Approx 25% of HDD capacity missing? (370GB from 500GB drive)

Post by GaryL »

Hiya

Just a quick question. I’m new to Bubba btw. I’ve done a clean fresh install with a new 500gig hard drive. Yet total disk size is only 379246mb, which works out as 370.36gb.
Now I was expecting to lose a few gig as you do with hard drives, but losing 130gig is a bit much I felt. Is this right? Or is there something up?

HDD is a Western Digital 500GB, possibly a WD5000AAJB but could easily check if need be, just can’t remember off hand.

Regards
Gary

I have exactly the same problem. I have a WD 500g drive that I installed myself yesterday. I got exactly the same available space. The drive is:

WD5000AAKB
Caviar SE16 500gb U133 16M

On second look my drive is the same model as yours:

Western Digital WD5000AAKB 500GB Hard Drive 7200rpm 16MB Cache OEM

Which I bought from Ebuyer.com.

Hi,

This sounds strange. The only thing i can think of is that these disks report their size in a non expected way. Could one of you please get the contents of the /proc/partitions, which is used by the installer to calculate the disk size, of one of these units.


A simple

Code: Select all

cat /proc/partitions
when logged in on a terminal should give you that info. Further more a

Code: Select all

df -h
could also be interesting.

Also, I removed the HDD from Bubba and fitted it to a usb caddy and plugged it into my Win XP machine, heres the results:

Just a little update.

I removed the HDD from Bubba and repartitioned & reformatted it in Windows XP (NTFS file system).

The end result was 465GB, which is identical to my 500GB SATA drive in my Windows Media Center PC.

I then refitted the HDD to my Bubba and reinstalled the OS, but it still was picked up as 379 246 MB (370GB).

:( :(

Lots of good information, Gary. I hope this is software issue rather than the discs themselves - sending things back is a pain.

Any thoughts Tor?

Well I hope its enough, cause to be quite honest I know bugger about Linux. I was just google’ing commands and giving them ago.

Its defo not a hard drive fault as it was recognized on my windows PC as 465gb.
And its not a Bubba hardware limitation as I believe Excito use Seagate 500gb drives without problem
But there could possibly be a compatibility issue with this particular model I guess, who knows?

Might see if I can use Partition Magic to expand the 376.26gb partition into the unallocated 88gb space. That would leave me with the correct 464.26gb of storage space if it worked.
But to be quite honest I still don’t think I would be happy with this even if it did work. I would rather the Bubba install process partitioned the drive correctly in the first place.

Hi,

This was a tough one.

Unforetunately it seems like Linux does not think this disk is a 500GB. /proc/partitions says that the disk contains 396111896 sectors of 1K each giving us 405GB or 377GB depending on how you interpret a MB. This is also verified by the hdparm output that GaryL provided.

Why this gets reported wrong a mystery to me. Could one of you also provide the output of dmesg so we could see how the bootlog presents the disk?

Will give dmesg a go. Just need to reinstall the Bubba OS again.

Partition Magic was unable to extend the partition. But I got hold of SystemRescueCd http://www.sysresccd.org/ and I was able to extend the Ext3 partition with it. But no matter what I tried I could not get Bubba to boot. Just kept getting the flashing LED no matter low many times i rebooted it or how long i left it.

Do you reckon there is a software fix for this??
Or is this a Hardware compatibility issue??

Also just for my own reference, what are the makes/models of the hard drives that you use for the following;
Bubba 80GB
Bubba 320GB
Bubba 500GB
Bubba 750GB
