Golden Disks and IDE

The problem of recording “golden” discs has already been covered on our website (as well as in the journal CHIP, No. 8, 1999). However, the problems continue. Only, if earlier it was said that recording on “golden” disks is generally unreliable, now many people notice that recording on devices with an IDE interface is unreliable, and that recording devices with an IDE interface are generally less reliable compared to their SCSI counterparts. The EPOS Laboratory for System Studies conducted a detailed analysis of customer complaints about recording devices of this class and tried, to some extent, to simulate the conditions under which such devices are actually operated. That’s what we got.

The origins of complaints
Device reliability
Indeed, the mechanics of recording devices are less reliable than the mechanics of readers. But it is the same: for IDE devices, for SCSI. And there is no other reason to consider IDE devices less reliable than SCSI devices. So the root of complaints is clearly in this.

Recording quality
Complex issue. Our recording quality is the same for any device. However, complaints about the quality of the recording are often not unfounded. There are really at least two reasons why recording quality on IDE devices can really be unimportant.

Subjective reason
This is our desire to save: if we save, then that’s it. Having bought a cheap recorder (cheap relative to the price of the same SCSI device, of course), quite often and blanks for it are bought the cheapest. This is not a crime, but, as follows from the previous article, in this case this is the wrong approach. You need to buy such blanks on which your particular device can record with high quality.

Objective reason
This is not a complete system configuration for the CD burning process. Often this reason echoes the previous one. Many in the process of upgrading a computer from the old configuration are left “legacy” old drives. It’s a pity to throw it away, and sell it – they give a ridiculous price for them, because it is “used”. And the drive remains in the system for auxiliary purposes. What are these goals? How are he and the IDE recorder connected in the system? For the IDE, this is a matter that needs to be taken very carefully.

Let’s see what the IDE is from the point of view of the recorder.

Can I recover information myself?
Of course, in simple cases this is possible. Accidentally destroyed files are recovered by common utilities, usually without any problems. This can be done even by poorly trained users -…
