Recovering data from bad partitions

I have an iMac G5. Recently I created 3 partitions on the internal hard drive; one running the latest Tiger version (my primary volume), another running the version of Tiger straight from the disk (no updates), and one running 10.3.4.
I went out of town for a week and after returning booted up. The primary volume booted (the one running the latest version of Tiger) but I got the endless spinning wheel. After a while I shut down by holding down the power button. When I rebooted, the computer could not read any of the partitions (got a gray circle with a slash through it).
Running a hardware diagnostic turned up no malfunctions.
I managed to boot using the software restore disks that came with the computer. Using Disk Utility I erased the partition housing 10.3.4 (since all of my personal data is on the primary partition) and reinstalled the software.
That volume boots fine now.
Disk Utility, however, can not repair the other two volumes (they appear grayed-out in the volumes list).
I ran Disk Warrior, but it hangs for a very long time when in step 5 (locating directories... I get a message "speed inhibited due to disk malfunction"... but it continues to churn away). Ran it for almost 24 hours before aborting.
I've also tried retriving my data using Data Rescue II (downloaded and run from my 10.3.4 volume), but it also gets hung up reading my bad volumes... maybe I would have better luck booting the app from a disk???
All I really want to do is retrieve my data, put it on an external drive, then wipe and zero out my internal drive and reinstall.
Any suggestions? Am I on the right track or totally lost? (I'm something of a back-end illiterate)

I would try to let DiskWarrior finish the rebuild process. DiskWarrior has been known to take up to several days to rebuild a volume that's severely damaged.
My G5 recently had a hard freeze and had to be force-shut-down. It would not power back on, and needed to have the power switch/power supply/logic board replaced. On a HD I pulled from it before sending it in for repair, I had 4 partitions. While they all mounted, some had errors that Disk Utility couldn't fix. DiskWarrior was able to rebuild them all, and during one of them, displayed the same "speed inhibited due to disk malfunction" warning you were receiving. I don't think that was a sign of any real hardware problems with the hard drive, just that the directory of that particular volume was severely damaged. After the rebuild of that partition (which did take several hours), there was a "Rescued Items" folder on the root level of the volume that contained salvaged items.
I think the results you'll get with DiskWarrior will probably be your best bet, but it may take a while for the rebuild to complete.
Hope this helps....

How to recover data from bad hard drive

Once a hard drive goes bad (cannot get into the computer), is there any hope of recovering any data from it? If so, how?

Do you mean the hard drive is mechanically broken for sure? It's not a data corruption issue that is causing a problem with starting up the Mac, but maybe not be a bad mechanism?
If the drive is definitely broken, there are businesses that specialize in recovering data from bad hard drives. For example
http://www.drivesaversdatarecovery.com/ (I always saw their booth at MacWorld Expos...)
The cost of such services is usually high.
cannot get into the computer
So that probably means the hard drive in question is the internal drive? If you don't know for sure that the hard drive is physically broken, you can try starting up using your Mac OS X installation disc. Insert disc in optical drive and start up with the C key held down. When you get to Installer's screen, go up to the menu bar and run Disk Utility from the Utilities menu. Does the internal drive appear in the Disk Utility sidebar?
Alternately, if you have another Mac (that has FireWire), you can try starting the Mac with the problem in FireWire Target Disk Mode,
http://support.apple.com/kb/HT1661
Connect the "target" Mac to the other Mac (running normally) using a FireWire cable. Run Disk Utility on that Mac. Does the hard drive of the Mac in FireWire Target Disk Mode appear in the sidebar?
If you can get the internal drive to appear in Disk Utility, you may be able to run Repair Disk on the First Aid tab. There are also third-party utilities, such as TechTool Pro (Micromat), Drive Genius (Prosoft), and Disk Warrior (Alsoft), that may be able to fix (or at least recover data from) the hard drive.

