There are a number of variables including drive speed, number of files, file system (assuming this is ext4), etc.

The server in question receives public traffic.  Is there a way to determine the worst case scenario?

It depends on other things like the speed of your disk, CPU, and the potential amount and type of errors found/corrected.  Another variable is what type and of filesystem is on the disk and the size of that filesystem.

Either way 160GB disk is "small" and shouldn't take more than 10 minutes to FSCK and would probably only take a few minutes.  Of course as mentioned there are several variables in play so it could be faster or take longer.  If it's taking like an hour then I would be concerned.

Hi,

You might never guess the time. Since you're doing a check I assume you're expecting some trouble with the disk. If there are some then the time ill be longer depending on how many problems are located. But if you want to check a disk without a problem I'd assume it would take a few minutes.

The best way is to test it for yourself and decide.

Cheers,
K.
