Title: Scanning of CD drives
Post by: BlitzenZeus on June 22, 2004, 08:12:08 AM
When I was browsing some CDs to copy a few files it took forever as Avast was polling the drive to scan some files, and even causing explorer to hang as the hardware was not responding in time with the information.  So for now I've added my cd-rom drives to the exclusion list, and this has not been an issue anymore.

There has to be a better, and safer way to do this.  While you can't clean optical media, I would still like it to scan them, but in a lesser/quicker mode if even possible.  Am I missing some obvious setting in the resident scanner?

XP Pro SP2 RC2(Clean install #2149, non-public build)
Duron 1.2ghz, 100mhz FSB, 512mb Ram
48x CD-RW
(Yes, I know I need to upgrade one of these days)
The HD, and CD drive are on different IDE channels so that is not an issue.

Thank you for your time 8)

What are your settings of the Standard Shield resident provider?

Custom - Based off of the high setting

It not scanning every file, but its scanning files with selected extensions.  I'm not noticing much of any slowdown from my hd from the scanning.  Basically all the options are enabled, except for scanning every file.

I think the slow down of CD could be related to the specific files (extensions) that you have there and not too many in the HDD.
Other strong reason: CD read access is extremelly slower compared to HDD.

Well those were things which I considered when I put them in the exemptions list.  Currently if I feel like it, I will manually scan the CD, but this level of scanning has little to no impact on my HD at all so its staying there.

I cannot scan blank CD's.  In fact, it doesn't even detect that there is a CD in the drive.  I even switched CD's and it still does not detect the presence of a disk.  Where is the problem?

BlitzenZeus,
speed also depends on what cable(s) you have the drive and de cdrom. On seperate cables is a little faster.
It also depends on the mode that the drives run in and what kind of connection the drives have (eg ide, scsi etc)

harlemnocturn,
there is no problem. A blank cd doesn't have any info on it. Not even a 'mbr'. So there is nothing to scan. In fact there is not even info on possible files to scan.

Thanks for the reply; however, as someone who completed A+ training, one does have to scan blank media for viruses.  After all, they are made by people.

But it's blank ................ nothing on it! 

No file system ............. nothing to read ............ not formatted  ........... nothing there!

I think the intonation is that 'people' are not nice and cannot be relied upon (sad but true) a 'doctored' CD in a new pack perhaps!

Blank cd's are just that .......... empty

Then it will have a file system and be readable. 

Exactly and a possible 'bug'

By all means, but what troubles you so much.

As you know I cannot (or rather did not quote anything you did not say. It is just the time lag between my picking up your message and you editing.

If you prefer I will delet my entries.

Not at all, don't delete anything, report to the mods I'll go by their decision

You have me replyimg 03.31.19 "then it will have a file system and be readable"  in your quote My reply was at 03:27:19  "blank cd's are just that"

Tell me something... did you original post (timed at 2.27.19) not say EXACTLY what was quoted??? You edited at 2.30.36 so the quote is accurate.

If you object to the time lag (43 seconds I think) then take it up with the admin or smf.

I can't be responsible for you editing your post whilst I am already answering it... can I???

As I said I'm happy, more than happy, to delete whatever you want to make you happy.

A blank cd is not like a 'blank' floppy. A floppy normally is already formatted and has a mbr. A blank cd has nothing on it. So you can 'scan' a blank floppy but not a blank cd.

You can also 'scan' a formatted (but empty) cdr, dvdr, memstick etc. It wil just say that there are no files to scan.

But you can't scan a blank cd or dvd. Anything that hasn't already have a 'format' can't be scanned.

Eddy,

Of course. I 'think' Harlemnocturn (read his post) was referring to something else ie malicious/accidental interaction by humans. But he'd have to clarify his meaning.
