meters/counter hesitation

[Bluesdude]

In play and record my meters and my counter have started to hesitate every 2 secs or so simultaneously.They almost freeze then go, freeze, go etc etc as if there is a clock problem. The audio playback seems okay as if it recorded alright but I am reluctant to carry on tracking in case this leads to a worse problem and I lose it all. I called Tech support and paid the bucks but they recommended looking at my drives so I ran some utilities on them etc to no avail. I tried recording to my system drive same deal. I have tried all the usual stuff I know about. Trashed prefs,checked buffer sizes,DAE and LE memory allocation, removed all non needed extensions in Ext. manager, 256 colors, fonts, deselect smooth fonts etc etc etc energy saver off. Anyone have an idea. It will be much appreciated, this is holding me up big time.
Digi 001,B&W 400 G3, LE 5.1.1, 512 ram, IBM Deskstar 60 drives, dedicated audio drive..8 partitions, about 7 gig ea. There is no removable media connected like scanners or card readers. I recently installed a Macally powered USB hub and a PNC compact flash card reader and Kodak picture software but I have turned this all off in Ext Manager. Thanks.

how many tracks and plugs are you using when this happens. my meters tend to jump instead of flow smoothly when i'm almost maxed out...

[Bluesdude]

None. Just starting a session so beginning with drums... 2 Mono tracks for Kk and Sn, 1 stereo track for kit/cmbals.Actually transferring some live drums recorded on a 16 track Fostex to the 001. No plug in's yet, nothing. Thanks for the fast reply.

Hey Blues.

Funny, I noticed the same thing today. I normally dont see this kind of thing until I have a lot more going on, but today it was with the first few tracks as well. Actually it was more in Rec. mode. Playback was less noticeable. Good news is, I finished most of the session today w/o any problems. Dont have a clue though, sorry.
