Laptop CD drive intermittent reads discs


[link to this post]
 
My Laptop CD Drive is playing up. Sometimes it reads discs sometimes it doesnt. At the moment it is not reading any discs. I have tried cleaning the lens with alchohol and a qtip then it will work for a couple of discs and stop.

Cleaning the lens again doesnt help and it just wont read a disc.

There is a replacement drive on ebay for my laptop but its expensive and it looks like a pain to change.

Anyone got any ideas whats wrong with my current cd drive?

It could be a mechanical problem, e.g. the head actuator sticking or the motor not getting up to speed. It could also be the ribbon cable that connects the read/write head to the drive electronics. You could try running Microsoft Fixit and see if that detects any problems. Hardware errors ought to be recorded in the Windows syslogs, but I'm not sure where.

Should have said when I insert a disc it spins a couple of times but doesnt get up to full speed and I cant boot from it. I have tried a boot manager and it just says no media. The BIOS sees it as cdrom but it looks like its just not detecting discs.

How does the drive detect media?

And as if by magic its started working again, can read discs and boot from cds I have created. weird, wonder if it is heat related as today was pretty warm and sunshiny, now the sun has gone down its cooling off.

It sounds like either the motor is duff or it's not getting enough power. Are you running off the battery or mains?

The drive will try to read the innermost track on the CD. If it can't do that, you get "no media". TBH, I'm not sure if it's the drive that does that or the Windows drivers. The result is the same, however.

You could always use an external drive instead of replacing the built-in drive.

Its pretty clean in there as I have just been in to put a new IDE hard drive. Its running on mains but at 20v, its a universal power supply where you set the voltage as the original blew up. I could set to 22v as was the original wonder if that is the problem. Battery is toast as the machine is from 1998.

If it is temperature-related, then it's probably a faulty power regulator on the main-board, so replacing the drive will have no effect.

You could always do a network share from another machine if that's convenient.

I wonder if the new hard drive is drawing more current than the old one. The CD motor and the hard drive both run off the 12V rail. There may simply not be enough juice to power both. I wouldn't have thought that upping the PSU output would make any difference but it's worth a try.

Edit: For that matter, so does the cooling fan... and the display. If you disconnect the display, everything should be fine.

There is an atapi timeout error in the event log I will try upping the voltage to 22v.

I have decided against upping the voltage as the PSU is chucking out 22,5v the absolute maxx for the laptop accordimg to thr manual is 22.18v. The laptop can turn the display off with a fumction key so will try that next time it plays up.

I really want to put an SSD in but the Sata IDE adaptors dont seem to support 33 IDE speed just 66, 100 and 150 and its the same for IDE SSDs. When I bought an IDE SSD the bios thought I had two hard drives in instead of one hard drive and a cdrom.

Are you sure about that?

Once it bites the dust I will replace but its fast enough for browsing with K Meleon (Firefox clone) and has an unused new Hitachi 40gb drive, good enough for XP.

I hate to throw anything that still has life in it. Its a little project of mine.

Put an offer of a tenner in for a replacement CD drive for the laptop and it was accepted and on its way while the old CD drive is now working fine, typical!

Totally dead now not even turning the disc, tried turning off display and removing battery just in case they were taking too much juice but nada. Not looking forward to changing the drive as its underneath the motherboard and there is a lot of screws.

Took the hard drive out but no go, its trying to spin up twice with or without the hard disk but no go, I wonder if its a motor problem.

It probably is. Can you check the supply voltages? It might save you a lot of trouble if they're out.

Think I will just try a new drive, been looking for service manuals, and there are none for the 5033, so no idea where to test voltages, although hard drive is running fine.

This all sounds very similar to a problem I had with my Sony Vaio recently. Sometimes when I put a disc in the drive would keep spinning up and try to access it for so long until it finally gave up. I finally realised that every now and again the read head was parked right up to the extreme outside edge and having nothing to lose I gently oushed it back to the centre. Worked perfectly after that but then after a while it would happen again and once more the read head would be right out on the extreme edge. I was going to replace the drive (2 second job to take it out - just two screws and a shake) umntil I saw the price! If I need it I've got an external CD/DVD USB drive that works perfectly well.

Got the replacement cdrom today and its fitted in. XP can see it but bios cant so cant boot from it, not an entirely satisfactory outcome but it works.

Found a workaround for the non booting CD drive. A bootable floppy that has a driver to enable bootable PCMIA USB drives. I have made a bootable SP3 of Win XP on a USB drive and boy does it load the drivers quick from the USB on the laptop so I can now setup my new msata adapter and msata card.

Thats only if I cant restore the hard drive image to the msata card which I plan to do using a USB to IDE cable which arrived today, it works with an old 2.5 IDE hard drive so we will see. smile
