Hello Folks,

 

I have a Dell Inspiron 6400 laptop that is a 32-bit computer.  I know there is a maximum

capacity for a 32-bit computer to address Ram memory.  Is there also a maximum limit for

such a computer to read from a hard disk.  In other words, if I have stored let's say 180 GB on a

320 GB Hard Drive, I start getting messages that "There is no more space available on your HD".

What if it is an external HD?

 

Thanks

Hi,

 

Its a tricky question there are limitations on several things check this: http://www.tomshardware.co.uk/forum/291876-32-hard-disk-space-limit

 

Can you post the exact model of the processor you have and also the Operating System?

 

I don't think the error you mention have something to do with a 32 bits Operating System, it could be related with the filesystem in use or something else.

There's a limit of 2 Terabytes on disks formatted using MBR (Master Boot Record) partition styles, which are the only type that 32 bit systems can boot from.  On 32 bit Windows using NTFS, you should therefore be able to install it to a single 2 Tb partition on a 2 Tb disk.

 

Historically there were other limits such as Windows 2000 and Windows XP pre SP1 could only use partitions up to 128 Gb.

 

If using FAT 32 (which very few should be these days on a main drive, it's commonly used on USB storage however), then I believe the largest partition size is 128 Gb (with Windows 98, or 3rd party tools), modern versions of Windows will limit creation of FAT 32 partitions to 32 Gb.  It's possible to have more than one partition on a physical disk.

 

There are workarounds for these limits. For example, I have a 3 Tb external drive (Samsung D3, made by Seagate) which uses some onboard hardware to present the disk as having 4096 byte sectors instead of 512 bytes, which allows older operating systems like XP to access the full 3 Tb.

 

In other words, if I have stored let's say 180 GB on a

320 GB Hard Drive, I start getting messages that "There is no more space available on your HD".

What if it is an external HD?

 

I'm not aware of any limitations (software or hardware) which fall around the 180 Gb mark.  If that is a specific problem you're having, then please open Disk Management by running diskmgmt.msc and attach a screenshot showing how your drives are currently formatted and partitioned.

Yes.  You can use NTFS up to maybe 4TBs or better yet use exFAT because it was designed for over 2TBs.

Storage is limitless

(imagine the famous Matrix scene with the pure white background and a whole rack of hard drives that approachs you for a selection of your arsonal.)

To take the screenshot:

In XP select the Disk Management window and press Alt + PrntScrn, which saves the image to the clipboard, then open MS Paint and Paste the image into a blank canvas. Save the image.

Vista onwards - use Snipping Tool and save the file somewhere you can easily find it (e.g. "My Pictures").

 

To Upload:

It's probably easiest to upload the image file to an image hosting site such as http://tinypic.com  Uploading is self explanatory on that site. The next step is to link the image to the forum. Once the image is uploaded you should see the following screen:

Copy the content of the second yellow box down (IMG Code for Forums) and paste it into your reply.

Thank you all for your brilliant comments.

 

As a follow up on what has been happening, I started getting sporadic messages such as " no hdd to boot from"

and after turning off the computer and turning on again after a few hours, the  notebook would boot into win 7.

 

I suspected that I might be overheating the computer in the summer time without any auxiliary fan on the bottom.

So, I placed the laptop on a base about 3 inches above the table with natural ventilation, and now I have not had

any problems for 2 days now,  I will wait and see what happens.

 

Thank you all again

 

p.s. I did all available tests on the hdd and there was no bad sector anywhere.
