Replacing HDD of IBM ThinkPad R31

[Guest]

Archived from groups: comp.sys.ibm.pc.hardware.storage (More info?)

Hello everyone,

I have an IBM ThinkPad R31 (Celeron 1.06GHz version), and recently its
harddisk died. I will replace it, but need some advice:

The original disk of the laptop is an IBM TravelStar 20GB / 4200RPM. I
will probably replace it with a 40GB Seagate, which is easier to find
here.
There are two options:
1. ST-94019A, 40GB, 4200 RPM, 2.5"
2. ST-94011A, 40GB, 5400 RPM, 2.5"

The higher RPM suggests that I should prefer the 94011A, but would the
laptop have problems powering / accessing a disk with faster RPM than
its original disk ?

Also, are there any limitations in the BIOS etc that will cause
problems with the 40GB size, which is double the size of the original ?

And lastly, should I expect any form-factor or IDE connector problems
in fitting the Seagate drive ?

Many thanks in advance,
-arifi

Hi and thanks, but I could not figure out what you really mean by
>> Shouldnt do.
Do you mean that I should not install something with different specs
than the original,
or
that it should not cause any problems ?

And a last minute question: is a 5400 RPM drive likely to cause heating
problems ?

Best,
-arifi

Thanks for the info, everyone! I am ordering the 5400 RPM Seagate since
its power requirements are the same with the 4200 RPM version. However
Seagate's power requirements are quite higher than the Hitachi ones -
is this a measuring difference or does Hitachi have the lead in
technology here ?

Cheers,
arifi

Powering should be unproblematic. Heat could be an issue. Have a look
into the manual of the original disk what its power ratings are. Then
have a look into the manual for your prospective replacement and compare.
(I found that Fujitsu's Laptop disks need less power than Seagate).
If more than 30% or so increase you may have problems. It is really not
easy to tell. However IBM laptops are fairly well designed and I would
not expect heat problems.

Could be. Was the laptop ever available with a 40GB disk? There
should be no limits besides the BIOS.

If this thing has the same drive bay as the X31, no. Unless you
try to replace a 9.5mm high disk with a 12.5mm high one. These are
the two heights for 2.5" disks. You can remove the drive bay
(usually just one screw, the manual should explain it) and have
a look. You find the external measures of the seagate disk again in
the disk manual.

Disk manuals are available from the vendor websites. For IBM
it is now Hitachi.

I replaced the IBM disk in my X31 with a Fujitzu 5400 one, no problems
at all.

Shouldnt do.

Dunno, but thats not that likely with that vintage of ThinkPad.

Just check the thickness of the drives and compare that with the old one.

As long as it's a 9.5mm height drive, no problem. We use only IBM thinkpads
at work, have some familiarity with them.
I'm running a 7200rpm 40GB HGST drive in place of the 20GB that came with my
T23 [which is older than the T31].

It should not cause any problems.

It might if the design of the laptop is marginal. You dont
say what the original drive was tho, it may well dissipate
as much power as the new ST-94011A and in that case
should not cause heating problems.

Nope.

Yep, Seagate has a real tendency to ignore the power
requirements compared with some other manufacturers.

The Seagates also take more power than Fujitsu, so I think
the Seagates are just power-hogs. May be a problem.
