I have two laptops, a Dell XPS running 64-bit and HP Pavilion 32-bit and I want to replace the Dell hard drive with the hard drive in the HP temporarily because my Dell laptop became very slow and I want to test if the problem is with the hard drive or something else. The question is: Can I do that without losing data in the two hard drives? I know that maybe data on C partitions will be deleted and that's OK, but will the rest of the data will be lost or not?

  • It depends on your plan of the entire action. What exactly are you going to do? – gronostaj Nov 18 '13 at 21:19
  • Thank you for your reply, I'm just gonna take the hp hard disk and put in the dell to see if the dell laptop works fine with this hard disk or not. If it worked fine then the problem will be in the dell hard disk causing it slower and lags and I will replace it with a new one. @gronostaj – Mina Hafzalla Nov 18 '13 at 21:23
  • It won't boot. Windows installations are configured for the hardware they are installed on. You can try plugging it as a secondary drive instead of optical drive, but this way you won't be able to test it reliably. – gronostaj Nov 18 '13 at 21:24
  • Unless you plan to reinstall the OS, data should be safe. However, I am skeptical about OS itself. If its OEM copy, it may not work on laptop of other brand.. – tumchaaditya Nov 18 '13 at 21:24

    Backup... backup fast.... it might be ok but damaged sectors ussually mean a failing hd. If they get worse get a new one. – Rik Nov 18 '13 at 21:47

Why don't you plug the disk to the other laptop externally and try to copy files to and from it. To see the speed of copy operation. This will not harm your disks.

  • Thank you for your advice. Actually while copying files to USB flash drive the laptop becomes more slower and I can barely use it for listening music, watching video, browsing etc.. It delays responding in anything and freezes for a couple of seconds. I got copy transfer speed 17.5 Mbps to 21.5 Mbps using USB 3.0 port to transfer 5.43 GB of 36 video files – Mina Hafzalla Nov 18 '13 at 21:42

There's a far easier way to get better information about the health of your hard drive.

Download HD tune, check the SMART status, run speed tests and post here if you don't understand the results. www.hdtune.com

  • Thank you for your reply, This is what I actually have done. I tested the HDD with HD tune pro and it came up with 31 damaged sectors, 104402084 interface CRC error count and 18.9 ms access read time which is yellow highlighted by the software so it probably maybe abnormal. Does this indicates a hard disk failure? – Mina Hafzalla Nov 18 '13 at 21:59
  • Reallocated sector count? 31 bad sectors isn't a great start. You've got backups of anything important right? – Chris Nov 18 '13 at 22:12
  • Yes, I'm doing backups for my valuable data now. What about the Interface CRC error count? Thank you again. – Mina Hafzalla Nov 18 '13 at 22:15
  • Interface crc concerns the SATA interface. While the number is high, it's the bad/reallocated sector counts that you should be most concerned with. Tbh My guess is yes, you need a new drive. – Chris Nov 18 '13 at 22:25
  • Thank you for your reply, I decided to buy a new hard drive hope to solve the problem. If you have any other suggestions please let me know. Thank you very much. – Mina Hafzalla Nov 18 '13 at 22:29

Problem Solved . It was the hard drive, it has delay. Dell diagnostics didn't show the hard drive delay. A technician have made a delay test with a software and it came up with a delay error in the hard drive. Software called HDD Regenerator.

I replaced it with a new one and the problem totally solved. No lags or freezing anymore. I just wanted to share my experience if anyone have this problem, this post may help.

Regards.
