Do I need a larger power supply for a 2TB internal harddrive

by beeples / March 23, 2012 2:09 AM PDT

I have an HP Pavillion desktop (model P6157c). I recently replaced my hard drive to a 2TB Seagate Barracuda Green hard drive, 5900 RPM 3.5 Int. ST32005N4A1AS-RK. I'm having problems loading the startup discs. Someone told me I needed a larger UPS. My current UPS is a LiteON model PS-5301-08HA, 300W.

That's PSU not UPS.

I don't see where having a larger HD will make any more demands on power than a smaller capacity HD. In most cases they should stay the same for similar physical sizes. However, if you added a 2nd HD to the original HD, then that will add more demands but even that will be minor. However, the 300W PSU is typical of HP systems and it wouldn't be unkind to replace it with a higher wattage unit just to be safe and happy for the long run. Since, you've replaced the HD in question, you should at least recheck your work and all the connections to be sure they're OK.

Deleted drive D. Can't get recovery discs to install, HELP?

In reply to: I suspect...

This started when I deleted drive D. It then started freezing up alot. So I started trobleshooting, but can't seem to get it right. Desperately need my computer running. Replaced 750Gb HD with a 2Tb HD. Ordered recovery discs from HP since Vista was preinstalled. Disc 1 started fine until it got to where the Recovery Manager was supposed to open, it then stated to "reboot and select proper boot device or insert boot media in selected boot device and press a key". Now that is all I get no matter what I do. Any Suggestions???

Within the bios, be sure thr 1st boot device is the CD/DVD drive. If you have more than one, then its the 1st Cd drive. Once done "saved" before exiting out, do a reboot. It should with the OS install disc mounted, try to boot from it. Now, if you have the proper HP discs then it should proceed to start the install and procedd forth. if it stops then there either some discrepancy as to what it knows is the boot device or the recovery discs just need a longer time in order to error out and what that error states. I assume you have only the 2Tb HD installed as in "alone". It would need to be formatted as the process to do that will take some time, has that gotten to that point. If not, your 2Tb s/w if supplied with the new HD should provide whatever new setup condition is needed in for its use. That requires a format and simple acknowledgement in order to proceed. Once done, then use the install OS discs. if the install discs need to re-format, then allow that procedure for best install. Being a 2Tb disc, it will take some time, but the process should report its being done, again allow it to show some status.

I assume you already resolved any SATA issues, so review them in order now to make this process above take place. Again, the bios should report that status, so review it.

FYI- HP provides a generic recovery procedure, why not get that and print it out. The below link should be of assistance:

This happened to a buddy.

It turns out they had to pull back to a blank 1TB drive since something BIOS or recovery system was not supported on the 2TB drives. It's pretty simple what's wrong. There were no 2TB drives to test with back when this system was made.

I agree it's unlikely to be the PSU.
