[T400] DVD-RAM extremely slow

2008-10-03, 6:30 AM

Hi,

 

I just bought a T400 and I'm disapointed because the DVD drive seems to be really slow. I takes about 8 mins to copy 700MB from a CD to the hard drive. With my other laptop it takes about 4 mins.

 

When I booted up the laptop for the first time, I burned the recovery DVDs, and then I tried the rescue & recovery thing. It took me 10 minutes to boot on the recovery DVD. I started the recovery process at 23:00 and when I woke up at 4:00 in the morning the process was at 15%.

 

I tried to mount the recovery DVDs on an other machine and what I saw is a lot of errors (bad sectors).

 

The DVD-RAM is a UJ862A.

 

Is there something to do to fix that ? Is the DVD drive broken ?

Hello,

 

the recovery dvd´s had to be burned onto cd-r/+r or dvd-r/+r.

To burn it on dvd-ram will lead to your experience and faulty disks.

If you are in warranty, you can get your R&R disks free from Lenovo. Please call support, they will help you.

 

 

Kind regards

Andreas

Hi Andreas, thanks for your reply.

 

I never said that I burned the recovery DVDs on a DVD RAM. When I say DVD-RAM I speak about the device. The recovery mediums are DVD+R.

 

The recovery DVDs are not really the point here, the problem is that the drive is really slow and the DVDs I burn aren't readable. Is there a way to check if it's a hardware issue ? Are there some Firmware updates available ?

Hello,

 

you can try a Linux Live Cd and burn from there.

If it will be sucessfull, the your drive seems ok,

otherwise contact support, they´ll send a new one.

Or try another dvd or cd brand, some drives are very picky, with some brands.

 

regards

Andreas

Hi,

 

do you know a Linux LiveCD I can load to RAM ? Because if I want to burn something and do speed tests I'll have to eject the liveCD. THe Ubuntu LiveCD I have doesn't have this option (or I didn't see it).

 

If the drive is broken, will I have to return the laptop or only the drive ?

Please try a Knoppix Live Cd.

 

Or simply use PC Doctor.

Please check if DLA mode of the drive is off.

Andreas

Thanks for your help Andreas,

 

it seems to work better with Knoppix. I also found out that the drive doesn't like the Philips DVDs, when I burn DVDs at full speed, they are not readable. I don't know if that's normal because I can burn these DVDs at full speed without problems on my other machines.

 

What is DLA and how to check if it's enabled ?

 

Thanks in advance

Hello,

 

yes, then try just another brand.

 

DLA = Drive Letter Access, see here.

Disable DLA from autostart. It´s a part from Multimedia Center.

TuneUp Utillities is a confortable way to disable, not delete, the entry.

 

But, when your Thinkpad is working now, then there no problems with DLA.

 

Regards

Andreas
