help with hard drive

can anybody tell me if there is any difference in 2.5 hd's.
i'm trying to replace a toshiba that my prostar laptop tells me it cannot read.
any clues?

 

First of all, welcome to Major Geeks.
I'm not sure what you are getting at.

2.5" drives are the same outside physical dimensions.
The main differences are whether the drive is a SATA drive or an IDE drive.
The easiest way to tell is to look at the connector.

An IDE connector has a 40 pin (actually 39) connector. 1 is missing so it can only be inserted one way. The connector is 2 rows of 20 pins (less 1) to make 39.

SATA connector is completely different, much smaller. I can't describe it to you as the laptop I am using has a SATA drive and I can't check it out while typing this reply.

Hope this helps. If not, come back, and someone expert in Hardware will assist you, I am sure. Bazza

Well for complete accuracy a 3.5" IDE HDD has 40-pins but a 2.5" laptop IDE HD actually has 44 pins. The additional 4 pins of the 2.5" drive are in fact the power connectors.

Good Luck

 

My mistake, got my 2.5" and 3.5" drives mixed up.
Sorry. Thanks for the correction. Bazza
