WD120 showing up as 110GB?

[bob4432]

i understand how the rated size and actual of hdds works, but i would have expected that a 120GB hdd would be ~117, not 110. is this correct?

 

[minendo]

It is right.

 

[VisableAssassin]

My seagate 160's show up at like 147gb or some junk
so you should be roughly correct

 

[XBoxLPU]

160gb = ~152gb
120gb = ~114gb

WD secretly hacked into your comp last nite and took the other 10gb.

sm@rt@$$....i was just curious, my 60GB=57GB, 36GB=34, i just thought it was a little off

thanks for the replies

Read the anandtech Faqs

Why doesn?t my hard drive have the advertised amount of space?

 

[charlie21]

You have to take filesystem overhead into account as well.

 

[johnnnny5]

I have the same (likely) drive and I get 114gb.

However beware that if you are using FreeBSD, I have run into problems with WD drives and size detection. Not 110gb though... I once had it read as less than half the actual capacity.

Right-click the drive in Explorer, and select Properties. If the total space is a little over 120,000,000,000 bytes, it's fine.

 

[bob4432]

it says capacity 120,031,477,760 bytes with 71,946,240 bytes used = 119,949,531,520 bytes free.

how does 119,949,531,520bytes=111GB?

 

[dennisjai215]

because 1,000,000,000 does not = 1GB

My 160gb

163,921,571,840 bytes...... = 152gb

Read the AT FAQ!! ( as posted above )

Another answer. Also has a very helpful chart.

That's normal then - you actually got a bonus. (Everyone does these days though.) WD promised you at least 120,000,000,000 bytes of storage space. You got 31,477,760 bytes more than you thought you paid for. So stop complaining.
For the record, my 200GB Maxtor lists its capacity as 203,921,108,992 bytes. Yay, ~3GB bonus.
Windows says it's 189GB.
Gigibytes vs Gigabytes.

 

[jagec]

In my experience Maxtors usually give you a bit more free space than WD. IE, my 160GB Maxtor reads as ~152.5GB, my friend's WD reads as 148. I've collaborated this with a couple other drives and it seems to be true.

 

[McMadman]

Technically my wd 250gb drive is 232gb or 249,995,558,912 bytes

I've been cheated out of 4,441,088 bytes!

Actually this is the only drive I've ever owned that didn't meet or exceed their specified number

correction!
60gb=55.8gb
36gb=33.48gb
just a little off?! dude the formula is .93 x whatever the capacity of your hd is..

160gb= 148.8gb to be precisely, just ask einstein!

that is overrated :\
164gb=152gb
123gb=114gb
^always remember that you're actually getting more then you're pay for if you see this much capacity!

I wonder if yours had a lot of bad areas, which were marked off at the factory?
You could check out the SMART data using Everest. Under the Storage section, click on SMART. I believe that the ones to look for are Reallocated Sector/Event Count - check for what the Data column number is. Also look at the read/write error rates, which hopefully are 0. And of course, if anything's failing, then there's a problem.

There probably isn't any problem though - all drives have defects at manufacture. They're just safely marked as bad at the factory, and your drive acts like they're not there at all. I guess sometimes it just gets a little bit below the rated capacity. Of course, your drive is off by about 0.0017764352%. I guess that qualifies as "OK" with the QC folk.

I was actually joking, I'm not exactly concerned about it being off - There could have been some minor space loss in the partitioning/formatting, and it is CLOSE enough to specified size, I can't complain, as long as it can cope with high operating temps (at least 46c if not higher.)

I did run that program anyways (looks an awful lot like aida32, and it only detects drives on the controller card just like aida did too)

If anything was marked as bad, it was done low level, the drive is only about a month old (maybe 2 weeks usage)

(smart data below - if quoting trim this up)

ID Attribute Description Threshold Value Worst Data Status
01 Raw Read Error Rate 51 200 200 0 OK: Value is normal
03 Spin Up Time 21 114 114 4833 OK: Value is normal
04 Start/Stop Count 40 100 100 9 OK: Value is normal

C7 Ultra ATA CRC Error Rate 0 200 253 0 OK: Always passing
C8 Write Error Rate 51 200 155 0 OK: Value is normal


EDIT: I'll actually add in something relevant to this thread
My WD1200JB is partitioned into 2 drives, 55.8GB+55.8GB for a total of 111.6GB, those sizes are of course what windows says in properties.

nice chart

 

[Brody8877]

I have Western Digital Hard. It came with my computer and it show up as 110GB instead of 120GB too. Also I have on for my server and is the same thing too. So your not the only one. That pretty much applies to All WD IDE 120GB 7200RPM with 8mb cache.

 

[yourdeardaniel]

my wd 200 shows up as 186 and ibm 120 shows up as 115
