My new Precision 3520 mobile workstation is down after only 3 days of use, OS won't start normally. I decided to return it anyway.
So I need to back up hard drive data first. But new problems prevented me from doing it...
Info on my Precision 3520:
OS: Ubuntu 16.04
HDD: Seagate ST500LM021, 500GB 7200RPM
What I did:
Take out the Precision 3520 hard drive, and connect it as a USB device to my old Inspiron N5050 laptop (runs windows 7).
The connection is done via an Insignia SATA-to-USB 3.0 converter, it worked fine with other HDD of comparable model (a Seagate Momentus 5400.6, 500GB 5400RPM).
Upon connection, the driver is successfully installed, but the HDD shows up as having only 2GB size, with only OS files inside.
The rest 400+GB of disk, with user data, can't be found.
How to solve this?
Just in case if you need this -- the Precision 3520 can't enter OS desktop.
After displaying the Ubuntu start up logo, it got stuck there with black screen, keyboard not responsive, but the following error message pops on and off once every 2-3 seconds:
[***:*****] pcieport 0000:00:1c.0: PCIe bus error: severity=corrected, type=data link layer, id=00e0(transmitter ID)
[***:*****] pcieport 0000:00:1c.0: device [8086:a111] error status/mask=00001000/00002000
[***:*****] pcieport 0000:00:1c.0:  Replay timer timeout
(Note: those *** are some random numbers)
Running the pre-boot hardware diagnosis shows all devices are normal.
And it can still enter BIOS setting.
After clearing "power event log" in BIOS setting, the error message above disappeared, but the same problem persists.
(Now I'm not concerned about this OS start up problem, because I'll return it anyway. What I want to solve is the HDD data backup issue!)
I appreciate anyone who can help me on it!
Instead of removing the hard drive I would have used another PC to create a bootable DVD of some flavor of Linux.
Anyway, I wonder if it is something to the partitioning of the hard drive.
Windows doesn't natively support the ext3 and ext4 file systems that are commonly used in Linux, so if your Data partition(s) use those file systems, you'd need to get some sort of utility that allows Windows to interpret them. Or you might just want to capture an image of your entire drive. I've recommended Macrium Reflect Free on here several times. It only runs in Windows (and its Window PE-based bootable media), but it can capture images of Linux partitions just fine.
