I have a 1 TB Seagate drive in my Lenovo desktop which has three partitions and I got an error “hal.dll” missing or corrupt” after rebooting and I found that the system is not recognizing the this drive. I did not see this drive either from BIOS or from Devise Manager, I put it in WD external drive enclosure and connected to two other systems running windows 7 using USB and got an error "you must initialize a disk before logical disk manager can access it" when checked from "Disk management". I still see the "disk was ready to use" message when connected to my laptop running Win7.
I can't initialize the disk as I have lot of personal files/pictures on this disk that I cannot effort to lose. I also tried with Ubuntu and this disk has not been identified. Any help and I can see the disk was spinning and a green light was blinking when connected. Seagate tools did not help.
I have no issues with the system. I was able to install the Win 7 on another 500 GB disk that I have with me. Any help appreciated.

Download HDDrive Scan and run the verify test on you 1TB Seagate drive. If you see a lot of red you know its a bad hard drive. To get your data back download Recuva and see if it can pickup your Seagate drive to recover whatever data is on it. Make sure you enable deep scan, it will take awhile to complete.

Hi, Thanks for your reply. Recuva did not recognize this drive. Could you please let me know which HDD scan to be used. Also, will it further damage the data on the disk. I was under the impression that this was an issue with MBR, so far

No hard drive scan will not damage your data. All you need to do is run the verify test that it has. If it was a MBR issue usually Windows will say "Missing MBR" when you try to boot from a hard drive. However, this is not the case as it could be a failed hard drive since Ubuntu and Recuva cannot recognize it. Disk Manager too likes to throw weird errors when a hard drive is failing or failed. How long have you had your hard drive?

Edit: On HardDrive Scan you can also do a smart test that will confirm a failing hard drive. I would do that before you do the verify test.

I was using this HDD for the past 4 years and unfortunately never thought about backing up my data. I will try to run the scan and will update you at the earliest. Thanks again.

Hi thatmoney, I downloaded the software and tried to to run the scan in verify mode (Newtaks=>Surface Tests=> Verify+>Add test)) and it just took only one second and I got the following message.
Also "SMART" button was disabled when I selected this drive from the drop down list.

Executing
Bad block found, start LBA : 0

Status of the test was finished.

Please let me know how you want me to proceed now.

regards.

Alright, I never seen a error like that before. Have you tried using Seagate's hard drive tester? You might have better luck with that one.

Yes, I tried that Seagate DiskDrive wizard and it says that it did not find any Seagate drive installed on this system. Shall I go ahead and burn a bootable CD and try once again, if that helps. Thanks for looking at this.

Yeah give it try. If that doesn't work then your hard drive has probably failed. If the data is really important there are companies how specialize in data retrieval from dead hard drives.
