T420 slots

#1 Post by karotlopj » Tue Jul 18, 2017 1:27 am

At the right hand side of my T420 I've noticed an eSATA port and two other ports but am not sure what they are for... One seems to be an SDHC slot, but have no idea what the other one is...

As for the eSATA slot, how do I attatch a disk to it and would it appear as a local disk that I can boot from? I do know that the same port can be used as a USB port.

Regarding the ports on the right side, this might help: https://support.lenovo.com/ph/en/solutions/pd025332

I've never used an eSATA port, but since it's electrically the same as an normal SATA port, I guess you just have to find the right cable (eSATA to normal SATA cable) for the hard disk you'll be using, and a separate power adapter since the eSATA port doesn't provide any power. Then go to the BIOS setup and check if it appears in the boot sequence.

Many thanks for the link.

As for the eSATA port, I was looking for a cable to provide power and wondered if there was a USB to SATA power cable, but then came across this on EBAY:

which leaves me a bit confused as to how it can work if the eSATA port does not provide power...

The eSATA port on the T420 is an eSATAp (eSATA+USB), so it does provide power. Thus, you would need an eSATAp to SATA+SATAp cable (unless you are using an eSATAp enclosure).

Would one of these suffice to connect up an external sata disk? :-

2.5" - probably, 3.5" - probably not, as I doubt the T420 provides +12V.

Just for the sake of completeness, in case anyone with T410 Thinkpad is reading this:

1. The T410 just has the eSATA port but but cannot power external HDD (unlike the T420).
(Both T410 and T420 do not have USB3 ports).

2. We have successfully used the eSATA of the T410 to connect to an eSATA/USB3 external hard drive dock, giving it very fast transfer speed even for 2.5" HDD drives!
~But it requires external power AC adapter, which is less convenient...
~The eSATA transfer speed of T410 is comparable to the USB3 port speed.

(Again, both the T410 and T420 do not have USB3 ports).

Or get a external box with ESATA using usb plug as power or an SATA to eSATA with USB as power adapter cable. I have a line on one so I can do it since I have number of computers of all types that are unpowered eSATA ports.

Someone in another Forum posting mentioned that he is using ExpressCard for USB3 connections x2.
There was apparently also another ExpressCard for eSATA connections x2 which was powered.

But obviously this is very laptop model specific equipment requirement...

A thought I had was to stick an MSATA SSD in the slot on the bottom side of the computer. It will only run at SATA II but that's still sufficient to boot off of. Since the system is running off that, you can just keep a screwdriver and a collection of old SATA 2.5" drives handy and use them as secondary since they literally just slide in and out of the machine.
