Slow boot of 8core Intel mac from cloned drive

Hello:
I temporarily installed a second internal drive (brand new Western Digital E7K1000 SATA 3GB Caviar Green WD10EADS 1TB HD, 32MB cache sata-300) in my 8 core Intel/Mac, 3ghz with 4 GB Ram, OSX 10.5.8 and formatted it for the Intel/Mac with 1 partition and used SuperDuper 2.5 to "copy all files" in order to make a bootable clone of the primary drive. I then removed the primary drive and replaced it with the cloned drive for test purposes.

Although the cloned drive seems to work well within the limits of the software that I tested, the initial boot time was considerably longer than noted with the primary drive. I shut the machine down and re-booted and although the boot time remained about the same as the initial test, on this occasion, a file (most likely plain text) opened on the desktop that was labeled "code."

Has anyone encountered this type of phenomena both in regards to the extended boot time and the aforementioned file and if so is there a remedy?

Thank you in advance.

The "slow startup" was likely because it needs to recreate your hot file and system caches.

The "text" file was probably because your drive wasn't named the same as the original, so the Login Items "alias" (to a deleted application) resolved to a "real" file. Just delete that entry in Login Items.

Thank you for your reply.

Is there some action that I must take to allow for the creation of the "hot file and system caches"?

No, they get created automatically over the first few startups.

Hell again:
I attempted to find the original HD entry among the Login Items for purposes of deletion as suggested but instead found an entry called "codesignature folder." The bootup folder that opens upon startup appears to be this codesignature. I tried to find an explanation for this folder via Google but to no avail. I am unable to check the box that would potentially allow for the hiding of this folder upon startup, do you have any suggestions?

Thank you in advance.

Addendum: Called Apple support and was told to delete the file rather than hide it, this eliminated the appearance of the the "_codesignature" folder. I deleted the original cache folder and repaired permissions but am still noting the slow boot...could it still be building the system cache and hot file?

Don't delete the file, just delete the entry in Login Items.

Sorry, I misstated, I did exactly as you suggested above.
Have booted up a total of six times so far and am still experiencing the slow boot as mentioned before...a difference of approximately 10-12 sec as compared to the drive from which the current startup drive was cloned. Does this suggest that the clone is an inexact copy of the original?

No, it does not: it doesn't really suggest anything other than you have different drives and they might be faster/slower/whatever compared to each other...

Oddly enough, however, the drive in question has the same spindle speed, a larger cache than the original but not sure about the seek time. It is, however, a 1 TB drive as opposed to the original which was 500 GB.

Hence the "whatever".

FYI, I have experienced this situation and I have found that it can take more than just ~ 6 reboots before the original "fast" startup is reached. I suspect it has to do in part with what is being done on the computer and how long the computer is running between those reboots. The priority of recreating the caches (which enable faster booting) might be relatively low and might have a time constant built in (I suspect that only someone at Apple really knows what those parameters are).
