Yes, I used LinuxPPC 2000 Q1. I've used it for making compressed backups and more recently for modifying boot blocks using ghex. For awhile I was pulling boot blocks from the drive, copying them to an HFS volume, and editing them with HexEdit before I found ghex. (I have yet to encounter a unit that accepted the factory password, so editing has been necessary to enable shell access and set the password.) All my blessings were using MacTiVo Blesser (its icon is my design donated freely ), and all my CD-R backups were burned using Toast (I have 1.2.1 and 1.3.0 14hr backups and 1.3.0 30hr backups, the latter actually being smaller).
I have been trying to get the LinuxPPC 2000 Q4 CD to boot on my beige G3, no joy. I started by downloading the image and burning it to CD-R with Toast. It wouldn't boot when selected as the startup disk or using the C key at startup. I thought maybe I had a bad CD so I ordered the set from LinuxPPC.com. These arrived yesterday along with the FWB Disk Tools PE CD. The Disk Tools CD boots just fine. Still no luck with the LinuxPPC CD. On the comp.os.linux.ppc there seem to be quite a few installation problems with this release. So now I'm working my way through alternative installation methods.
I bought FWB Disk Tools as soon as I read Alexander's post about using it for backup. After reading the TiVo Hack FAQ I sure wasn't going to do anything without a backup. Since I did a device copy of my HDR31202's Quantum I don't know how big a compressed copy will be but I'm keeping my fingers crossed that it will be small and have the "factory" password. I also have a second TiVo, a HDR112, that I got as a refurb, that is going to be my hacking machine. It has the dealer demo so it will probably be a large backup. I plan to install another image from my original 30 hr A drive in the HDR112 on an 40 GB LCT20.
However, for things like running Maxtor utilities and unlocking Quantum drives, a PC is still necessary. The needed apps for these steps haven't been ported to the Macintosh. I had to use a PC at work during long winter hours to run the utilities. (Thankfully the first 30hr unit I got my hands on--my mother's--did not have a locked drive.)
I've been lucky and haven't had any locked drives to deal with. I did my upgrade using 2 - Quantum LCT20s. After reading all of the issues that were being reported about Maxtors I decided to err on the side of fewer hours. Now that my Quantums are nearly full I have seen some stuttering.
I have a theory: stuttering arises from a combination of limited disk space and fragmentation. I think the software needs two things to keep stuttering to a minimum: space and time. The space is required to keep the data in contiguous blocks. The time is to defragment the drive. I notice that the drive is very busy almost all of the time. I only record about 5 hours/day. I've only had time to watch about 2 hours/day. The drives are real close to being full. Most of the recordings are marked to save until I delete. TiVo suggestion recording is turned off.
All my efforts have involved using software I either already possessed or could be freely and legally acquired. (Toast came with my CD-RW drive.)
Toast came with my CDR drive also but I haven't gotten to the point with LinuxPPC where I can mount my TiVo drive.
Now I have a new PC invading my home. I'm assembling a system myself. Unfortunately my first attempt resulted in an overheated CPU (AMD Thunderbird 1.1 GHz). "Smoked" is the technical term for its state, and I won't get a replacement until Wednesday. Without the sound card I have yet to purchase, that system cost me $800.
Well as mentioned in my previous post I just purchased a pile of PCs. I'm sorting my way through finding out just what I have. The piece that excites me most is a full ATX tower that has 4 - 5.25" bays and 7 - 3.5" bays. It currently has a P-120 CPU but I envision something a bit more energetic (dual P3 866s or P3 966s). I intend to keep three of the boxes, one as a Linux workstation, one as a Linux server and one as a Windows Professional workstation. I may make the first one a dual boot with Windows 98SE if I can't get a CD-RW working with Linux. I plan to put two removable HD racks in the Linux workstation to simplify swapping TiVo drives in and out.
I'm about ready to add a 60 GB to my second TiVo and restore my original 14hr drives to virgin 1.2.1 and 1.3.0 condition. I've been holding off as I've been waiting for the 2.0 release and Tiger releasing his new hack to utilize all of two drives so I could have two units with a 60-60 and a 45-45, but I guess I can settle for two 45-60 units. That, and I've wanted to see if I could install a DVD-ROM into the second unit instead and port LiViD to the TiVo.
Yes it will be time for me to do the revert to virgin step soon also. I have a spare 40 GB LCT 20 that I am going to image with the virgin HDR31202 A drive. When the word comes from Otto I'll do the swap.
I'd like to take Tracer's trick of bank switching pairs of drives one step further by adding a menu option to the TiVo that allows on screen selection of an alternative bank with a reboot to select it. I'm a long way from there though.
Unfortunately, between work and watching TiVo, I don't have much time left to hack anymore. Maybe when I switch to working four 10hr shifts instead of the five 8hr shifts I work now.
Yes, I know the problem. My advantage is that I'm semi-retired and self employed.