Need to recover data from Bootcamp partition

Hi, all,
I recently sent my Macbook Pro in for repairs after a crash (Windows partition not recognized, after working well for a year), and they replaced the logic board and HD, the former of which was dead and the latter of which "wasn't running very well". I got the HD back, and have been trying to get data off it; the problem is, most of my data was stored on my Windows bootcamp partition, which I can now see - but not access.
This is the info I got off it, since Disk Utility still recognizes it.
Mount Point : /Volumes/BOOTCAMP
Capacity : 116.7 GB (125,294,346,240 Bytes)
Format : Windows NT File System (NTFS)
Available : 26.6 GB (28,521,467,904 Bytes)
Used : 90.1 GB (96,772,874,240 Bytes)
Number of Files : 138,674
Owners Enabled : No
Number of Folders : 0
I feel as if there should be a way to recover data from the drive, since it obviously still...exists and is recognized. But using "verify" in Disk Utility returns a "verify volume failed: invalid request", and I can't otherwise see any files, since there's apparently 0 folders.
Does anyone have any recommendations for data recovery software that works in Mac? I can't just run Windows from an external drive because the HD with the Bootcamp on it is Mac-formatted.
Many thanks.

Probably the best option for attempting to recover files is attaching the hdd to a> USB Adapter and plug it into a usb port an another machine. If the hdd has not failed it should show up as a drive and can be browsed on the other machine to copy files over.

Is there any way to recover data from bad ipod hard drive?

My 60GB iPod photo shows a sad iPod icon, will not connect to iTunes and will not charge. I have recently replaced the battery and it was working for a day, but now I keep getting the sad iPod icon. If I take the hard drive out and connect it with a USB2.0 mini enclosure to my computer, can I recover the data on it?

Depends... See Corrupt iPod classic.

Can I recover data from a reformatted hard drive? I did not do a back up prior to talking to Apple Support and the guy having me delete the hard drive and start anew. My bad but is all lost??

Can I recover data from a reformatted hard drive? I did not complete a back up prior to talking to Apple Support and the guy having me delete the hard drive (10.5.8) and start anew (10.6.3). My bad but is all lost?? Years of very important information....

You will need to purchase reovery sofware such as such as FileSalvage
http://subrosasoft.com/software/filesalvage
You can download a demo copy that will tell you what it can recover
If you want to recover that you must pay for the software then
When you do the recovery, you will need another disk drive to receive the recovered files
Having install a new operating system on the disk after the retformat is going to gradually reduce the amount of data that this software will be able to recover for you

How to recover data from a hard drive with bad blocks?

An external hard drive, 4TB Iomega...connected via eSATA cable...had a power outage and the drive won't be read by OSX now. (Yes, it was on a surge protector and no I did not have a backup. I was actually preparing for the process of creating a backup when the power went out!) Anyway, I have tried using Data Rescue 3 and DiskDrill to try and recover data from the drive. I can recover the first 1/3 of the drive, but it ejects when either app tries to access the bad block. Can anyone tell me how/what software to use to recover the data? I know there are programs that will avoid the bad block but I've only found them for Windows. Are there any that will do such a thing in Lion? Any help will be appreciated...and no, I can not afford a data recovery service. Trying to do this on my own.

Basics of File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.

Is there any way to recover data from a cleared soft partition?

Is there any way to recover data from a cleared soft partition? <eom>

You could try using 'metarecover'. I don't know if that works after a metaclear, but it's the only think that I could think to try.
I think you could brute-force search for UFS filesystems within the underlying storage, but that's pretty tedious.

Recovering data from HD ????????

Hi
My HD died on my G5 a few months back
I am wondering if it would be possible to recover data from it
The situation is this
I had the idea that maybe if i start up my G5 whilst pressing T & connecting it up to my Macbook Pro via firewire 800 I might see the drives & be able to get files off there
I didnt see the drives on the desktop but if i opened Disk Uility both drives on the G5 Are there
They are both displayed as firewire drives each is named with another name underneath which is greyed out
I can click on each drive but in repair all options "Repair Permisions, Repair disc ETC are greyed out
I then tried to boot my Macbook pro with the installation disc & using disc utility from the installation CD with the same resut
Now if i can get this far I should be able to take it one step further & be able to get data from the HD or am i just grasping at straws
Any Ideas please ??

