Cd/dvd problem on toshiba m45-S165 laptop

Well, my hard drive died so i bought a new one and had it installed. it works fine. the problem is that i lost my recovery cd. my sister had a recovery cd for toshiba that says for m40/m45 series, so i figured i could use this. since i replaced the harddrive, i turned on my laptop and the toshiba screen pops up but when i put the recovery disk in i get a message that says "invalid system disk". i ordered a new cd/dvd internal drive (because i suspected it was broken or something) and the new cd/dvd drive gives me the same message. i went in the BIOS menu and put my cd/dvd drive to boot first, and still nothing..just the invalid system disk error. i inserted the cd on my boyfriend's toshiba and got an error message saying it was the wrong model disk, so this verifies to me that the disk is working.

SO what is wrong with my computer and why can't it boot the recovery disk and why do i keep getting the invalid system disk error? i can't get it to do anything except that message. i know the hard drive is working because before my old hard drive died, my computer wouldn't even turn on and now at least the toshiba screen pops up, but then all i get is the black system disk error screen after that. PLEASE HELP!

TOSHIBA SATELLITE M45-S165 won't charge Battery. The power connector on the back of this laptop is losse but still powers the Laptop. I bought a new battery and the Battery light does light up on the front...

it could be possible that changing the dc jack at the back may fix the problem however it could be a faulty new battery as ive had a few copies (not original) which would work for a week or so then die or others which wouldnt work at all, i finaly splashed out on a new original battery and it hasnt let me down and i bought it over a year ago.

Hope this helps

Attempt to turn on computer, no OS install windows

Marginal hard drive, hard drive cable, or hard drive controller (on motherboard).

Other suspect parts may be the CD ROM drive you're trying to run the OS install from. It may also be flaky, causing you to think you're loading the OS, but not really and not reporting errors until you discover the OS is not completely installed.

First thing to do is pull the HDD and cable out, reseat firmly and try again. May as well do the same for the CD/DVD drive.

Need a new hard drive

Hi Ekhubbar,

First of all, if your laptop is still under warranty and suffering from a hardware fault, it may be worth checking with Toshiba in the first instance so see if they can replace it. If you can provide any details about why you require a new hard drive, I may be able to assist further, otherwise if you are just looking for a replacement of the same size and spec, see below.

The product spec of your system quote that the M45-S165 comes with :

"80GB (5400 RPM) Enhanced IDE (ATA-6) hard disk drive; 8.0mm height; user removable"

Doing a quick search reveals a price at around $60.00 (for a drive made by Toshiba). However if you are going for something cheap and cheerful from egg, you may want to check out the $35 drive. It is the same size in storage, and spec wise it will access your data faster.

Here is a link to the specific product in question (on

So it would be cheap to buy a seperate laptop hard drive, but do make sure that you have a professional replace it for you.

Hope this helps,
