compared to HDDs
Higher performing HDDs require heavier components than laptop HDDs that are light, but not as light as SSDs
Parallel operation[citation needed]
Some flash controllers can have multiple flash chips reading and writing different data simultaneously
HDDs have multiple heads (one per platter) but they are connected, and share one positioning motor.
Write longevity
Solid state drives that use flash memory have a limited number of writes over the life of the drive.[54][55][56][57] SSDs based on DRAM do not have a limited number of writes.
Magnetic media do not have a limited number of writes.
Software encryption limitations
NAND flash memory cannot be overwritten, but has to be rewritten to previously erased blocks. If a software encryption program encrypts data already on the SSD, the overwritten data is still unsecured, unencrypted, and accessible (drive-based hardware encryption does not have this problem). Also data cannot be securely erased by overwriting the original file without special "Secure Erase" procedures built into the drive.[58]
HDDs can overwrite data directly on the drive in any particular sector.
Cost
As of October 2010, NAND flash SSDs cost about (US)$1.40–2.00 per GB
As of October 2010, HDDs cost about (US)$0.10/GB for 3.5 in and $0.20/GB for 2.5 in drives
Storage capacity
As of October 2010, SSDs come in different sizes up to 2TB but are typically 512GB or less[59]
As of October 2010, HDDs are typically 2-3TB or less
Read/write performance symmetry
Less expensive SSDs typically have write speeds significantly lower than their read speeds. Higher performing SSDs and those from particular manufacturers have a balanced read and write speed.[citation needed]
HDDs generally have symmetrical read and write speeds
Free block availability andTRIM
SSD write performance is significantly impacted by the availability of free, programmable blocks. Previously written data blocks that are no longer in use can be reclaimed by TRIM; however, even with TRIM, fewer free, programmable blocks translates into reduced performance.[25][60][61]
HDDs are not affected by free blocks or the operation (or lack) of the TRIM command
Power consumption
High performance flash-based SSDs generally require 1/2 to 1/3 the power of HDDs; High performance DRAM SSDs generally require as much power as HDDs and consume power when the rest of the system is shut down.[62][63]
High performance HDDs generally require between 12-18 watts; drives designed for notebook computers are typically 2 watts.

I wish I could get my head round the SSD vs HDD with a NLE rig. My builder is trying to persuade me to use a Toshiba 256Gb THNSNC256GBSJ for OS and programs, and it is only NZ$20 more expensive than the 450Gb 10k rpm VelociRaptor I was originally planing to use for the OS. That sounds suspiciously cheap to me, and I am concerned about the finite writes to SSD - mainly because I don't really understand it.
The rest of the new build is
3930K
Gigabyte X79-UD5
8 x DDR3 1600
Coolermaster with 750W PSU
Geforce GTX570
I plan to transfer the drives from my current system as a starting point, and reassess after giving it some use. That means
Either the above SSD or 450Gb 10k Raptor for OS (new drives)
300Gb 10k rpm Raptor (currently used for OS in old box)
150Gb 7k4 rpm Raptor (reserved for Photoshop Scratch in old box)
2 x 1Tb WD Blacks (data drives)
2 x 1Tb WD USB3 externals
I don't know how I would configure the drives in the new box, but have seen Harm's table and will try to follow his advice. It's a dreadful thing to admit, but I don't have a backup strategy, and the above drives are well over half full. Well over! And I am only just getting serious about video, (the rest is mainly CR2 files from my Canon 1Ds3 and 1D4)
I know it must be like banging your head against the wall, but should I avoid that SSD and go with the 450G Raptor? I have read a comment that the WD Blacks don't work well as Raid0. Is that BS or true?
I am about to give the go-ahead so need to confirm the spec.

Why do I have 200 GB of "backup" on my main hard drive? Any how can I find and erase them?

I have a MBP that was recently subjected to some liquid damage and taken in for repair. While it was being repaired, I purchased a second MBP. My newest MBP is now my personal laptop, and I'm converting the old one over to a work laptop. In that process, I've upgraded to Lion, and now I'm trying to free up as much hard drive space as possible. I have already deleted all of the music, photos and videos from the hard drive. However, when I go to see how much free space I have left, it shows that I have over 200 GB of "backups" on my main hard drive.
I have never created any backups on this drive. I only used an external HD to do Time Machine backups. How can I locate these backups and delete them in order to free up the hard drive space?