A. I would suggest never use CD or DVD.
B. Setup a disk drive just for repairs.
C. Get in the habit of using backup like SuperDuper
If you are running Leoaprd, use TimeMachine in addition to SuperDuper. SD makes an update that is bootable. And you want to insure it works.
Data Rescue II from Prosoft sounds like a good idea.
I would pick up a couple drives. A new boot drive, and one for backups, and to recover to. OWC has WD 640GB for $69.
Only use idential drives when creating a RAID, whether stripped or mirror. And yes, some tests treat the volumes rather than the physical mechanism.
SMART is not that helpful. When you tested in DW, it wrote to system log and shows how many spare blocks are left, used, which can be helpful.
TechTool Pro is 4.6.2 (5.0 is out also) and can scan a drive for weak/bad sectors.
You may need multiple backups. An original system and another of your data. When you used RAIDs you need to be doubly sure. And the best way to use maintenance utility is regularly, preventative medicine.

Recovered photos from bad driver, but files are .ithmb, & won't convert!!!

Hi, .. My hard-drive was damaged, and Time Machine backed-up everything on the external drive, except my second iPhoto Library, called iPhoto Library-2, .. and Genius Bar couldn't find the reason, nor could they fix it. For some reason Time Machine just saved thumbnails, and the dates and the locations were all intact.
However, when the technician tried to recover data from the bad drive, using Mac Drive, Media Four, via PC, all the pictures from Library-2 has .ithmb extension. Not Library one. Library one is fine just like time-machine back-up. I used File Juicer to convert .ithmb files into readable file, but it couldn't do it.
My question is, .. Has this happened to anyone? Why the rescued files are .ithmb? Did we recover the data in a wrong way? Are the picture in Library 2 corrupted, thus damaged drive, & the thumbnails? Should we use another software to recover? Is the problem using a PC to recover instead of a Mac?
Thank you in-advance for your help. Babak
P.S. Time-Machine's back-up shows Library 2 thumbnails, under 1GB, which is no way 19,000 pictures be under 1GB, but the data recovery rescue shows 14GB. .. I'm very confused what to do. Specially, that all the pictures from my iPhone was accidentally erased the next day by iTunes, even-though I stopped the sync, somehow pictures were deleted. So, my only hope is rescuing the pictures from the bad drive.

Hi, I don't know if you're still looking for an answer, but I can tell you that you can easily convert those .ithmb files to viewable .jpgs files on your working pc. It's a bit time consuming but easy. Don't waste your money on expensive software or recovery options, because they will not work. This is freeware and it's a very small command line program. You can download it for free here:
http://www.4shared.com/file/50707723/37b8a1ad/iThmbConv.html
Now follow these steps:
1. Create a new foder called Thumbs as a subdirectory of your hard drive. I assume this your C: drive. (example C:\Thumbs)
2. Copy all the .ithmb files into this folder.
3. Download the iThmbConv program file directly into this folder.
4. Now, on your pc desktop, go to Start, Run and enter cmd in the box. Hit okay.
5. When the black screen command prompt comes on, type cd.. at the end of the prompt line. Press Enter.
6. The next line should only show C:\> If not, enter cd.. again to just show C:\>
7. Now type cd Thumbs When you press enter, the next line should be C:\Thumbs>
8. Assuming one of your .ithmb picture files is named T100. (They are all T and a number, so I'm using T100 as an example) Now type iThumbConv T100.ithmb
You should now see a few copies of your original .ithmb file in the Thumbs folder in a format that is viewable on your pc such as .jpg or whatever.
Repeat step #8 for each additional .ithmb file you want to convert. Then, you can ditch the the copies you don't need.
uming, but easy.

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
Are the files lost forever or can i recover them by going to a shop or using a software?

Thank you for responding.
This might sound stupid since i'm not really knowledgeable with Macs,
but since all my files were moved from my mac computer to the external hard drive,
is it possible to recover those files through my Mac - like recovering deleted files?

Selecting data from Multiple Partitions in a single select stmt.

