A really, really basic question about compatibility

Hi

I am almost certain I know this answer but:
Are all laptop hard drives compatible with all laptops?

Same as desktops harddrives are all interchangeable.

I was reasonably certain they are until I saw a web site that sells them by model.

Many Thanks

Kylua
 
Not sure, but although the sizes are probably similar, the connectors may be different.
Laptops almost never contain generic devices, which is why they can only get the upgrades the maker provides for the model.
Desktops can be pieced together with almost any combination of hardware from practically any maker - and this situation is not going to change any time soon.
That said, I know for a fact that Nvidia and ATI are both working on graphic modules for laptops that can be upgraded by the user. So maybe, just maybe, laptops will also be able to get user-defined upgrades in a near future.
But it'll be a few years yet.

1) No! physical size and compatibility with the laptop Bios; Usual limits, 2.1, 8.4, 32Gb. Also OS limits the size of disk and/or partition.

2) PATA, SATA or SCSI? Same Bios size limits as above + 128GB 48-bit LBA; ie. no, not all desktop harddrives are compatible!

Pascal, most, if not all, current laptops have 'generic' items :- hard disks, optical drives, RAM, Mini-PCI cards, LCD screens....

I have a laptop that is three years old; it is possible for me to update the graphics from a 16 Mb Radeon to a 32 Mb GeForce - not much choice but it can be upgraded. I've also replaced the 30Gb hdd with a 60Gb 7200RPM item, replaced the 'branded' CDROM with a 'generic' Combo drive; I can even upgrade the CPU.

Kylua, give us some more details on what you have and we can help you. 9.5mm high 2.5" drives will fit almost all modern laptops.

IBM IC25N040ATCS040 IBM 40GB Hard Drive 4200rpm 9.5mm EIDE 2.5in is the drive it's replacing.

So I have to look for eide, 9.5mm, 2.5 in and it'll be OK?

That makes sense, thanks.
 
If you are replacing a 40GB drive then you should have no problem except physical size...a 5,400 or 7,200rpm disk will make your laptop feel 'snappier' too!

Andy,

Your comment: "I have a laptop that is three years old; it is possible for me to update the graphics from a 16 Mb Radeon to a 32 Mb GeForce - not much choice but it can be upgraded"

I understood all laptop graphic cards were intergrated, therefore they couldn't be updated. Is that not true? I'd like to update the card on mine or at least the memory on it.

Thanks,

Keith