When you open FINDER, is there a folder titled 'backups? If not, have to tried 'search' or 'spotlight' to locate 'backups? By any chance is your disc partitioned?
You state that you have deleted all music, photos and videos from this drive. The graphic that you included in your query shows that these are still on the disc.
The simplest way of achieving your desired result is to open Disk Utility and erase all user data. However that does not tell us what 'backups' is. Pure speculation on my part, but if the disc is partitioned, maybe that is how it is represented on the graphic.
Click on the HDD on your desk top using Command 'I' and see if available space correlates with the the above graphic. If not this suggest a software issue.
If it does, you have to locate 'backups'. As alluded to previously, try SEARCH and SPOTLIGHT. 200GB is hard to hide. Another technique is to open finder and press COMMAND 'J'. Click on 'size' and 'calculate all sizes'. If one of those files is over 200 GB, you have located your culprit.
Better yet wait for someone who knows exactly what the problem is and will give a simple answer. I admit I'm grasping at straws here, but maybe I've at least given a bit of a starting point. Good luck.
Ciao.

How to look at movies with IPAD3 using Airport express and external disk drive (USB connexion to Airport Express)

I would like to stotre several movies on an external disk drive connected to Airport express through USB port. With my IPAD, I am able to use the WiFi network (generated by Airport) buy I don't see the disk.... how to make it happen ? Thanks. JP A

Shoudl I use ICloud instead or another way ?
I have not tried iCloud for this...and understand that it is mainly for your backups. These link might help:

Or, you could post in the iPad support area since that is really what your question is about.

Is it possible to use External HD as main boot drive? (Help!)

Hi all
I am about to buy a Seagate FreeAgent Pro (link: http://www.bhphotovideo.com/c/product/478636-REG/SeagateST305004FPA1E3_RK_FreeAgent_Pro_500GB_eSATA.html) with 500Gb and FW400/USB2.0/eSATA. I have a Mac Mini, and its internal HD is too small for me (80Gb total for about 70Gb of data).
What I'd like to do is install OS X on the External HD and use it as my main boot drive, and perhaps the Mini's internal HD for data backup. Would that be possible/legal (I only have the install discs that came with it - my first Mac :D)? If it is complicated, could you guys explain me how to do it?
I'd also like to know whether the performance would be better or worse. The Mini's got a 5400 RPM drive, and the external is 7200 RPM and would be connected through FW400 (plus a lot of free space for now).
One last question: if it is indeed possible/legal to use the External HD as my main boot drive, would it be possible to install and boot Windows on the external HD using Boot Camp or Parallels?
Cheers
Daniel
Mac Mini 1.83 GHz Core Duo 1 GB Ram 80 GB HDD Mac OS X (10.4.9)

Performance will be worse because FW400 is considerably slower than the internal bus. For startup I would continue using the internal drive. You can use the external drive for data storage as well as off-loading any music, picture, and movie files to free up space on the internal drive. You can also partition a chunk of the external drive (80 GBs) to use as a backup partition for the internal hard drive. You can clone your internal drive to the external (partition) which will give you a bootable backup. Here's how:
How to Clone Using Restore Option of Disk Utility
1. Open Disk Utility from the Utilities folder.
2. Select the backup or destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
6. Select the startup or source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
8. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Verify the settings for Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only. If they are not correct then reset them.

Disk drive no longer mounting

Hmm. Last night I took the QT upgrade and somehow during the 'optimization' process after it installed, a whole bunch of the unix files went walking - over a dozen files in the /sbin/ folder, including the mach_init (oh joys!).
Thankfully I have a second system running and I put the damaged HD into an external USB sled and copied the files back into the correct folder.
The system now boots and launches fine but I cannot get it to recognize the disk drive. The drive powers up but doesn't mount. I've run through all the system tricks to get it to do so, but it will not. I have a feeling that there may have been more files that got lost than I could get an accounting of.
Where else would I look to find and copy missing binaries for the disk drive? Not knowing this level of the code so well - I don't relish pecking and poking through everything all day - I don't really know where to hunt.
Much thanks to anyone who can get me on the right path.
Deb.