Hi all,
My Database is very large & my tables are partitioned.
My question is:
1) If my data is spread across multiple partitions, is there any way to select data from multiple partitions in a single query?
If we dont mention partition name also it works fine, but perofmance wise it will be very slow. (Using EXPLAIN PLAN)
(Note:I dont want to make use of Union concept, i want to do it in a single select statement)
For ex:
qry1.sql:
select empno from emp_trans partition (P012000)
This above query(qry1.sql) will work fine.
qry2.sql:
select empno from emp_trans partition (P012000,P022000)
The above query(qry2.sql) will return will return the following error:
ORA-00933: SQL command not properly ended
If anybody has any solution for this, pls mail me immediately.
Thanks in advance
bye
null

All my queries are dynamically generated. All my tables are also indexed partition wise based on date field. My question is, if i want to mention multiple partition names at the time of generating my query(select), then with parformance will be good. I have refered some books, inthat what they say is to use UNION concept, i dont want to use that, instead i want in a single select statement.
Thaks for ur reply
Bye

Recovering data from Time Capsule after conversion from Snow Leopard to Lion

Had a problem with my iMac, which was running Snow Leopard O/S. Data was backed up on Time Capsule using Time Machine, although recent back-ups had failed (but earlier back-ups had been OK). Apple support determined that I needed to re-install the O/S and they walked me through it. After blowing away all data (believing that once O/S reinstalled, could recover from Time Capsule), the reinstall failed. Took to Apple store, where they installed Lion at my request. Then tried to recover from Time Capsule, but couldn't do so. Sparse file doesn't work (it shows 10GB, which is wrong as it had several hundred GB's before due to lots of photos). Apple Support couldn't solve issue, believes it was corrupted with the last backup. Ultimately recommended that I have professional data recovery service recover data from the iMac hard-drive (as opposed to Time Capsule). Spoke to recovery service recommended by Apple, and it is very expensive (also, given the O/S reinstall, anything they recover will have new file names and no directory structure). They also said getting data off the Time Capsule is even more difficult and expensive to recover. I'm not a happy camper.
I would welcome any thoughts on what to do. FWIW, I live in South Florida and there appear to be lots of data recovery companies locally, but Apple support had said that they have only a few authorized vendors that can do it without voiding warranty, so I'm reluctant to even call them. Thanks. Steve

Your backups may be corrupted.
Try to repair them, via Disk Utility (in your Applications/Utilities folder).
Mount the sparse bundle by opening the TC in the Finder and double-clicking on the sparse bundle. Drag the sparse bundle into Disk Utility's sidebar, and do a +*Repair Disk*+ (not permissions) on it. If it finds errors it can't fix, run it again (and again), until it either fixes them all, or can't fix any more.

Recovering Data from a dead iMac G5

My iMAC G5 has had it's second logic board failure in the past 1.5 years. The repair shop says it's going to cost $550 to repair, and Apple's not going to cover a 2nd board replacement under the extension program. Given that the computer's 4 years old, and was originally only worth $1200, I think I'm going to get a new Mac.
My question is, how do I recover data from the hard drive of the old Mac? I don't want to lose all of my files from iTunes, iPhoto, etc. The Hard Drive is apparently fine, but the Mac won't boot up in its current state. Thanks in advance for your help.

Remove the hard drive and put it in an external hard drive enclosure. Then connect it to your new Mac and recover the files.

Recovering Data from a truncated table in OraXE?

A funny thing happened, i truncated a table containing BLOBs and other stuff, with over 700 entries!!, now i wanna know if it´s feasible to recover that truncated data, i'm just wondering about it, i know it sounds silly i know, but the storage space didn´t get shorter after the data was truncated from the table, so after this´s been said, can any body explain me what happened, can i retrieved this truncated data that i truncated from the table (without any previous backup)?

Truncate simply resets the pointer that marks the 'end of data' in a table to the beginning of the table. The storage is still allocated, on the assumption that you want to reuse the table and want to avoid the overhead associated with extending the table. The system knows there are never any rows past the 'end of data' and it won;t bother looking past that point.
Recovering that data from the actual current database - about as likely as recovering data from the Windows recycle bin when you've set the max allowable storage in the recycle bin to '0'. Technically possible, but needing someone with a lot of experience and patience ... and absolutely no changes to the database after truncate. An expensive proposition.
You have, of course, switched to archive log mode and been taking regular backups. (Have you not?) In which case, a 'point in time' recover, to just before the truncate, would be the solution. This brings back the database (or at least a tablespace) back to a former 'life', and is quite different from restoring a table.
