    It is possible, but the application has to support it. Don't try it, just do it! ;-)

    I said in my original post that I didn't hear disk head movement. I didn't say that the disk was spinning though. I don't think it's just a question of lights. jonathan15 wrote: i would try connecting one of these to the HD light connectors or swap some over to give you a better idea of where the problem is. I don't really understand how this could help me. I am not too used to hardware problems so maybe you can point out to me what you meant. Thanks for you help! Hugo Migneron

    They do not support SSE3 if that's what you are looking for. They do support SSE though. 8bc7c0ec02c0e404c0cc0680f7018827ebee

    Yes, you need an Access Point. You'll need a free socket on your hub/switch/gateway/router on the wired LAN to connect it up. For business use we normally use Symbol or Cisco gear, but that's quite pricey. Netgear, Linksys, D-Link all make cheaper ones. My home network is based around a Linksys WAG54G (version 1), which is a 4-port switch, ADSL router, and 802.11g wireless access point all-in-one. You can get both wired and wireless USB network adapters. Again, look for 802.11g for the highest standard data rates (up to 54Mbps). For the TiVo, see their list of recommended adapters[^]. You really are restricted to what they support. You might as well get two the same. It shouldn't matter if the AP is from a different manufacturer than the cards, 802.11b and g equipment is now usually compatible. When you set up your access point, you should change the administrator passwords, change the ESSID (may be called Network ID), turn on the highest compatible encryption setting (prefer WPAv2 to WPA, WPA to WEP - if the device hasn't got at least 128-bit WEP don't buy it), and turn off ESSID broadcasts. I see way too many APs that have seriously weak security or even running the default settings. If you feel really keen you could turn on MAC filtering, which restricts access to only the network adapters you specify. Stability. What an interesting concept. -- Chris Maunder

    It should still be recognized. Try replugging it into a different USB-port and into a different computer (using proper dismounting). This could be the solution to your problem. If it is not, you have probably killed the indizes or partition tables. That happens when you unplug an USB-HDD while it is writing. You may also have fried the USB-to-IDE bridge, which sits between the built-in HDD and your computer. You might want to try to use the Administration panel (right-click on the "my computer" icon) to re-partition the drive. That is the quickest solution if there is no important data to recover. If there IS important data to recover, try using a different USB-to-IDE bridge and/or plug the drive directly into a IDE-channel and try reading it from there. If its recognized, but not accessible, a disaster-recovery tool might help. AFAIR, SpinRite (www.grc.com) can recover destroyed indizes and tables.

    Thanks to you, I've now found a way to use the PORT.dll with WinXP as well, and it's nearly the same as with win89: You just have to set the outports to 0 at the beginning.

    The ME-50 has an unbalanced preamp out so, yes, you could use it as a Mic preamp. The better the soundcard, the better the sound. Depending on what type of recording you're looking after, you might want to get a better audio card. Check out www.echoaudio.com[^].

    Hi everybody. Thanks for all your suggestions. I've checked each and every answer and the problem is solved. The HDD had a pretty confusing documentation of how the jumper must be set. Accidentally I set the jumper to limit the disks capacity to 32 gigs. I probably would have found out sooner, but when I placed the same disk (with the same jumper setting) into the master position, the jumpersetting did not cause the limitation. Bios showed an 80 gigs hdd which is perfectly right. only when put into a slave position, the jumper affected the hdd's max capacity. Don't know why that is. At least I've set up the box by now (I'm already posting this message from it :-D I'd like to thank you all for your input. Without it, I'd probably would have gone mad...