Outstanding! I'll start with those five.
The first two I've already gone through and matched up files. I was missing a 'mount_cd9660' file - found that by sorting through with a list view.
Houston, the Eagle has landed!
Now that I think of it, earlier on Sunday, I had a glitch while OnyX was running a maintenance and it locked-up. The system recovered, but I think you're right, in that the QT upgrade unmasked the problem.
Beyond that, it's been running rock-solid, and I run DiskWarrior every month or so.. but this is kind of cool, in that I'm getting to see the hierarchy of the unix system.
Thanks!
Deb.

Will OSX Lion be compatible with hybrid disk drives?

I woud like to know if the new OSX will have support for hybrid disk drives. The drives that have a medium/small SSD disk and a bigger HDD disk. From what i've hear, for now OSX snow leopard is not compatible because it start to give errors of low disk space on the SSD part, since that is the main disk and have small volume.

There is no support for hybrid drives (although, the Momentus XT is the only one I know of). The OS sees the drive as a standard hard drive. Many people are using this drive with Snow Leopard without issue. The operating system cannot see the SSD portion of the drive as such. The hardware within the drive determines what gets stored on the SSD portion. I have not heard of any low disk space errors consistent with your comment.

Dismount multiple external hard disk drives

I have multiple external hard disk drives and was wondering what the command line is that will dismount all of these at once? Note that there is also one external DVD unit as well which I would not want to dismount.
Thanks,
Lyman

diskutil unmount "/path/to/disk";diskutil unmount "/path/to/disk";diskutil unmount "/path/to/disk"
Just replace replace "/path/to/disk" with the path to the mount point, leaving the quotes.
Good luck!

Intel Xserve will NOT boot from hard disk drive

I have two Intel Xserves 2.0 QC machines
I have tried to re-install version 10.4.11 OS (don't ask) onto a Hard disk drive that is in a Disk drive caddy and inserted in the machine.
When booting from The installation DVD media
The disk is seen by the "Disk Utility" (the disk is partitioned as GUID boot) and the installation proceeds to the disk.
Once the first pass of the installation is complete and the system reboots, the system shows the folder and ? mark.
If I boot and hold "ALT" key to view all avaialble boot options the Hard Disk Drive does NOT appear as valid boot disk.
It does show, the still inserted Installation DVD.
I CAN boot from an external firewire drive and the Hard disk drive is visible to the OS once logged in.
I have tried different caddy postions (left, middle and right)
I have tried bona fide Apple supplied Disk drives
I have tried various different caddies
I have tried installing Operating System 10.5.* and 10.6.8 server
I have run SMC reset and system reset
But still I cannot boot off from any Hard Disk Drive inserted in a caddy at the front of the system.
Has anyone seen this behaviour?
Is it fixable?
Do I have replace something like the Hard Disk Drive back plane circuit board? Or even the main logic board?
I have now run out of ideas and cannot find any help in discussions or just googling.
ANY help would be very appreciated
Regards
Tony

Antonio Hi !
QC = Quad core or QX as it is written on the "pull out" serial number tab at rear of system
I have 3 late 2006 Intel xserves
On my intial posting I declared 2 were 2.0 machines - when I was trying to be concise
2 of the macines are 2.66 systems and 1 is 2.0 system - all are QX machines
the 2.0 and 1 of the 2.66 will NOT boot from the ADM and disk inside the system - whereas the other 2.66 system will.
I have many different Caddies and these have different product/model number labels
603-9965
603-9545
603-9796
these are marked "intel SATA"
The 80Gb was only one of the drives tested - I have used Seagate 400Gb 750Gb and 1Tb - all of which have been used in systems at one time or another
and as I said the drives ARE visible once the operating system (either installation DVD or external firewire are booted from) - they are just NOT visible when the system is searching for boot media.
Thanks for the guide - I will look through that and continue to try and find an answer
