st2000dm001 wrong capacity

[russell53]

I have the aforementioned drive installed in my pc. the drive is recognized in both the bios and DM. the problem is that it says it is 128GB not 2TB. it shows up in the disk mangement under admin tools but I can't exercise any option for this drive (all greyed out) Any suggestions?

Hey russel53. What OS are you using and have you checked the disk size in BIOS? You should also try the drive with a different SATA connection or a different computer to see if the same thing happens. You could also try updating the BIOS to see if it fixes the issue.

Hope that helps.

Win 7 and yesterday it was a 2tb drive. I had to clone this drive to a new drive both drives are 2 tb.

So as I see it, you could try fixing this with some partition recovery software. And there's also another option. Go to Disk Management again and click with the right mouse button on the drive you're talking about and then select "extend volume". You'll see there "Total volume size in megabytes (MB)", "Maximum available space in MB" and "Select the amount of space in MB". Take a closer look at the "Total volume size in megabytes (MB)", this should show the full capacity of the drive and the other two should show the remaining capacity, just extend the volume with the the remaining part of the drive's capacity so that it adds up to the original size of the drive and click next. This might do the trick for you. Although I'd recommend that you backup any important data which you might have, before trying out anything.

Good luck.

it say I can't do anything because of an I/O error. Switched cables and ports - no change. If the drive does go South I've already cloned it.

Well that doesn't sound good. I'd suggest that you download the manufacturer's diagnostic tool to test the drive and see if anything alarming pops out (besides the incorrect capacity).
If everything's shows up as OK, I'd recommend that you try the chkdsk command to see if it can complete the process.
CMD -> type "chkdsk /f /r x:" (without the quotations) where "x" is the letter of the drive you wish to check.

If nothing works for you and the drive is still under warranty, I'd suggest that you contact the manufacturer's customer support fur further assistance.
